✭Mark T if the statement is true and 'F if it is false :-

(a) Digestion of starch starts in the stomach. (T/F)

▶False, Digestion of starch starts from the mouth mixing food with saliva.

(b) The tongue helps in mixing food with saliva. (T/F)

▶True, The tongue is a muscle having glands, sensory cells, and fatty tissue which helps us to moisten food with saliva.

(c) The gall bladder temporarily stores bile. (T/F)

▶True, Bile juice is produced by the liver and it is temporarily stored in the gall bladder.

(d) The ruminants bring back swallowed grass into their mouth and chew it for some time. (T/F)

ᴀᴅᴅɪᴛɪᴏɴᴀʟ ɪɴғᴏʀᴍᴀᴛɪᴏɴ :-

The digestive system breaks down foods into

usable forms of energy & nutrients from the body, and eliminates wastes.

Mouth :– Break down of food in small pieces & mixing with saliva by chewing.

↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘

Oesophagus :– It is also known as food pipe it carry food from mouth to stomach.

↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘

Stomach :– The stomach contains juices which break down these particles into smaller molecules.

↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘

Small Intestine :– The food is further broken down in the small intestine. Glands like the liver and pancreas produce bile and pancreatic juice, which help in the process. The simple molecules are then absorbed into the blood stream from the small intestine and sent to all the parts of the body.

↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘

Large Intestine :– Here, the water is stored & absorbed from the remaining food .

↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘↘

Rectum :– The leftover solid waste is thrown out of the body through the rectum .
