The heart is two side-by-side pumps, each serving a separate blood circuit:

- The blood vessels that carry blood to and from the lungs form the pulmonary circuit, which serves gas exchange.

- The blood vessels that carry the functional blood supply to and from all body tissues constitute the systematic circuit.

Pulmonary circuit - the right side of the heart is the pulmonary circuit pump. Blood returning from the body is relatively oxygen-poor and carbon dioxide-rich. It enters the right atrium and passes into the right ventricle, which pumps it to the lungs via the pulmonary trunk. In the lungs, the blood unloads carbon dioxide and picks up oxygen. The fresh oxygenated blood is carried by the pulmonary veins back to the left side of the heart (left atrium). NOTICE how unique this circulation is. Typically, we think of veins as vessels that carry blood that is relatively oxygen-poor to the heart and arteries as transporters of oxygen-rich blood from the heart to the rest of the body. Exactly the opposite condition exists in the pulmonary circuit.

Systematic circuit - the left side of the heart is the systematic circuit pump. Freshly oxygenated blood leaving the lungs is returned to the left atrium and passes into the left ventricle which pumps it into the aorta. From there the blood is transported via smaller systemic arteries to the body tissues, where gases and nutrients are exchanged across the capillary walls. Then the blood once again loaded with carbon dioxide and depleted of oxygen, returns through the systemic veins to the right side of the heart, where it enters the right atrium through the superior and inferior venae cavae.

What are systemic and pulmonary circulation?

Systemic circulation is the flow of blood from the heart to all parts of the body and back to the heart, while pulmonary circulation is the flow of blood between the heart and the lungs. Systemic circulation delivers oxygen and nutrients to the body's tissues, while pulmonary circulation is responsible for oxygenating the blood and removing carbon dioxide.


What is the systemic circulation from pulmonary circulation?

Systemic circulation is the part of the cardiovascular system that carries oxygen-rich blood from the heart to the body and returns oxygen-depleted blood back to the heart. Pulmonary circulation, on the other hand, is the circulation of blood between the heart and lungs, where blood picks up oxygen and releases carbon dioxide. Systemic circulation follows pulmonary circulation in the blood flow cycle.


Is the blood that your heart pumps to your stomach part of the pulmonary circulation loop and why?

No, the blood that your heart pumps to your stomach is not part of the pulmonary circulation loop; it is part of the systemic loop. The pulmonary circulatory loop only travels to the heart and lungs in a circuit, with no other organs included.


What is the difference between pulmonary circulation coronary circulation and systematic circulation?

the circulation is divided into 2 circulations 1st is pulmonary circulation in which what happens is that when the pulmonary artery caring impure blood to the lungs for purification and the pure blood (oxygenated) in brought back from lungs to heart through pumonary vien, this is pulmonary circulation 2nd systematic circulation in this what happens is that the pure blood from the left ventricle is forced to all other part of the body through aorta to all the cells and tissues, after the diffusion in which stuffs are interchanged( carbon dioxide and glucose and oxygen) it is brought back to the heart through inferior or superior vena cava, this is systemic circulation Finally, the coronary circulation is the circulation of blood that feeds the heart itself, since it does not receive any oxygen from the systemic or pulmonary circulations.


What are the four main types of blood circulation?

there are both single and double circulatory systems.fish have single ones, and birds have double.in double circulatory system the blood travels trough the heart twice in it's way around the body, while in the single it only goes through the heart once.Answer by FutureLPGAgolferThe answer came from my homework and I got it right, it's the Open system and the Closed system.explain how number of exercises affects the breathing rate?

What are systemic and pulmonary circulation?

Systemic circulation is the flow of blood from the heart to all parts of the body and back to the heart, while pulmonary circulation is the flow of blood between the heart and the lungs. Systemic circulation delivers oxygen and nutrients to the body's tissues, while pulmonary circulation is responsible for oxygenating the blood and removing carbon dioxide.


What is the structural difference between pulmonary vessel walls and systemic vessel walls?

The role of the pulmonary circulation is to take blood that is poor in oxygen and load it up with oxygen. It also takes the carbon dioxide content of blood and gets rid of it, that is you exhale it. One role of the systemic cirulation to deliver oxygen rich blood to where it is needed. That is to say that cells need oxygen to do their work, the brain to think and the muscles to contract. They get their oxygen from the systemic circulation. But blood in the systemic circulation got its oxygen from being in the pulmonary circulation.


What part of pulmonary circulation is systemic part of the path of blood through the heart is pulmonary?

The systemic circulation is the part of the circulatory system that carries oxygenated blood away from the heart to the body and returns deoxygenated blood back to the heart. In contrast, the pulmonary circulation is the part of the circulatory system that carries deoxygenated blood from the heart to the lungs for oxygenation and returns oxygenated blood back to the heart.


Differentiate clearly between the roles of the pulmonary and systemic circulation?

pulumonary serculation is cerculated in the lung systemic serculation is all of ours body system


What are the differences and similarities between the pulmonary and systemic circulations?

Pulmonary Circulation carries deoxygenated blood to the lungs to receive oxygen, while the Systemic Circulation carries the oxygenated blood throughout the body so the oxygen can be used, returning to the Pulmonary Circulation as deoxygenated blood.


What type of blood circulation is between the heart and the rest of the body?

The systemic circulation carries blood between the heart and the rest of the body. In contrast, the pulmonary circulation brings blood between the heart and the lungs.


What are the 3 primary cycles of blood in the human body?

The three primary cycles of blood in the human body are the pulmonary circulation, systemic circulation, and the portal circulation. Pulmonary circulation involves the flow of blood between the heart and the lungs, systemic circulation circulates blood throughout the body, while portal circulation carries blood from the digestive organs to the liver.


What condition is indicated by the structural difference between systemic and pulmonary arteries?

What are the differences between the systemic and pulmonary circulatory systems?

the heart has two systems, the pulmonary and the systemic system.the pulmonary is responsible for getting carbonated blood (blue) to the lungs to get loaded with nutrients and oxygen (see cellular respiration) and to take oxygen rich blood back to the heart. While the systemic system is responsible for taking oxygenated blood (red) from the heart to the rest of the body to diffuse the ATP (ATP = oxygen + nutrients from food. ATP is energy.) Then the carbonated blood (carbonated) returns to the heart to be sent back to the lungs.(pulmonary system)
