F. Shkrudnev N. Levashov's "SvetL Broom" in A. Khatybov's "Bath School" and A Labour Spade 297 5.8. The "SvetL" and the Kidneys A somewhat lengthy deviation does not negate the necessity to make clear what we started with – the excretory system. The kidneys are a pair of beanlike formations about 10 cm long, lying on either side of the midline of the posterior wall of the abdominal cavity, just below the stomach level. On the inner, concave side of each kidney, there is a funnel-shaped chamber called the renal pelvis. Urine, which is continuously drop by drop, the kidneys excretes, is collected in the pelvis and flows down the urethra, being pushed not by peristaltic contractions of its walls, as is customary in the modern sense, but by electromagnetic waves, into the bladder – a hollow muscular organ located in the lower abdomen. The muscle walls of the bladder relax and stretch, making room for urine as it accumulates. The pH of the medium in the bladder is such that any bacterium can be in this medium for a fraction of a second. As the volume of urine in the bladder increases, stretching the muscle walls stimulates the nerve endings that are in them, which send impulses to the brain that cause a sense of filling. To make it possible to urinate, the impulses coming from the brain cause the bladder contraction and a relaxation of the sphincter closing the opening from the bladder to the urethra. Here I note that the maximum pressure that the kidney can sustain is 235/210 , while the pressure in the Brain vessels can be up to 255/235. The combination of three processes – filtration, reabsorption (reverse suction) and tubular secretion, – allows the kidneys to remove waste, but retain useful components of the blood. On its further way from the renal pelvis through the urethra, bladder and urinating canal urine does not undergo any changes. The changes in the concentration of substances occur when the filtrate passes from the Bowman capsules through the long sinuous tubules into the collecting tube. The walls of the renal tubules consist of a
