Absorption Of Digested Products Flashcards
absorption is the process by which the end products of digestion pass through the intestinal mucosa into _____ or ____
blood
lymph
absorption is carried out by which transport mechanisms
active
passive
facilitated
examples of substances absorbed by simple diffusion
small amounts of monosaccharides like glucose
amino acids
some electrolytes like chloride ions
examples of substances absorbed by facilitated transport and their carrier ion
fructose and some amino acids are absorbed with the help of carrier ions like Na+
transport of water depends upon the _______ gradient
osmotic
which substances cannot be absorbed into the blood
fatty acids
glycerol
how are fatty acids and glycerol absorbed then
incorporated into micelles which move to intestinal mucosa
reform into fat globules (trisaccharides) with a protein coating (chylomicron)
chylomicrons are transported to lymph vessels
where does maximum absorption occur
small intestine
what substances are absorbed in the stomach
water
simple sugars
alcohol
etc
which is the principal organ for absorption of nutrients
small intestine
in which organ is digestion completed
small intestine
what is assimilation
absorbed substances finally reach the tissues which utilise them for their activities
