Answer:
(C). thermoregulation and hormone transport.
Explanation:
Homeostasis can be defined as a steady state of internal body conditions maintained by living organisms.Cardiovascular system helps the body to maintain homeostasis through thermoregulation and transport of hormones.
Thermoregulation involves regulation of internal body temperature. Cardiovascular system works to transport nutrients, oxygen, and hormones to various tissues and organs through blood.
It helps in heat exchange between internal organs, skin or tissues to maintain internal body temperature. All endocrine glands secrete hormones directly to the blood stream, from where the hormones are transported to different tissues and organs and show their response.
Thus, the correct answer is option (C).
