Question

the blood vessel present at the middle of the U shaped tubule​

Answer 1

Answer:

The renal arteries carry a large volume of blood from the heart to the kidneys. The kidneys filter waste and excess fluid from the blood. You have two renal arteries. The right renal artery supplies blood to the right kidney, while the left artery sends blood to the left kidney.In the renal system, peritubular capillaries are tiny blood vessels, supplied by the efferent arteriole, that travel alongside nephrons allowing reabsorption and secretion between blood and the inner lumen of the nephron.
...The innermost layer, the tunica intima (also called tunica interna), is simple squamous epithelium surrounded by a connective tissue basement membrane with elastic fibers. The middle layer, the tunica media, is primarily smooth muscle and is usually the thickest layer.
