Excretory System

Hydrostatic pressure in glomerular capillaries is approximately:

Correct option is C, 45–60 mmHg. In Excretory System, the accurate description is 45–60 mmHg, and that is what you should commit to memory. Keep the definition tight and the role clear — 45–60 mmHg is the option that correctly names the structure, process, or principle asked for in Excretory System. Then 45–60 mmHg is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto 45–60 mmHg. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.

Excretory System

Cortical nephrons constitute approximately what percentage of total nephrons?

Answer: D) 85%. For Excretory System, once you lock onto the key mechanism or definition, 85% is the clear fit. If you restate the concept in your own words, 85% is the option that correctly names the structure, process, or principle asked for in Excretory System. So 85% is the clean, accurate selection. If a similar stem appears later, start from the same core fact and you will land on the same kind of answer. In class notes, highlight this same phrase next to the related diagram so the wording and the picture reinforce each other. When you practise, cover the choices first, write 85% from memory, then reveal the letter — that habit builds real recall for Excretory System.

Excretory System

Loop of Henle is essential mainly for:

Urine concentration (B) is the right choice. This sits at the heart of Excretory System: the wording points straight to what is happening in the tissue or organ system. A useful study habit is to ask what the structure or process is for: the functional job described in the stem is exactly what Urine concentration does in Excretory System. That reasoning supports Urine concentration. One solid sentence about why this works is enough for recall — you do not need a long essay for every MCQ. When you practise, cover the choices first, write Urine concentration from memory, then reveal the letter — that habit builds real recall for Excretory System.

Excretory System

Which part of nephron primarily reabsorbs water and solutes?

Correct option is C, Proximal tubule. In Excretory System, the accurate description is Proximal tubule, and that is what you should commit to memory. Keep the definition tight and the role clear — the functional job described in the stem is exactly what Proximal tubule does in Excretory System. Then Proximal tubule is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Proximal tubule. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.

Excretory System

Functional unit of kidney responsible for urine formation is:

The correct answer is B: Nephron. In Excretory System, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, the functional job described in the stem is exactly what Nephron does in Excretory System. That is why Nephron is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.
