The airways that bring air into the lungs (the trachea and bronchi) are made of smooth muscle and cartilage, allowing the airways to constrict and expand. The lungs and airways bring in fresh, oxygen-enriched air and get rid of waste carbon dioxide made by your cells. They also help in ...

Mitochondria play an essential role in maintaining cellular health. When damaged, they are removed through a recycling process called mitophagy, which is crucial for the function of long-lived cells, especially in the brain. Impaired mitophagy has been strongly associated with neurodegenerative disorders...
The vegetable waste was chopped into small pieces (approximately 1 cm particle size), and raw material was introduced to three digester cells during the preprocessing stage of composting (3 m long, 1 m wide, and 1 m high; non-covered cement containers). To maximize microbial activity, the ...
