SOC 17: The Structure of the Respiratory System

Question 1

Respiration

Answer 1

The movement of air from outside the body into the cells within tissues.

Question 2

Diaphragm

Answer 2

The primary muscle used in the process of inspiration or inhalation

Question 3

Alveoli

Answer 3

Tiny sacs at the end of the bronchioles, where gas exchange takes place

Question 4

Gaseous exchange

Answer 4

The delivery of oxygen from the lungs to the bloodstream and the removal of carbon dioxide from the tissues.

Question 5

Bronchus

Answer 5

Tube along which air passes from the trachea into the lungs.

Question 6

VO2 max

Answer 6

The volume of oxygen an athlete can consume while exercising at maximum capacity.

Question 7

Oxygen debt

Answer 7

The amount of oxygen needed at the end of a physical activity to break down any lactic acid.

Question 8

What makes up the respiratory system ?

Answer 8

It includes the nose , mouse , thoat , voice box , windpipe , lungs and vessels

Question 9

Why do we need our respiratory system ?

Answer 9

To get oxygen into the body
To remove carbon dioxide from the body
In physical activity the respiratory and cardiovascular systems must work closely together to keep the body supplied with oxygen.

Question 10

Inhaled air (inspiration)

Answer 10

20% oxygen and 0.4% carbon dioxide

Question 11

Exhaled air (exhalation)

Answer 11

16% oxygen and 4% carbon dooxide

Question 12

Vital capacity

Answer 12

The greatest amount of air that can pass into and out of the lungs by the most forceful inspiration and expiration

Question 13

Tidal volume

Answer 13

The amount of air inspired and expired with each breath

Question 14

Breathing explained in steps

Answer 14

When breathing in(inhaling, the intercostal muscles ( the muscles between the ribs) contract and lift the chest upwards and outwards while the diaphragm tightens and lowers
The diaphragm changes from a dome shape to a flatter shape when we breathe in
The dihragm relaxes when we breathe out, moving upwards back to a dome shape
These actions open the lungs and create a vacuum inside so that air can rush through the nose and mouth.

Question 15

Once air is inhaled …

Answer 15

The air passes through the larynx and then through the trachea into one of the two branches called the bronchi, through which air passes into either lung.
Smaller branches called bronchioles extend out from the bronchi and at the very ends of these they form millions of tiny sacs called alveoli
In the alveoli, lxygen passes into the blood so it can be transported around the body

Question 16

Trachea

Answer 16

The tube that makes air into the chest , also known as the windpipe

Question 17

Haemoglobin

Answer 17

A type of protein found in every red blood cell

Question 18

Anaerobic exercise

Answer 18

Working at a high intensity level withough oxygen for energy production

Question 19

How do the cardiovascular and respiratory system work together?

Answer 19

An efficient respiratory systmen aids the cardiovascular system by providing a constant suppky of oxygen for the muscles and by removing carbon dioxide.

Question 20

What type of exercise results in oxygen debt?

Answer 20

Anaerobic exercise

Question 21

How is oxygen debt repaid?

Answer 21

Repaid through deep, gasping breaths at the end of an activity.
