McDonald's Airport Toys. While on the surface it sounds like a good idea: get an airplane as a toy and turn your Happy Meal box into the airport. However, when our clown-faced friend unveiled what has come to be known as the cheapest McDonald's toy of all time, kids were not excited.
Oxygen is carried in the blood in two forms: (1) dissolved in plasma and RBC water (about 2% of the total) and (2) reversibly bound to hemoglobin (about 98% of the total). At physiological PO2 (40 &#60; PO2 &#60; 100 mm Hg), only a small amount of oxygen is dissolved in plasma since oxygen has such a low solubility.
Blood contains a pigment called hemoglobin that carries oxygen to the tissues in the body. Oxygen is added to hemoglobin in the lungs and carried throughout the body through blood vessels called arteries and it is called oxygenated blood.lood in the arteries is oxygenated. Blood in the veins is de-oxygenated. With the exception of the pulmonary arteries which carry de-oxygenated blood, and the pulmonary veins â¦ that carry oxygenated blood.
