Answer:
thermoregulation and hormone transport
Explanation:
Homeostasis is the state of body in which body undergoes several chemical or physical changes to maintain the internal changes affected by external factors.
All systems in the body undergo different processes to maintain homeostasis and so Cardiovascular system maintain homeostasis through thermoregulation and hormone transport.
Cardiovascular system undergoes thermoregulation, in which heat is exchanged between the internal body organs, tissues and skin to maintain internal body temperature affected external thermal loads.
Cardiovascular system are responsible for blood circulation throughout the body and the blood transport hormones to different body organs or tissues. Hormones are chemical messenger that regulate behavior of different organs. All the endocrine glands secret hormones and release them into blood and then blood circulation transport them to suitable tissue for proper functioning.
Hence, the correct option is thermoregulation and hormone transport.
