Understanding Nutrition: Human Nutrition - Digestion, absorption and transport Flashcards

Chyme is:

1. the secretions from the gallbladder that enter the small intestine
2. the product of microbe action on the large intestine
3. partially digested food that travels through the intestinal tract
4. the chewed food that is swallowed

The muscular contractions that move food through the GI tract are called:

1. hydrolysis
2. sphicters
3. peristalsis
4. bowel movements

The main function of bile is to:

1. emulsify fats
2. catalyze hydrolysis
3. slow protein digestion
4. neutralize stomach acidity

The pancreas neutralizes stomach acid in the small intestine by secreting:

1. bile
2. mucus
3. enzymes
4. bicarbonate

Which nutrient passes through the GI tract mostly undigested and absorbed?

1. fat
2. fibre
3. protein
4. carbohydrate

Absorption occurs primarily in the:

1. mouth
2. stomach
3. small intestine
4. large intestine

All bloody leaving the GI tract travels first to the:

1. heart
2. liver
3. kidneys
4. pancreas

Which nutrients leave the GI tract by way of the lymphatic system?

1. water and minerals
2. proteins and minerals
3. all vitamins and minerals
4. fats and fat-soluble vitamins

Digestion and absorption are coordinated by the:

1. pancreas and kidneys
2. liver and gall-bladder
3. hormonal systems and the nervous system
4. vascular system and the lymphatic system

Gastrin, secretion and cholecystitis are examples of:

1. crypts
2. enzymes
3. hormones
4. goblet cells
