Question

For dead body preservation, fluid is inserted through
(a) Femoral vein
(b) Femoral artery
(C) Brachial vein
(d) Brachial artery

Answer 1

Hint: Dead body preservation requires the injection of certain chemicals and fluids to sterilize the dead body as well as prevent or delay its natural decaying process. The fluid is inserted through the blood vessel that branches from the blood vessel that supplies the brain.

Complete answer:
Embalming is the process of preservation of the dead body by treating them with a mixture of prepared chemicals known as embalming fluid. This fluid is a mixture of formaldehyde, glutaraldehyde, and methanol in specific proportions. It is injected into the arterial systems of the body through the carotid artery which further drains into the brachial artery. It is located in the upper arm and acts as the main supplier of oxygenated blood to the arm.

Additional Information:
-The embalming fluid serves various purposes to preserve a dead body. Like, it denatures cellular proteins and thus no more a nutrient source of bacteria. This cuts off the supply for the growth of bacteria. Any existing ones are also killed by it.
-The blood is drained from the veins of the dead body and the carefully prepared embalming fluid is inserted into the arteries. The main purpose of this process is to give a life-like appearance to the dead body.
-Femoral vein carries deoxygenated blood away from both the upper thighs of the legs and the pelvic region while the femoral artery brings oxygenated blood. The femoral vein drains blood into the inferior vena cava.
-Brachial vein is located in arms primarily in the region between the arms and elbows. The deoxygenated blood from the arm is returned to the heart.
So, the correct answer is ‘Brachial artery.’

Note: Many other chemicals are also mixed in the fluid-like dyes, preservatives, humectants, etc. Dyes help in restoring the natural coloration of the body which may have been heavily deteriorated due to conditions like jaundice. Humectants add moisture to the dehydrated bodies.
