Some species have a few dozen predatory individuals living in small natural cavities. Some highly organised colonies may cover large territories and have millions of individuals. Ants are usually small, but can carry the weight of twenty ants. Worker ants carry food back to the colony so that other ants and the queen can eat.
What is the Juxtaglomerular Apparatus? The juxtaglomerular apparatus is a type of endocrine organ that is small in size, located within kidneys and helps in the regulating the function of nephrons. This is mainly involved in the secretion of renin and EPO in response to changes in the renal blood pressure or blood flow. Juxtaglomerular Apparatus are type of epitheloid cells that are located in the afferent arterioleâs media just at the place where it enters glomeruli. These cells of Juxtaglomerular Apparatus embed secretory granules which are limned on the membrane and constitute renin.
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.
