Blood is carried to the liver before entering systemic circulation primarily through the hepatic portal vein. This process allows the liver to filter and process nutrients, toxins, and other substances absorbed from the digestive tract. By doing so, the liver can metabolize nutrients, detoxify harmful substances, and regulate blood glucose levels, ensuring that only properly processed blood enters the systemic circulation. This is crucial for maintaining overall metabolic balance and health.
Blood 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.
As the Circulatory System is a closed system, it has no beginning or end. Therefore the blood is in continuous circulation.
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.
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.
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.

Systemic circulation circulates through body tissues but not the lungs.
Systemic circulation circulates through body tissues but not the lungs.
Coronary circulation is a sub-set of systemic circulation, it just supplies the heart. Pulmonary circulation is mecanically the same as systemic, but the blood enters as deoxigenated, and the pressures are much lower.
Blood enters the heart from the systemic circulation in the right atrium, and then moves to the right ventricle. From there, blood is pumped into the pulmonary circulation. When the blood returns from the lungs, it enters the left atrium, then left ventricle, then is pumped to body tissues via the systemic circulation.
Blood returning from systemic circulation enters the heart at the right atrium. Blood from the pulmonary circulation enters the left atrium.

Kidneys receive blood from systemic circulation via the RENAL ARTERIES, the blood flows through them and re-enters systemic circulation via the RENAL VEINS
