Closed Circulatory System Definition

Blood flows within closed arteries in this sort of circulatory system, therefore blood is distinguished from interstitial fluid.

The circulatory system is one of the transport systems that transports nutrients, gases, and other substances throughout an animal’s body.

The open circulatory system and the closed circulatory system are the two main types of circulatory systems.

The blood bathes the cells directly in an open circulatory system, but in a closed circulatory system, the blood flows through vessels.

Blood and interstitial fluid have no distinction in an open circulatory system since blood is not restricted to arteries.

In a closed circulatory system, however, blood and interstitial fluid do not interact.

The heart pumps blood into the arteries so that it may reach the tissues and organs in a closed circulatory system.

Gases are exchanged between smaller vessels (capillaries) and tissues in the circulation.

Annelids and vertebrates are examples of creatures with a closed circulatory system (including humans).

Humans have a cardiovascular system, which consists of the heart and blood arteries that circulate blood throughout the body, as well as a lymphatic system, which circulates lymph.
