The District of Columbia Voting Rights Amendment (proposed 1978) would have granted the District of Columbia full representation in the United States Congress as if it were a state, repealed the 23rd Amendment, granted the District unconditional Electoral College voting rights, and allowed its participation in the process by which the Constitution is amended.
The afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems.They play an important role in the regulation of blood pressure as a part of the tubuloglomerular feedback mechanism. The afferent arterioles branch from the renal artery, which supplies blood to the kidneys.The afferent arterioles later diverge into the capillaries of the glomerulus.he afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems.
The kidneys help to regulate the blood pressure by increasing (when blood pressure falls) or decreasing (when blood pressure rises) the blood volume, and also by the renin-angiotensin system described above. The kidney-fluid system is the main method of the long-term control of blood pressure. In addition to the RAAS sytem, renal blood flow is regulated by: Pressure Diuresis: As arteriolar blood pressure increases, so flow through the kidneys also increases and this increases filtration rate and urinary output.
