Respiration is a series of reactions, but this summarises the overall process. Human muscle can respire anaerobically for short periods of time – even though the process is relatively inefficient, ...

Soil respiration is the result of heterotrophic respiration (Rh) and autotrophic respiration (Ra), accounting for about 50%–75% of the total ecosystem respiration on land, which is crucial for the ...

A new study published in Science Advances reveals that cyanobacteria may survive prolonged heat stress not by protecting ...

Cheyne-Stokes respiration, or periodic respiration, involves an atypical pattern of breathing. It consists of cycles of deep breathing followed by shallow breathing. Cheyne-Stokes breathing can be a ...

Painful respiration can involve lung pain that occurs when a person breathes in or out. Infections, musculoskeletal injuries, and heart problems can cause this pain. The lungs do not have pain ...

A new study challenges a long-standing assumption about how cyanobacteria survive environmental stress. The study, led by ...

Here we describe the case of a patient (Patient 1) who was hospitalized for non–ST-segment elevation myocardial infarction. After the patient underwent complete revascularization for three-vessel ...

As we get older, we humans experience some decreases in function in multiple domains. But how much of these decreases are due to real decline and how much to disuse? And what can be done about it?

Breathing refers to the physical act of inhaling and exhaling air through the lungs. It involves the movement of air in and out of the body, which is facilitated by the diaphragm and other muscles of ...

Respiration close respirationA chemical reaction that occurs in the mitochondria of cells in which glucose and oxygen react to produce carbon dioxide and water, releasing energy. is a chemical ...
