Question

1. what is glomerulus ? what role does it play during urine formation

2. Why villi are richly supplied with blood vessels ?

3. State the role of the following in the digestion of food in humans
I) Pancreatic juice
ii) Bile juice

answers All the questions .... it is important​

Answer 1

Ciao ,
1,glomerulus is the network of capillaries inside the bowman ' s capsule. blood pressure in them cause the production of a filtrate which has nitrogenous wastes and other substances in it except blood cells knows as glomerular filtrate this filtrate then move to the whole network of nephron . and thus urine is produce by this filtrate.
2, villi are richly supplied with blood vessels because simple sugars and amino acuds are absorbed by diffusion or active transport into the blood capillaries. some of yhe fatty acids and glycerol enter into blood stream.
3, pancreatic juice has all enzymes which digest all components of food .e.g : amylas which digests carbohydrates also known as amylopsin. lipase which digests fats into fatty acids and glycerol.
and tripsin which splits proteins into peptones and poly peptides.
4,bile juice contains bile salts which act on fats and emulsifies them.
i really hope that it will be helpful for you but if you have any problem about this topic you can sy .i will make that clear.stay blessed☺

$\huge\bold{Question :}$ 1. what is glomerulus ? what role does it play during urine formation

2. Why villi are richly supplied with blood vessels ?

3. State the role of the following in the digestion of food in humans

I) Pancreatic juice

ii) Bile juice .

$\huge\underline\mathfrak{Answer :}$

1) glamorous it is a bundle of a blood capillaries in the bowman's capsule of nephron .

$\huge\bold{Function :-}$
The waste material of the blood are filtered out in glomerulus rules of a bowman's capsule

ii) the filtered offset is known as globe Maria filtrate which contain sodium potassium and chloride ions glucose ammonia acid urea uric acid and large amount of water .

2. the blood vessels take the observed food to each and every cell of the body where it is utilised or obtaining energy building up new tissues and the repair of the old tissues .

3. $\huge\bold\red{Pancreatic\: Juice :-}$ The pancreatic juice contains exams like corruption or digestion proteins and lipids for breaking down emulsified fats

$\huge\bold\blue{Bile\: Juice :-}$ It helps to break down the largest globules of the flags into smaller give us thereby increasing the offences e of exams action bile salts make the acidic food coming from stomach to alkaline which is necessary for the action of the pancreatic exazymes .
