Real questions that test this

सामान्यतः किडनीमधून खालीलपैकी कशाचे गाळण होत नाही ? / Generally through kidney which of the following is not filtered ?

1)अमोनिया / Ammonia
2)यूरीक अॅसीड / Uric acid
3)पाणी / Water
4)साखर / Sugar✓ Correct

During ultrafiltration in the kidneys, large molecules like blood proteins and formed elements (blood cells) are normally not filtered out.

एका मिनिटात मूत्रपिंडातून किती रक्त वाहते ? How much blood flows through the kidneys per minute ?

1)1 लीटर / 1 litre✓ Correct
2)0.75 लीटर / 0.75 litre
3)0.50 लीटर / 0.50 litre
4)0.25 लीटर / 0.25 litre

Approximately 1 to 1.2 litres of blood flows through the human kidneys per minute, which accounts for roughly 20-25% of the cardiac output.

मानवाच्या शरीरातील नेफ्रॉन्स मध्ये युरीन बनविण्याचा योग्य घटनाक्रम कोणता ? In the nephron of man, what is the correct sequence of urine formation ?

1)सिलेक्टीव्ह रिअॅबसॉर्बशन, ट्युबुलर सिक्रिशन आणि अल्ट्राफिल्ट्रेशन / Selective reabsorption, tubular secretion and ultrafiltration
2)अल्ट्राफिल्ट्रेशन, ट्युबुलर सिक्रिशन आणि सिलेक्टीव्ह रिअॅबसॉर्बशन / Ultrafiltration, tubular secretion and selective reabsorption
3)अल्ट्राफिल्ट्रेशन, सिलेक्टीव्ह रिअॅबसॉर्बशन आणि ट्युबुलर सिक्रिशन / Ultrafiltration, selective reabsorption and tubular secretion✓ Correct
4)ट्युबुलर सिक्रिशन, सिलेक्टीव्ह रिअॅबसॉर्बशन आणि अल्ट्राफिल्ट्रेशन / Tubular secretion, selective reabsorption and ultrafiltration

Urine formation in nephrons involves three main steps: Glomerular filtration (ultrafiltration), Selective reabsorption, and Tubular secretion.
