Answers
Answer:
Ans1: Lipids (fats and oils): Lipids are digested in the intestine. Lipase enzymes break down the fats into fatty acids and glycerol.
Ans2: (1) Mucoid cells secrete gastric mucus and are common to all types of gastric glands. Mucoid cells are the main cell type found in the gastric glands in the cardiac and pyloric areas of the stomach.
Ans3: Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine. Many waste products, including bilirubin, are eliminated from the body by secretion into bile and elimination in feces.
a) fatty acids and glycerol are the end products of fat after digestion
b) the cells of the stomach wall which secrete mucus are called Goblet cells or mucous cells
c) bile helps in emulsification of fats (process of breakdown of large fat globules into smaller globules)
d) the stomach pushes the bolus into the small intestine... only during vomiting the stomach pushes the food upward
e) the large intestine consists of caecum, ascending colon, transverse colon, descending colon, sigmoid colon
f) digestion does not take place in oesophagus and large intestine in the alimentary canal
g) the process of rhythmic contraction and relaxation movements of the walls of oesophagus which propels the food forward into the stomach is called peristalsis
