ReneBlood is carried from the liver through the hepatic vein before it enters systemic circulation to allow processing and metabolism of nutrients, drugs, and toxins in the liver tissue. This ensures that substances have been properly detoxified or modified by the liver before they are distributed throughout the body.

Where does blood in systemic circulation go after it leaves the heart?
As the Circulatory System is a closed system, it has no beginning or end. Therefore the blood is in continuous circulation.
What is the difference between first pass and phase one of drug metabolism?
First pass metabolism refers to the metabolism of a drug that occurs in the liver after it is absorbed from the gastrointestinal tract, before it enters systemic circulation. Phase 1 metabolism is the initial biotransformation of a drug, primarily carried out by enzymes such as cytochrome P450, to make the drug more polar and easier to eliminate from the body.
Why are atria called receiving chambers?
Atria are called receiving chambers because they receive blood that is returning to the heart from the body or lungs. They then contract to pump this blood into the ventricles for further circulation.
What is blood flow?
Blood enters the right atrium (RA) from the 2 great veins the Superior vena cavae and Inferior vena cavae (SVC and IVC).It then enters the right ventricle (RV) to be pumped at low pressure through the lungs.Oxygenated blood from the lungs returns to the left atrium (LA) and is pumped by the lef ventricle (LV) at hogh pressure through the various components of the systemic cirulation before returning again to the heart.
