4. In humans, sphincter of oddi is associated with the opening of ________
a) Hepatopancreatic ampulla
b) Pyloric stomach
c) Esophagus
d) Common hepatic duct
View Answer
Explanation: The opening of Hepatopancreatic ampulla in the duodenum is guarded by a sphincter of oddi. Daily secretion of bile is about 600-1200ml.
5. Cholecystokinin stimulates ______________
a) Pancreas
b) Gall bladder
c) Secrete bile
d) Kidneys
View Answer
Explanation: Present on lower surface of right liver lobe, there is a thin walled pear shaped sac called gall bladder. It concentrates and stores the bile secreted by liver.
6. Pancreas is a _________ gland.
a) Heterocrine
b) Endocrine
c) Exocrine
d) Hormone
View Answer
Explanation: Pancreas is a Heterocrine gland. Its exocrine part is formed of a large number of lobules or acini.
7. Where is Pancreas located?
a) Below stomach
b) In-between stomach and liver
c) Behind the stomach
d) Above the stomach
View Answer
Explanation: Pancreas are about 6 inches long. It is a 2nd largest gland. It is dived into the head body and tail. It sits in the abdomen behind the stomach and in front of the sine.
8. Which cells in the pancreas make insulin?
a) Germ cells
b) Islet cells
c) Epithelial cells
d) Hepatic cells
View Answer
Explanation: Islets are tiny clusters of cells in the pancreas. These make insulin which controls blood sugar levels.
9. What does pancreas make?
a) Enzymes
b) Carbohydrates
c) Fats
d) Muscles
View Answer
Explanation: Enzymes are proteins that boost the rate of reaction. Enzymes in pancreas combine with bile to break down the food.
10. One can live without a pancreas.
a) True
b) False
View Answer
Explanation: It is possible to live without a pancreas. Pancreas secretes insulin. By depending on insulin shots it’s possible to live. It’s hard to mange as pancreas makes other hormones that control blood sugar.
11. Average PH of urine is _________
a) 6
b) 9
c) 3
d) 7
View Answer
Explanation: Urine consists of urea. The ph is slightly acidic.
12. Henle’s loop is found in ___________
a) Liver
b) Kidney
c) Pancreas
d) Stomach
View Answer
Explanation: Henle’s loop is a long U-shaped tube that conducts urine within each nephron. Its function is to recover water and sodium chloride from urine.
13. Which among the following is structural and functional unit of a kidney?
a) Nephron
b) Neuron
c) Urethra
d) Henle’s loop
View Answer
Explanation: Nephron is a structural and functional unit of kidney. Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering blood, reabsorbing what is needed and excreting the rest as urine.
14. The liquid which collects in Bowman’s capsule is __________
a) Concentrated urine
b) Blood plasma minus proteins
c) Glycogen and water
d) Urea, glycogen and water
View Answer
Explanation: Bowman’s capsule is a cuplike sack at the beginning of the tubular component of a nephron, it performs the first step in the filtration.
15. In which of the following region f nephron does maximum reabsorption of useful materials occur?
a) Loop of Henle
b) Glomerulus
c) DCT
d) PCT
View Answer
Explanation: PCT stands for proximal convoluted tubule. This is the first part of the renal tubule and it lies in the cortex of the kidney, close to the renal corpuscle.
