When it wears out, macrophages in the spleen and liver take it in, break down its haemoglobin and pull out the iron. That iron goes back to the bone marrow to build new red cells. The marrow needs around 20 to 25 milligrams of iron a day, and most of it comes from this recycling. The gut absorbs only about 1 to 2 milligrams a day from food.\u003c\/p\u003e\n\n\u003ch2 style=\"margin-top:2em;\"\u003eExplore Related Cell Biology Jewelry\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/macrophage\"\u003emacrophage necklace | silver\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/eosinophil-gold-vermeil\"\u003eeosinophil necklace | gold vermeil\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/red-blood-cells-necklace-s-gold-vermeil\"\u003ered blood cells necklace S | gold vermeil\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/red-blood-cells-18k-gold-plated\"\u003ered blood cells necklace L | gold vermeil\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003csection class=\"product-faq\"\u003e\n\u003ch2 style=\"margin-top:2em;\"\u003eFAQ\u003c\/h2\u003e\n\n\u003ch3 style=\"margin-top:1.75em;\"\u003eHow big is the pendant, and what chain comes with it?\u003c\/h3\u003e\n\u003cp\u003eThe pendant is 27 mm (about 1.1 inches), a little larger than a 2-euro coin.

While his family was at the circus, he pushed a small thorn into a see-through starfish larva. By the next morning, mobile cells had gathered around the thorn and were trying to swallow it. He called them phagocytes, from the Greek for devouring cells, and argued that they defend the body against intruders. He later gave the larger ones their own name, macrophages, the big eaters. In 1908 he shared the Nobel Prize in Physiology or Medicine with Paul Ehrlich.\u003c\/p\u003e\n\u003c\/section\u003e\n","brand":"sciencejewelry1824","offers":[{"title":"Default Title","offer_id":57028515758466,"sku":"NK0418-GV","price":345.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1411\/4806\/files\/macrophage-gold-vermeil.png?v=1794389255","url":"https:\/\/sciencejewelry1824.shop\/products\/macrophage-gold-vermeil","provider":"sciencejewelry1824","version":"1.0","type":"link"}
