We kidneys are vital organs in the retroperitoneal space, • The right kidney is lower, displaced by the liver’s base, • 11 cm long, a fifth of cardiac output we receive, • We filter blood and make urine, till your bladder you relieve! • We are encased in several layers of fascia and fat, • There’s a tough fibrous layer, the renal capsule, right off the bat, • Then the perirenal fat, or adipose capsule of the kidney, • Which provides us with protection from physical injury. • Then the renal fascia which enclose, the kidneys and adrenal glands, • and the pararenal fat behind us, remember for exams! • From the abdominal aorta branch the paired renal arteries, • Sending us blood from the heart, in large quantities! • The blood leaves the kidneys, through renal veins, these two! • The hilum lets blood vessels, nerves, and the ureter pass through! • Hilar fat and lymphatic tissue, enclose your ureter and vessels, • And a fat-filled cavity, the renal sinus, next to hilar fat nestles. • The renal sinus contains the renal pelvis and calyces, • And separates the renal medullary tissue from these. • The kidney’s functional substance is the kidney parenchyma, • Made up of the renal cortex, and the renal medulla! • An adult human kidney, typically will enclose, • Around 7-18 cone-shaped renal lobes! • Each with renal cortex surrounding a renal pyramid, • Which is a portion of the renal medulla, remember, kid! • Between pyramids are renal columns - medullary extensions • of the renal cortex, which is anchored through these suspensions! • Each renal pyramid’s apex, or renal papilla, connects, • Draining into a minor calyx, which urine production collects. • Several minor calyces merge to form major calyces, • which pass urine to the flat and funnel-shaped renal pelvis. • The urine drains from the renal pelvis to the ureter, • Which passes along the urine to be stored in the bladder! • We each have a million nephrons, our structural and functional units, • At the nephron’s start, filtration occurs in the glomerulus • Spanning the cortex and medulla, nephrons bear the burden, • Of filtration, reabsorption, secretion, and excretion to produce urine! • Kidneys control the volume of various body fluid compartments, • Help regulate blood pressure, and remove toxins of all assortments. • We excrete metabolic waste and control electrolyte concentrations, • Expelling hydrogen, ammonium, potassium in our secretions. • Other secretions into urine include urea, from protein catabolism, • And uric acid, from nucleic acid metabolism. • But water, sodium, glucose, amino acids and bicarbonate, • Are reabsorbed into the body, not released when you urinate! • Some other kidney functions on the nephron don’t depend, • Like synthesizing hormones, erythropoietin and renin. • Music/Lyrics/Visual © Neural Academy • 3D Models from: • https://www.turbosquid.com/FullPrevie... • https://www.turbosquid.com/3d-models/... • https://www.turbosquid.com/FullPrevie...
