TOPIC 18 DAY 1 FACTORS AFFECTING BLOOD FLOW

An individual has a genetic disorder leading to abnormally high blood viscosity, what impact would this have on blood flow within the circulatory system?

• Blood flow would increase due to decreased resistance.

• Blood flow would remain constant regardless of viscosity.

• Blood flow would decrease due to increased resistance.

• Blood flow would reverse direction within the vessels.

A person is experiencing hypertension, a condition characterized by consistently elevated (high) blood pressure levels.

How would this condition affect blood flow in the body?

• Blood flow would decrease due to relaxed blood vessel walls.

• Blood flow would increase due to widened blood vessels.

• Blood flow would decrease due to increased resistance in blood vessels.

• Blood flow would remain unaffected by changes in blood pressure.

Imagine a scenario where an individual is diagnosed with atherosclerosis, a condition characterized by the narrowing of arteries due to plaque buildup.

Considering this, how would you expect blood flow to be affected?

• Blood flow would increase due to the widening of arteries.

• Blood flow would remain unaffected by the condition.

• Blood flow would decrease due to increased resistance from narrowed arteries.

• Blood flow would fluctuate depending on the individual's diet.

Consider a marathon runner who trains her body consistently to perform during aerobic conditions.

What changes would you expect in her circulatory system to support increased blood flow during her long-distance runs?

• Decreased cardiac output to conserve energy during exercise.

• Increased blood flow to skeletal muscles to meet oxygen demand.

• Constricted blood vessels to minimize blood loss during exercise.

• Decreased blood viscosity to facilitate smoother blood flow.

An individual develops a viral infection that causes inflammation and constriction of blood vessels.

How would this affect blood flow within the circulatory system?

• Blood flow would decrease due to widened blood vessels.

• Blood flow would increase due to relaxed blood vessel walls.

• Blood flow would decrease due to increased resistance in blood vessels.

• Blood flow would remain unaffected by changes in vessel diameter.

An individual is involved in a crash accident where he suffered a severe injury leading to a great loss of blood volume.

How does this acute loss of blood volume impact blood flow within the circulatory system?

• Blood flow increases due to compensatory mechanisms.

• Blood flow decreases due to reduced blood volume.

• Blood flow remains constant regardless of changes in blood volume.

• Blood flow becomes erratic due to trauma-induced vessel damage.
