Vedclass · Answer

(D) Cardiac output is defined as the volume of blood pumped by each ventricle per minute. It is calculated as the product of stroke volume (approximately $70 \, ml$) and heart rate (approximately $72 \, 	ext{beats/min}$), which equals approximately $5040 \, ml$ or $5 \, L$ per minute. The body has the ability to alter the cardiac output through the autonomic nervous system and hormonal regulation to meet metabolic demands. Therefore, the statement that the body has no ability to alter cardiac output is incorrect.
