    3. Body Organization At A Glance The body is organized into levels Cells Tissues Organs Systems Body

    4. Body Organization At A Glance Each level is built from the one below it Body as a whole is composed of systems A system is composed of organs An organ is composed of tissues A tissue is composed of cells

    5. Body Organization Illustrated

    6. Body Organization Combining Forms • abdomin/o abdomen • adip/o fat • anter/o front • brachi/o arm • cardi/o heart • caud/o tail • cephal/o head • cervic/o neck

    7. Body Organization Combining Forms • chondr/o cartilage • crani/o skull • crin/o to secrete • crur/o leg • cyt/o cell • dermat/o skin • dist/o away from • dors/o back of body

    8. Body Organization Combining Forms • enter/o small intestine • epitheli/o epithelium • gastr/o stomach • glute/o buttock • gynec/o woman • hemat/o blood • hist/o tissue • immun/o protection

    9. Body Organization Combining Forms • infer/o below • laryng/o larynx • later/o side • lumb/o loin • lymph/o lymph • medi/o middle • muscul/o muscle • nephr/o kidney

    10. Body Organization Combining Forms • neur/o nerve • ophthalm/o eye • ot/o ear • pelv/o pelvis • peritone/o peritoneum • pleur/o pleura • poster/o back • proct/o rectum and anus

    11. Body Organization Combining Forms • proxim/o near to • pub/o genital region • pulmon/o lung • rhin/o nose • spin/o spine • super/o above • thorac/o chest • ur/o urine

    12. Body Organization Combining Forms • vascul/o blood vessel • ventr/o belly • vertebr/o vertebra • viscer/o internal organ

    13. Body Organization Suffixes • -ac pertaining to • -al pertaining to • -ar pertaining to • -ary pertaining to • -atic pertaining to • -iac pertaining to • -ic pertaining to • -ior pertaining to

    14. Body Organization Suffixes • -logy study of • -ose resembling

    15. Body Organization Prefixes • endo- within • epi- above • hypo- under • peri- around • retro- behind

    16. Levels of Body Organization Cells form tissues Tissues form organs Organs form systems Systems form whole body

    17. Cells Cyt/o + -logy = cytology • cyt/o + -logy = cytology • The study of cells and their function

    18. Cells • Fundamental unit of life • Has all properties of being alive • Responds to stimuli • Engages in metabolic activity • Reproduces itself • All tissues and organs in body formed of cells

    19. Cells • Individual cells perform functions for body • Reproduction • Hormone secretion • Energy production • Excretion

    20. Cells • Special cells carry out very specific functions • Muscle contraction • Electrical impulse transmission

    21. Cells • Cells come in different sizes and shapes • But all cells,at some point of their life cycle, have • Nucleus • Cytoplasm • Cell membrane

    22. Muscle Contraction Animation Click on the screenshot to view an animation showing muscle contraction. Back to Directory

    23. Figure 2.1Examples of four different types of cells from the body illustrating the differences in shape.

    24. Tissues hist/o + -logy = histology • hist/o -logy = histology • The study of tissue • Formed when like cells are grouped together to perform an activity • Four types of tissue • Muscle tissue • Epithelial tissue • Connective tissue • Nervous tissue

    25. Muscle Tissue • Produces movement in body by contracting • Composed of individual muscle cells called muscle fibers

    26. Muscle Tissue • Three basic types of muscles • Skeletal muscle • attached to bones • Smooth muscle • internal organs like intestine and uterus • Cardiac muscle • only in the heart

    27. Figure 2.2This figure shows the appearance of different types of tissues and their location within the body.

    28. Epithelial Tissue • Known as epithelium • Found as lining for internal organs and covering for the skin • Close-packed cells that function to: • Form a protective barrier – skin • Absorb – lining of intestine • Secrete – sweat glands • Excrete wastes – kidney tubules

    29. Figure 2.2This figure shows the appearance of different types of tissues and their location within the body.

    30. Connective Tissue • Supports and protects • Function depends on location • Many different forms • Adipose • Bone • Cartilage • Tendons

    31. Figure 2.2This figure shows the appearance of different types of tissues and their location within the body.

    32. Nervous Tissue • Composed of cells called neurons • Forms the brain, spinal cord, and nerves • Allows for conduction of electrical impulses between brain and rest of the body

    33. Neuron Animation Click on the screenshot to view an animation showing neurons. Back to Directory

    34. Figure 2.2This figure shows the appearance of different types of tissues and their location within the body.

    35. Organs • Composed of several types of tissue • Work together as a unit • Perform special functions • Example: stomach contains: • Muscle fibers • Nerve tissues • Epithelial tissue

    36. Systems • Composed of several organs working together in coordinated manner • Perform complex functions • Example: stomach plus other digestive organs including mouth, esophagus, liver, pancreas, small intestine, and colon work together to break down, digest, and absorb food

    37. Integumentary System • Two-way barrier and temperature regulation • Organs • Skin • Hair • Nails • Sweat glands • Sebaceous glands

    38. Musculoskeletal System – Skeleton • Supports and protects body, forms blood cells, stores minerals • Organs • Bones • Joints

    39. Musculoskeletal System – Muscles • Produce movement • Organs • Muscles

    40. Cardiovascular System • Pumps blood to transport nutrients, oxygen, and wastes • Organs • Heart • Arteries • Veins

    41. Cardiovascular System Animation Click on the screenshot to view an animation of the cardiovascular system. Back to Directory

    42. Blood (Hematic System) • Transports oxygen, protects, and controls bleeding • Organs • Plasma • Erythrocytes • Leukocytes • Platelets

    43. Lymphatic System • Protects body • Organs • Lymph nodes • Lymphatic vessels • Spleen • Thymus gland • Tonsils

    44. Lymphatic System Animation Click on the screenshot to view an animation of the lymphatic system. Back to Directory

    45. Respiratory System • Obtains oxygen and removes carbon dioxide • Organs • Nasal cavity • Pharynx • Larynx • Trachea • Bronchial tubes • Lungs

    47. Gastrointestinal System • Ingest, digest, and absorb nutrients • Organs • Oral cavity • Pharynx • Esophagus • Stomach • Small intestine • Colon • Liver & gallbladder • Pancreas

    48. Digestive System Animation Click on the screenshot to view an animation of the digestive system. Back to Directory

    49. Urinary System • Filters waste and removes from body • Organs • Kidneys • Ureters • Urinary bladder • Urethra
