Understanding Respiration, Exercise Physiology, and Hydration
Respiration
Ventilation, Diffusion, and Transport
Ventilation refers to the airflow in and out of the lungs. Diffusion involves the exchange of oxygen (O2) and carbon dioxide (CO2) between the blood and lungs/tissue. Transport is the movement of O2 and CO2 between the lungs and tissues. Finally, internal respiration is the cellular exchange of O2 and CO2.
Oxygen Affinity Determinants
- Temperature: As temperature increases, oxygen affinity decreases.
- pH: A decrease in pH leads to a decrease in oxygen affinity.
Understanding Respiration, Exercise Physiology, and Hydration
Respiration
Ventilation
Ventilation is the process of air flowing in and out of the lungs.
Diffusion
Diffusion is the exchange of oxygen (O2) and carbon dioxide (CO2) between the blood and the lungs/tissues.
Transport
Transport refers to the movement of O2 and CO2 between the lungs and tissues.
Internal Respiration
Internal respiration is the cellular exchange of O2 and CO2.
Factors Affecting Oxygen Affinity
- Temperature: As temperature increases, oxygen affinity decreases.
- pH: A decrease in pH (more acidic)
Understanding the Respiratory System: From Ventilation to Disorders
Pulmonary Ventilation
Respiration
Respiration is the process of gas exchange within the body. It encompasses several key processes:
- Pulmonary Ventilation (Breathing): The flow of air into and out of the lungs.
- External Respiration: The exchange of oxygen and carbon dioxide between the alveoli (tiny air sacs in the lungs) and the circulatory system.
- Internal Respiration: The exchange of oxygen and carbon dioxide between the capillaries (tiny blood vessels) and the cells.
- Cellular Respiration: The breakdown
Respiration and Digestion: Processes and Functions
Respiration
Respiration is a process divided into two processes:
- External respiration is the gas exchange between the lungs and the atmosphere, where oxygen enters the lungs and carbon dioxide exits. It does not create ATP molecules.
- Internal respiration is the gas exchange between the bloodstream and the tissues, where oxygen enters the tissues to create ATP molecules and carbon dioxide exits.
Organs of the Respiratory Tract
The respiratory tract is divided into the upper respiratory tract (nasal cavity,

1. What is considered objective information.
Is the one that is measurable or verifiable in some way. Might be the patients pulse rate. A sign is objective information
2. What is a pertinent negative.
Signs or symptoms that might be expected, based on the chief complaint, but the ptient denies having.
3. How do you document a patient’s chief complaint.
Should be in the patient’s own words or in the words of a bystander, if the patient is unresponsive.
4.
