A) villus of intestine
B) kidneys
C) liver
D) lungs
Correct Answer: A
Solution :
Lacteals are minute blind-ended lymph vessels that occur in each villus of the small intestine. Digested fats are absorbed into the lacteals and transported to the blood stream through thoracic duct. A single mammalian kidney contains about a million of nephron. Each of these is composed of a glomerulus that is connected to a nephron tube which is called renal tube. Between its proximal and distal segments, each renal tubule is folded into a hairpin loop called loop of Henle. Liver is made up of units called lobules, each of which is roughly hexagonal structure consisting largely of hepatocytes arranged around a central vein. Lungs are the respiratory organs of air breathing vertebrates. The membrane of lungs possesses numerous sacs alveolus that are connected to bronchus via bronchioles.
