Iwill give brainliest ! describe how blood flows through the circulatory system in each of these circuits: the pulmonary circuit: the systemic circuit:

The pulmonary circuit: The oxygenated blood then leave the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. This blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. From the left ventricle, the blood passed through the aortic valve to the aorta.
The systemic circuit: systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.

Try and make the question more clear : )

This type of galaxy is an approximately ellipsoidal shape and a smooth, nearly featureless image. they are the largest single star systems, in the universe and are built by the collisions of many smaller galaxies.
