do frogs have systemic circulation
The circulatory system of a human compared to that of a frog is different due to the number of chambers each contains. A frogâs heart has three chambers (two atria, and a single ventricle), whereas a humanâs has four (two atria, and two ventricles).The atrium of a frog receives deoxygenated blood from the blood vessels that drain the various organs of the body.The left atrium receives oxygenated blood from the lungs and skin. Both atria empty into the single ventricle, which is divided into narrow chambers that reduce the mixing of the two bloods.n the systemic circulation, arteries collect the oxygen-rich blood from the heart and transport it to the body tissues. In the process, oxygen from the blood is diffused into the body cells, and carbon dioxide from the cells is diffused in the blood.
