1

Pathophysiology

The study of how disease processes affect the function of the body

2

Cell membrane

Out covering of the cell that protects and selectively allows water and other substances into and out of the cell

3

Cell nucleus

The control center of a cell

4

DNA

Deoxyribonucleic acid, a molecule that contains the body's genetic code for reproduction

5

Metabolism

The diversion of glucose to energy

6

Electrolytes

Substances that when dissolved in water separate into charged particles

7

Aerobic metabolism

The cellular process by which oxygen is used to metabolize glucose and energy is produced in an efficient manner with minimal waste products

8

Anaerobic metabolism

The cellular process by which glucose is metabolized without oxygen and energy is produced in an inefficient manner with many waste products

9

Dehydration

An abnormally low amount of water in the body

10

Edema

Swelling associated with the movement of water into the space surrounding the tissues

11

Patent

Open and clear, free from obstruction

12

Tidal volume

The volume of air moved in one breathing cycle, which consists of one inhalation and one exhalation

13

Dead air space

The space between the mouth and alveoli, which is occupied by air that does not actually reach the area of gas exchange

14

Stroke volume (SV)

The volume of blood ejected from the heart in one contraction

15

Cardiac output (CO)

The amount of blood ejected from the heart in one minute

16

Perfusion

The constant supply of oxygen and nutrients to the cells by the flow of blood
