A

Heart is larger, more blood and healthier blood vessels means heart does not need to work so hard to deliver O2 when at rest.

59
Q

What happens to a spirometer trace reading if a person starts to exercise vigorously?

A

The readings become larger (deeper breaths) and more frequent (quicker breaths)

60
Q

What is the structure and function (role) of an artery?

A

Carry blood away from the heart
Small lumen (space for blood flow), therefore high blood pressure
Thick, muscular walls

61
Q

Why does tidal volume and breathing rate increase when we start to exercise?

A

Due to higher demand of oxygen in working muscles, and more waste products being produced breathing must deepen and quicken to meet the demand.

70
Q

What are the immediate effects of exercise on the respiratory system?

A

Tidal volume increases (breathing deepens)

Oxygen debt occurs, if exercise is anaerobic

71
Q

What is the role of the respiratory system?

A

Inhale and exhale air (breathing) to absorb oxygen and remove carbon dioxide (gas exchange)

72
Q

What is cardiac hypertrophy?

A

Folded shape gives large surface area

74
Q

What is the structure and function (role) of a vein?

A 
Hypertension = high blood pressure (above 140/90mmHg)
Hypotension = low blood pressure (below 90/60mmHg)
76
Q

Explain the process of exhaling.

A

Diaphragm relaxes, squeezing the chest cavity and lungs. This pushes air out of the lungs.

77
Q

List the factors that affect blood pressure

A

Age - increases with age
Stress - increased stress increases BP
Diet - poor diet increases BP

A

Vasodilation - widening of blood vessels in areas of the body that need blood the most eg working muscles when exercising.
Vasoconstriction - Narrowing of blood vessels

79
Q

What is gas exchange? Where does it occur?

A

Diffusing oxygen into the blood.
Removing carbon dioxide out of the blood.
In the alveoli of the lungs.

80
Q

Explain the flow of blood around the heart, lungs and body (systemic and pulmonary circulation)

A

Blood flows from heart to lungs to collect oxygen, then back to the heart (pulmonary circuit)
Blood then flows to the body, delivers the oxygen and returns back to the heart (systemic circulation)
