Multiple choice hunger and dehydration from tasting to digestion digestion of food digestion evs

Amount of water present inside human body cells is about

  1. 15 litres

  2. 5 litres

  3. 25 litres

  4. 10 litres

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • About 60% of human body weight is due to water and is mainly present within the cells of the body.
  • Intracellular fluid (within the cell) constitutes about 2/3 of body water.
  • Eg- In a person weighing 72 kg, 40 litres of fluid is present in the body out of which about 25 litres of water is present in the intracellular region (within the cells).
  • So, the correct answer is '25 litres'.

A person is given a ............. when he has loose motion and vomiting.

  1. Salt solution

  2. Glucose solution

  3. ORS

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Vomiting and lose motion causes dehydration. Hence, the intake of fluids to maintain the electrolytes is balanced. Oral rehydration therapy (ORT) is a type of fluid replacement used to prevent and treat dehydration, especially due to diarrhoea. It involves drinking water with modest amounts of sugar and salts, specifically sodium and potassium.

So, the correct answer is 'All of the above'.

In extremely serious situations, fluids should be given

  1. Orally

  2. Intradermally

  3. Intravenously

  4. None of the above

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

Children and adults who are severely dehydrated should be treated by emergency personnel arriving in an ambulance or in a hospital emergency room, where they can receive salts and fluids through a vein (intravenously) rather than by mouth. Intravenous hydration provides the body with water and essential nutrients much more quickly than oral solutions, do something that's essential in life-threatening situations.

Partially digested food in ruminants is

  1. Chyme

  2. Cud

  3. Bolus

  4. All of the above

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

Ruminants are mammals that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through bacterial actions. The process typically requires the fermented cud to be regurgitated and chewed again. The process of re chewing the cud to further break down plant matter and stimulate digestion is called rumination. Thus, option B is correct. Chyme is the semifluid mass of partly digested food that is expelled by the stomach into the duodenum and moves through the intestines during digestion. Bolus is a small rounded mass of a substance, especially of chewed food at the moment of swallowing.

The opening of the stomach in duodenum is regulated by  

  1. Sphineter of Oddi

  2. Pyloric sphincter

  3. Gastro-oesophageal

  4. Ileo-caeeal valve

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

A. Sphincter of Oddi is the opening of the hepatopancreatic duct into duodenum.

B. Pyloric sphincter is found between the duodenum and posterior stomach. It regulates the opening of duodenum into stomach.
C. Gastro-oesophageal sphincter is found between the oesophagus and stomach.
D. Ileo-caecal valve is present between ileum of small intestine and caecum of large intestine.
So, the correct answer is 'Pyloric sphincter'.

Which animal out of the following has the longest food-pipe?

  1. Girraffe

  2. Camel

  3. Whale

  4. Yak

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The esophagus commonly known as the food pipe or gullet (gut), is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach.The giraffe has the longest neck of any land mammal, due to which the food pipe Measures about 6.5 feet in length, making it an animal with the longest food pipe as well.
So, the correct answer is 'Giraffe'.

Digestion of starch starts from

  1. Stomach

  2. Intestine

  3. Oesophagus

  4. Mouth

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

Digestion starts in mouth and starch is the biomolecule whose digestion is first carried out by Ptyalin enzyme present in saliva.
No digestion occurs in oesophagus. It functions to transport semi solid bolus of food from mouth to stomach.
Intestine comes after stomach. Stomach is important for digestion of proteins.

Digestion of food in human starts from

  1. Duodenum

  2. Small intestine

  3. Mouth

  4. Large intestine

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

Digestion of food starts in mouth. It is carried out in following two ways

  • Mechanical digestion which is breaking of food into smaller chunks with the help of teeth and aided by muscular tongue.
  • Chemical digestion due to ptyalin (salivary amylase) in saliva
  • So, the correct answer is 'Mouth'
