- You can think of both atria (the plural form of “atrium”) as reservoirs. While your right atrium holds oxygen-poor blood, your left atrium holds oxygen-rich blood. Your left atrium then sends this blood through your mitral valve and into your left ventricle.

Apr 13, 2024 · The short answer is that deoxygenated blood from the body enters the right atrium of the heart and the right ventricle pumps it to the lungs. The oxygenated blood returns to the heart, entering the left atrium, while the left ventricle pumps it to the body.

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...

Your heart chambers work together to pump oxygen-poor blood to your lungs and oxygen-rich blood to your entire body. What are the heart chambers? Your heart chambers are four hollow spaces within your heart. There are two atria (upper chambers) called your right atrium and left atrium.
Aug 17, 2023 · Each pump contains an upper chamber that functions as a receptacle for incoming blood, called the atrium, and a lower chamber that is responsible for pushing blood out of the heart called the ventricle.

Nov 3, 2024 · 1. Blood Enters the Right Atrium. The journey of blood flow through the heart begins as deoxygenated blood, rich in carbon dioxide, enters the right atrium. This blood arrives from the upper part of the body via the superior vena cava and from the lower part of the body via the inferior vena cava. 2.
Mar 24, 2022 · Oxygen-poor blood from the body enters your heart through two large veins called the superior and inferior vena cava. The blood enters the heart's right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs.
Figure \(\PageIndex{4}\) shows how blood circulates through the chambers of the heart. The right atrium collects blood from two large veins, the superior vena cava (from the upper body) and the inferior vena cava (from the lower body). The blood that collects in the right atrium is pumped through the tricuspid valve into the right ventricle.
