Our kidneys are such extremely complex yet reliably designed organs that we can survive with a single kidney working at a fraction of its capacity. Each of these two dark red, bean-shaped organs is about the size of an adult fist and performs many absolutely critical functions within our bodies. The kidney's primary function is to filter impurities and toxins from our blood.
Each kidney has three layers, called the cortex, the medulla, and the pelvis. Blood flows into the cortex and medulla through the renal artery. The renal artery then branches into smaller vessels which connect to a blood filtration unit within the kidney called a nephron. Two normal kidneys have about two million nephrons (60 miles in combined length), which purify all of the body's blood approximately every 50 minutes. Over 400 gallons of blood are pumped through the kidneys each day. After being purified, about 99% of the blood's fluid is recycled back into the body for further use.
Many engineers over countless hours have worked to design artificial kidneys. Why would anyone accept that these comparatively huge and inefficient artificial kidneys have an intelligent designer, yet refuse to see God behind the infinitely more intricately designed kidneys within our bodies?
