From the left ventricle.
In the pulmonary circulation, deoxygenated blood leaves the right section of the heart through the pulmonary artery, enters the lungs and oxygenated blood comes through the pulmonary veins. The blood then moves to the left atrium of the heart.
There is more blood in the systemic circuit than the pulmonary circuit. Even the arterial portion of the systemic circuit is larger than the entire pulmonary circuit, because the pulmonary circuit only delivers blood to the lungs, and the systemic circuit supplies the rest of the body.
The left ventricle pumps blood to the systemic loop.
Left Ventricle, because it pumps blood to the systemic circuit whereas the right ventricle pumps blood to the lungs.
The aorta receives blood from the Aortic Valve. The Aortic Valve gets blood from the left ventricle.
Blood returning from the body systemic circulation first enters which chamber of the heart?
In the pulmonary circulation, deoxygenated blood leaves the right section of the heart through the pulmonary artery, enters the lungs and oxygenated blood comes through the pulmonary veins. The blood then moves to the left atrium of the heart.

Deoxiginated blood returning to the heart from the systemic circuit first enters the right atrium. Oxigenated blood going away from the heart goes through the pulmonary veins, enters the left atrium, goes through the left ventrical, and exits through the aorta. Just don't forget the three major parts of the circulatory system (( the lungs (pulmonary), the heart (coronary), and the rest of the system (systemic))) and keep in mind of their differences. Keep on at it and study hard!
The left ventricle pumps blood to the systemic loop.
Left Ventricle, because it pumps blood to the systemic circuit whereas the right ventricle pumps blood to the lungs.
The blood pressure is the highest in the arteries. It will decrease continuously as it flows through the systemic circuit.
In the systemic circuit, oxygenated blood is distributed to body tissues.The systemic circuit also distributes nutrients to the body tissues and removes waste.
The pulmonary circuit is blood flow movements from the pulmonary trunk to the left atrium...while the systemic circuit is a continuation from the left atrium all the way to the right atrium.......... Disclaimer [research for detailed blood movements in pulmonary circuit and systemic circuit if this isn't enough].
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.
The aorta receives blood from the Aortic Valve. The Aortic Valve gets blood from the left ventricle.
