Uncover the distinct roles of interstitial and extracellular fluids in the body, their composition, and impact on health and disease.
Explore cardiopulmonary anatomy and physiology, learning about the functions of the cardiovascular and respiratory systems.
Explore the intricacies of lung anatomy, dispelling the myth of ‘hollow’ lungs while highlighting their essential role in respiration.
Explore effective methods to increase blood oxygen levels for optimal health, from lifestyle changes to specific therapeutic interventions.
Explore the anatomy and physiology of the vallecula, including its structure, location, function, and clinical relevance.
Discover the depolarization and repolarization processes of the heart, which creates the electrical activity of the cardiovascular system.
Discover the most unusual breathing reflexes and their significance: coughs, sneezes, hiccups, yawns, sighing, and the mammalian dive reflex.
Air is a homogeneous mixture of several gases; therefore, it is not a mixture. These gases are distinct and can be physically separated.
Dead space ventilation is the volume of ventilated air that does not participate in gas exchange. It’s often known as “wasted ventilation.”
This study guide provides an overview of the cardiovascular system and has helpful practice questions on this topic.
This study guide has practice questions on the topic of cardiopulmonary anatomy and physiology (Cardio A&P) for respiratory therapy students.
Alveoli are tiny air sacs arranged in clusters in the lungs where the gas exchange of oxygen and carbon dioxide molecules takes place.
This review guide (with practice questions) covers the respiratory system, lungs, and other structures involved in the breathing process.
The factors responsible for holding the lungs to the thorax wall are surface tension from pleural fluid and negative pressure.
Under what internal conditions does air tend to flow into the lungs? The simple answer is that it occurs due to a pressure gradient.
