Respiratory System

Question 1

Cellular respiratory is

Answer 1

a process that involves breaking down glucose so that energy is released in a form that your cells can use. This reaction produces carbon dioxide as a waste product that needs to be removed.

Question 2

What is the equation?

Answer 2

glucose + oxygen → carbon dioxide + water + energy

Question 3

What is the respiratory system?

Answer 3

It involves the lungs and associated structures, which take in air and supply the blood with oxygen to deliver to the body’s cells so they can carry out their essential functions;
it also performs gas exchange to remove the waste gas carbon dioxide

Question 4

The respiratory system is made up of

Answer 4

trachea (or windpipe) and lungs

Question 5

Trachea is

Answer 5

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

Question 6

Bronchi are

Answer 6

the narrow tubes through which air passes from the trachea to the smaller bronchioles and alveoli in the respiratory system

Question 7

Bronchioles are

Answer 7

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

Question 8

Alveoli are

Answer 8

tiny air sacs in the lungs at the ends of the narrowest tubes. Oxygen moves from alveoli into the surrounding blood vessels, in exchange for carbon dioxide.

It is at the alveoli that gases (such as oxygen and carbon dioxide) are exchanged between the respiratory system and the circulatory system.

Question 9

What is asthma?

Answer 9

The narrowing of the air pipes that join the mouth and nose to the lungs

Question 10

Which pipes are the most affected?

Answer 10

The bronchi. They become narrower as:

• the muscle wall of the air pipes contracts
• the lining of the air pipes swells
• too much mucus is produced.

Question 11

What are the chemicals in cigarettes?

Answer 11

Carcinogens, and they cause lung cancer

Examples include acetone, cyanide, methanol, arsenic and vinyl chloride
