Question

The correct match of blood vessel, its connection and O₂ content is ____________.

Options

• Coronary sinus – Right atrium – Low O₂

• Superior venacave – Left atrium – Low O₂

• Systemic aorta – Right ventricle – High O₂

• A-coronary artery – b-Left ventricle – c-Low O₂

Answer 1

The correct match of blood vessel, its connection and O₂ content is Coronary sinus – Right atrium – Low O₂.

Explanation:

The superior venacave receives polluted blood from the body's front and feeds it into the right atrium. The left ventricle gives rise to the systemic aorta, which supplies pure blood to all areas of the body. The dorsal aorta gives rise to the coronary artery, which feeds blood to the heart muscles.
