The human cardiovascular system can be divided into two circuits: the circuit transports blood between the heart and lungs and the circuit transports blood between the heart and the rest of the body.

The human cardiovascular system can be divided into two circuits: the pulmonary circuit transports blood between the heart and lungs and the systemic circuit transports blood between the heart and the rest of the body.

The pulmonary circuit has a function to transport deoxygenated blood to the lungs (to absorb O2 and release CO2 )and the oxygenated blood to the heart. Systemic circuit sends oxygenated blood out to cells and returns deoxygenated blood to the heart.

Answer with Explanation:

The cardiovascular system or circulatory system has following two circuits:

Pulmonary system: Moves the blood flow to the lungs.Systemic system: Responsible for the blood flow for the rest of the body.

De-oxygenated blood begins from the right chamber of the heart into the right atrium and moves down into the right ventricle, and then is elevated into the pulmonary arteries to the pulmonary capillaries where it gets cleared of carbon dioxide and accumulates oxygen. Oxygenated blood then passes in pulmonary veins to the left chamber of the heart into the left atrium, flowing into the left ventricle, and then is pulled through systemic arteries to the systemic (body) capillaries, where it supplies oxygen to the tissue cells and accumulates up CO2. De-oxygenated blood then rotates via veins to the right chamber of the heart.

Interacting group of various species in a common location. for example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.

Because the carnivores keep the herbivore population in check
