A kidney machine removes solutes from the blood by means of?

A kidney machine, or dialysis machine, removes solutes from the blood primarily through a process called diffusion. During dialysis, blood is passed through a semipermeable membrane that allows small solutes and waste products to pass through while retaining larger molecules and blood cells. Additionally, ultrafiltration is used to remove excess fluid by applying pressure, which helps in the removal of waste products and excess electrolytes from the blood. This process mimics the natural function of healthy kidneys in filtering blood.
