Top 6 Unusual Breathing Reflexes of the Human Body (2023)
Discover the most unusual breathing reflexes and their significance: coughs, sneezes, hiccups, yawns, sighing, and the mammalian dive reflex.
Is Air a Compound or a Mixture? (Explained)
Air is a homogeneous mixture of several gases; therefore, it is not a mixture. These gases are distinct and can be physically separated.
What is Dead Space Ventilation? (Explained)
Dead space ventilation is the volume of ventilated air that does not participate in gas exchange. It’s often known as “wasted ventilation.”

Which of the Following is Not Transferred by Alveoli?
Alveoli are tiny air sacs arranged in clusters in the lungs where the gas exchange of oxygen and carbon dioxide molecules takes place.
Respiratory System Review with Practice Questions (2023)
This review guide (with practice questions) covers the respiratory system, lungs, and other structures involved in the breathing process.
What is Responsible for Holding the Lungs to the Thorax Wall?
The factors responsible for holding the lungs to the thorax wall are surface tension from pleural fluid and negative pressure.
What Internal Conditions Cause Air to Flow Into the Lungs?
Under what internal conditions does air tend to flow into the lungs? The simple answer is that it occurs due to a pressure gradient.
Ventilation-Perfusion Ratio: What is a V/Q Mismatch?
What is the Ventilation-Perfusion Ratio? What is a V/Q mismatch? This guide breaks it down and has practice questions on this topic.
Pulmonary Diffusion: Overview and Practice Questions
The process of pulmonary diffusion is a vital part of respiration and refers to the movement of gases between the alveoli and blood.
