    Unitatea structurală şi funcţională a rinichiului este:

    • Nefronul

    • Neuronul

    • Piramida renală

    • Ureterul

    Correct Answer
    A. Nefronul
    Explanation
    The correct answer is "nefronul" (the nephron). The nephron is the structural and functional unit of the kidney. It is responsible for filtering the blood and producing urine. Each kidney contains millions of nephrons, which consist of a renal corpuscle and a renal tubule. The renal corpuscle filters the blood, while the renal tubule reabsorbs useful substances and excretes waste products. Therefore, the nephron plays a crucial role in maintaining the body's fluid balance and eliminating waste.

    Căile urinare extrarenale sunt:

    • Uretere, vezica urinară, anus

    • Uretra, vezica urinară, bazinet

    • Uretere, vezica urinară, uretra

    • Calice, bazinet, uretra

    Correct Answer
    A. Uretere, vezica urinară, uretra
    Explanation
    The correct answer is "uretere, vezica urinară, uretra." The question asks for the extrarenal urinary pathways, which refers to the structures outside of the kidneys. The ureters are the tubes that connect the kidneys to the bladder, allowing urine to flow from the kidneys to the bladder. The bladder is a muscular organ that stores urine until it is expelled through the urethra, which is the tube that carries urine from the bladder to the outside of the body. Therefore, the correct answer includes all three structures that are part of the extrarenal urinary pathways.

    Ultrafiltrarea glomerulară se realizează la nivelul:

    • Tubului contort distal

    • Tubului contort proximal

    • Tubului colector

    • Corpusculului renal

    Correct Answer
    A. Corpusculului renal
    Explanation
    Ultrafiltrarea glomerulară se realizează la nivelul corpusculului renal. Acesta este format din glomerulul renal și capsula Bowman, care împreună formează unitatea de bază a rinichiului responsabilă de filtrarea sângelui. Glomerulul renal are o structură specializată care permite trecerea substanțelor din sânge în capsula Bowman, iar acest proces de filtrare este cunoscut sub numele de ultrafiltrare glomerulară. Tubulii contorți distal și proximal, precum și tubulul colector, sunt implicați în reabsorbția și secreția substanțelor filtrate în urină.

    Rate this question:

  • 8. 

    Ultrafiltrarea glomerulară constă în:

    • Trecerea plasmei sanguine prin membrana filtranta în tubul urinifer

    • Trecerea elementelor figurate din glomerul in capsul Bowman

    • Trecerea apei din tubii uriniferi in capilarele peritubulare

    • Trecerea sangelui din capilarele peritubulare in tubii uriniferi

    Correct Answer
    A. Trecerea plasmei sanguine prin membrana filtranta în tubul urinifer
    Explanation
    Ultrafiltration in the kidney occurs in the glomerulus, where blood plasma is filtered through the glomerular membrane into the tubules of the nephron. This process separates waste products, ions, and small molecules from the blood, which then continue to be processed and eventually excreted as urine. The passage of formed elements (such as red and white blood cells) from the glomerulus into Bowman's capsule does not occur during ultrafiltration. Similarly, the movement of water from the tubules into the peritubular capillaries and the movement of blood from the peritubular capillaries into the tubules are not part of the process of ultrafiltration.

    Rate this question:

  • 9. 

    In urma procesului de ultrafiltrare se formează:

    • Urina primara - 180l/24h

    • Urina finala - 120ml/min

    • Urina finala - apa si 5% substante dizolvate

    • Ultrafiltratul glomerular ce contine elemente figurate

    Correct Answer
    A. Urina primara - 180l/24h
    Explanation
    During the process of ultrafiltration, the kidneys filter the blood and produce a primary urine. The given answer states that the primary urine produced is 180 liters per day. This means that the kidneys filter a large volume of fluid from the blood, which is then further processed to produce the final urine.

    • Glomerul si tub contort distal

    • Tub contort proximal si tub contort distal

    Correct Answer
    A. Glomerul vascular şi capsula Bowmann
    Explanation
    The correct answer is "glomerul vascular şi capsula Bowmann." The renal corpuscle is composed of the glomerulus and Bowman's capsule. The glomerulus is a network of tiny blood vessels where filtration of blood occurs, and Bowman's capsule surrounds the glomerulus, collecting the filtrate. Together, they form the initial part of the nephron, which is responsible for filtering waste products from the blood in the kidneys.

    Tubul urinifer est format din:

    • Capsul Bowmann, tub contort distal si tub contort proximal

    • Tub contort proximal, ansa Henle şi tub contort distal

    • Tub contort proximal si tub colector

    • Capsula Bowmann si tub colector

    Correct Answer
    A. Tub contort proximal, ansa Henle şi tub contort distal
    Explanation
    The correct answer is "tub contort proximal, ansa Henle şi tub contort distal." This is because the tubul urinifer, or the renal tubule, is composed of the proximal convoluted tubule, the loop of Henle, and the distal convoluted tubule. These structures are all part of the nephron, which is the functional unit of the kidney responsible for filtering and reabsorbing substances from the blood to form urine. The proximal convoluted tubule is the first segment of the renal tubule, followed by the loop of Henle, which is divided into the descending and ascending limbs, and finally the distal convoluted tubule.
