Soc 17- Respiratiry System

Question 1

What does it include?

Answer 1

Nose,mouth,throat,voice box, windpipe, lungs and blood vessels

Question 2

Why do we need our respiratory system?

Answer 2

-to get oxygen into our body
-to remove carbon dioxide from the body
-in sports respiratory and cardiovascular system must work together to keep your body supplied with oxygen

Question 3

Inspiration;breathing in

Answer 3

20% oxygen + 0.4% carbon dioxide

Question 4

Exhalation: breathing out

Answer 4

16% oxygen + 4% carbon dioxide

Question 5

Vital capacity meaning

Answer 5

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

Question 6

Tidal volume meaning

Answer 6

is the amount of air inspired and expired with each
breath

Question 7

How does breathing work

Answer 7

• 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 diaphragm 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 8

What happens once inhaled?

Answer 8

• 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, oxygen passes into the blood so it can be
  transported around the body.

Question 9

Gaseous exchange process

Answer 9

The alveoli are surrounded by capillaries (very narrow tubes) that carry blood.
- Haemoglobin inside red blood cells binds to oxygen, which diffuses into the
blood so it can be transported around the body to be deposited in the living
cells.
- A series of chemical reactions take place, which combines glucose (from food)
with oxygen to release energy, along with carbon dioxide and water.
- While oxygen is taken in carbon dioxide is given out, or exchanged, into the
alveoli and is then breathed out.

Question 10

What is oxygen debt and how it happens

Answer 10

Oxygen Debt: The amount of oxygen needed at the end of a
physical activity to break down any lactic acid.
- Anaerobic exercise often results in oxygen debt.
- This is the amount of oxygen needed to oxidise lactic acid to
carbon dioxide and water.
-repaid through deep breaths which allows a lot of oxyegn into respiratory system while elimanating carbon dioxide

Question 11

Defenition of respiration

Answer 11

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

Question 12

Defenition of diaphragm

Answer 12

The ptimary muscle used in the process of inspiration, inhalation. A dome-shaped sheet of muscle that seperates the chest from the rest of yhe body cavity

Question 13

Defeniton of trachea

Answer 13

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

Question 14

Defeniton of bronchus

Answer 14

Tube along which air passes from trachea into lungs

Question 15

Dfeneiton of bronchioles

Answer 15

Smaller branches coming of the bronchi

Question 16

Dfeneition of alveoli

Answer 16

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

Question 17

Defenition of haemoglobin

Answer 17

A type of portein found in every red blood cell

Question 18

Defeniton of gaseous exchange

Answer 18

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

Question 19

Dfeneiton of VO2 max

Answer 19

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

Question 20

How does the respiratory system and the cardiovascular system work together

Answer 20

An efficient respiratory system aids the cardiovascular system
by providing a constant supply of oxygen for the muscles and
by removing carbon dioxide.
During exercise, the body needs to take in a sufficient amount
of oxygen and eliminate the carbon dioxide produced by the
muscles while they are working.
