The global Human Cell Atlas consortium is developing and using experimental approaches to create comprehensive reference maps of all human cells as a basis for both understanding human health and ...
Human Cell Atlas; Content; Description: The Human Cell Atlas is a global consortium that is creating detailed maps of the cells in the human body to transform understanding of health and disease. Organisms: Human: Contact; Primary citation: Regev, Aviv; et al. (Human Cell Atlas Organizing Committee) (2018). "The Human Cell Atlas White Paper".
The end-exhalatory lung volume is now well below the resting mid-position and contains far less air than the resting "functional residual capacity". However, in a normal mammal, the lungs cannot be emptied completely. In an adult human, there is always still at least 1 liter of residual air left in the lungs after maximum exhalation. [6]
The received wisdom said we were built from around 200 types of cell – such as heart muscle or nerve cells. Instead the Human Cell Atlas project has revealed there are thousands of cell types ...
The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...
The work is part of the ongoing Human Cell Atlas project that was begun in 2016 and involves researchers around the world. The human body comprises roughly 37 trillion cells, with each cell type ...
When a human being inhales, air travels down the trachea, through the bronchial tubes, and into the lungs. The entire tract is protected by the rib cage, spine, and sternum. In the lungs, oxygen from the inhaled air is transferred into the blood and circulated throughout the body.
Part of the cross section is magnified to show diffusion of oxygen gas and carbon dioxide through type I cells and capillary cells. Gas exchange in the alveolus. Type I cells are the larger of the two cell types; they are thin, flat epithelial lining cells (membranous pneumocytes), that form the structure of the alveoli. [3]
