Question

A patient in a hospital is undergoing a treatment for some disorder. A machine hemodialyzer is being used to treat the patient. There is an inlet through which blood from patient's body is entering the machine and an outlet tube from the machine is entering the patient body. The organ likely to be affected in the patient body. The organ likely to be affected in the patient and the blood in inlet and outlet tube respectively will be

• A. Lungs, oxygen poor, oxygen rich
• B. Lungs, oxygen rich, oxygen poor
• C. Kidney, urea poor, urea rich
• D. Kidney, urea rich, urea poor

Answer 1

The correct option is D Kidney, urea rich, urea poor

In order for blood to perform its essential functions of bringing nutrients and oxygen to the cells of the body, and carrying waste materials away from those cells, the chemical composition of the blood must be carefully controlled. Blood contains particles of many different sizes and types, including cells, proteins, dissolved ions, and organic waste products. Some of these particles, such as proteins like hemoglobin, are essential for the body. Others, such as urea (a waste product from protein metabolism), must be removed from the blood or they will accumulate and interfere with normal metabolic processes. But the largest responsibility for maintaining the chemistry of the blood falls to the kidneys, a pair of organs located just behind the lining of the abdominal cavity. It is the job of the kidneys to remove the harmful particles from the blood and to regulate the blood's ionic concentrations, while keeping the essential particles in the blood. Dialysis is a process for removing waste and excess water from the blood and is used primarily as an artificial replacement for lost kidney function in people with kidney failure.

Therefore, the correct answer is option D.
