Circulatory system
Circulatory system
The atrium belongs to the cardiovascular system, which is responsible for circulating blood throughout the body. The atrium is a chamber within the heart that receives blood from the body and sends it to the ventricles for pumping to the lungs or rest of the body.
Circulatory system
because the ventricle is carrying the blood toward the heartBecause the ventricle has to pump blood all over the body whereas the atrium only pumps it to the ventricle.
Same as your and my heart, they gather blood from the veins, put it into the frogs single ventricle, and pump it out to the lungs and body.
right atrium
The coronary sinus empties into the right atrium of the heart. It serves as a drainage system for deoxygenated blood from the myocardium.
The vascular circuit that connects the right atrium to the left atrium is the pulmonary circulation.
From the venous system, blood enters the right atrium, then goes to the right ventricle, then in to the pulmonary system, then to left atrium, then left ventricle then back out to the body.
The three chambers of a frog's heart are called the right atrium, left atrium, and ventricle. The right atrium receives deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs. Both atria then pump blood into the single ventricle, which distributes it to the rest of the body and lungs. This structure allows for some mixing of oxygenated and deoxygenated blood, which is typical for amphibians.
