iVinArrow [24]

Answer:

The structure that prevents backflow of blood into the left atrium is the mitral valve.

The vessel that carries oxygen-rich blood to tissues is the aorta.

The capillaries receiving blood flow from the left side of the heart are the Systemic capillaries.

The structure that is located anatomically between the aorta and the left ventricle is the Aortic semilunar valve.

Explanation:

The left atrium receives oxygen-rich blood from the pulmonary vein and passes it to the left ventricle. The back-flow of blood from the left ventricle into the left atrium is prevented by mitral which is a bicuspid valve. The vessel that carries oxygen-rich blood to tissues is the aorta.

Aorta receives oxygen-rich blood from the left ventricle and pumps it into its branches to deliver the blood to the body tissues. Systemic capillaries are the blood vessels that obtain the oxygen-rich blood from the left ventricle through the aorta. Systemic capillaries serve as the site for the exchange of gases and nutrients.

The aortic semilunar valve is located Aortic semilunar valve is the half-moon shape valve present between the left ventricle and aorta to prevent the black flow of blood to the left ventricle.
