O2 Transport
RESP
| Question | Answer |
|---|---|
| oxygen enters the plasma and maintains molecular struture and moves freely throughout the plasma | Dissolve |
| Hemoglobin is bound with O2 | Oxyhemoglobin |
| Hemoglobin id NOT bound with O2 | Deoxyhemoglobin |
| Different amino acid, RBCs are sickle-shaped | Sickle cell hemoglobin |
| Has a greater attraction to O2 | Fetal Hb |
| Means attraction to like molecules | Affinity |
| Pco2 level increases, oxyhemoglobin saturation decreases shifting curv to the right, Pco2 level decreases shifting curve to the left | Bohr Effect |
| Effects of Pco2 and pH on the oxyhemoglobin curve | Bohr Effect |
| Carbon monoxide is bound to hemoglobin | Carboxyhemoglobin |
| cardiac output that moves from right side of heart to the left side without being exposed to alveolar oxygen | Pulmonary Shunting |
| Has two major categories: anatomic shunts and capillary shunts | Absolute Shunt |
| Also called true shunts | Anatomic and Capillary shunts |
| Blood flows left to right side of heart without coming in contact with alveolus for gas exchange | Anatomic shunt |
| A healthy lung normal anatomic shunting of cardiac output | 3% |
| A shunt that can be treated with oxygen, is caused by aveolar collapse or atelectasis | Capillary shunts |
| Pulmonary capillary perfusion is excess of alveolar ventilation, CAN NOT be treated with oxygen | Relative shunt |
