Urinary System. Identify the kidney, ureter, and urinary bladder microscopically. Distinguish between the cortex and medulla of the kidney. Identify the segments of the nephron, ie, the proximal tubule, distal tubule, and Bowman's capsule with the glomerulus and the loop of Henle. Identify medullary rays, distinguishing them from other regions of the kidney cortex.

The renal structures that conduct the essential work of the kidney cannot be seen by the naked eye. Only a light or electron microscope can reveal these structures. Even then, serial sections and computer reconstruction are necessary to give us a comprehensive view of the functional anatomy of the nephron and its associated blood vessels. Nephrons take a simple filtrate of the blood and modify it into urine. Many changes take place in the different parts of the nephron before urine is created for disposal. The term forming urine will be used hereafter to describe the filtrate as it is modified into true urine. The principle task of the nephron population is to balance the plasma to homeostatic set points and excrete potential toxins in the urine.

Pre-Lab Reading Introduction The urinary system is comprised of the kidney, ureter, urinary bladder, and urethra.

The essential tissue composition of kidney is that of a gland with highly modified secretory units and highly specialized ducts. Kidneys excrete urine, produced by modifying a filtrate of blood plasma. Click here or scroll down to continue this introduction to kidney. To go directly to specific topics, see the table below.

The urinary system consists of the paired kidneys and ureters, the bladder, and the urethra. This general role of the kidneys involves a complex combination of renal functions:. Regulation of the balance between water and electrolytes inorganic ions and the acid-base balance;. Excretion of many bioactive substances, including many drugs;. Secretion of renin , a protease important for regulation of blood pressure by cleaving circulating angiotensinogen to angiotensin I;.

A renal corpuscle is the blood-filtering component of the nephron of the kidney. It consists of a glomerulus - a tuft of capillaries composed of endothelial cells , and a glomerular capsule known as Bowman's capsule. The renal corpuscle is composed of two structures, the glomerulus and the Bowman's capsule. Endothelial cells, which have large fenestrae , are not covered by diaphragms. Mesangial cells are modified smooth muscle cells that lie between the capillaries.

The kidneys are located at the rear wall of the abdominal cavity and they are protected by the ribcage. The kidneys are the primary functional organ of the renal system. They are essential in homeostatic functions such as the regulation of electrolytes, maintenance of acid—base balance, and the regulation of blood pressure by maintaining salt and water balance. They serve the body as a natural filter of the blood and remove wastes that are excreted through the urine. They are also responsible for the reabsorption of water, glucose, and amino acids, and will maintain the balance of these molecules in the body. In addition, the kidneys produce hormones including calcitriol, erythropoietin, and the enzyme renin, which are involved in renal and hemotological physiological processes.
