To stay in circulation it has to squeeze through gaps in the spleen that are a quarter of a micrometre to just over one micrometre wide. It can do this because its membrane is held from the inside by a flexible mesh of a protein called spectrin, which lets the disc fold and spring back. Cells that have become too stiff or too round get caught in those gaps and are removed. In hereditary spherocytosis, faults in this mesh, or in the proteins that anchor it to the membrane, make the cells rounder and less flexible, so the spleen clears them early. That is why removing the spleen helps some patients.\u003c\/p\u003e\n\n\u003ch2 style=\"margin-top:2em;\"\u003eExplore Related Cellular Biology Jewelry\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/red-blood-cell-studs\"\u003ered blood cell studs | silver\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\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/red-blood-cell-earrings\"\u003ered blood cell earrings | silver\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/antibody-studs-gold-vermeil\"\u003eantibody studs | 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 are they, and how do they fasten?\u003c\/h3\u003e\n\u003cp\u003eEach stud measures 8 mm (about 0.3 inches) across, not counting the post. That is less than half the width of a US dime or a 1-cent euro coin, so they sit small and close to the earlobe. They fasten with gold vermeil posts and ear nuts at the back. 18K gold vermeil means 2.5 microns of 18K gold over solid sterling silver, nickel-free and hypoallergenic. To keep the gold bright, wipe them with a soft cloth and store them dry in their box.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-top:1.75em;\"\u003eIs there a silver pair, or a matching necklace?\u003c\/h3\u003e\n\u003cp\u003eYes. Red blood cell studs also come in sterling silver, at the same 8 mm. Choose the finish she already wears: the design is the same in both. For a set, the red blood cells necklace L comes in sterling silver and in gold vermeil, with a 26 mm pendant. The smaller S necklace, at 17 mm, comes in both finishes too.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-top:1.75em;\"\u003eIs delivery free, and what if they aren't right?\u003c\/h3\u003e\n\u003cp\u003eYes. DHL Express delivers free in 1-5 business days worldwide, and we pay the import duties and taxes, so nothing is due at the door. They arrive in a ready-to-gift jewelry box and festive envelope.

In April 1674 he looked at blood from his own hand and wrote to Henry Oldenburg of the Royal Society in London that it consists of small round globules in a crystal-clear, watery fluid. That June he reckoned the red globules to be 2,500 times smaller than a grain of sand, which, he added, “perhaps will to many seem incredible”. The Dutch naturalist Jan Swammerdam had seen red cells in frog blood years earlier, but his notes were only published after his death.\u003c\/p\u003e\n\u003c\/section\u003e\n","brand":"sciencejewelry1824","offers":[{"title":"Default Title","offer_id":56977396793730,"sku":"ER0060-GV","price":200.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1411\/4806\/files\/red-blood-cell-studs-gold-vermeil.png?v=1791899184","url":"https:\/\/sciencejewelry1824.shop\/products\/red-blood-cell-studs-gold-vermeil","provider":"sciencejewelry1824","version":"1.0","type":"link"}
