ЛЕКЦИЯ № 45. The kidneys function
The kidneys are filters which remove waste products from the blood. In the human each is a bean-shaped organ, some four inches long and about two inches wide. The two are situated high up on the posterior abdominal wall behind the peritoneum and in front of the lats ribs and the upper two lunbar transverse processes. Each is invested by a fibrous capsule surrounded by more or less perinephric fat. On the upper pole of each is a supra-renal gland. On the medical side is a notch called the hilum where the vessels and the ureter are attached.
Vertical selections through a kidney discloses three more or less concentric zones. The other light-colored zone is the renal cortex, within this is the darker renal medulla and within this again is a space – the renal sinus which is normally occurred by a fibrous bag called the renal pelvis. The pelvis opens below into the ureter. The cortex extends inwards in a series of renal columns which divide the medulla into a number of renal pyramids. Each pyramid has a free rounded projection – a renal papilla – which lies in a cap – like extension, of the pelvis cal led a renal calyx. The pelvis is lined by transitioual epithelium, which extends the calyces and covers the papillae.
