Hint:  It is the body's most extensive form of veins. It fixed to the heart's right atrium.


Complete Answer:

For the circulatory system to work, the operation of the heart, lungs, veins, and capillaries are important. The basic function of the circulatory system is to move the lymph and blood throughout the body. This will provide the body with oxygen and nutrients and eliminate waste materials from the bloodstream, and it will also be involved in controlling body temperature and helping prevent infection.


Now, let us find the solution from the options- 

1) Vena Cava is the largest form of vein in the body, pumping deoxygenated blood from the body to the heart's right atrium.

It sends deoxygenated blood back into the heart from the body.

Two forms of vena cava supply the heart with blood. They are superior Cava vena and inferior Cava Vena.

(i) Superior vena cava and inferior vena cava transport impure blood from body tissue into the heart. 

The superior vena cava pumps deoxygenated blood into the right auricle from the head, chest and upper limbs. 

(ii) The inferior vena cava pumps deoxygenated blood to the right auricle from the organs below the diaphragm.


2) Aorta is the main artery leaving the heart from the left ventricle. It fills the whole body with oxygenated blood.


3) The flow of oxygenated blood around and from the lungs is of concern to the pulmonary veins.


4) The pulmonary arteries' basic function is to transport blood low in oxygen and high in carbon dioxide to the lung capillaries, in which such exchange occurs.


Thus, the correct answer is option (A) Vena cava.


Note: Vena cava has two main trunks, the anterior and posterior vena cava which carry deoxygenated blood to the right side of the heart. The anterior vena cava, recognized as the precava, pumps the body's head end while the posterior vena cava, or postcava, pumps the tail or end of the rear. In mammals, these veins are named as the superior and inferior venae cavae, respectively. Considering that many mammals including humans only have one anterior vena cava, and two in other species.
