Heart Adaptations

Question 1

What are the 2 general adaptations of the heart? (2)

Answer 1

1. Septum - cardiac muscle wall separating the two sides of the heart (and therefore the types of blood)
2. Apex - ventricle contraction occurs from the apex upwards, ensuring that blood is pumped up and out of the arteries.

Question 2

What are the adaptations of the right ventricle?

Answer 2

Thinner cardiac muscle wall b/c the dexoxy blood is only travelling a short distance.

Question 3

What are the adaptations of the left ventricle?

Answer 3

Thicker cardiac muscle wall allows oxygenated blood to be pumped at a HP to the rest of the body to meet oxygen demand for cellular aerobic respiration.

Question 4

What are the functions and adaptations of the aorta?

Answer 4

Pumps HP oxygen-rich blood from the left side of the heart to tissues with a high oxygen demand, undergoing aerobic respiration.
