Question

What type of circulatory system does a human have?

Answer 1

Circulatory system:

1. Humans have a closed circulatory system.
2. The circulatory system is one of the transport systems in which nutrients, gases, and other molecules are transported within the animal's body.

There are two main types of the circulatory system.

1. An open circulatory system and a closed circulatory system.
2. In the open circulatory system, blood directly infiltrates cells, in contrast to the closed circulatory system, where blood flows through blood vessels.
3. There is no difference between blood and interstitial fluid, as blood is not limited to the blood vessels of the open circulatory system. In contrast, blood and interstitial fluid do not mix in a closed circulatory system.
4. The closed circulatory system is made up of the heart, which pumps blood into blood vessels and reaches tissues and organs. Gas exchange in the bloodstream occurs between small blood vessels (capillaries) and tissues.
