  1. Find Someone Who………… • Goal = get as many signatures as possible! • (1 person can only sign up to 2 times on your sheet)

  2. What do you know?? • Write a definition of anatomy and physiology (two separate definitions).

  3. Objectives: Lesson 1 • TSWBAT define anatomy and physiology and sub-divisions. • TSWBAT evaluate how anatomy and physiology are closely related.

  4. Overview of Anatomy • Anatomy is…………. • the study of the structureand shape of the body • Includes both internal and external structures of the body

  5. Andreas Vesalius- Father of Human Anatomy 1514-1564 A Belgian physician, Andreas Vesalius, was the first to dissect human bodies to study anatomy. He wrote a book on human anatomy in 1538. This book was the first accurate description of the interior of the human body.

  6. 2 Main Divisions of Anatomy I. Gross Anatomy Concerned with those structures in the body large enough to be seen with the naked eye. II. Microscopic Anatomy A microscope or magnifying instrument is used to see very small structures in the body.

  7. Forms of Gross Anatomy • Surface – the study of general form and superficial markings • Regional – focuses on the anatomical organization of specific areas of the body (head, neck, trunk) • Systematic – study of the structure of organ systems (skeletal system) • Developmental – describes the changes in form that occur between conception and physical maturity • Clinical – subspecialties in clinical practice (surgical anatomy)

  8. Subdivisions of the Study of Anatomy: Microscopic Anatomy • Cytology – study of the cell (simplest units of life) Histology – study of tissues

  9. Physiology • Physiology - the study of the functions of the body, often at the cellular or molecular level. Physio = nature Ology = the study of

  10. Sub-groups of Physiology Considers the operation of specific organ systemsCardiovascular physiology is the study of?Neurophysiology is the study of?Renal physiology is the study of?Respiratory physiology is the study of?Pathophysiology is the study of?Exercise physiology is the study of?

  11. Relationship between Anatomy and Physiology • Anatomy and Physiology are alwaysrelated • All specific functions are performed by specific structures. • Structure therefore, determines function Example: A loss of a particular cell type brings on diabetes. Diabetes effects the system (Anatomy) and the function (Physiology).

  12. Real world application – doctor visit • Physicians normally use a combination of anatomical, physiological, chemical, and psychological information when they evaluate a patient • When a patient presents symptoms; the physician will look at the structures affected (Gross anatomy) • Collect a fluid or tissue sample (Microscopic anatomy) • Evaluates your physiological processes by asking questions

  13. Anatomy and Physiology Relationship • An anatomist and a physiologist are asked to examine a car and report their findings. What would an anatomist do? What would a physiologist do?

  14. Ticket out • Describe how anatomy and physiology are closely related? How are they different? Use an example of an electronic device in your rationale.

  15. Introduction to Anatomy – Lesson 2 • TSWBAT list the levels of structural organization.

  16. Levels of Structural Organization • Chemical (or molecular level) • Cellular • Tissue • Organ • Organ System • Organism

  17. Levels of Structural Organization 1. Chemical – Atoms (smallest stable units of matter) combined to form molecules (complex shapes of two or more atoms). 2. Cellular – Molecules interact to form organelles. Organelles are components of cells (smallest living units in the body. 3. Tissue – Groups of similar cells that have a common function. (example – cardiac muscle cells)

  18. Levels of Structural Organization 4. Organ – A structure that is composed of two or more tissue types and performs a specific function for the body (example – cardiac muscle tissue). 5. Organ System – A group of organs that cooperate to accomplish a common purpose (example – cardiovascular system; heart, blood, blood vessels).

  19. Levels of Structural Organization 6. Organism – Made up of the organ systems. Highest level of structural organization (example – human).

  20. Levels of Structural Organization Smooth muscle cell Molecules Cellular levelCells are made up of molecules 2 Atoms Chemical levelAtoms combine to form molecules 1 Smooth muscle tissue Heart Tissue levelTissues consist of similar types of cells 3 Cardiovascular system Blood vessels Epithelial tissue Smooth muscle tissue Blood vessel (organ) Organismal levelThe human organism is made up of many organ systems 6 Connective tissue Organ levelOrgans are made up of different types of tissues 4 Organ system levelOrgan systems consist of different organs that work together closely 5 Figure 1.1

  21. Anatomy – • Hand in Homework – Folder on counter • Read Cell Article (do not write on)

  22. 2. Which levels of structural organization are you unable to see with your naked eye? • 3.Which level of structural organization is composed of two or more different types of tissues that work together to perform a specific function? • 4. How are organs and tissues different? 1. Two or more atoms join together to form what organizational structures?

  23. Intro to Anatomy – Lesson 3 • TSWBAT to identify the 11 body systems and define the functions and components of each system.

  24. Organ Systems of the Body - Skeletal • Protects body organs • Provides the framework for muscles • Forms blood cells • Stores minerals (calcium) Composed of: bones, cartilage, ligaments, and bone marrow

  25. Organ Systems of the Body – Nervous • Directs immediate responses to stimuli • Coordinates or moderates activities of organ systems • Interprets sensory information Composed of: the brain, spinal cord, sense organs and nerves

  26. Organ Systems of the Body - Lymphatic • Picks up fluid leaked from blood vessels and returns it to blood • Defends against infection and diseases Composed of: thymus, spleen, tonsils, lymph nodes, and lymphatic vessels

  27. Organ Systems of the Body - Muscular • Provides movement • Support - Maintains posture - Produces heat Composed of: muscles and tendons

  28. Organ Systems of the Body- Integumentary • Protects • Helps regulate body temperature • Provides sensory information Composed of: the skin, sweat glands, hair, and nails

  29. Organ Systems of the Body - Digestive • Breaks down food into absorbable units • Absorbs and conserves water • Stores energy reserves Composed of: the oral cavity, teeth, tongue, esophagus, stomach, small intestine, large intestine, rectum, anus, liver, gallbladder, and pancreas

  30. Organ Systems of the Body – Endocrine System Not connected anatomically in the same way that parts of other organ systems are. Regulate processes such as growth, reproduction, and nutrient use by body cells. • Composed of: Pineal gland, Pituitary gland, Thyroid gland, Thymus gland, Adrenal gland, Pancreas, Testis (male), Ovary (female)

  31. Organ Systems of the Body - Respiratory • Keeps blood supplied with oxygen and removes carbon dioxide • Produces sound for communication Composed of: the nasal cavity, sinuses, pharynx, trachea, bronchi, larynx and lungs

  32. Organ Systems of the Body - Cardiovascular • Distributes blood cells, water, and dissolved materials, including nutrients, waste products, oxygen, and carbon dioxide Composed of: the heart, blood, and blood vessels

  33. Organ Systems of the Body- Urinary • Eliminates wastes from the body • Maintains the electrolyte balance and regulates the acid-base balance of the blood. Composed of: kidneys, ureters, urinary bladder, and urethra

  34. Organ Systems of the BodyFemale Reproductive • Composed of: mammary glands, ovaries, uterine tubes, uterus, and vagina Main function is the production of offspring

  35. Organ Systems of the BodyMale Reproductive Main function is the production of offspring • Composed of: epididymis, seminal vesicle, prostate gland, penis, testes, scrotum, and vas deferens

  36. System Cooperation Body systems must work together for humans to function properly: EX #1 – Integumentary system & Skeletal System…The skin protects all organs & bones, and also produces vitamin D. Vitamin D is used for proper absorption of calcium. Calcium is needed for proper bone growth/development. Not enough Vitamin D, not enough Calcium absorbed  weak/broken bones!

  37. System Cooperation EX #2: Respiratory system & Circulatory system: Lungs take in oxygen in exchange for carbon dioxide. Alveoli in the lungs give oxygen to red blood cells (hemoglobin) to carry to all parts of the body for respiration. If alveoi are affected, not enough oxygen is taken in and respiration slows  decrease in the amount of energy produced

  38. Organ Systems Don’t Work Alone The respiratory system takes in oxygen and removes waste gases. The cardiovascular system is responsible for delivering the oxygen to all parts of our bodies.

  39. Organ Systems Interrelationships • Nutrients and oxygen are distributed by the blood • Metabolic wastes are eliminated by the urinary and respiratory systems Figure 1.2

  40. Create Want Ad • CHOOSE A BODY SYSTEM •  WRITE EITHER A “FOR SALE” OR “WANTED TO BUY” AD FOR THAT SYSTEM. •  AD MUST INCLUDE PURPOSE/FUNCTION AND PARTS OF THE SYSTEM. •  WRITE IN AD FORMAT (25 +/- WORDS IN LENGTH) • Grading: Content = 15 pts (Purpose, Function & Parts); Creativity = 5 pts

  41. Survival Need or Necessary Life Function? • Metabolism • Nutrients • Reproduction • Oxygen • Water • Maintaining Boundaries • Excretion • Normal Body Temperature • Responsiveness • Atmospheric Pressure • Movement • Growth • Digestion

  42. Intro to Anatomy – Lesson 4 • TSWBAT identify the eight necessary life functions and five survival needs that are necessary for an organism to sustain life.

  43. Necessary Life Functions and Survival Needs • Organisms must be able to carry out various functions in order to maintain life. • If any of these necessary functions are disrupted, the organism may not survive. • Organisms have several survival needs that must be present in order to sustain life.

  44. Necessary Life Functions I • Maintaining boundaries – the internal environment remains distinct from the external environment. A. Cellular level – accomplished by plasma membranes B.Organismal level – accomplished by the integumentary system

  45. Necessary Life Functions I 2. Movement– locomotion, propulsion , and contractility I.E: All of the activities promoted by the muscular system as well as the movement of substances such as blood, food, and urine.

  46. Necessary Life Functions I • 3. Responsiveness (Irritability) – the body’s ability to sense changes in its environment and then react to them • I.E. If you touch a hot burner you will involuntarily pull your hand away from the painful stimulus (fire). • I.E. When the amount of carbon dioxide in your blood rises to dangerously high levels, your breathing rate speeds up to blow off the excess carbon dioxide.

  47. Necessary Life Functions I • Digestion – breakdown of ingested food into simple molecules that can be absorbed into the blood. • Metabolism– refers to all chemical reactions that occur within body cells. Regulates the ability to convert nutrients to energy. • 6. Excretion – removal of wastes from the body • 7. Reproduction – cellular and organismal levels • Cellular – an original cell divides and produces two identical daughter cells that may be used for body growth or repair • Organismal – sperm and egg unite to make a whole new person • 8. Growth – increase in size of a body part or of the organism

  48. 5 Survival Needs – The goal of all body systems is to maintain life. Several factors need to be available for this to occur. • 1. Nutrients • Chemical substances used for energy and cell building. • 2. Oxygen • Needed for metabolic reactions (human cells can only survive for a few seconds without it).

  49. 5 Survival Needs • 3. Water • Provides the necessary environment for chemical reactions. Accounts for 60-80 percent of body weight. • 4. Normal body temperature • Necessary for chemical reactions to occur at life-sustaining rates. For good health, body temperature must be maintained at or around 98 degrees.

  50. 5 Survival Needs • 5. Atmospheric pressureRequired for proper breathing and gas exchange in the lungs.
