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

The correct answer is Vena cava

Concept:

• Frogs have a three-chambered heart consisting of two atria and one ventricle. Their circulatory system is a double circulation system, meaning blood flows through the heart twice before completing a full circuit.
• Deoxygenated blood from the body is returned to the heart through the vena cava, which is the main vein responsible for transporting this blood.
• The vena cava carries deoxygenated blood from the various tissues and organs to the right atrium of the frog's heart.

Explanation:

• The vascular system of frog is well-developed closed type.
• Frogs have a lymphatic system also. The blood vascular system involves heart, blood vessels and blood.
• The lymphatic system consists of lymph, lymph channels and lymph nodes.
• The heart is a muscular structure situated in the upper part of the body cavity.
• It has three chambers, two atria and one ventricle and is covered by a membrane called pericardium.
• A triangular structure called sinus venosus joins the right atrium.
• It receives blood through the major veins called vena cava.
