A new lung function has been discovered - they make blood

Researchers have discovered that the lungs play a far more complex role in mammalian bodies than we thought, with new evidence revealing that they don't just facilitate respiration - they also play a key role in blood production.In experiments involving mice, the team found that they produce more than 10 million platelets (tiny blood cells) per hour, equating to the majority of platelets in the animals' circulation. This goes against the decades-long assumption that bone marrow produces all of o
