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

Show answer
Correct Option: B
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.

  2. Jaundice

  3. Diarrhea

  4. Vomiting

Show answer
Correct Option: A
Explanation:
When the food is not properly digested leading to a feeling of fullness, that condition, is indigestion. The causes of 
indigestion are inadequate enzyme secretion, anxiety, food poisoning, over eating and spicy food.

  1. Eating raw food

  2. Refrigerating the food

  3. Thawing of food again and again

  4. None of the above

Show answer
Correct Option: B
Explanation:

Serve food right away or refrigerate it after it has been cooked or reheated. Leaving food out at room temperature can encourage growth of bacteria. Wash work surfaces frequently to avoid spreading germs from one food item to another. Use the refrigerator to thaw frozen items or try putting plastic-wrapped frozen items in a bowl of cold water to thaw.

biology digestive system of human assimilation of food and egestion assimilation of food components and importance of food

  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

Show answer
Correct Option: C
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'.

Which of the following is not constituent of faeces of a healthy individual?

  1. Dead mucosal cells

  2. Cholesterol

  3. Fat

  4. Glucose

Show answer
Correct Option: D
Explanation:

Faces of a healthy person contain a small amount of metabolic waste products like bilirubin and biliverdin that provides colour to it, dead mucosal cells from the lining of the gut, little amount of cholesterol, fat etc.

So the correct option is 'Glucose'.

Which of the following is known as the building block of proteins?

  1. Amino acids

  2. Enzymes

  3. Fatty acids

  4. Glycogen

Show answer
Correct Option: A
Explanation:

Amino acids are directly absorbed into blood stream. Blood carries these amino acids to the tissues where they become part of the metabolic pool, from which body proteins are synthesized. Hence, it is known as the building block of proteins.

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

biology digestive system of human assimilation of food and egestion assimilation of food components and importance of food

  1. Stercobilinogen

  2. Stercobilin

  3. Derivatives of bilirubin

  4. All of the above

Show answer
Correct Option: D
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'.

Constipation is a condition in which defecation occurs inky at prolonged intervals. It is irregular or inadequate defecation. Which of the following conditions is not responsible for constipation?

biology digestive system of human assimilation of food and egestion assimilation of food components and importance of food

  1. Decreased colon motality

  2. A diet containing too little fluid and fibre

  3. Haemorrhoids

  4. Too much absorption of water by colon

Show answer
Correct Option: C
Explanation:
  • Haemorrhoids are also known as piles.
  •  In Haemorrhoids, swellings contain enlarged blood vessels found inside or around the bottom (the rectum and anus). 
  • A lump hanging down outside of the anus, which may need to be pushed back in after passing a stool. a mucus discharge after passing a stool.
  • Hence, Constipation is a condition in which defecation occurs inky at prolonged intervals. It is irregular or inadequate defecation. Haemorrhoids is not responsible for constipation.
  • So, the correct answer is 'Haemorrhoids'.

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

biology digestive system of human assimilation of food and egestion assimilation of food components and importance of food

  1. Absorption

  2. Assimilation

  3. Digestion

  4. Ingestion

Show answer
Correct Option: B
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.
