Respiration Flashcards
What is External Respiration?
External Respiration are the processes that occur within the lungs. It involved exchange of CO2 and O2.
What is Internal Respiration?
Internal Respiration are the processes that occur to Gas exchange at the tissue level. It is where O2/CO2 are Delivered/Removed.
What is Cellular Respiration?
Cellular Respiration refers to the processes in which cells use O2 to generate energy (in the Mitochondria).
Aerobic Energy Systems.
What is the Conductive Zone?
The Conductive Zone transports filtered air to the lungs.
What is the Respiratory Zone?
The Respiratory Zone is where Gas exchange occurs (Alveolar region).
What’s Inspiration?
Inspiration is the active process of contracting muscles in order to Inhale.
What’s Expiration?
Expiration is the process of Exhaling. It may be Passive (Quiet) or Active (Forceful breathing during exercise).
What is Ventilation dependant on?
Ventilation is dependant on stimulation from the CNS, which is why when you take a Depressant (like Alcohol), it suppresses the Ventilation of the Respiratory system, potentially leading to Respiratory arrest.
What happens in the Capillaries?
Gases Diffuse.
What is Diffusion?
Diffusion is the movement of gas, liquids, or solids from a high concentrated region to a low concentrated region.
Diffusion only happens if a difference of concentration exists.
Called ‘Concentration Gradient’.
What’s O2 transport?
It’s the process where O2 is absorbed in lungs and carried to peripheral tissues.
What’s CO2 transport?
It’s the process where CO2 in blood is moved to Alveolar sacs for Expiration.
What’s VO2 Diff?
VO2 Difference is the difference between the amount of O2 in the Artery and Vein. It reflects the amount of O2 that was delivered to the muscle(s).
What’s VO2 Max?
VO2 Max is the maximum amount of Oxygen the body can absorb and utilize during Physical Activity.
What are Respiratory Dynamics?
Refers to body responding to increase for Oxygen at working muscles. Correlates to series of responses that attempt to match Oxygen delivery with demand.
What’s the ‘Rapid On’ phase?
Rapid On is the first phase where VE (Pulmonary Ventilation) is increased at a rapid rate, almost immediately upon onset of activity.
What’s the Second phase?
Characterized by a slower exponential increase from ‘Rapid On’
What’s Phase 3?
Characterized by the levelling off (‘Flattening the Curve’) of the VE at a new steady state level.
What is the Lag phase?
Lag phase occurs when there is an Oxygen Deficit (O2 Deficit) where the body cannot match the demands instantly as activity increases.
Trained people reach the steady state faster than untrained people.
What is the Ventilatory Threshold?
The Ventilatory Threshold is is where Ventilation increases much more rapidly than workload. Normally occurs at 65-85% of VO2 max depending on the individual.
What’s Lactate Threshold?
It’s where the increase in demand causes the Aerobic system to need help and call for support from the Anaerobic Lactic system.
This means lactate concentration in the blood begins to increase.
What happens when lactate blood levels increase?
When they increase rapidly, it causes: Onset of Blood Lactate Accumulation (OBLA).
What’s COPD?
Chronic Obstructive Pulmonary Disease (COPD), is a general term that describes a family of diseases that lead to a dramatic reduction in airflow through the Respiratory System.
Treatment includes not only medication but also supplemental oxygen therapy for severe cases of COPD, as well as respiratory muscle training.
