  2. Pulmonary circulation - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_circulation

    The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs. In the lungs the blood is oxygenated and returned to the left atrium to complete the circuit. [1]

  3. Atrium (heart) - Wikipedia

    en.wikipedia.org/wiki/Atrium_(heart)

    There are two atria in the human heart – the left atrium receives blood from the pulmonary circulation, and the right atrium receives blood from the venae cavae of the systemic circulation. During the cardiac cycle, the atria receive blood while relaxed in diastole, then contract in systole to move blood to the ventricles. Each atrium is ...

  4. Cardiac shunt - Wikipedia

    en.wikipedia.org/wiki/Cardiac_shunt

    Blood enters the upper right atrium, is pumped down to the right ventricle and from there to the lungs via the pulmonary artery. [3] Blood going to the lungs is called the pulmonary circulation. [4] When the blood returns to the heart from the lungs via the pulmonary vein, it goes to the left side of the heart, entering the upper left atrium.

  5. Circulatory system - Wikipedia

    en.wikipedia.org/wiki/Circulatory_system

    The right heart pumps deoxygenated blood to the lungs in the pulmonary circulation. In the human heart there is one atrium and one ventricle for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: left atrium, left ventricle, right atrium and right ventricle. The right atrium is the upper ...

  6. Cardiac cycle - Wikipedia

    en.wikipedia.org/wiki/Cardiac_cycle

    Circulation is split into pulmonary circulation—during which the right ventricle pumps oxygen-depleted blood to the lungs through the pulmonary trunk and arteries; or the systemic circulation—in which the left ventricle pumps/ejects newly oxygenated blood throughout the body via the aorta and all other arteries. [1] [2]

  7. Inferior vena cava - Wikipedia

    en.wikipedia.org/wiki/Inferior_vena_cava

    The inferior vena cava is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart.It is formed by the joining of the right and the left common iliac veins, usually at the level of the fifth lumbar vertebra.

  8. Cardiac physiology - Wikipedia

    en.wikipedia.org/wiki/Cardiac_physiology

    The function of the right heart, is to collect de-oxygenated blood, in the right atrium, from the body via the superior vena cava, inferior vena cava and from the coronary sinus and pump it, through the tricuspid valve, via the right ventricle, through the semilunar pulmonary valve and into the pulmonary artery in the pulmonary circulation ...

  9. Right atrial pressure - Wikipedia

    en.wikipedia.org/wiki/Right_atrial_pressure

    Right atrial pressure (RAP) is the blood pressure in the right atrium of the heart. RAP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood into the arterial system.
