 Anatomy  Anatomy: the study of form and structure of the body ( ana = up/apart, tomy = to cut)  Physiology  Physiology: the study of how the body functions ( physio = function, logy = study of)  Function depends on structure!

Anatomy can be studied at different levels. Microscopic Level 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

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

The body’s ability to maintain a stable internal environment.

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

 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

 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

 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  I will print them out for your notes

 Necessary life functions  Maintaining boundaries  Movement  Responsiveness/irritability  Digestion  Metabolism  Excretion  Reproduction  Growth

 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!!
