Blood then flows from both upper atrium s left atrium and right atrium into the two lower chambers left and right ventricles which then expand. Below the right atrium is the right ventricle.
The pump for the pulmonary circuit which circulates blood through the lungs is the right ventricle the left ventricle is the pump for the systemic circuit which provides the blood supply for the tissue cells of the body.
Path of blood through the circulatory system. When a heart contracts and forces blood into the blood vessels there is a certain path that the blood follows through the human body. Structures of the circulatory system 1. The right atrium is the first chamber of the heart that blood flows through.
The right atrium receives deoxygenated blood through the superior and inferior vena cavas from the body and pumps it to the right ventricle through the tricuspid valve which opens to allow the blood flow through and closes to prevent blood backing up the atrium. The blood moves through pulmonary circulation and then continues on through systemic circulation. The journey that follows the path of blood through our heart and body begins with.
Pulmonary and systemic are the two circuits in the two circuit system of higher animals with closed circulatory systems. The blood vessels of the body are functionally divided into two distinctive circuits. The path of blood through the circulatory system blood circulation begins when the heart relaxes between heart beats.
Pulmonary circuit and systemic circuit. Path of blood through the heart the circulatory system also called the cardiovascular system is responsible for distributing nutrients and oxygen to different parts of the body with the heart working as the pump.
