a.
To determine:
If both stroke volume and heart rate increases, cardiac output (a) stays the same, (b) increases, or (c) decreases and to determine whether the relationship between these two variables and cardiac output is inverse or direct.
Concept introduction:
The amount of blood, which is pumped by either ventricle in one minute, is known as “cardiac output” (
To determine:
When both stroke volume and heart rate increases, cardiac output stays the same or not.
b.
To determine:
When both stroke volume and heart rate increases, cardiac output increases or not.
c.
To determine:
When both stroke volume and heart rate increases, cardiac output decreases or not.
