Question

during the ejection phase of the cardiac cycle, blood exits the left ventricle through the
multiple choice

aorta
coronary sinus
pulmonary vein
superior vena cava
pulmonary trunk.

Explanation:

During the ejection phase of the cardiac cycle, oxygen - rich blood leaves the left ventricle and enters the aorta to be distributed throughout the body. The coronary sinus is related to the return of de - oxygenated blood from the heart muscle. Pulmonary veins carry oxygenated blood from the lungs to the left atrium. The superior vena cava returns de - oxygenated blood from the upper body to the right atrium. The pulmonary trunk carries de - oxygenated blood from the right ventricle to the lungs.

Answer:

Aorta (assuming the first option is aorta as the text is a bit unclear about option labels but aorta is the correct answer based on knowledge of the cardiac cycle)
