Cardiovascular

Question 1

What is heart rate?

Answer 1

The number of time your heart beats per minute

Question 2

What is stroke volume?

Answer 2

The amount of blood each ventricle pumps with each contraction

Question 3

What is cardiac output?

Answer 3

Volume of blood pumped by a ventricle per minute

Question 4

Cardiac output formula?

Answer 4

Cardiac output = heart rate X stroke volume

Question 5

Short term effects of exercise on cardiovascular system?

Answer 5

Heart rate, body temperature, cardiac output both increase.
Blood pressure increases to send oxygenated blood quickly to working muscles.

Question 6

Long term effects of exercise on cardiovascular system?

Answer 6

Resting heart rate and blood pressure will drop as the system becomes more efficient
Stroke volume + cardiac output increase as heart will be able to contract with more power

Question 7

What is blood shunting?

Answer 7

In exercise, cardiovascular system redistributes blood so more goes to working muscles and less goes to other body organs (the digestive system). This redirection of blood flow is caused by a mechanism (or process) called the vascular shunt mechanism.
