« SR ZOOLOGY 1 BABY BULLET-Q « UNIT-I: HUMAN ANATOMY AND PHYSIOLOGY-I IA. DIGESTION & ABSORPTION (1 X 2) + (1 X 4) = 6 Marks ROOT POINTS 1. Digestion is the process of conversion of complex and non-diffusible food substances into simple diffusible substances. 2. Absorption is movement of water and digested food into the wall of the alimentary canal and then into blood. 3. Digestion is accomplished by Mechanical and Biochemical processes. 4. - Q The digestive system consists of Alimentary canal (Gut) and its associated glands. 5. T Digestive glands: Salivary glands, Gastric glands, Liver, Pancreas and Intestinal glands. 6. E Small Intestine is the longest part of the alimentary canal and most of the digestion takes place in small intestine. L 7.

Liver is the largest gland in the body which secretes bile juice. [IPE] A 12. Bile juice plays an important role in lipid(fat) digestion. [IPE] B 13. Bile salts help in the emulsification of Fats. Bile activates lipases. [IPE] FRUITY Qs OF IPE (1 X 2) + (1 X 4) = 6 Marks 1. Give the dental formula of adult human beings. 2.
