Unit #1Human Body
Overview of A&PBiology – Study of life
Anatomy – study of the structure and shape of the body and its parts and their relationship to one another (gross vs. microscopic)
Physiology – study of how the body and its parts work or function
How are they related?

Needs for Life
1. Maintain self – inside/outside2. Movement – mainly of self, but also ‘things’ inside3. Responsiveness – ability to sense changes AND react4. Digestion – breaking down particles to usable forms5. Metabolism – broad term for all RXNs that occurs in cells6. Excretion – must get ride of BAD (solid and waste)7. Reproduction – continuation of species8. Growth – increase in size by increasing the number of cells9. Nutrients – in the form of some type of food10.Oxygen11.Water – 60-80% of the human body12.Temperature regulation13.Atmospheric pressure
Homeostasis-maintaining a constant internal balance- Feedback systems are in place

Body Planes & Sections
Sagittal – runs up and down, if it splits the body in half exactly it is called midsagittal, if it splits the body into two unequal halves it’s called parasagittal
Frontal – gives you a front and back (anterior and posterior), also called coronal
Transverse – gives you a top and bottom (superior and inferior)
Refer to page 19, figure 1.6
Body CavitiesDorsal (split into cranial and spinal)
Ventral (greater in size) (split into thoracic and abdominopelvic)
- Abdominopelvic can be further divided into 4 quadrants- Refer to figure 1.8
