Flashcards in Respiratory system Deck (13):
1

oxygen

a gas in the air (and water) that animals need to breathe in; made up of particles with two oxygen atoms.

2

cellular respiration

the chemical reaction involving oxygen that moves the energy in glucose into the compound ATP. The body is able to use the energy contained in ATP.

3

glucose

a simple carbohydrate and the simplest form of sugar.

4

carbon dioxide

a gas in the air produced by respiration.

5

respiratory system

the body system involving the lungs and associated structures, which take in air and supply the blood with oxygen to deliver to the body’s cells

6

trachea

narrow tube from the mouth to the lungs through which air moves.

7

lungs

the organ for breathing air.

8

bronchi

the narrow tubes through which air passes from the trachea to the smaller bronchioles and alveoli.

9

bronchioles

small branching tubes in the lungs leading from the two larger bronchi to the alveoli.

10

alveoli

tiny air sacs in the lungs at the ends of the narrowest tubes.

11

diaphragm

flexible, dome-shaped, muscular layer separating the chest and the abdomen. It is involved in breathing.

12

vital capacity

the largest volume of air that can be breathed in or out at one time.

13

Breathing

movement of muscles in the chest causing air to enter the lungs and the altered air in the lungs to leave.
