Biology

Front 1

Nasal Cavity

Back 1

Filter, Warm and moisten the air entering lungs.

Front 2

Mucus Membrane

Back 2

Secrete sticky mucus to trap germs and debris.

Front 3

Lacrimal (tear)

Back 3

Drain into the nasal cavity causing a stuffy nose when crying.

Front 4

Sinusitis

Back 4

Infection of the sinuses.

Front 5

Sinus Headache

Back 5

May occur when a cold or an allergic reaction blocks the duct leading from sinuses.

Front 6

Pharynx

Back 6

Located behind the uvula and is a passageway for air, liquids, and foods.

Front 7

Larynx

Back 7

Voice box used to generate sound epiglottis closes trachea when swallowing wide vocal cord account for deep voice of male.

Front 8

Trachea

Back 8

Windpipe held by concentric rings of cariliage located ventral to esophagus.

Front 9

Cilia

Back 9

Sweeps mucus, germ and debris toward throat.

Front 10

Tracheostomy

Back 10

breathing tube may be inserted into the trachea when a person is choking due to blocked wind pipe.

Front 11

Bronchial Tree

Back 11

Trachea - Bronchii- bronchioles - alveoli (air sacs)

Front 12

Bronchittis

Back 12

Infection of the bronchial tubes, constrict and fill with mucus.

Front 13

Epiglottis

Back 13

closes traches when swallowing wide.

Front 14

Lungs

Back 14

Have about 300 million alveoli and are found in the thoracic cavity.

Front 15

Pleura

Back 15

2 Serious membranes one covers the outside of the lungs and the other one lines the pleural cavity.

Front 16

Pleurisy

Back 16

inflammation of the pleura.

Front 17

Alveoli

Back 17

The aveolar sac is surrounded by blood cappilaries where the exchange of gases occur.

Front 18

Vidal Capacity

Back 18

Max volume of air that can be moved in and out during a single breath.

Front 19

Tidal Volume

Back 19

Amount of air normally moved in the human body during an inspiration of experation.

Front 20

Residual Volume

Back 20

Amount of air remaining in the lungs after a forceful expiration.

Front 21

Inspiration

Back 21

The thoracic cavity and Lungs expand so that air is drawn in.

Front 22

Rib Cage

Back 22

Moves protects lungs and moves air up and out.

Front 23

Diaphragm

Back 23

Dome shaped Muscle contract ands moves air down. Pressure in lungs decrease and air comes rushing in.

Front 24

Expiration

Back 24

Thoracic cavity and lungs resume their original position and pressure.

Front 25

Rib cage

Back 25

Moves air up and in.

Front 26

Diaphragm

Back 26

Relaxes and moves air up. Pressure in the lungs decrease.

Front 27

Medulla Oblingata

Back 27

Sends out impulses to the Diaphragm and external entercoastal.

Front 28

Chemical Input

Back 28

The amount of CO2 in the blood controls the rate and depth of breathing.

Front 29

Chemoreceptors

Back 29

Sensitive to decreased levels of O2 in the blood, communicate with respiratory center to increase.

Front 30

External Respiration

Back 30

Exchange of gases between the atmosphere and the blood.

O2 enters the blood
Co2 leaves the blood.

Front 31

Internal Respiration

Back 31

Exchange of gases between the blood and tissue fluid.

O2 leaves Blood
CO2 enters blood
Hemoglobin gives up Oxygen, Most Co2 is carried as a bicarbonate ions.

Front 32

Upper Respiratory Infections (A) Ottis Medina
(B) Tonsilitis

Back 32

(A) Middle ear Infection.
(B) Inflammtion of tonsils.

Front 33

Pneumonia

Back 33

Infection of lower respiratory tract, Infection of lungs.

Front 34

Pulmonary Tuberculosis

Back 34

Lower Respiratory, Bacterial infection of lungs.

Front 35

Chronic Bronchitis

Back 35

Lower Respiratory, Airways inflammed and filled with mucus.

Front 36

Emphysema

Back 36

Chronic and incurable disorder where the surface are available for gas exchange.

Front 37

Asthma

Back 37

Lower Respiratory, Disease of the bronchii and bronchioles marked by wheezing breathlessness.

Front 38

Lung Cancer

Back 38

More preventable in men thean in woman.
