  1. The Human Body:An Orientation

  2. The Human Body – An Orientation Introduction • Compare/contrast Anatomy & Physiology. • Are the following considered Gross or Histology? • Anatomy and physiology are always related. Structure determines function. • Levels of organization: • Simplest level is the atomic or chemical level. • Levels of living structure: Cell Tissue Organ System Organism

  3. Levels of Structural Organization Figure 1.1

  4. II. System Overview Integumentary • Skin (External covering) & its derivatives. • Waterproofs, cushions and protects organs, regulates temperature and excretes salts, protects deeper tissue from injury. Figure 1.2a

  5. Organ System Overview Skeletal • Bones, cartilage and ligaments. • Protects, provides framework, movement, stores minerals, produces blood cells. Figure 1.2b

  6. Organ System Overview Muscular • Skeletal muscles. • Movement & produces heat. Figure 1.2c

  7. Organ System Overview Nervous • Nerves, brain and spinal cord. • Fast-acting control system & responds to internal and external change. Figure 1.2d

  8. Organ System Overview Endocrine • Ductless glands. • Controls slow, long lasting processes by producing hormones. Figure 1.2e

  9. Organ System Overview Cardiovascular • Heart, blood and vessels • Transports materials and protects from invaders Figure 1.2f

  10. Organ System Overview Lymphatic • Lymph nodes, lymph and vessels. • Returns fluid to blood and fight infection. Figure 1.2g

  11. Organ System Overview Respiratory • Nose, pharynx, larynx, bronchi, lungs and diaphragm. • Brings in oxygen and removes carbon dioxide. Figure 1.2h

  12. Organ System Overview Digestive • Mouth, esophagus, stomach, SI, LI, liver and pancreas. • Breaks down and absorbs food. Figure 1.2i

  13. Organ System Overview Urinary • Kidneys, ureter, urinary bladder and urethra. • Filters wastes from the blood. Figure 1.2j

  14. Organ System Overview Reproductive • Ovaries, testes and accessory structures. • Produce the gametes for reproduction. Figure 1.2k

  15. III. Necessary Life Functions Characteristics of Living Things • Maintain boundaries • Move • Responsiveness/Irritability • Digestion • Metabolism • Excretion • Growth • Reproduction

  16. III. Necessary Life Functions Survival needs • Food, oxygen, water and appropriate temperature and atmospheric pressure. Feedback • Positive: The response increases the effect of the control mechanism. • Negative: The response stops the effect of the mechanism. (Most common)

  17. III. Necessary Life Functions Control mechanism • Communication within the body is essential for homeostasis. • There are 3 components of a control mechanism. • Receptor: sensor responding to changes. • Control center: determines the maintained level and analyzes the information from receptors to determine proper response. • Effector: The means for the control.

  18. Overview of Homeostasis Figure 1.4

  19. IV. The Language of Anatomy • To prevent misunderstanding, there is a set of terms that allow structures to be easily located. • Anatomical position • In anatomy the body is always assumed to be in this position. • The body standing straight, head and palms forward, arms out to the side.
