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.
Humans have two kidneys and each kidney is supplied with blood from the renal artery. The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. This is done with the help of millions of nephrons present in the kidney.
