Kidney Structure
Kidney structure – including what?
Specifically, kidney structure includes : Glomeruli, renal cortex, fibrous capsule, renal medulla, renal papilla, fat in renal sinus, renal sinus, renal lobe.
Also, renal column, small sepals, large sepals, renal artery, pelvis, kidney vein, kidney pyramid in the medulla.
Moreover, analyze the internal kidney structure to see how great it is!
When cutting the kidneys vertically, you will see the color is not the same between the 2 parts.
First, the outer layer is adjacent layer, the thickness of about 0.5 ~ 1 cm, pink-brown.
You will see many small, dense grains of pink. Those are kidney units.
Soft kidney unit, evenly distributed, inside there are many special machines that make urine. In addition, also known as glomeruli.
The two kidneys have about 3 million platelet units connected to the kidneys ureter.
On the other hand, glomeruli are very small, must use a microscope to see.
Outwardly, they look like circles, but they are actually a small, zigzag network of blood vessels.
The platelets connect to 2 blood vessels, the arteries enter the bridge and the artery releases blood.
On top of that, all blood in the human body must pass through glomeruli to perform dialysis.
The inside part of the kidney is light red, 2 ~ 3 cm thick, which is renal medulla.
In it, see about 10 ~ 20 pyramidal objects close together and the bottom facing outwards, pointed tip inwards, that is renal pyramid in renal medulla.
The pointed part is renal papilla. It has about 10 ~ 30 small holes arranged like a sieve.
In particular, the urine that forms in the kidneys out through these holes.
At the exit of each renal papilla, there is a small funnel-shaped kidney disk, about 2 ~ 3 small kidney disks form a large kidney plate, which is the renal pelvis.
The kidney structure is truly marvelous – the smallest parts, but they carry out extremely important tasks.
