Listeriosis is a bacterial infection caused by Listeria monocytogenes. While many bacteria generally infect specific locations within the human body, Listeria may infect many different sites, such as the brain or spinal cord membranes or the bloodstream.
The glomerulus is a tuft of small blood vessels called capillaries located within Bowman's capsule within the kidney. Between the capillaries and Bowman's capsule lies mesangium.Blood enters the capillaries of the glomerulus by a single arteriole called an afferent arteriole and leaves by an efferent arteriole. glomerulus is a network (as a tuft) of capillaries located at the beginning of a nephron in the kidney. It serves as the first stage in the filtering process of the blood carried out by the nephron in its formation of urine.
The cortex is the superficial outer layer of the kidney located underneath the capsule. The medulla is the inner layer and it extends from the renal cortex to the renal sinus. The medulla is divided into various cone-shaped structures called the renal pyramids.tructures such as the renal veins, artery, nerves and lymphatic vessels are located in the renal hilum. The renal sinus is a fat-filled cavity inside the kidney that extends from the hilum. At the hilum the ureters also exit the kidney. The kidney is covered by a fibrous renal capsule.
