Question

BlackTom AI · Accepted Answer

The question asks about the primary function of the cardiovascular system and presents four options.
Option 1: 'pumps and transports blood' is correct because the cardiovascular system's central role is to pump blood via the heart and to transport it throughout the body, delivering oxygen and nutrients while removing wastes.
Option 2: 'responds to internal and external stimuli' is not its defining function. While the cardiovascular system can respond to stimuli (like changes in blood pressure or sympathetic activation), this describes a broader homeostatic response that involves multiple systems; it is not the core task of pumping and circulating blood.
Option 3: 'secretes hormones' is inaccurate for the cardiovascular system. Hormone production is primarily the domain of glands in the endocrine system; the cardiovascular system may carry hormones in the blood, but it does not secrete them.
Option 4: 'eliminates nitrogenous wastes' is incorrect. Waste elimination is mainly the job of the excretory systems (kidneys, liver through detoxification), not the cardiovascular system itself.
In summary, option 1 accurately captures the essential function of pumping and transporting blood, while the other options describe roles that belong to other physiological systems or to auxiliary processes rather than the primary function of the cardiovascular system.
