b. helps in absorption of liquids.

c. stores food

Answer 2

$\large\underline\bold{ANSWER \huge{\checkmark}}$

$\large\underline\red{\bold{\star\:\: pancreatic\:juice,}}$

• it is a liquid ,which is secreted by pancrease
• pancreatic juice are present in pancrease
• it helps in digestion process
• it help by digestion process by making hormones
• it transfers the messages through the blood and are chemical messengers.
• it contains enzyme like ,

1. trypsin
2. tchymotrypsin
3. elastase
4. carboxypeptidase
5. pancreatic lipase
6. amylase
7. nucleases

$\bf\underline\bold{structure,}$

$\sf\dashrightarrow$it's long flat gland which is behind the stomach in upper abdomen.

$\large\underline\red{\bold{VILLI,}}$

• it is present in inner walls of small intestine
• fully are tiny finger like projections from the wall of small intestine
• it's function is to absorb the digested food
• it increases the area surface of small intestine for absorbing nutrients of the digested food
• these absorption of food takes place by the help of many blood vessels which are present in the villi and these are present in the villi and these blood vessels carry it two blood stream, from that it's delivered in every part of cells

bloodvessels$\sf\dashrightarrow$ bloodstream $\sf\dashrightarrow$ every parts of cells.

• these absorbs protein molecules.

$\large\underline\red{\bold{PSEUDOPODIA,}}$

• it includes locomotion and ingestion
• PSEUDOPODIA is combination of two different parts,

$\:\:\:\:\:\:\:\:\:\:\dashrightarrow pseudo- podia \\ pseudo\:--\boxed{false}\\ podia\:--\boxed{feet} \\ \therefore PSEUDOPODIA= false\:feet$

• these process of PSEUDOPODIA is mostly observed in amoeba.
• which is a simple organism,which is unshaped (don't have fixed or proper shape)
• function of PSEUDOPODIA is nothing but ,

sense present of food$\sf\dashrightarrow$ captures food$\sf\dashrightarrow$ digestion takes place $\sf\dashrightarrow$ excreates the waste$\sf\dashrightarrow$ingesting.

$\large\underline\red{\bold{LARGE\:INTESTINE(colon),}}$

• it absorbs water and some salts(electrolytes) from the part of undigested food particles
• it absorbs and produces vitamins
• it throws faeces towards the rectum for ejection of faeces
• it absorbs upto 90% of water.
• there are few scientific named (biological names) which completes these process

1. ascending colon:- it absorbs the water and nutrients and transferring it in form of solids (stool)
2. descent colon:- it stores faeces which will be disburden into rectum.
3. sigmoid colon:- which pressurise the colon, so faeces move towards rectum
4. rectum:- stores the tools Nd ejects them out of the body in form of faeces.
