Urinary System Explained (English)

The urinary system consists of two kidneys, two ureters, two sphincter muscles, the bladder, bladder nerves, and the urethra.

The primary function of the urinary system is to regulate and maintain the composition and volume of body fluids. The ultimate goal of the urinary system is to keep these fluid levels within normal limits, which will vary depending on the fluid. A component of this function is to help the body eliminate waste products accumulated due to cellular metabolism. Because of this vital function, the urinary system is often referred to as the excretory system.

However, it may not be prudent to call it the excretory system. Other organs besides the urinary system also play a role in excretion. The respiratory system, for example, includes the lungs, which get rid of waste products such as water and carbon dioxide. The skin is an organ that excretes waste products through sweat glands, and the liver excretes bile pigments that come from the destruction of hemoglobin. However, overall, the urinary system is primarily responsible for waste elimination. If this system fails, other organs will be unable to compensate for the accumulation of toxins.

The urinary system regulates the amount of water released in urine in order to maintain adequate fluid levels in the body. Other functions of the urinary system include regulating electrolyte concentrations in body fluids, maintaining a normal pH level in the blood, regulating blood pressure, and assisting with the release of the enzyme renin.

The urinary system also helps control red blood cell production by releasing erythropoietin, a hormone produced by the kidneys.

Sistema Urinario Explicado (Español)

El sistema urinario consta de dos riñones, dos uréteres, dos músculos del esfínter, la vejiga, los nervios de la vejiga y la uretra. La función primaria del sistema urinario es regular y mantener la composición y el
volumen de los fluidos corporales. El objetivo final del sistema urinario es mantener estos niveles de líquido dentro de los límites normales, que variarán dependiendo del líquido. Un componente de esta función es ayudar al cuerpo a eliminar los productos de desecho acumulados a causa del metabolismo
celular. Debido a esta función vital, con frecuencia se le conoce al sistema urinario como el sistema excretor.


Sin embargo, puede que no sea prudente llamarlo el sistema excretor. Otros órganos aparte del sistema urinario también juegan un papel en la excreción. El sistema respiratorio, por ejemplo, incluye los pulmones, que se deshacen de productos de desecho como agua y dióxido de carbono. La piel es un órgano que excreta productos de desecho a través de las glándulas sudoríparas, y el hígado excreta pigmentos biliares que provienen de la destrucción de la hemoglobina. Sin embargo, en general, el sistema urinario es el mayor responsable de la eliminación de productos de desecho. Si este sistema falla, los otros órganos serán incapaces de compensar la acumulación de toxinas.

El sistema urinario regula la cantidad de agua que se libera en la orina con el fin de mantener niveles adecuados de líquido en el cuerpo. Otras funciones del sistema urinario incluyen regular las concentraciones de electrolitos en los líquidos del cuerpo, mantener un nivel normal de pH en la sangre, regular la presión arterial, y ayudar con la liberación de la enzima renina.

El sistema urinario también ayuda a controlar la producción de glóbulos rojos
liberando eritropoyetina, una hormona producida por los riñones.
