Digestion

Front 1

Pharynx

Back 1

Connects the mouth and nasal cavity to the larynx and eshopagus . serves as the passageway for air into the respitoary system and food for the digestive system. also known as the throat.

Front 2

Pleural Membrane

Back 2

double layered membrane that encloses the lungs; also reffered to as the pleura

Front 3

Thoracic cavity

Back 3

The thoracic cavity (or chest cavity) is the chamber of the human body (and other animal bodies) that is protected by the thoracic wall (thoracic cage and associated skin, muscle, and fascia).

Front 4

trechea

Back 4

in vertebrates tube that carries air from the nasal passages or mouth to lungs also known as windpipe

Front 5

Alveoli

Back 5

gas exchange structure within mammalian lungs tiny air pocket with walls made of a membrane that is a single cell thick allowing for exchange of respitoary gasses.

Front 6

bronchiole

Back 6

the passage way that branches from the treachea into the lungs, with one bronchus carrying air into each lung

Front 7

diaphgram

Back 7

muscular layer that seperates the region of the lungs, from the region of the stomach and liver

Front 8

epiglottis

Back 8

flap of cartilage located over the entrance to the trechea. closes during swallowing to prevent food from entering the respitory tract.

Front 9

glottis

Back 9

the opening of the trechea through which air enters the larynx

Front 10

larynx

Back 10

a structure within the upper respitoary tract that contains the vocal cords commomnly known as the voice box

Front 11

nasal passages

Back 11

passage from the nostrils to the back of the throat which air enters the body, serves to warm, moisten and clean incomming air lined with cilliated cells and mucus secreting cells.

Front 12

spirograph

Back 12

graph representing the amount of air that moves into and out of the lungs with each breath

Front 13

tidal volume

Back 13

volume of air that is inhaled and exhaled in a normal breathing movement when the body is at rest

Front 14

inspitoary reserve volume

Back 14

additonal volume of air that can be taken in by the lungs beyond a regular or tidal inhaliation

Front 15

expatory reserve volume

Back 15

additonal volume of the air than can be forced out of the lungs beyond a regular or tidal exhalation

Front 16

vital capacity

Back 16

the total volume of gas that can be moved in our out of the lungs, equal to tidal volume + inspitaory volume + expitoary volume also known as total lung capaciaty volume

Front 17

residual volume

Back 17

amount of gas that remains in the lungs and the passageways of the respitoary system even after full exhalation

Front 18

external repsiration

Back 18

exchange of oxygen and carbon dioxide between the air and the blood takes place in the

Front 19

internal repsiration

Back 19

exhange of oxygen and carbon dioxide between the bodys tissue cells and the blood

Front 20

nostril

Back 20

is one of the 2 channels of the nose
