Identify the correctly matched structures and numbers. (Select all that apply)
Glomerulus - 6
PCT-9
Distal convoluted tubule - 8
Nephron loop - 3, 4 and 5
DCT-9
Glomerular capsule - 1
Collecting duct – 1
Correct Answer : D,F
A. Glomerulus – 6: The glomerulus is the capillary tuft labeled 2, not 6.
B. PCT – 9: The proximal convoluted tubule is labeled 7 (first coiled segment after the capsule); there is no 9 shown.
C. Distal convoluted tubule – 8: The DCT is labeled 6 (coiled segment after the ascending limb). 8 points to the collecting system.
D. Nephron loop – 3, 4 and 5: 3 = descending limb, 4 = hairpin turn, 5 = ascending limb.
E. DCT – 9: DCT is 6; no 9 indicated.
F. Glomerular capsule – 1: The capsule (Bowman’s capsule) encasing the glomerulus is labeled 1.
G. Collecting duct – 1: The collecting duct is the long vertical duct on the right (labeled 7/8), not 1.

Correct Answer is B
Explanation
A. Muscularis externa, submucosa, mucosa, serosa: This is out of order -muscularis externa is deeper than serosa but more superficial than the mucosa, so this ordering is incorrect.
B. Mucosa, submucosa, muscularis externa, serosa: The mucosa (deepest layer lining the lumen) → submucosa → muscularis externa → serosa (outermost)is the correct sequence from deep to superficial .
C. Serosa, muscularis externa, submucosa, mucosa: This lists the layers from superficial to deep (reverse of what the question asked), so incorrect for deep to superficial.
D. Submucosa, mucosa, muscularis externa, serosa: This places submucosa deeper than mucosa (wrong); incorrect order.
Correct Answer is ["C","D","E"]
Explanation
A. Converted to carbon monoxide: CO (carbon monoxide) is a different gas and is not a product or transport form of CO₂.
B. Bind to myoglobin: Myoglobin primarily binds O₂ within muscle cells; CO₂ transport by myoglobin is not a main mechanism.
C. Binds to hemoglobin: CO₂ can bind to hemoglobin (forming carbaminohemoglobin) as one transport form.
D. Converted to bicarbonate ions: Most CO₂ is converted to bicarbonate (HCO₃⁻) in red blood cells and transported in plasma.
E. Dissolved in plasma: A small proportion of CO₂ is carried dissolved directly in plasma.
