1/17

diaphragmA large, dome-shaped muscle that

plays an important role in breathing.

ciliaTiny hair-like extensions of cells that

can move together like whips.

bronchitis

An irritation of the breathingpassages in whichthe small passagesbecome narrower than normal and

may be clogged withmucus.


2/17

asthmaA disorder in which the respiratory

passages narrow significantly.

diffusionThe process by which molecules

move from an area in which they are

less concentrated, from high

pressure to low pressure.

capillary

(pl. capillaries)


3/17

A tiny blood vessel where substances

are exchanged between the blood

and the body cells. Its wall is one cell

thick which makes it easy for gasexchange to take place.

epiglottisA flap of tissue that seals off the

windpipe and prevents food from

entering.

larynx

The voice box, located in the top part of

trachea, underneath the epiglottis.


4/17

mucusA thick, slippery substance produced

by the body.

hemoglobinAn iron-containing protein that binds

chemically to oxygen molecules and

makes up most of red blood cells.

reflexAn automatic response that occursvery rapidly and without conscious

control.


5/17

pharynxThe throat; part of both the

respiratory and digestive systems.

respirationThe process in which oxygen and

glucose undergo a complex series of

chemical reactions inside cells.

tracheaThe windpipe; a passage throughwhich air moves in the respiratory

system.


6/17

vaccination

The process by which harmless

antigens are deliberately introduced

into a persons body to produce

active immunity.

vaccine

(pl. vaccines)A substance used in a vaccinationthat consists of pathogens that have

been weakened or killed but can still

trigger the immune system intoaction.

pleura


7/17

The delicate membrane that lines

the ribcage and is folded back over

the surface of the lung.

bronchiole

(pl. bronchioli)

A thin-walled branch of bronchus

that conducts air to the alveoli.


8/17

inflateTo fill with air or gas so as to make it

swell.

deflateTo release air or gas.

lungsThe main organs of the respiratory

system. Your lungs are a pair of large

sponge-like organs that almost fill your

chest cavity. Your left lung is slightlysmaller than your right lung, to make

space for your heart. The right lung has

3 lobes while the left lung has 2 lobes.


9/17

lymph nodeLymph nodes are small, bean-shaped glands throughout

the body. They are part of the lymphatic system, which

carries fluid (lymph fluid), nutrients, and waste material

between the body tissues and the bloodstream. The

lymphatic system is an important part of the immune

system, the body's defense system against disease. The

lymph nodes filter lymph fluid as it flows through them,

trapping bacteria, viruses, and other foreign substances,

which are then destroyed by special white blood cells

called lymphocytes.

to breathe(v)To inhale and exhale air.

10/17

An act of breathing where air is

inhaled and exhaled.

T cell

A lymphocyte that identifies

pathogens and distinguishes one

pathogen from the other.

lymphocyteA smallwhite blood cell (leukocyte) that plays a

large role in defending the body against disease.

Lymphocytes are responsible

for immune responses. There are two main types

of lymphocytes: B cells and T cells. The B cells

make antibodies that attack bacteria and toxins

while the T cells attack body cells themselves whenthey have been taken over by viruses or have

become cancerous.

11/17

carbon monoxide

(CO)A colorless, odorless and toxic gas

produced when substances,

including tobacco, are burned. It ispresent in exhaust fumes. Because it

is impossible to see, taste or smell

the toxic fumes, CO can kill you

before you are aware it is in your

home.

infectious disease

A disease that can pass from oneorganism to another.


12/17

passive smoking

The involuntary inhalation of smoke

from other peoples cigarettes,

cigars, or pipes.

red blood cellA cell in the blood that takes upoxygen in the lungs and delivers it to

cells elsewhere in the body.

white blood cell

A blood cell that fights disease. See

lymphocytes.

gas exchange


13/17

The exchange of oxygen and carbon

dioxide.

to relaxto loosen, rest, or alleviate

to contractto become smaller in size (shrink,compress, decrease)


14/17

alveolus

(pl. alveoli)Tiny sacs of lung tissue specialized

for the movement of gasses between

the air and the blood.

bronchus

(pl. bronchi)

The passages that branch from the

trachea and direct air into the lungs.

pathogen


15/17

(pl. pathogens)

An organism that causes disease.

emphysemaA serious disease that destroys lung

tissue and causes difficulty in

breathing.

antibodies


16/17

Antibodies are proteins that are

found in blood or other bodily fluids,

and are used by the immune system

to identify and neutralize foreignobjects, such as bacteria and

viruses.

(adj. viral)Viruses are tiny organismsthat may lead to mild tosevere illnesses in humans.

This may include the flu ora cold to something morelife threateninglike HIV/AIDS.
