Starlings Law and Cardiovascular Drift

Question 1

What is starlings law?

Answer 1

Where increased venous return leads to an increase in stroke volume

Question 2

What are the stages of starlings law?

Answer 2

1. Increased venous return
2. Greater diastolic filling of the heart
3. Cardiac muscle stretched
4. Greater force of contraction
5. Increased ejection fraction

Question 3

What is cardiovascular drift?

Answer 3

Where a decrease in venous return leads to an increase in heart rate

Question 4

When does cardiovascular drift occur?

Answer 4

Due to prolonged exercise in warm environments

Question 5

What are the stages of cardiovascular drift?

Answer 5

1. Sweating leads to a drop in blood volume
2. Venous return decreases
3. Decrease in stroke volume
4. Heart rate increases to compensate for
