perinephric fat
The renal pyramids are located in the cortex of the kidney.
Ernest Borgnine Died Of Renal Failure In His Sleep At July 8th 2012, He Was Aged 95.
In the kidnies, they are also called renal pyramids. See also http://en.wikipedia.org/wiki/Renal_pyramid.
Formation of urine Human kidneys consist of three layers. These layers are, in order, the cortex on the outside of the organ, the medulla, and the pelvis. Blood flows into the medulla through the renal artery. In the medulla and cortex, the renal artery branches into increasingly smaller arteries. Each of these arteries ends in a blood filtration unit called a nephron. Two healthy kidneys contain a total of about 2 million nephrons, which filter about 190 litres of blood daily. A nephron consists of a network of tiny blood vessels, the glomerulus, surrounded by Bowman's capsule, a two-layer membrane that opens into a convoluted tubule. Pressure forces much of the blood plasma (fluid portion of the blood) through the glomerulus and into Bowman's capsule. The resulting tubular fluid, which contains water and dissolved chemicals, then passes into the convoluted tubule. The portion of the blood that remains in the glomerulus flows into small vessels called capillaries, which surround the convoluted tubule. As the tubular fluid flows through the tubule, substances needed by the body are absorbed by the cells of the tubule wall. These substances, which include amino acids, glucose, and about 99 per cent of the water, then rejoin the blood in the capillaries. The capillaries return the blood to the heart by way of the renal vein. Substances not absorbed in the tubule are wastes that the body cannot use. Other wastes are secreted into the tubular fluid by the tubular cells of the kidney. These various substances, which include ammonia, urea, uric acid, and excess water, make up urine. The urine passes from the convoluted tubules into larger collecting tubules and then into the pelvis layer of the kidney. A tube called the ureter carries urine from each kidney into the urinary bladder. Urine collects in the bladder until it passes out of the body through another tube, the urethra. Healthy kidneys produce from 1 to 2 litres of urine daily.
At the time, he was thought to have died of Typhoid Fever, but nowadays this is thought unlikely as he was ill for two years before his death so he may have had a long term condition such as renal failure or cancer.
from interior to exterior: fibrous capsule, perirenal fat capsule and renal fascia. :)
The tissue that covers the kidneys is a connective tissue. There are actually three layers of tissue that covers the kidneys, the renal fascia, adipose capsule, and renal capsule.
Renal fascia
renal fascia (outer layer), perirenal fat capsule, fibrous capsule (inner layer)
It's a well-defined layer of fat around the kidney, which is distinct from both the intraperitoenal fat anteriorly and the pararenal fat posterolaterally.
The fiberous capsule. The perirenal fat capsule and the renal fascia don't (so far as I am aware, anyway) specificly protect the kidney from infection.renal fascia
the medulla is organized into a GROUP of pyramids. It makes up the pyramids.
Each kidney is held in place by connective tissue, called renal fascia, and is surrounded by a thick layer of adipose tissue, called perirenal fat, which helps to protect it. A tough, fibrous, connective tissue renal capsule closely envelopes each kidney and provides support for the soft tissue that is inside.
The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla.
The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla.
The fibrous membrane immediately surrounding the kidney is called the renal capsule. It is a smooth, transparent sheath that helps to maintain the shape and protect the kidney.
