it is carried to the liver to filter harmful substances,
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.
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.
The liver cleans out toxins from your blood, such as alcohol, drugs, and other things. It keeps all the gunk that doesn't need to be in your blood out (drugs and some other things). It doesn't filter your blood. That is your kidney's job.
Blood returning from the body systemic circulation first enters which chamber of the heart?
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.
As the Circulatory System is a closed system, it has no beginning or end. Therefore the blood is in continuous circulation.
Blood returning from systemic circulation enters the heart at the right atrium. Blood from the pulmonary circulation enters the left atrium.

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.
