JGA (juxtaglomerular apparatus) is a group of specialized cells found in the kidney that plays a crucial role in regulating blood pressure. The primary function of JGA is to monitor the blood pressure and sodium levels in the blood and adjust the release of renin, a hormone that helps regulate blood pressure. When blood pressure is low, JGA releases renin, which triggers a series of chemical reactions that result in the production of angiotensin II, a powerful vasoconstrictor that narrows the blood vessels and raises blood pressure. Therefore, JGA helps maintain blood pressure within a healthy range, which is essential for optimal organ function and overall health.

Option a is the correct answer.
