Explanation:
The main tissue in the circulatory system :
Cardiovascular tissue has an important role in circulating blood for the migrate of oxygen, nutrients, blood cells, carbon dioxide, and hormones, to maintain the homeostasis in the human body.
The circulatory system provides the functional blood supply to all body tissue. It carries oxygen and nutrients to the cells and picks up carbon dioxide and waste products in body.
The circulatory system or cardiovascular system pumps blood from the heart to the lungs to get oxygen. The heart sends oxygenated blood through arteries to the rest of the whole body. The blood veins carry oxygen poor blood back to the heart to start the circulation process over.
The four important functions are,
- To transport the nutrients, gases and waste products around the body.
- To protect the human body from infection and blood loss.
- To help the body maintain a constant body temperature is called thermoregulation
- To help maintain fluid balance within the body.
