THE IMPORTANCE OF KIDNEY AND KIDNEY FUNCTION IN THE BODY

KNOW THE IMPORTANCE OF KIDNEY AND KIDNEY FUNCTION IN THE BODY

Kidneys play key roles in body function, not only by filtering the blood and remove waste products, but also with balance electrolyte levels, electrolyte in the body, controlling blood pressure, and stimulates the production of blood cells red.
Kidneys are located in the abdomen to the back, normally one at each side of the spine (vertebrae). They get their blood supply through the renal arteries directly from the aorta and send the blood back to the heart via renal veins into the cava vein. The term "renal" comes from the Latin name for the kidney.

Kidneys have the ability to monitor the amount of body fluids, concentrations of the electrolyte-electrolytes such as sodium and potassium, and acid-base balance of the body. They filter waste products of metabolism, such as urea from protein metabolism and uric acid from the description of DNA. Two waste products in the blood can be measured: blood urea nitrogen (BUN) and creatinine (Cr).
When blood flow to the kidneys, the sensors in the kidney decide how much water out as urine, along with what the concentration of the electrolyte-electrolyte. For example, if a person is dehydrated from exercise or from a disease, kidneys will hold as much water and the urine becomes very concentrated. When the adequacy of water present in the body, urine is much more dilute, and the urine becomes clear. This system is controlled by renin, a hormone produced in the kidney that are part of the regulatory systems and fluid from the body's blood pressure.

Kidney is also a source of erythropoietin in the body, a hormone that stimulates the bone marrow to make blood cells red. Specialized cells in the kidney that monitors the concentration of oxygen in the blood. If oxygen levels fall, erythropoietin levels rise and the body begins to make more blood cells red.

After the kidneys filter the blood, urine excreted through the ureter, a thin tube which connects the bladder. He then stored in the bladder urinate wait (urine), when the urinary bladder sends out from the body through the urethra.
