The kidneys, ureters, bladder, and urethra are all part of the urinary system. This system removes waste and excess water from your blood. Urine is formed from this waste.
1. Kidney – In the urinary system, the kidneys are two bean-shaped organs. They assist the body in excreting waste through urine. They also aid in the filtering of blood before it is returned to the heart. The kidney’s parenchyma is epithelial tissue (renal tubules and corpuscles).Â
2. Ureter – The ureter is a tube that connects the kidney to the urinary bladder and transports urine. Each kidney has two ureters, one for each kidney. The ureter’s wall is made up of three layers. The fibrous coat, or outer layer, is a fibrous connective tissue supporting layer. Inner circular and outer longitudinal smooth muscle make up the muscular coat, the middle layer. Peristalsis is the major function of this layer: it propels urine.
3. Urinary Bladder – The urinary bladder serves as a temporary urine storage reservoir. The size and form of the urinary bladder vary depending on how much urine it holds and how much pressure it receives from other organs. Transitional epithelium tissue lines the urinary bladder and can expand extensively to handle huge amounts of urine. The underlying tissues are likewise protected by the transitional epithelium from acidic or alkaline urine.
