Test: Other Organs Involved in Excretion & Disorders of Excretory System - NEET MCQ

Artificial kidney (Dialysing unit ) is a machine that is used for filtration of blood in the people whose kidneys are failed or damaged by the process called Dialysis.

Dialysis fluid is produced by the blending of treated water with electrolytes at the patient's bedside. The composition of the dialysis fluid should match that of plasma except for the nitrogenous waste (urea).

So the answer is 'No urea'.

Glycosuria is the excretion of glucose into the urine. Urine contains no glucose in the normal condition because the kidneys are able to reclaim all of the filtered glucose back into the bloodstream. Glycosuria is caused by elevated blood glucose levels, most commonly due to untreated diabetes mellitus
So, the correct answer is 'High amount of sugar in urine'.

Haemodialysis is associated with the kidneys. This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure. Hemodialysis is one of three renal replacement therapies (the other two being kidney transplant and peritoneal dialysis).

The lungs play a crucial role in the elimination of wastes by removing significant quantities of carbon dioxide (CO2) and water from the body. Every minute, approximately 200mL of CO2 is eliminated through respiration, along with considerable amounts of water vapor. This process is essential for maintaining the body's acid-base balance and ensuring that harmful waste gases are expelled.

Sebaceous glands are responsible for eliminating specific substances like sterols, hydrocarbons, and waxes through the secretion of sebum. Sebum provides an oily protective covering for the skin, preventing it from drying out and helping to maintain skin health. This gland's function is crucial for skin protection and overall skin condition.
