Definition

Anatomy is the structure and relationship of body parts, tissues and cells.

 

Physiology is the function of the body parts

 

They are very intertwined.

Term
Distinguish viruses from prions.
Definition

viruses adopt a crystalline type of structure.

 

prions--> transmissible agents in nervous diseases. Pathogenic forms of normal cells that have been modified, they reproduce by altering the shape of normal protiens

Definition

 

  1. body temperature
  2. oxygen level in tissue and blood

  4. salt content
  5. metabolic waste product levels.

 

Term
define and give an example of negative feedback.
Definition

change that provokes change in the opposite direction to help it get back to its normal level.

 

e.x temperature of body. when its too hot causes sweating, which causes the body to go back to normal.

Term
