The egestion of faeces to the outside through the anal opening (defaecation) is:
1. a voluntary process and is carried out by a mass peristaltic movement.
2. an involuntary process and is carried out by a mass peristaltic movement.
3. a voluntary process and is carried out by an anteperistaltic movement.
4. a voluntary process and is carried out by a peristaltic movement.

Glucose is absorbed in the small intestine and from the lumen passes first to epithelial cell and then to the blood. What would be true regarding absorption of glucose?

1. It enters from the epithelial cell to the blood vessel against its concentration gradient

2. The movement of glucose from the lumen into the epithelial cell requires a facilitated transport protein

3. The movement of glucose from the lumen into the epithelial cell requires an active transport protein and an energy source

4. The movement of glucose from the epithelial cell into the blood vessel requires an active transport protein and an energy source

Emulsification of fats occurs in small intestine and it:
1. Results in the formation of small fat droplets
2. Depends upon the polar structure of bile salts
3. Results in the formation of chylomicrons
4. Depends upon the polar structure of bile pigments

Arrange the following events in chronological sequence [first to last]:
1. protein-coated triacylglycerols enter lacteals
2. triacylglycerol coated with protein
3. fatty acids and glycerol packaged into micelles
4. bile salts emulsify fats
5. lipase digests fat
1. 1,2,4,5,3
2. 2,5,4,3,1
3. 3,5,4,1,2
4. 4,5,3,2,1

Chylomicrons are:

The absorbed substances finally reach the tissues which utilize them for their activities. This process is called:
