Important Questions on Digestion and Absorption


Given below are two statements:
Statement I: Fatty acids and glycerols cannot be absorbed into the blood.

Fill in the blanks with the correct option:
Fatty acids and glycerol being ___(i)___, cannot be absorbed into the blood. They are first incorporated into small droplets called ___(ii)___ which move into the intestinal mucosa. They are re-formed into very small protein-coated fat globules called the ___(iii)___ which are transported into the ___(iv)___ in the villi.

Choose the correct statement out of the following:
(i) Absorption is the process by which the end products of digestion pass through intestinal mucosa into the blood or lymph.
(ii) Absorption is carried out by passive, active, or facilitated transport mechanisms.
(iii) Chylomicrons are very small protein-coated fat globules formed in the intestinal lumen.
(iv) The absorbed substances finally reach the tissues and are utilized for activities by process called egestion.
