Renal system
The Renal System Kidneys – collect the body’s waste products and Ureters – Muscular tubes that transport urine from each kidney to the bladder. Urinary Bladder – A sac that collects and holds urine that comes from the ureters. Urethra – a narrow passageway where urine passes from the bladder to the outside of the body, called urination. Kidney Anatomy Renal Capsule – outer membrane that surrounds the kidney; it is thin but tough and fibrous Renal Pelvis – basin-like area that collects urine from the nephrons, it narrows into the upper end of the ureter Calyx – extension of the renal pelvis; they channel urine from the pyramids to the renal pelvis Cortex – the outer region of the kidney; extensions of the cortical tissue, contains about one million blood filtering nephrons Nephron – these are the filtration units in the kidneys Medulla – inner region of the kidney contains 8-12 renal pyramids. The pyramids empty into the calyx. Medullary pyramids – formed by the collecting ducts, inner part of the kidney Ureter – collects filtrate and urine from renal pelvis and takes it to the bladder for urination Renal Artery – branches off of the aorta bringing waste-filled blood into the kidney for filtering in the nephrons; the renal artery is further subdivided into several branches inside the kidney. Each minute, the kidneys receive 20% of the blood pumped by the heart. Some arteries nourish the kidney cells themselves. Renal Vein – removes the filtered blood from the kidneys to the inferior vena cava.
