Alveoli are the basic functional units of the human respiratory system, acting as tiny air sacs that exchange gases. Air inhaled through the mouth and nose flows into the lungs through the branched ...

Scientists have created a model alveolar system that mimics the breathing action of the human lung and allows visualization of flow patterns within the alveoli. The chip they designed includes tubes ...

Researchers have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study shows that the pupil is smallest during inhalation and largest during exhalation ...

Breathwork practices have emerged as powerful tools for managing stress and promoting mental well-being in our increasingly fast-paced world. While simple deep breathing serves as a helpful starting ...
