Occurence of excess urea in blood due to kidney failure is

  1. Urochrome

  2. Uraemia

  3. Uricotelism

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

Accumulation of urea in body is called uraemia. It may be due to kidney failure and other metabolic waste products may also accumulate. Uraemia develops after about 7 days of anuria (absence of urine) because of the reduced glomerular filtration rate and impaired tubular secretion of urea. Increased blood urea usually leads to confusion and mental disorientation.

  1. The excretion volume of urine increases

  2. The excretion volume of urine decreases

A Correct answer
Explanation

Oliguria is the condition of less than 400 ml of urine per day in adults, whereas severe oliguria means less than 100 ml of urine per day in adults.

Assertion  :  Phenylketonuria is a recessive hereditary disease caused by the body's failure to oxidize an amino acid phenylalanine to tyrosine, because of a defective enzyme

Reason    :    It results in the presence of phenylalanine in the urine


  1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion

  2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion

  3. If the assertion is true but the reason is false

  4. If both the assertion and reason are false

  5. If the assertion is false but reason is true
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Phenylketonuria results when there is a deficiency of liver enzyme phenyl alanine hydroxylase that converts phenyl alanine into tyrosine. It results with a high level of phenyl alanine in blood, tissue fluids and urine.

So, the correct answer is 'If both the assertion and reason are true but the reason is not a correct explanation of the assertion'

  1. Dializer

  2. Haemocytometer

  3. Auto analyser

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

  • Dialysis is an artificial procedure of excretion of metabolites from the blood when kidneys do not work. 
  • In this process, the harmful waste products are removed from the blood. The dialysis apparatus of the dialyzer is commonly known as an artificial kidney.
  • The process of dialysis is generally recommended for the person who has been suffering problems related to the kidney and the kidney is not functioning properly.
Thus, the correct answer is option A.

Diuresis is a specific pathological condition which leads to

  1. Increased volume of urine excretion

  2. Decreased volume of urine excretion

  3. Increased glucose excretion

  4. Decreased electrolyte concentration
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Diuresis as a pathological condition occurs  under hyposecretion of ADH or Vasopressin, which affects the water rreabsorption by the tubule into the blood by the peritubular network.This results in excretion of dilute urine. A disorder known as diabetes insipidus.

So, the correct answer is 'Increased volume of urine excretion'

Multiple choice zoology excretory system of human disorders of excretory system disorders related to the excretory system functions and disorders of kidney

Diabetes insipidus is due to

  1. Hyposecretion of vasopressin(ADH)

  2. Hypersecretion of insulin

  3. Hyposecretion of insulin

  4. Hypersecretion of vasopressin (ADH).
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Diabetes insipidus (DI) is an uncommon condition in which the kidneys are unable to prevent the excretion of water. The amount of water excreted in the urine is controlled by antidiuretic hormone (ADH). ADH is also called vasopressin. ADH is produced in a part of the brain called the hypothalamus. It is then stored and released from the pituitary gland. This is a small gland just below the base of the brain. DI caused by a lack of ADH is called central diabetes insipidus. When DI is caused by a failure of the kidneys to respond to ADH, the condition is called nephrogenic diabetes insipidus.  Nephrogenic means related to the kidney.

So, the correct option is 'Hyposecretion of vasopressin'.
