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would have granted the District of Columbia full representation in the United States Congress as if it were a state, repealed the 23rd Amendment, granted the District unconditional Electoral College voting rights, and allowed its participation in the process by which the Constitution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.
Some afferent arterioles can form directly of the arcuate, or even directly of interlobars. There are not arteries penetrating in the renal medulla. The veins are originated in the cortex and follow parallel to the interlobular, arcuate, interlobar, and segmental arteries until forming the main renal vein.Figure 1.he main renal artery arises from the aorta and it is divided, usually, into the anterior and posterior branches and sometimes also into an inferior division. This artery is divided to form the segmental arteries, usually four or five, although there are many variants.
