Where is the kidney in men?

We all know that the internal organs of the human body are located in a vertical plane. Because the internal organs are inside the human body, if there are some problems with them, they cannot be seen with the naked eye. They need to be detected through medical examinations. So where are the kidneys of men?

The kidneys are located at the back of the waist. The right renal inguinal fossa is opposite to the transverse process of the second lumbar vertebra, and the left one is opposite to the transverse process of the first lumbar vertebra. The right kidney is 1-2 cm lower than the left kidney due to the liver. Normal renal function is within the range of 1-2 cm. The renal function is in the diaphragm. During routine physical examination, except for the lower pole of the right kidney, which can be touched at the outer edge of the ribs, the left kidney is not easy to touch.

The kidneys are located on both sides of the spine, close to the posterior abdominal wall, and behind the peritoneum. The upper end of the left kidney is level with the outer edge of the 11th lumbar vertebra, and the lower end is level with the outer edge of the 2nd intervertebral disc. The right kidney is one and a half cones lower than the left kidney. The left 12th rib passes obliquely through the middle of the back of the left kidney, and the right 12th rib passes obliquely through the upper end of the back of the right kidney.

Functions of Kidneys:

1. Converted into urine to maintain water balance. "Each kidney in the body has about 1.3 million renal tubules, which can process and clean 200 liters of blood every day, equivalent to 10 barrels of drinking water, and produce about 1.8 liters of urine. When the body has too much or too little water, the kidneys adjust urination to maintain the body's water balance."

2. Excrete compounds and toxic substances from the body. "Basic metabolism in the body produces metabolic waste, such as urea, uric acid, creatinine, etc. The kidney function is to excrete these wastes out of the body through urine, thereby maintaining normal physiological activities."

3. Endocrine effects. For example, it metabolizes erythropoietin (EPO) to promote bone marrow hematopoiesis; converts into specific vitamin D to regulate calcium and phosphorus metabolism, maintain the normal structure and function of bones; metabolizes vasoactive substances to regulate blood pressure, etc.
