There's a lot to love: Riesling can taste like peach or apricot, with a bolt of lime-like tartness. It's also incredibly aromatic, all jasmine and honeysuckle.
Hemoglobin is responsible for transporting oxygen from lungs to other parts of the body, where the oxygen can be used by other cells. Oxy-hemoglobin (HbO2) is the bright red hemoglobin that is a combination of hemoglobin and oxygen from the lungs.A hemoglobin molecule can carry a maximum of four oxygen molecules.emoglobin is responsible for transporting oxygen from lungs to other parts of the body, where the oxygen can be used by other cells.

However, if alveolar Po2 is 60 mm Hg, then arterial blood will have a Po2 of 60 mm Hg, in which case the hypoxemia is severe enough to stimulate peripheral chemoreceptors in the carotid and aortic bodies. In turn, the chemoreceptors instruct the medullary inspiratory center to increase the breathing rate.
