1 Strenuous exercise, such as running a marathon, can also cause blood in the urine. 2  White blood cells may be a sign of infection or kidney disease. 3  Casts. 4  Some types of kidney disease can cause plugs of material (called casts) to form in tiny tubes in the kidneys.
A loop of Henle can be found in one of the hundreds of thousands of nephrons contained within the kidneys. The loop of Henle dips down from the nephron into the medulla and then back into the cortex. The loop of Henle is part of a nephron, a tiny tube inside the kidneys that filters solutes. The loop of Henle allows the kidneys to maintain the correct balance of water in the body.
What is Nephron and function. Nephron-The microscopic functional unit of the kidney. Each kidney contains more than a million nephrons, each of which extends from the renal cortex into the renal medulla in fairly linear fashion.ifferent portions of the loop of Henle reabsorb sodium, potassium, chloride, magnesium, calcium, and water. The loop of Henle plays a significant role in the concentration and dilution of the URINE, and is the target of some types of diuretic medications.
