Question

(I) the words that are associated with ruminants are
rumen
pseudopodia
caecum
vacuole
grass
oesophagus
(iii) How are cows able to digest cellulose while humans are not?
(iv)
What is cud? Why do cows chew it?​

Answer 1

Answer:

(iii) Animals like cows and pigs can digest cellulose thanks to symbiotic bacteria in their digestive tracts, but humans can't. It's important in our diets as source of fiber, in that it binds together waste in our digestive tracts.

(iv) Cud is a portion of food that returns from a ruminant's stomach to the mouth to be chewed for the second time. More accurately, it is a bolus of semi-degraded food regurgitated from the reticulorumen of a ruminant.

When cows chew their cuds they secrete saliva. ... This saliva contains a natural antacid which helps to buffer the rumen or first compartment of the stomach. Proper buffering of the rumen allows a cow to digest forages better and to eat more feed which helps her produce more milk

Explanation:

Answer 2

1- rumen

Explanation:

When ruminants quickly swallow the grass and store it in a part of the stomach called rumen.

2- Animals like cow, horse etc have

a large sac-like structure called Caecum

between the oesophagus and the small

intestine. The cellulose of the

food is digested here by the action of

certain bacteria which are not present in

humans.

4- The partially digested food in ruminants is called cud. Later the cud returns to the mouth in small lumps and the animal chews it. This process is called rumination.
