Urine flows from kidney to the urinary bladder through ureters. Urinary bladder collects and from urinary bladder it goes outside the body through urethra
the urinary bladder.
Water
In fact, the kidney dose not receives the urine but it produces the urine by receiving the filtrate from the blood vessels . and the first part wich receives the filtrate is the " glomerus"
The glomerulus filtrate is located within the Bowman's capsule, which is the initial part of the kidney tubule where the glomerular filtrate is collected before being processed further in the renal tubules.
The Glomerular Filtration Rate
The filtrate.
Conditions which allow the red blood cells and protein to enter the filtrate are renal infections, kidney infections, diabetes, hypothyroidism, jaundice, and Glomerulonephritis. The reasons of red blood cells entering the filtrate can be various and dangerous.
Secretion of substances into the filtrate occurs primarily in the distal convoluted tubule and the collecting duct in the nephron of the kidney. This process helps in regulating the composition of the urine by removing additional substances from the blood and adding them to the filtrate for excretion.
The macula densa cells located in the distal convoluted tubule of the kidney are chemoreceptors that respond to changes in solute content of the filtrate. These cells are sensitive to the concentration of sodium and chloride ions in the filtrate, signaling the juxtaglomerular cells to regulate blood pressure and filtration rate accordingly.
