The bladder expands like an elastic sac to hold more urine. Deamination converts the amino (NH2) groups into ammonia (NH3), ammonium ion (NH4+), urea, or uric acid (Figure 15.9). Urine produced in the kidneys travels down the ureters into the urinary bladder. As the glomerular filtrate progresses through the nephron, these capillary networks recover most of the solutes and water, and return them to the circulation.

It promotes the recovery of water, decreases urine volume, and maintains plasma osmolarity and blood pressure. . Diurnal (daytime) incontinence is usually not diagnosed until age 5 or 6. Take, for example, regulation of pH, a function shared with the lungs and the buffers in the blood. In the male, the urethral opening is on the under surface of the penis. [Return to Figure 15.2]. blood enters the kidney through this and flows into the nephrons. This is the only portal system in which an arteriole is found between the first and second capillary beds. biology.

The ureters are approximately 30 cm long. The kidneys lie on either side of the spine in the retroperitoneal space between the parietal peritoneum and the posterior abdominal wall, well protected by muscle, fat, and ribs. (n.d.-a). There is also an opposing force, the osmotic pressure, which is typically higher in the glomerular capillary. They then hold the urine as long as they can and, when they can hold it no longer, start to urinate and then stop and start the urine stream. The renal arteries form directly from the descending aorta, whereas the renal veins return cleansed blood directly to the inferior vena cava. A rare type of malignant tumor of the kidney that occurs in young children. Bladder function has a storage phase and a voiding phase.
