Answer:
The correct option is (D). The value of cardiac output in the case of the human heart is approx. 5 liters in a minute. The multiplication product of heart rate and stroke volume gives the cardiac output.
Explanation:
The blood flow serves as the parameter for the calculation of cardiac output. For the restoration of homeostasis, increase or decrease in the cardiac output leads to the simultaneous increase and decrease in the blood flow and pressure respectively. Also, the reduction of cardiac output and venous return signifies the higher value of the tidal volume. The associated parameters namely stroke volume and heart rate is also affected by certain factors. Some of them includes age, gender, contractility, heart size and duration of contraction.
Besides the flow of blood in the body depends on the oxygen requirement of the target cell.
The stomata open up to absorb the carbon dioxide needed to perform photosynthesis.
Answer:
Cell is the basic unit of life
