2. Transporting nutrient-rich blood from intestines to liver for processing before systemic circulation (correct answer)
3. Removing waste products from liver and transporting them to kidneys for elimination
4. Carrying bile from liver to gallbladder for storage and concentration purposes

Question 6

1. Amylase, which breaks down complex carbohydrates
2. Lipase, which breaks down dietary fats
3. Trypsin, which cleaves proteins into peptides (correct answer)
4. Maltase, which converts disaccharides to monosaccharides

Question 7

1. Urethra, which eliminates urine from the body
2. Ureter, which transports urine to the bladder (correct answer)
3. Renal artery, which supplies blood to kidneys
4. Collecting duct, which concentrates urine in kidneys

Question 8

1. Glomerular capsule, which filters blood plasma
2. Proximal tubule, which reabsorbs nutrients
3. Collecting duct, which concentrates urine (correct answer)
4. Renal cortex, which houses filtering units

Question 9

1. Filtering blood to remove waste products from circulation
2. Collecting urine from nephrons and funneling it to the ureter (correct answer)
3. Producing hormones that regulate blood pressure and cell production
4. Reabsorbing essential nutrients and electrolytes for homeostasis

Question 10

1. Parietal cells, which secrete hydrochloric acid for digestion
2. Chief cells, which produce inactive enzymes for protein digestion (correct answer)
3. Mucous cells, which create protective barriers against acid
4. G cells, which release gastrin hormone to stimulate secretions

Question 11

1. Presence of proteins stimulating enzyme production in intestine
2. Detection of fats causing cholecystokinin release in duodenum (correct answer)
3. Acidic chyme triggering bicarbonate secretion from pancreas
4. Stomach stretch receptors signaling beginning of digestion

Question 12

1. Intrinsic factor, which is essential for vitamin B12 absorption in the intestines
2. Hydrochloric acid, which creates the acidic environment needed for enzyme activation (correct answer)
3. Gastrin hormone, which stimulates additional gastric secretions and digestive processes
4. Mucus secretions, which protect stomach walls while facilitating enzyme interactions

Question 13

1. Jejunum, the middle section specialized for nutrient absorption
2. Duodenum, which receives stomach contents and digestive secretions (correct answer)
3. Ileum, the final section that connects to the large intestine
4. Cecum, the first part of the large intestine

Question 14

1. Teeth, which crush and grind food into smaller pieces (correct answer)
2. Salivary glands, which produce digestive enzymes
3. Tongue, which moves food and forms a bolus
4. Hard palate, which provides a firm chewing surface

Question 15

1. Stimulating aldosterone production to increase sodium reabsorption in kidney tubules
2. Increasing water reabsorption in collecting ducts to concentrate urine and conserve body water (correct answer)
3. Promoting red blood cell production when oxygen levels in blood become insufficient
4. Activating renin-angiotensin system to regulate blood pressure and kidney perfusion

Question 16

1. Stomach, where acid begins nutrient breakdown
2. Small intestine, where villi maximize absorption (correct answer)
3. Large intestine, where water and minerals absorb
4. Pancreas, where enzymes process nutrients

Question 17

1. Filtering waste products from blood to produce urine
2. Storing urine temporarily until voluntary elimination occurs (correct answer)
3. Concentrating urine by reabsorbing water and electrolytes
4. Producing hormones that regulate kidney function

Question 18

1. Liver, which produces bile and various blood proteins
2. Pancreas, which produces digestive enzymes and glucose-regulating hormones (correct answer)
3. Gallbladder, which stores bile and releases digestive hormones
4. Salivary glands, which produce saliva and digestive hormones

Question 19

1. Producing saliva that lubricates food for easier swallowing
2. Covering the trachea to prevent food from entering the airway (correct answer)
3. Contracting rhythmically to push food down the esophagus
