Question

select all of the following which are functions of the cardiovascular system. maintain homeostasis release of hormones support immune response transport of nutrient

Explanation:

1. Maintain homeostasis: The cardiovascular system helps regulate factors like temperature, pH, and nutrient levels to maintain internal balance (homeostasis).
2. Release of hormones: Endocrine glands release hormones, but the cardiovascular system transports them. However, some cells in the heart (e.g., atrial cells) release hormones like ANP, so this can be considered a function (though hormone release is primary for endocrine system, cardiovascular system has minor hormone - releasing roles too).
3. Support immune response: White blood cells are transported via the cardiovascular system to sites of infection, so it supports the immune response.
4. Transport of nutrient: The cardiovascular system transports nutrients (like glucose, amino acids, etc.) from the digestive system to cells throughout the body.

Answer:

Maintain homeostasis, Support immune response, Transport of nutrient, Release of hormones (Note: While hormone release is not the primary function of the cardiovascular system compared to the endocrine system, the heart does secrete some hormones, so it can be included. If we consider only the major transport - related and homeostatic/immune - supporting functions, the first, third, and fourth are more definitive, but based on the options given, all except maybe none are correct in the context of the cardiovascular system's broader functions including hormone transport and its own hormone secretion).
