functions of right atrium
Answers
right atrium is one of chambers in our heart. its main function is to receive deoxygenated blood from superior and inferior vena cava then it's sends to right ventricle from where is goes to lungs through pulmonary arteries...
hope it will help u...
The right atrium is the upper right ventricle. It opens in the right ventricle through the tricuspid valve. The right atrium acts as a storage unit for the deoxygenated blood of the body.
The superior vena cava produces oxygen-free blood from parts of the body above the heart, such as the head and arms. The inferior vena cava is the largest vein of the human body. It transports oxygen-free blood from parts of the body below the heart, such as the stomach and legs. The superior vena cava and the inferior vena cava are two large veins that deliver low-oxygen blood to the right atrium.
The superior vena cava produces oxygen-free blood from parts of the body above the heart, such as the head and arms. The inferior vena cava is the largest vein of the human body. It transports oxygen-free blood from parts of the body below the heart, such as the stomach and legs. A coronary sinus is a group of veins that receive oxygen-free blood from the cardiac veins.
When the right atrium is filled with oxygen-free blood, it contracts and opens the tricuspid valve. Oxygen-free blood can flow into the right ventricle through the open valve. Once the right ventricle is full, the tricuspid valve closes to prevent backflow into the right atrium. The right ventricle has an exit vein, the pulmonary artery, which carries oxygen-free blood into the lungs.
