The vein and or arteries have a very think layer of skin and prevent the "substances" from leaving.
Renal arteries are found in the renal helium.
Your renal arteries supply the kidneys with blood while the renal veins take it away back to the heart.
SecretionSecretion is the process by which substances move into the distal and collecting tubules from blood in the capillaries around these tubules.
Tubular secretion
YES
ureterurethra
Renal epithelial cells are the cells lining the renal tubules.
The renal papilla is located in the kidneys. The function of the renal papilla is to store urine before it is excreted from the bladder. It contains part of the secreting tubules and the collecting tubules.
Deoxygenated blood leaves the kidneys through the renal veins.
collecting ducts and uriniferous tubules
The parts of the nephron are the renal artery, renal vein, afferent arteriole, glomerulus, bowman's capsule, proximal tubules, distal tubules, loop of henle, renal pelvis, cortex, medulla, peritubular capillaries, and ureter.
The main capillaries of the renal cortex which arise from the efferent arteriole after it leaves the renal corpuscle and wrap around the renal tubules, especially the proximal and distal tubules, to supply nutrients and oxygen to the tubules, to carry away wastes from the tubular cells.
The renal pelvis or pyelum.
