If you are speaking at the Society for Nephrology meeting, you probably don’t have to explain what a glomerulus is or convince them that its study is important for understanding kidney function.
Enteropneusta called the glomerulus, a vascular complex placed on either side of the anterior portion of the stomochord, projecting into the proboscis-coelom.
The glomerulus is a lobulated net-work of convoluted capillary bloodvessels, held together by scanty connective tissue.
A glomerulus is a capillary tuft surrounded by Bowman's capsule in nephrons of the vertebrate kidney.
This results from the large amount of blood flow through the glomerulus, the relatively large pores (40 angstrom, an angstom is one one-hundred millionth of a centimeter) in the glomerular capillaries, and the hydrostatic pressure of the blood.
Filtration, the first process, takes place in the glomerulus, the very vascular beginning of the nephron.
Both lipid-soluble and polar substances will pass through the glomerulus into the tubule filtrate.
The nephron has three primary regions that function in the renal excretion process, the glomerulus, proximal tubule, and the distal tubule.
Small toxicants (both polar and lipid-soluble) are filtered with ease by the glomerulus.
The presence of albumin in the urine indicates that the glomerulus filtering system is damaged letting large molecules pass through.
