How many of the following statements are wrong?

      together into the duodenum as the common

      hepato-pancreatic duct which is guarded by 

      sphincter of Boyden.

b. The parotid, sub-maxillary and sub-lingual

      salivary glands are located just outside the 

      buccal cavity.

c. In duodenum, glands are only found in 

     submucoas which are Brunner's glands, a 

     type of simple branched tubular glands.

d. There is no modification of the four layers

      namely serosa, muscularis, sub-mucosa and

      mucosa in different parts of alimentary canal.

e. lipases are absent in the secretion of gastric

    glands.

(3) Chyle

(4) Food vacuole

Which statement is correct with reference to chylomicron?

1. They are end products of fat digestion

3. This is the form in which digested fats are absorbed into intestinal cells

4. These are short chains of fatty acids absorbed directly into blood by diffusion
