In most insects, this "blood" does not contain oxygen-carrying molecules such as hemoglobin because their bodies are small enough for their tracheal system to suffice for supplying oxygen. Jawed vertebrates have an adaptive immune system, based largely on white blood cells. White blood cells help...
That's because hemoglobin determines the blood's oxygen-carrying capacity, Okwuosa said. And donors could run a risk that not enough oxygen will be carried to their tissues and organs. Such donors withheart failurecould experience an episode or those withcoronary artery diseasecould have aheart a...

More specifically it relates to oxygen carrier compositions for the delivery of oxygen to tissues and organs (e.g., to the myocardium) under bloodless situations. It further relates to medical uses and methods of treatment comprising the administration thereof, for instance, as delivery vehicle for...
An oxygen-carrying blood substitute preparation stable upon storage is provided. The preparation comprises an oxygen-carrying substance capable of reversibly binding and releasing oxygen in vivo and an amount of a physiologically tolerable reducing agent effective for preventing at least partially irreversibl...

of unwarmed skin is near zero, the success of the transcutaneous oxygen electrode depends on producing enough local vasodilation to compensate for the arterial-capillary gradient and also for the further loss of oxygen due to skin metabolism and imperfect diffusion of oxygen through the skin layer....
infrared, through the skin and into the underlying blood vessels. Inside the blood vessels, the light interacts with the oxygenated and deoxygenated hemoglobin in the red blood cells. The amounts of reflected and backscattered light are used to calculate how much oxygen your blood is carrying. ...
However, determining the oxygen-carrying capacity of Hb is complicated by the fact that both carboxyhemoglobin (COHb) and methemoglobin (MetHb) are forms of circulating Hb that do not bind oxygen. Carboxyhemoglobin occurs when carbon monoxide (CO) binds to Hb. Smokers have increased carboxy...
Imagine your blood is like a team of tiny superheroes working hard inside your body. One of the main heroes in this team is called “red blood cells,” and they have a special job – carrying oxygen to every part of your body.
