Do you Know your Kidneys Matter?


Our bodies are dependent on our internal organs to survive and reproduce. Each organ is associated with the other for survival. The brain, the liver, the lungs, the kidneys, the bladder, the heart, the stomach and the intestines perform their respective functions to ensure proper functioning of the body system.
Kidneys, on a daily basis, excellently maintains a chemical balance in the body. The human body needs to maintain a chemical balance in order to prevent chronic illness and other anomalies that may affect other organs.
Kidneys are positioned at the back of the abdominal cavity. They execute some vital functions in the human body such as the formation of urine, balancing chemicals and fluids in the body, and extracting waste from the bloodstream. They also aid various other organs in carrying out routine functions in the body. Let’s discuss the functions of the kidney.

Functions of the Kidneys

Blood Pressure Regulation

Kidneys produce a vessel-constricting protein called angiotensin, which regulates blood pressure and signal the body to retain water and sodium. In case the blood pressure drops, kidneys immediately exercise the function of increasing it.

Waste Excretion

The human body accumulates harmful elements such as toxins, urea and excess salts over time. Kidneys facilitate the excretion of these harmful elements by filtering the bloodstream.

Maintain Water Levels

Kidneys adjust their function to the level of water intake. When water intake drops, kidneys ensure that water Is retained in the body instead of flushing it through urine.

Acid Regulation

The body’s internal environment can get acidic if the kidneys do not properly perform their balancing function. Kidneys filter out toxins and metals that can cause an increase in acidity level.

Red Blood Cell Stimulation

Kidneys require proper oxygenation to keep up their activity. In case of oxygen, deficiency kidneys release erythropoietin which stimulates the bone marrow and increases the production of red blood cells. Kidney health cannot be overemphasized, as it is extremely important to the human body. Now let’s talk about foods that are beneficial to the kidney.
