Kidney physiology. In this illustration, we can observe the function of the kidneys, bilateral urinary organs with a bean-like shape. Moreover, this image shows their location in the upper right and left abdominal quadrants. Likewise, this representation highlights the processes that enable blood filtration and urine formation.
Kidney physiology focuses on the ability of the kidneys to maintain internal balance. First, the kidneys filter blood through millions of nephrons. Therefore, they remove waste products such as urea and creatinine.
In addition, during filtration, useful substances and waste are separated. Next, reabsorption occurs, where the body recovers water, glucose, and electrolytes. As a result, essential nutrients are preserved.
Then, tubular secretion takes place, adding additional substances to the urine. Furthermore, these processes help adjust the final composition of the excreted fluid.
On the other hand, the kidneys regulate water and electrolyte balance. Indeed, they control levels of sodium, potassium, and calcium. In this way, internal stability is maintained.
Moreover, the kidneys perform important endocrine functions. For example, they produce erythropoietin, which stimulates red blood cell production. They also regulate blood pressure through the renin-angiotensin system.
Furthermore, the kidneys help maintain blood pH balance. Consequently, they prevent disturbances in body acidity.
In summary, kidney physiology enables filtration, regulation, and waste elimination. Additionally, it maintains internal balance. Therefore, proper kidney function is essential for overall health and physiological stability.
