Systemic circulation is the portion of the cardiovascular system which carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.
Arteries always take blood away from the heart, regardless of their oxygenation, and veins always bring blood back. In general, arteries bring oxygenated blood to the tissues; veins bring deoxygenated blood back to the heart. In the case of the pulmonary vessels, however, the oxygenation is reversed: the pulmonary artery takes deoxygenated blood from the heart to the lungs, and oxygenated blood is pumped back through the pulmonary vein to the heart. As blood circulates through the body, oxygen and nutrients diffuse from the blood into cells surrounding the capillaries, and carbon dioxide diffuses into the blood from the capillary cells.
The release of oxygen from red blood cells or erythrocytes is regulated in mammals. It increases with an increase of carbon dioxide in tissues, an increase in temperature, or a decrease in pH. Such characteristics are exhibited by tissues undergoing high metabolism, as they require increased levels of oxygen.
Pulmonary circulation is the portion of the cardiovascular system which carries oxygen-depleted blood away from the heart, to the lungs, and returns oxygenated blood back to the heart.
De-oxygenated blood enters the right atrium of the heart and flows into the right ventricle where it is pumped through the pulmonary arteries to the lungs. Pulmonary veins return the now oxygen-rich blood to the heart, where it enters the left atrium before flowing into the left ventricle. From the left ventricle the oxygen-rich blood is pumped out via the aorta, and on to the rest of the body.
The Coronary circulatory system provides a blood supply to the heart.

The circulatory system has how many main pathways for movement?
The circulatory system is made up of two main pathways. These are the systemic circulation and the pulmonary circulation.
Which organ is bypassed in the special circulation pathways of a fetus?
The liver is partialy bypassed
What are the two major pathways of the vascular system?
The two major pathways of the vascular system are the systemic circulation, which carries oxygenated blood from the heart to the body's tissues and organs, and the pulmonary circulation, which carries deoxygenated blood from the heart to the lungs for oxygenation.
What are the three major branches of the systemic circulation?
The systemic circulation includes three parts. The coronary circulation, the hepaticportal circulation and the renal circulation
The three main pathways through which a blood flows?
the three pathways through wich blood flows are the arteries,veins,and capillaries
What the three types of circulation?
the three types of Blood Circulation are.Portal circulationPulmonary (Lesser) circulationSystemic (Greater) circulation
What are the three pathways, including the alternative, classical, and lectin pathways, that activate the immune system's response to what?
The three pathways that activate the immune system's response are the alternative, classical, and lectin pathways. They work together to recognize and respond to foreign invaders, such as pathogens or damaged cells, in the body.
Are they three clotting pathways?
The coagulation cascade is classically divided into three pathways. The tissue factor (formerly known as the extrinsic) and the contact activation (formerly known as the intrinsic) pathways both activate the final common pathway of factor X, thrombin and fibrin.
How many pathways are there in a parallel circuit witn theree bulbs?
In a parallel circuit with three bulbs, there are three separate pathways for current to flow, one for each bulb. This means that each bulb has its own independent connection to the power source, and if one bulb were to fail, the others would still light up.
Are Renal circulation and portal circulation different and why?
Yes, renal circulation refers to the blood flow through the kidneys, where blood is filtered and waste products are removed. Portal circulation refers to the blood flow from the gastrointestinal tract to the liver before returning to the heart. These circulations are different due to their distinct anatomical pathways and unique functions in the body.
What provides alternate pathways for blood to get to an organ?
Collateral circulation provides alternate pathways for blood to reach an organ if the usual route is blocked or restricted. It helps to ensure that vital organs receive adequate blood supply even if there is an obstruction in a blood vessel.
How many circulation pathways do a fishes have?
every organ of fishes have a pathway of blood , so the pathway of circulation of fishes are depend on how many organ they have because not all the fish have the same structure some of them may have the organ which others dont... hope to help
