Soc17 structure of the Respiratory system

Question 1

What is the route of oxgyen into the lungs

Answer 1

• passes through the trachea
• goes into the bronchus
• goes into the bronchioles
• goes into the alveoli

Question 2

What are the 2 waste products pf exercise?

Answer 2

Co2

Question 3

How is lactic acid broken down?

Answer 3

Using oxygen

Question 4

What is vital capacity?

Answer 4

Greatest amount of air that can be passed into and out of the lungs

Question 5

What is tidal volume?

Answer 5

Amount of air inspired and expired with each normal breath at rest or during exercise.

Question 6

3 ways exercise benifit the respiratory system?

Answer 6

• more efficient at removing co2
• more alveloi becomes avaliable for gas exchange
• inproved efficicienty of the ways will allow better delivery of CO2 to working muscles(body able to cope better during exercise)

Question 7

What is the percentage of gases in inhled air?

Answer 7

• 20% oxygen

- 0.4 Co2

Question 8

What are the percentage of gases exhaled?

Answer 8

16% oxygen

4% CO2

Question 9

What is oxygen dept?

Answer 9

Amount of oxygen needed to break down lactic acid, CO2 and water

Question 10

What is respiration?

Answer 10

Movement of aor from outside the body to cells within tissues.

Question 11

What is the diaphragm?

Answer 11

Primary muscle in inhalation- dome shaped sheet of muscle that seperwtes the the chest from the rest of the body.

Question 12

What is the trachea?

Answer 12

Tube that takes air into the chest (known as the windpipe)

Question 13

What is the Bronchus?

Answer 13

Tube that along which air passes from the trachea to the lungs

Question 14

What are the bronchioles?

Answer 14

Smaller bracnhes coming of the bonchi

Question 15

What are alveoli?

Answer 15

Small sacks at the end of the Bronchioles, where gas exchange takes place.

Question 16

What does the diaphram do when we breath in?

Answer 16

Intercostal muscles contract and lift chest up. Diaphram tightens and lowere (changes from dome to flatter shape)

Question 17

What does the diaphram do when we breath out?

Answer 17

Riaphram relaxes(goes from flatter to dome)

Question 18

Why is air warmed and moisterised?

Answer 18

To allow diffusion to occur

Question 19

What is tidal capacity?

Answer 19

The amount of air breathed in or out of the lungs in one breath

Question 20

What are the four ways exercise impacts the respiratory system?

Answer 20

1. More alveoli become available for Gad exchange
2. Carbon dioxide will be removed more efficiently
3. More blood vessels - an increase in capillaries around the alveoli- more oxygen
4. After a sustained period of regular exercise, the improved efficiency of the lungs will allow better delivery of oxygen to the working muscles,

(therefore the body will be able to cope better during exercise)

Question 21

What does VO2 Max mean?

Answer 21

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

Question 22

Why does your tidal volume increase during exercise

Answer 22

Because the amount of oxygen needed increases and the body produces more carbon dioxide which needs to be removed from the body

Question 23

How can an efficient respiratory system air the cardiovascular system

Answer 23

By providing a constant supply of oxygen for the muscles and removing carbon dioxide

Question 24

Why is an efficient cardio respiratory system vital for health and performance?

Answer 24

Because the harder and longer you exercise for ( intensity and time), the more oxygen is needed for to keep the muscles working and the more carbon dioxide is produced which needs to be removed
