There is no portal artery. A portal vein connects one capillary bed to a second capillary bed. (in series)
The terminal arteriole feeding the capillary bed leads into a metarteriole, which is continous with the thoroughfare channel. The thoroughfare channel, in turn, joins the postcapillary venue that drains the capillary bed.
Glomerulus in the bow man's capsule
Capillary refill refers to how quickly the color returns to the external capillary bed following pressure that has been applied to an area. A brisk capillary refill means that the color returned to the capillary bed rather quickly.
what funtion does the capillary loop have in the hair follicle

The first capillary bed in the series is the glomerular capillary, where filtration occurs. The efferent arteriole on the distal end of the glomerular capillary. Objects it to the next capillary bed in the series: the peritubular capillary. This is where secretion and reabsorbtion take place. This type of system is an example of an arterial portal system.
Pressure at capillary bed varies from 32mmHg at the arteriolar end to about 10mmHg at venous end, with an average of 17mmHg
capillary bed of the right kidney---venules---veins---right atrium---right ventircle---pulmonary arteries---capillary of the lungs---pulmonary veins---left atrium---left ventricle---aorta---arteries---arterioles---capillary bed of the left kidney (ALMOST positive about the answer, I just had a test on it. Hope it helps!)
