Question

"Superior vena cava carries completely digested substances"

How far the statement is correct ? With explanation.​

Answer 1

The superior vena cava returns deoxygenated blood from the upper body to the heart and does not carry completely digested substances.

Step-by-step explanation:

The statement "Superior vena cava carries completely digested substances" is not correct. The superior vena cava is a large systemic vein but its function is to return deoxygenated blood from the upper portion of the body back to the right atrium of the heart, not to carry nutrients or digested substances.

Systemic circulation involves the flow of blood away from the heart to various organs and tissues in the body and then the return of this blood to the heart. The superior vena cava drains blood from areas including the brain, via the jugular vein, and from the arms. This vein, along with the inferior vena cava, plays an essential role in the venous return of the systemic circuit.

Answer 2

Yes.

Step-by-step explanation:

As a blood vessel, Superior vena cava carries completely digested substances that is present in the blood from upper part of the body to the heart. Blood is a fluid that transport digested food from small intestine to other parts of the human body. It also carries oxygen from the lungs to the cells and also carries carbondioxide from the cells to lungs so we can say that Superior vena cava carries completely digested materials.
