Which of the following organs produce insulin, required for glucose uptake into body cells?

Step 1: Red blood cells are least adapted for being in lymph (lymph contains very few red blood cells compared to blood in arteries and veins). D D Step 2: The structure that transports nutrients from the small intestine to the liver is the hepatic portal vein. B B Step 3: The liver does not perform mechanical digestion of food (its functions include bile production, detoxification, storage of glycogen, and protein synthesis). D D Step 4: The pancreas secretes enzymes into the small intestine (duodenum). Gall bladder stores bile, liver produces bile, appendix has no role. B B Step 5: The gall bladder stores bile. A A Step 6: The duodenum is the first part of the small intestine. Large intestine follows small intestine, stomach precedes small intestine, pancreas is accessory gland. B B Step 7: Water absorption mainly occurs in the large intestine. A A Step 8: The ileum is the final section of the small intestine (most nutrient absorption occurs here). D D Step 9: The liver produces bile. C C Step 10: The thyroid gland is not involved in digestion (salivary glands, liver, pancreas are). D D
