  2. Assignment #2: Lecture 1.1What is Anatomy & Physiology? • Anatomy: the study of form and structure of the body (ana = up/apart, tomy = to cut) • Physiology: the study of how the body functions (physio= function, logy= study of) • Function depends on structure!

  3. Subdivisions of A&P • Anatomy can be studied at different levels. 1) Microscopic Level: micro= small scope= to view Examples: • cytology (cyto= cell; logy= study of) • histology (histo= tissue; ology = study) the study of structures that are not visible to the unaided eye

  4. Subdivisions of A&P the study of large structures such as organs or bones or tissues, etc. 2)Gross Level: immediately noticeable, NOT disgusting ~Involves dissection 3)Systemic Anatomy – the study of the components of an organ system.

  5. Organizational Hierarchy of the Human Body Leave room to list them… Nervous Muscular Epithelial Connective Smallest units capable of life functions Not living Molecules & Atoms Organelles

  6. Human Body Systems

  7. HOMEOSTASIS #4 https://www.youtube.com/watch?v=XZxuQo3ylII The body’s ability to maintain a stable internal environment.

  8. Components of Homeostasis Analyzes info and determines the needed response Monitors environment and sends info to control center Effector Provides the appropriate response as dictated by the control center stimulus

  9. Negative Feedback • The body senses an internal change and activates mechanisms that reverse, or negate, that change. • Examples include: • Body temperature • Blood sugar concentration • Water balance • pH concentrations

  10. Positive Feedback • a process in which the body senses a change and activates mechanisms that accelerate or increase that change • Examples include: • Blood clotting • Oxytocin released during child birth

  11. Assignment • Find a picture that represents each type of feedback. • Create a google doc to put your pictures in. • Write a caption for each. • Share with lsupernavage@unionacademy.org • I will print them out for your notes

  12. #7: Maintaining Life • Necessary life functions • Maintaining boundaries • Movement • Responsiveness/irritability • Digestion • Metabolism • Excretion • Reproduction • Growth

  13. Survival Needs • Nutrients (carbohydrates, proteins, fats, minerals and vitamins) • Water: 60-80% body weight • Oxygen: 20% of air we breathe • Appropriate temperature: 98 degrees; cooler slows metabolism • Appropriate atmospheric pressure for breathing (high altitudes, thin air) • TOMORROW: VOMIT LAB!!
