Term
|
Definition
| AKA breathing; the process of inhalation and exhalation of air between the atmosphere and the alveoli of the lungs |
|
|
Term
|
Definition
| the process of gas exchange in the body |
|
|
Term
|
Definition
| normal rate for a resting adult is 12-20 RPM, 15-40 in children under 8 |
|
|
Term
|
Definition
| AKA inspiration; the act of drawing air into the lungs |
|
|
Term
|
Definition
| occurs when the pressure within the alveoli falls below atmospheric pressure |
|
|
Term
|
Definition
| AKA expiration; the act of expelling air from the lungs into the atmosphere |
|
|
Term
|
Definition
| contraction of the diaphragm and external intercostals increases thoracic volume so the lungs can expand |
|
|
Term
|
Definition
| occurs when the pressure within the alveoli is greater than atmospheric pressure |
|
|
Term
|
Definition
| relaxation of the diaphragm and external intercostals results in an elastic recoil of the chest wall and lung decreases thoracic volume so air moves from the lungs to the atmosphere |
|
|
Term
|
Definition
| AKA pulmonary respiration; blood gains O2 and loses CO2 |
|
|
Term
|
Definition
| the exchange of gases between the alveoli of the lungs and the blood in the pulmonary capillaries across the respiratory membrane |
|
|
Term
|
Definition
| AKA tissue respiration; blood loses O2 and gains CO2 |
|
|
Term
|
Definition
| the exchange of gases between blood in systemic capillaries and the tissue cells |
|
|
Term
|
Definition
| the metabolic reaction within the cell when it consumes O2 and gives off CO2 during production of ATP |
|
|
Term
|
Definition
| part of the brain stem that contains a rhythmicity center where the basic rhythm of breathing is |
|
|
Term
|
Definition
| Impulses to this area can alter RPM (eg. change in blood acidity) |
|
|
Term
|
Definition
| can detect blood pH in the aortic and carotid bodies |
|
|
Term
|
Definition
| send impulses to the medulla oblongata to alter the rate of breathing based on the acidity of the blood |
|
|
Term
|
Definition
| AKA alkalosis; medulla oblongata decreases the rate of breathing |
|
|
Term
|
Definition
| AKA acidosis; medulla oblongata increases the rate of breathing |
|
|
Term
|
Definition
| can cause acidity of the blood to rise- increasing the rate of breathing and causing shallow, fast ventilations |
|
|
Term
|
Definition
| instrument that measures the air volume exchange and rate of ventilation; O2 saturation is normal when 94% or higher |
