human kidney are small in size paired bodies with dark red color and thick consistency.Its shape they resemble beans.It should be noted that with their upper ends closer together up to about 8 cm, but lower on the contrary, are spaced from each other by 11 cm.
human kidney which arrangement symmetrically located in the lumbar zone.More specifically, on both sides of the spine in the region XII breast (at its level), and two upper lumbar vertebrae.Kidney located closer to the rear of the belly wall, namely the inner surface thereof.
concave inner edge of the kidney in the middle of a certain niche.It is aimed directly towards the spine.And the outer edge of it - more convex.Naturally, human kidney in contact with the abdominal organs.And, in addition, for each of them on top of adjacent adrenal gland, which is enclosed with the kidney in some fat capsule.
It should be noted that the left kidney is slightly higher than the right.This is mainly due to the fact that the right side of a lot of space occupies a body such as the liver.Rather, it is for this reason that the right kidney is thicker and shorter compared to the left.
In the center of the concave edge has a slight indentation, called the renal gate.This name is obtained from the fact that it is traversed by all outgoing and incoming of organ renal nerves, blood vessels and ureter.
On its outer walls of the human kidney surrounded by a pretty thick layer of fat (it is precisely the fat capsule that connects the kidney with the adrenal gland).With this capsule and renal fascia (its singular outer shell) kidneys and are retained in place, locking in its normal position.
Therefore, if there is a rapid and dramatic weight loss, in which respectively involved and fatty tissue directly renal capsule, then the kidney may be easy enough to get out of this standstill.It threatens that the kidney may be displaced or somewhat down or start an unpredictable movement in any direction.
As a result - a lot of discomfort from their host.In medicine it is an unhealthy state is defined as the omission of the kidney, and its extreme manifestation - as a floating kidney.
human kidney is the most important organ of the urinary system.Usually, when a person inhales or change the position of his body from horizontal to vertical, the kidneys are shifted by about 3-5 cm from top to bottom.Then they can test the lower pole of the left hand and the right upper quadrant.
main functions that perform the kidneys in the human body are:
- regulation of water-salt balance of the whole body, they maintain the necessary concentration of salts, and volumes of fluids in the human body;
- excretion of toxic (harmful) and unwanted substances from the body;
- regulation of blood pressure.
human kidney size varies between 10-12 cm x 4-5 cm. These relatively small bodies by filtering the blood, producing urine.She, in turn, going to the cavity system is displayed in the ureter, the bladder, and then - out.
In normal kidney function passes therethrough all the blood circulating in the body for about three minutes.In one minute the glomerulus filters the 70 to 100 ml urine primary, which then concentrates in the renal tubules.So, one day in an adult should be allocated 1-1.5 liters of urine (it's less than 350-500 ml of the liquid rules, which he drank).
If there is a prolonged disturbance of outflow of urine is directly from the cavity system of the kidneys, it can damage the fabric and its serious violation of its functions.
