Transitional epithelium Pelvis Central collecting system of kidney. •Trace blood flow through the kidney. Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. The Excretory System is defined as a biological system that helps in the elimination of the nitrogenous waste products of metabolism and also helps in maintaining homeostasis in our body.. Excretory Organs in Different Organisms. These narrow tubes carry urine from the kidneys to the bladder. However, there are additional, equally important functions played by the system. The Urinary System Chapter 26 The organs of the urinary system include: Functions of the urinary system (all done by kidneys): Regulate the volume, concentration, pH and content of blood Eliminate metabolic wastes as urine 3 processes occur within the kidneys to accomplish these goals Blood vessels (capillaries) Renal tubules R Reabsorption (R) - Movement (by passive & active means) of most .

Anatomy of the urinary System kidneys -a pair of bean -shaped organs located retroperitoneally , responsible for blood filtering and urine formation. •Identify and differentiate between the portions of the nephron. The apex of each pyramid (renal papilla) opens medially to the minor calyx, which is the first part of the urinary collecting system within the kidney. The papillae are bundles of collecting ducts that transport urine made by nephrons to the calyces of the kidney for excretion. The _____ is located at the hilus? Since the male and female urethras are different, be sure you examine models with both male and female genitalia. This artery divided into cranial and caudal branches in 85 cases (93.4%). These alterations pertain primarily to reabsorption and secretion of electrolytes, acid, and water. Complete the labeling of the diagram to correctly identify the urinary system organs.
