Sep 14, 2021 · The ventricles serve as the primary pumping chambers of the heart, propelling blood to the lungs or to the rest of the body. There are two distinct but linked circuits in the human circulation called the pulmonary and systemic circuits.

Apr 13, 2024 · The left side of the heart receives oxygenated blood from the lungs and pumps it to the body. This is a big task, which is why the left ventricle is the largest and strongest heart chamber. The valves between the chambers control the flow of blood and prevent it from flowing backwards.

Aug 28, 2023 · The left ventricle is the main pumping chamber of the left heart, then pumps, sending freshly oxygenated blood to the systemic circulation through the aortic valve. The cycle is then repeated all over again in the next heartbeat.

The right ventricle receives deoxygenated blood from the right atrium, and pumps it through the pulmonary orifice (guarded by the pulmonary valve), into the pulmonary artery. It is triangular in shape, and forms the majority of the anterior border of the heart. The right ventricle can be divided into an inflow and outflow portion, which are separat...
The interventricular septum separates the two ventricles, and is composed of a superior membranous part and an inferior muscularpart. The muscular part forms the majority of the septum and is the same thickness as the left ventricular wall. The membranous part is thinner, and part of the fibrous skeletonof the heart.
The left ventricle receives oxygenated blood from the left atrium, and pumps it through the aortic orifice (guarded by the aortic valve) into the aorta. In the anatomical position, the left ventricle forms the apex of the heart, as well as the left and diaphragmatic borders. Much like the right ventricle, it can be divided into an inflow portion an...

The heart is a hollow, muscular organ that pumps oxygenated blood throughout the body and deoxygenated blood to the lungs. This key circulatory system structure is comprised of four chambers. One chamber on the right receives blood with waste (from the body) and another chamber pumps it out toward the lungs where the waste is exhaled.
The left atrium receives oxygenated blood from pulmonary circulation through the left and right pulmonary veins. Blood passively flows into the atria without passing through valves. The atria relax and dilate (expand) while they fill with blood in a process called atrial diastole.
