which of the following statements about heart rate is false:
maximum heart rate can be estimated using a persons age.
the heart rate is the number of times the heart beats per minute.
there is a direct relationship between heart rate and intensity of work.

hematocrit is the percentage of the blood that is made up of:
plasma
red blood cells
white blood cells
red blood cells and plasma

Explanation:

For the first - blank question, the amount of blood pumped out of the left ventricle with each heartbeat is stroke - volume. For Question 32, maximum heart rate can be estimated as 220 minus age, heart rate is beats per minute, there is a direct work - heart rate relationship, and during intense exercise, heart rate can reach 220 bpm or higher, so all statements are true. For Question 33, hematocrit is the percentage of blood made up of red blood cells.

Answer:

The amount of blood that is pumped out of the left ventricle with each heartbeat is known as stroke - volume.
Question 32: None of the above (as all statements are true).
Question 33: red blood cells
