Question

What is the name of the blood vessel that carries deoxygenated blood from the body to the heart in a frog?

Options

• Aorta

• Pulmonary artery

• Pulmonary vein

• Vena cava

Answer 1

Vena cava

Explanation:

Frogs have a three-chambered heart (2 atria + 1 ventricle). The vena cava is the large vein that collects deoxygenated blood from the body and delivers it to the right atrium of the heart. The aorta carries oxygenated blood from the heart to the body. The pulmonary artery carries deoxygenated blood from the heart to the lungs/skin. The pulmonary vein carries oxygenated blood from the lungs to the left atrium.
