Kidney tubules. Fluorescent light micrograph of a section through kidney tissue showing numerous tubules (black/green). The tubules are seen in cross-section. Their walls are black,with cell nuclei stained purple. The inner lining of the tubules is green. Tubules are part of the filtration system in a kidney. Blood passes through capillaries in the kidney,and fluid and molecules of waste products pass into the tubules. During the passage through the tubules,much of the water is reabsorbed,leaving a concentrated solution of waste products. This drains to the ureters,which pass it to the bladder as urine | |
