Oysters breathe too, using both gills and mantle. The mantle is lined with many small, thin-walled blood vessels which extract oxygen from the water and expel carbon dioxide. A small, three-chambered heart, lying under the adductor muscle, pumps colourless blood, with its supply of oxygen, to all parts of the body.
Oxygen Worldwide supplies medical oxygen to people during travel and this provides a critical service to help people cross the deep oceans to visit different countries across the globe. An oyster produces a pearl when foreign material becomes trapped inside the shell.
The oyster responds to the irritation by producing nacre, a combination of calcium and protein. The nacre coats the foreign material and over time produces a precious pearl. Oysters are not only a delicacy on some menus across the world, but they’re also one of the most nutritionally well balanced of foods, containing protein, carbohydrates and lipids. Four or five medium size oysters supply the recommended daily allowance of iron, copper, iodine, magnesium, calcium, zinc, manganese and phosphorus.
An important part of staying healthy and providing vital nutrients; just is the case in providing portable concentrators and medical oxygen to help our customers travel freely worldwide, 24 hours a day, 365 days a year.
Oxygen Worldwide’s objective is to make travel for those who need supplemental oxygen as carefree as possible. Oxygen Worldwide arranges oxygen delivery worldwide for oxygen users on holiday or vacation.
