Question

2. Make a table IN THE FIRST COLUMN LIST all of the GI tract organs in order, include all sphincters; DO NOT INCLUDE ACCESSORY GLANDS IN THE FIRST COLUMN. In the second column, indicate the secretions of that organ – also indicate where glands dump into the system and their secretions, if none empty in at that point – leave it blank. IN the THIRD COLUMN indicate the action of each of the secretions

structure	secretions	Actions of secretions
mouth	Salivary glands secrete alpha amylase	Converts polysaccharides into oligosaccharides and disaccharides
Add as many rows as you need – put each SECRETION on a separate line

Answer 1

QUESTION-1

ANSWER

Structure	Secretions	Actions of secretions
Mouth	Salivary glands secrete alpha-amylase	Converts polysaccharides into oligosaccharides and disaccharides
Esophagus	No secretions. Carries food to the stomach by a process called peristalsis. It contains esophageal sphincter which keeps food in the stomach, does not allow food to move up.
Stomach	Gastric secretions Acid Proteases- Pepsinogen, produced by Chief cells.	Acid activates proteases like pepsinogen into pepsin. Pepsin helps in proteins digestion. It breaks down polypeptides into simpler forms.
Small intestine	Burner's gland secretes highly alkaline mucus. Crypt's of Lieberkuhn produces enterocytes.	Highly alkaline mucus neutralizes the acidity of chyme. Enterocytes secretes a large volume of water and electrolytes.
Large intestine	Crypts of Lieberkuhn produces mucus.	Mucus protects the intestinal walls.

GOOD LUCK.
