Fig. 3: The BTC-HTBP system is altered under microgravity exposure, leading to diminished CO 2 gas exchange and respiratory efficiency. It is well-known that elevated CO 2 levels—whether in space or ...

With recent studies having established the presence of nano and microplastic particles in the respiratory systems of both human and bird populations, a new study has modeled what happens when people ...

A research team has successfully utilized human respiratory organoids (mini-organs) to propagate human rhinovirus C (HRV-C), which had previously been refractory to conventional virus cultivation.

Air sacs in the lungs called alveoli are crucial for gas exchange and provide an important barrier against inhaled viruses and bacteria that cause respiratory diseases like flu and tuberculosis (TB).
