List of longest-running U.S. primetime television series. This is a list of the longest running U.S. primetime television series, ordered by the number of broadcast seasons offered by a U.S. broadcast network or cable network in prime time on the show's original run.
juxtaglomerular apparatus (JGA). Consist of the juxtaglomerular cells of an afferent or efferent arteriole and the. macula. densa. cells of the distal convoluted tubule. The JGA helps regulate. blood pressure and the rate of blood filtration by the kidneys.Renin is released to the blood by JGA cells due to decreased renal blood flow or perfusion.Renin converts a plasma protein (angiotensinogen) into angiotensin I Angiotensin-Converting Enzyme (ACE) in the lungs convertes Angiotensin I into Angiotensin II.ells of the distal convoluted tubule. The JGA helps regulate. blood pressure and the rate of blood filtration by the kidneys. Renin is released to the blood by JGA cells due to decreased renal blood flow or perfusion.
Juxtaglomeruar Apparatus (JGA) consists of: 1) Juxtaglomerular cells (modified smooth muscle cells) of afferent arteriole including renin containing (synthesizes and stores renin) and sympathetically innervated granulated cells which function as mechanoreceptors to sense blood pressure.he macula densa senses the load and causes constriction of nearby afferent arteriole, increasing the resistance. This will return osmolality and filtrate flow rate to normal. Decreased renal arterial pressure leads to a decreased delivery of fluid (decreased osmolality or decreased flow rate) to the macula densa.
