Answer 15

Supply blood to kidneys

Question 16

Answer 16

Take blood away from kidneys

Question 17

Lliac arteries

Answer 17

Takes oxy blood to legs

Question 18

Lliac veins

Answer 18

Takes deoxy blood from legs to posterior Vena cava

Question 19

Exhalation process

Answer 19

1. Diaphragm relaxes and moves up, intercoastal muscles collapse
2. Decreased volume of chest cavity
3. Lungs deflate
4. Exhalation
5. Air forced out of alveoli into bronchioles
6. Air moves from bronchioles to bronchi
7. Air moves from bronchi into trachea (air cooled)
8. Air travels past larynx, epiglottis and pharynx
9. Air forces out of body

Question 20

Inhalation process

Answer 20

1. Diaphragm contracts and moves down, intercoastal muscles expand
2. Increase in volume of chest cavity
3. Lungs expand creating vacuum effect
4. Inhalation
5. Air moistened and warmed as travels through nose
6. Air moves past epiglottis, larynx and pharynx
7. Air filtered, moistened and warmed as passes down trachea
8. Air travels from trachea to bronchi
9. Air into bronchioles
10. Air reaches alveoli

Question 21

What is partial pressure

Answer 21

Concentration of gas (mm Hg)

Question 22

How is O2 transported

Answer 22

98% of O2 is bonded to haemoglobin in the red blood cells

1.5% dissolved into plasma

Question 23

What is a high PP

Answer 23

Above 40mm Hg

Question 24

The oxygen dissociation curve shows that…?

Answer 24

The more you exercise the PP of O2 is your cells is low, and the saturation of the haemoglobin is low, it is uploading more oxygen to the active cells

Question 25

What are the three ways CO2 is transported from the body to the lungs?

Answer 25

60% bicarbonate
30% carbaminohaemoglobin
10% dissolved in plasma

Question 26

How is bicarbonate formed?

Answer 26

When C02 (waste from cellular respiration) combines w H2O

Question 27

How is carbaminohaemoglobin formed?

Answer 27

When CO2 combines w unoxygenated haemoglobin

Question 28

Formula for buffer system:

Answer 28

CO2 + H2O H2CO3 HCO3- + H+

Question 29

Buffer system: what why how

Answer 29

• pH of blood affects other variables in the body, is important it stays at right pH level
• if the pH drops (acidic) system goes LR
• is part of homeostasis
