👉 Nepheline is a type of cell in the kidney that secretes hormones and enzymes. These cells are responsible for regulating blood pressure, maintaining electrolyte balance, and regulating calcium levels in the bloodstream. They also help to filter waste products from the blood and transport nutrients to the kidneys. Nepheline cells can be found in all parts of the kidney, but they are most abundant in the glomerulus, which is a network of capillaries that collect urine from the nephron.
