Morcellation devices in surgery. Laparoscopic morcellation is commonly used at surgery to remove bulky specimens from the abdomen using minimally invasive techniques. Historically, morcellation was performed using a device that required the surgeon or assistant to manually 'squeeze' the handle.
Endocrine functions of the kidneys. The kidneys produce three important hormones: erythropoietin, calcitriol (1,25- dihydroxycholecalciferol) and renin. They also synthesize prostaglandins, which affect many processes in the kidneys.
Each kidney in a human contains about a million nephrons. These nephrons make the actual changes to the blood composition.There are two types of nephron: cortical nephron and juxtamedullary nephron. The main difference in the two types of nephron is the length to which the loop of Henle extends into the kidney.Cortical nephron, which are about eighty percent of the nephron in humans, have a loop of Henle that does not extend past the cortex of the kidney.ach kidney in a human contains about a million nephrons. These nephrons make the actual changes to the blood composition.
