"Kidneys" • Simplification of how blood is filtered by the kidneys.
.
Blood flows into your kidney through the renal artery. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein.

We know it's hard to believe, but this man was buried 2,400 years ago. ☠️
He's called the Tollund Man, and is what's known as a 'bog body' as he was discovered in one of the peaty wetlands. Found in Denmark in 1950, he is so well preserved because of the highly acidic water, low temperature, and a lack of oxygen in bogs. When they pulled him out, authorities initially mistook him for a recent murder victim because of the level of preservation.
