All of the following symptoms are found in jaundice except

  1. Disorders of hepato-billary system

  2. Abnormal secretion of pancreatic and gastric juices

  3. Bile duct obstruction

  4. Anaemia
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Jaundice is caused due to the high levels of bilirubin in the blood. High bilirubin levels could be due to obstruction in bile duct which would interrupt the drainage of bile containing the bilirubin or the chronic liver disease (hepato-biliary) which decrease the ability of  the liver to metabolize and excrete the bilirubin. Anemia leads to increased excretion of bilirubin in the blood and subsequent decrease in the number of RBC's. Abnormal secretion of pancreatic and gastric juices has nothing to do with bilirubin levels thus are not the symptoms found in jaundice patients.

  1. Defaecation involves both voluntary and involuntary process

  2. Voluntary contractions of abdominal muscles and diaphragm aid in defaecation

  3. Decrease in intra abdominal pressure aids in the process of defaecation

  4. Distention of rectal wall induces defaecation reflex
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Defaecation is the process in which removal of fecal matter outside the body. It involves:-

1)Both voluntary and involuntary process the signal provided can be controlled by the person.
2)Voluntary contractions of abdominal muscles and diaphragm aid in defaecation.
3)Increase in intra abdominal pressure aids in the process of defaecation.
4)Distention of rectal wall induces defaecation reflex.
So the correct option is 'Decrease in intra abdominal pressure aids in the process of defaecation'.

  1. Amino acids

  2. Enzymes

  3. Fatty acids

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

Which of the following pigments are responsible for the brown color of human faeces?

  1. Stercobilinogen

  2. Stercobilin

  3. Derivatives of bilirubin

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

Bilirubin and its derivatives, Stercobilin that is secreted from the liver as the waste material that is formed after the degradation of haemoglobin and

Stercobilinogen is a chemical formed by the bacteria of the gut from the degradation of haemoglobin are responsible for the colour of the faeces.
So the correct option is 'All of the above'.

C Correct answer
Explanation
  • Haemorrhoids are also known as piles.

The process by which the blood carries the absorbed food products to the tissue cells, where they are taken up, is called as

  1. Absorption

  2. Assimilation

  3. Digestion

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

After digestion of complex food into the simple soluble form, the nutrients are absorbed by the small intestine with help of finger-like projection (villi) in the wall of the intestine. The wall of intention is surrounded by the blood vessels which possess assimilation of food. Assimilation is the process of transfer of soluble food from the intestine to different parts of the body through blood.

Therefore, the correct answer is option B.
