Multiple choice zoology excretion to maintain homeostasis haemodialysis kidney dialysis kidney disorders

Cleaning of blood of a person with the help of a kidney machine is known as

  1. Paralysis

  2. Alcoholysis

  3. Hydrolysis

  4. Dialysis
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Haemodialysis is a method for removing waste products such as creatinine and urea, as well as free water from the blood when the kidneys can not work properly. The mechanical device used to clean the patient's blood is called a dialyzer, also known as an artificial kidney.

Significantly higher level of urea in the blood is the indication of

  1. Liver damage

  2. Kidney damage

  3. Heart attack

  4. Spleen damage
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Blood urea nitrogen (BUN) measures the amount of urea nitrogen, a waste product of protein metabolism, in the blood. Urea is formed by the liver and carried by the blood to the kidneys for excretion. Because urea is cleared from the bloodstream by the kidneys, a test measuring how much urea nitrogen remains in the blood can be used as a test of renal function. Diseased or damaged kidneys cause an elevated BUN because the kidneys are less able to clear urea from the bloodstream. In conditions in which renal perfusion is decreased, such as hypovolemic shock or congestive heart failure, BUN levels rise. A patient who is severely dehydrated may also have a high BUN due to the lack of fluid volume to excrete waste products.

Therefore, the correct answer is option B.

Dialysis is meant for

  1. Kidney

  2. Gall bladder

  3. Lung

  4. Liver
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Kidney dialysis is a life-support treatment that uses a special machine to filter harmful wastes, salt, and excess fluid from your blood. This restores the blood to a normal, healthy balance. Dialysis replaces many of the kidney's important functions. There are different types of kidney dialysis, including hemodialysis- blood is filtered using a dialyzer and dialysis machine and peritoneal dialysis- blood is filtered inside the body after the abdomen is filled with a special cleaning solution.

Therefore, the correct answer is option A.

Haemodialysis is carried out in the case with a sever defect in

  1. Kidney

  2. Liver

  3. Pancres

  4. Gall bladder
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Dialysis is the artificial process of eliminating waste (diffusion) and unwanted water (ultrafiltration) from the blood. Our kidneys do this naturally. Some people, however, may have failed or damaged kidneys which cannot carry out the function properly - they may need dialysis.
Dialysis may be used for patients who have become ill and have acute kidney failure (temporary loss of kidney function), or for fairly stable patients who have permanently lost kidney function.
Therefore, the correct answer is option A.

The process used in separating larger particles from smaller ones in a solution is called

  1. Chromatography

  2. Dialysis

  3. Osmosis

  4. Tyndallisation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The process of filtering the blood by the artificial kidney is known as dialysis. It is a method of removing excess water, nitrogenous wastes (urea), toxins from the blood in the patient who is rapidly developing loss of kidney function. In dialysis, the larger particles like proteins are separated from smaller particles(nitrogenous waste) in a solution called dialysis fluid.

So, the correct answer is 'Dialysis'.

Haemodialysis is carried out in case of severe defect in 

  1. Kidney

  2. Liver

  3. Lung

  4. Stomach
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The process of filtering the blood by the artificial kidney is known as hemodialysis. It is a method of removing excess water, nitrogenous wastes (urea), toxins from the blood in the patient who is rapidly developing loss of kidney function. It is also called renal replacement therapy. Hence haemodialysis is carried out in case of the severe defect in kidney.

So, the correct answer is 'Kidney'.

Following are four statements. Find out the correct combination. 
1. Glucose has high threshold value.
2. Urine is concentrated in Henles loop. 
3. Haemodialyser removes urea, uric acid, glucose and proteins. 
4. In glomerulus, urea, uric acid, water, glucose and plasma proteins are filtered out

  1. $1, 3, 4$
  2. $2, 3, 4$
  3. $1, 2$
  4. $1, 3$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

1) The substances which are present in blood on being filtered into the tubule are completely reabsorbed are called as high threshold substance. For example, Glucose, NaCl.Hence Glucose has a high threshold value.

2) Urine in concentrated in heles loop through a countercurrent mechanism. The flow of filtrate in the two limbs of Henle’s loop is in opposite directions and thus forms a counter current. The flow of blood through the two limbs of vasa recta is also in a countercurrent pattern. The proximity between the Henle’s loop and vasa recta, as well as the countercurrent in them, help in maintaining the concentration of urine.
So, the correct answer is '1,2'.

D Correct answer
Explanation
Hemodialysis is a method for removing waste products such as creatinine and urea, as well as free water from the blood when the kidneys are in kidney failure. The mechanical device used to clean the patient's blood is called a dialyser, also known as an artificial kidney.

So, the correct option is 'Dialyser'.

Dialysis fluid contains all the constituents as in plasma except

  1. Electrolytes

  2. Proteins

  3. Nitrogenous wastes

  4. All the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The process of filtering the blood by the artificial kidney is known as dialysis. It is a method of removing excess water, nitrogenous wastes (urea), toxins from the blood in the patient who is rapidly developing loss of kidney function. It is also called renal replacement therapy. Dialysis fluid contains all constituents as in plasma except nitrogenous waste (Urea)

So, the correct answer is 'Nitrogenous waste'.
