What is the histology of 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 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.
What is histology of kidney?
Each kidney consists of a cortex, medulla and calyces. The nephron is the main functional unit of the kidney, in charge of removing metabolic waste and excess water from the blood.
What are the 4 main structures of the urinary system?
The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.
What type of tissue forms the lining of the urinary bladder?
The inner lining of the urinary bladder is a mucous membrane of transitional epithelium that is continuous with that in the ureters. When the bladder is empty, the mucosa has numerous folds called rugae. The rugae and transitional epithelium allow the bladder to expand as it fills.
What type of epithelium is in urethra?
The bulbomembranous and proximal portion of penile urethra is lined by stratified or pseudostratified columnar epithelium, whereas the distal penile urethra, including the fossa navicularis, is lined by stratified nonkeratinizing squamous epithelium.
What are the 7 functions of the urinary system?
Balance the body’s fluids. Balance a variety of electrolytes. Release hormones to control blood pressure. Release a hormone to control red blood cell production.
What are the types of histology?
Although one may divide microscopic anatomy into organology, the study of organs, histology, the study of tissues, and cytology, the study of cells, modern usage places all of these topics under the field of histology….Plant tissue classification
- Dermal tissue.
- Vascular tissue.
- Ground tissue.
- Meristematic tissue.
What are the common diseases of the urinary system?
Renal Disease and Failure. Renal failure uremia is a syndrome of renal failure characterized by elevated levels of urea and creatinine in the blood.
What is the main function of the urinary system?
One of the major functions of the Urinary system is the process of excretion. Excretion is the process of eliminating, from an organism, waste products of metabolism and other materials that are of no use. The urinary system maintains an appropriate fluid volume by regulating the amount of water that is excreted in the urine.
What are the parts and functions of the urinary system?
Two ureters. These narrow tubes carry urine from the kidneys to the bladder.
What is the anatomy and physiology of the urinary system?
The urinary tract is the body’s drainage system for removing urine, which is composed of wastes and extra fluid. In order for normal urination to occur, all body parts in the urinary tract need to work together in the correct order. Kidneys. The kidneys are two bean-shaped organs, each about the size of a fist.
