Lungs are more similar to an apple at 83%. And even seemingly dry human bones are 31% water. If we are essentially made of water, and surrounded by water, why do we still need to drink so much? 肺的含水量和苹果接近,有38% 。即使看起来很干燥的人的骨头也含有31%的水。如果人类主要由...
Small cell lung cancer (SCLC), sometimes referred to as "oat-cell carcinoma," occurs when the cells in your lungs start to grow unusually or uncontrollably. This unusual growth takes place inside your lungs or the lining of the airways. As more cancer cells grow, they can form into a tum...
How does COVID-19 take over a patient's system? RAZOR has been exploring a new theory about that and finds out what causes fluid build-up in patients' lungs. The premise is that an excess of bradykinin, an inflammatory molecule made up of a short chain of amino aci...

This is made of a tight mesh of cells which separate blood vessels from the brain, 这种隔膜由紧密的细胞网构成将血管与脑部分开 and block everything except for a specific set of particles, 并阻挡一切物质进出 including water molecules and some gases. ...
The body's unique physical structure gives us the ability to stand up straight against the pull of gravity. Our blood depends on us moving around to be able to circulate properly. Our nerve cells benefit from movement, ...
All this fits with the evidence that the predominant pattern of lung lesions in patients with COVID-19 patients is a diffuse alveolar damage, with the presence of platelet–fibrin thrombi in small arterial vessels, and the great majority of the inflammatory cells infiltrating the lungs are ...
How Our Lungs Work: Main Processes & Function from Chapter 21 / Lesson 2 32K Our lungs work by bringing in oxygen and expelling carbon dioxide so that our cells work properly. Explore the main processes and function of the lungs and learn about the lungs' role in ...

In the brain, increased neural activity is correlated with increases of cerebral blood flow and tissue oxygenation. However, how cerebral oxygen dynamics are controlled in the behaving animal remains unclear. We investigated to what extent cerebral oxyge
