Part of Filtration Barrier

Followings are Part of Filtration Barrier

Question: Followings are Part of Filtration Barrier a) Endothelial Cells b) Glomerular Basement Membrane c) Bowman’s Capsule d) Renal Capsule e) Mesangial Cells Answer hint: When a substance has passed through the glomerular capillary endothelial cells, Glomerular basement membrane and podocytes, then it enters the lumen of the tubules and it is known as glomerular filtrate. Podocytes are sometimes considered as a visceral layer of

Regarding Glomerulus

Question: Regarding Glomerulus a) is a small tuft of capillaries b) contains podocytes c) covered with diaphragm d) small fenestrae of endothelial cell e) contains mesangial cells Answer hint: Glomerulus is a small tuft of capillaries. Glomerular epithelial cells podocytes put out the long foot process which interdigitate with those of adjacent epithelial cells. Glomerular capillary endothelial cells contain pores. These pores are called fenestrae. They are

Regarding Erythropoietin

Question: Regarding Erythropoietin a) Released from Mesangial cells b) Released from Interstitial Peritubular cells c) is a glycoprotein d) released from macula densa e) Released from JG cells Answer hint: Erythropoietin is produced by interstitial peritubular cells in response to hypoxia. It is also produced in perisinusoidal cells in the liver. It is a glycoprotein. Erythropoietin is released fro 1) Kidney (85%) 2) Liver (15%) 3) Spleen

Regarding Renin

Question: Regarding Renin a) Acts as a enzyme b) Secreted from Juxtaglomerular apparatus c) Secreted in response to reduced efferent arteriolar pressure d) Reduced Na+ content in fluid of distal convoluted tubule causes secretion e) Plasma renin activity measured in hypertension Answer hint: Renin referred to as a hormone although it has no peripheral receptors and rather has an enzymatic activity with which it hydrolyzes angiotensinogen to angiotensin
