What are the histological features of the urinary system?
The renal cortex contains most of the glomeruli and numerous cross sections of the tubules. The nephron tubules are made of simple cuboidal epithelium. A distinct, often visible on the histological sections, basement membrane surrounds each tubule.
What is urinary system PDF?
The Urinary System The urinary system’s function is to filter blood and create urine as a waste by-product. The urinary system organs include the two kidneys, renal pelvis, two ureters, bladder, and urethra.
What is the histology of the urinary bladder?
The microscopic structure of the urinary bladder wall organizes into the following layers from inside out. Lining epithelium: The urinary bladder lining is a specialized stratified epithelium, the urothelium. The urothelium is exclusively in urinary structures such as the ureter, urinary bladder, and proximal urethra.
What is the histology of the ureters?
The ureter (one per kidney) is a long, straight, muscle-walled tube. The epithelium lining this tube is stratified, transitional epithelium.
What are the important histological parts of the kidney?
Kidney structure.
What type of tissue is in the urinary system?
epithelium
Urinary bladder and urethra are consisting of epithelium on the lumen surrounded by a collagen rich connective tissue and muscle layer. The epithelial layer serves as a barrier that prevents the urine from sweeping into the body cavity.
What are the main components of the urinary system?
The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra. The body takes nutrients from food and converts them to energy. After the body has taken the food components that it needs, waste products are left behind in the bowel and in the blood.
What histological features form the filtration membrane?
This unique filtration barrier contains three histological structures: the capillary endothelium of the glomeruli, specialized cells called podocytes, and the fused basement membranes of both of these cells (FIG 1).
What are the 4 major structures of the urinary system?
The urinary system’s function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.
Which epithelium is found in urinary system?
There are three types of epithelial cells that line the urinary tract. They are called transitional cells, renal tubular cells, and squamous cells. If there are squamous epithelial cells in your urine, it may mean your sample was contaminated.
What are the three layers of the filtration membrane?
Glomerular filtration barrier showing three distinguished layers: Fenestrated endothelial cells, glomerular basement membrane and podocytes.
What tissues are in the urinary system?
Urinary bladder and urethra are consisting of epithelium on the lumen surrounded by a collagen rich connective tissue and muscle layer. The epithelial layer serves as a barrier that prevents the urine from sweeping into the body cavity.
