Answer 1

1.Answer is option F (right atrium)

right atrium receives blood from coronary sinus.

In systemic circuit there will be distribution of blood from heart to different parts of the body.

Right atrium receives deoxygenated blood which is rich in Carbon dioxide from Coronary sinus as well as also from superior and inferior Vena Cava.

Coronary sinus is a collection of veins which are joined together to form a large vessel,which gives deoxygenated blood to right atrium.

2.Answer is option D ( right ventricle)

pulmonary artery receives blood from right ventricle.

Pulmonary trunk is a major vessel originating from right ventricle. It gets divided into right and left pulmonary arteries which gives blood directly to lungs. This pulmonary trunk receives blood directly from right ventricle.

Pulmonary artery receives deoxygenated blood and delivers it to lungs for oxygenation.

3.Answer is option B (aorta)

Aorta passes blood from heart to rest of the body.

Aorta gets stretched across the back of the heart and pumps blood above and below the heart to both upper and lower parts of the body.

Aorta is a large artery that ascend s from heart,makes an arch and then descends vertically passing behind the heart and then down through the abdomen.
