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!

Subdivisions of A&P Anatomy can be studied at different

levels.1) Microscopic Level:micro= smallscope = to viewExamples:

cytology (cyto = cell; logy = study of)

histology (histo = tissue; ology = study)

the study of structures that are not visible to the

unaided eye

Subdivisions of A&P2) Gross Level: immediately noticeable, NOT disgusting

~Involves dissection

the study of large structures such as organs or bones or

tissues, etc.

3) Systemic Anatomy – the study of the components of an organ system.

HOMEOSTASIS #4https://www.youtube.com/watch?v=XZxuQo3ylII

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

stimulus

Components of Homeostasis

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

Negative Feedback The body senses an

internal change and activates mechanisms that reverse, or negate, that change.

Examples include: Body temperatureBlood sugar

concentrationWater balancepH concentrations

Positive Feedback a process in which the

body senses a change and activates mechanisms that accelerate or increase that change

Examples include: Blood clottingOxytocin released

during child birth

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

Survival NeedsNutrients (carbohydrates, proteins, fats, minerals and vitamins)

Water: 60-80% body weightOxygen: 20% of air we breatheAppropriate temperature: 98 degrees; cooler slows metabolism

Appropriate atmospheric pressure for breathing (high altitudes, thin air)
