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'.

  2. Presence of glucose in urine is glycosuria

  3. Presence of ketose sugar in urine is ketonuria

  4. Presence of excess urea in blood is uremia

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ketonuria is the Presence of the high number of ketone bodies in urine. It may occur due to diabetes, starvation, fasting or glycogen storage disease.
