Final answer:
The efferent arteriole connects the glomerulus to the peritubular capillaries and vasa recta in the nephron.
Step-by-step explanation:
The efferent arteriole can be identified as the blood vessel that exits the glomerulus. It connects the glomerulus, which is a network of capillaries in the nephron, to the peritubular capillaries and vasa recta.
The efferent arteriole is the vessel that exits the glomerulus and forms the peritubular capillaries and vasa recta. It is significant in the regulation of glomerular filtration rate (GFR) by carrying filtered blood away from the glomerulus to the peritubular capillaries. The afferent arteriole supplies the glomerulus with blood. Following filtration in the glomerulus, the blood that didn't pass through, along with the filtered blood, continues through the efferent arteriole, which then follows the renal tubule, playing a vital role in nephron function by forming the peritubular capillary network that surrounds parts of the renal tubule and in juxtamedullary nephrons forms the vasa recta.
