Which of the following is the stomach part in which herbivores secretes the grass which is swallowed quickly?

  1. Lumen

  2. Pyloric

  3. Rumen

  4. Ileum
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • The animals which partially digest food have a four-chambered stomach and the process of digestion is as follows: The food is chewed and swallowed quickly and passed into the first stomach called Rumen.
  •  Then the microorganisms help in breaking down the food and this partially digested food is called cud. Hence, the rumen is the stomach part in which herbivores secretes the grass which is swallowed quickly.
So, the correct answer is 'rumen'.

B Correct answer
Explanation

  • The animals which partially digest food have four chambered stomach and the process of digestion is as follows: The food is chewed and swallowed quickly and passed into the first stomach called Rumen.
  •  So, the animals are referred to as ruminants. Then the microorganisms help in breaking down the food and this partially digested food is called cud. Hence, Partially digested food in ruminants is cud.
So, the correct answer is 'cud'.

Digestion of food in ruminants takes place with the help of

  1. Virus

  2. Protozoa

  3. Bacteria

  4. Parasite

C Correct answer
Explanation
The four-chambered stomach of ruminants contain bacteria. The plant material ruminants eat contain cellulose. These bacteria help in the break down of cellulose with the help of enzyme called cellulase.
So the correct answer is 'Bacteria'.

Which of the following is responsible for partial digestion in the mouth of ruminants?

  1. High intake of cellulose

  2. High intake of lactose

  3. High intake of glucose

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Ruminants eat plant materials that contain cellulose. High intake of cellulose is responsible for partial digestion in the mouth. This partial digestion of cellulose is called cud. It is digested partially in the mouth by the process of regurgitation.
So the correct answer is 'High intake of cellulose'.

Assertion    :  Rumen of alimentary canal of ruminant
                        animals harbour numerous bacteria and
                           protozoa

Reason      :    Bacteria and protozoa help in the secretion
                        of gastric juice in the rumen.


  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

C Correct answer
Explanation

Ruminant animals such as cattle, buffalo, sheep, goat and camel have a compound stomach, which consists of four chamber, viz, rumen, reticulum, omasum and abomasum. Rumen is the first and the largest of the four chambers. Rumen and reticulum harbour numerous bacteria and protozoa, which carry out extensive fermentation of cellulose. So, these two chambers function as sites for cellulose digestion in ruminants. The gastric juice containing enzymes and HCl is secreted only by the fourth chamber i.e., Abomasum.
