Which of the following functions is associated with the skin?
Storage of fat
Body temperature regulation
Energy production
Gas exchange
The Correct Answer is B
a: Storage of fat - While the skin does contain adipose tissue (fat), its primary function is not fat storage.
b. Body temperature regulation-The skin plays a crucial role in regulating body temperature through processes such as sweating to cool the body down and constriction of blood vessels to conserve heat.
c: Energy production - The skin is not directly involved in energy production; this is primarily carried out by organs like the liver and muscles.
d: Gas exchange - Gas exchange occurs primarily in the lungs, not the skin.

Correct Answer is D
Explanation
a. Prothrombin: This is a protein involved in blood clotting, not in maintaining colloid osmotic pressure.
b. Globulins: These are involved in immune responses and transportation of substances but are not the primary proteins for colloid osmotic pressure.
c. Fibrinogen: This is a clotting factor that helps in blood coagulation, not in colloid osmotic pressure.
d. Albumin: Albumin is the main plasma protein responsible for maintaining colloid osmotic pressure, which helps to keep fluid within the blood vessels.
Correct Answer is A
Explanation
A. Loop of Henle:After the glomerular filtrate passes through the proximal convoluted tubule, it enters the Loop of Henle. This component of the nephron is responsible for further concentrating the filtrate and plays a critical role in urine concentration.
B. Bowman's capsule:Bowman's capsule is where glomerular filtration begins. It collects the filtrate from the glomerulus, but it is not where filtrate goes after the proximal convoluted tubule.
C. Collecting duct:The collecting duct is the final segment of the nephron where urine is collected after it has passed through the Loop of Henle and distal convoluted tubule. It does not receive the filtrate directly from the proximal convoluted tubule.
D. Glomerulus:The glomerulus is a network of capillaries where filtration of blood occurs, producing glomerular filtrate. It is not a component that the filtrate enters after the proximal convoluted tubule.
