| Term | Definition |
|---|---|
| Partial Pressure | Pressure exerted by an one gas in a mixture of gases or in a liquid. |
| Pulmonary gas exchange | oxygen diffuses in the pulmonary capillaries and carbon dioxide is exchanged in its place to be exhaled |
| Hemoglobin (Hgb) | iron-rich protein in red blood cells that carries oxygen from the lungs to the body and returns carbon dioxide for removal |
| Carbon dioxide-hemoglobin reaction | Carbon dioxide can bind to an amine group in an amino acid with a hemoglobin molecule to form carbaminohemoglobin and a hydrogen ion. |
| Bicarbonate | Crucial ion that acts a natural pH buffer in the body, vital for transporting carbon dioxide and maintaining acid-base balance |
| Systemic gas exchange | Process where oxygen-rich blood from the lungs releases oxygen to the body's tissues and picks up carbon dioxide, a waste product, to be transported back to the lungs |
| Bohr effect | Right shift of the oxygen-hemoglobin dissociation curve resulting from increased pco2 |
| Haldane effect | Increased total CO2 loading caused by a decrease in po2 |
| Antibodies | Y-Shaped proteins produced by plasma cells that identify and neutralize foreign invaders alike bacteria and viruses by binding specifically to their antigens |
| Effector Cells | Activated immune cells that carry out specific functions to eliminate pathogens or infected cells during an immune response |
| Naiive | B or T Cell that is inactive, meaning that it has not yet been exposed to a specific antigen |
| Antigens | Macromolecules that induce the immune system to make certain responses |
