Anatomy and Physiology: Understanding Life's Functions and Metabolism

Explore the structure and function of the human body, learn about the characteristics of life, metabolism, and homeostasis. Discover how the body maintains balance and responds to internal and external stimuli. Dive into organ systems and the mechanisms of negative and positive feedback control systems.

Presentation Transcript

  1. AP Ch 1 Learning Targets

  2. LT 1-3 • 1. Differentiate between anatomy & physiology • 2. List and explain the functions necessary for maintaining life (characteristics of life) • 3. Define metabolism and apply this term to the characteristics of life

  3. Anatomy-structurephysiology- function

  4. LT #2-3 • Characteristics of Life • Movement - self initiated change in position, motion of internal parts • Responsiveness (irritability) - Ability to sense changes and react to them • Growth - increase in body size • Reproduction - Parents produce offspring / producing new individuals • Respiration - Obtaining oxygen (O2), using it to release energy from food substances, and getting rid of wastes • Digestion - Chemically changing (breaking down) food substances, and getting rid of wastes • Circulation - Movement of substances throughout the body • Excretion - Removal of wastes • METABOLISM:: All physical and chemical changes occurring in an organism • HOMEOSTASIS: Tendency of the body to maintain a stable, balanced internal environment. Accomplished by 11 body systems (LT 11)

  5. Metabolic processes

  6. Anatomy vs Physiology?

  7. LT 4-levels of organizaion

  8. LT 5-Organ systems

  9. Give it a try!

  10. Explain the mechanisms of actions of negative and positive feedback control systems • Sweat, shiverChild birth • Eat, drink (most)Blood clotting

  11. Disease
