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 ...

An artificial lung system sustained a patient for 48 hours without lungs, enabling a life-saving double transplant and ...

What happens in our respiratory tract once we’re exposed to COVID-19? A three-dimensional airway model, made from patient-derived stem cells, could provide answers about the initial stages of ...

In this video, I use a fun and easy model to break down how your lungs really work. With just a straw, a cup, and some balloons, I help you visualize the respiratory system and explain why breathing ...
