# Talk:Heart

The heart is a muscular organ in most animals. This organ pumps blood ttory system.[1] The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs.[2] In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest, called the mediastinum.[3]he heart is a muscular organ in most animals.

It would be very nice to have 3D model of the heart, so that people can explore it from thier prefered angle; I uploaded this one. But it was not accepted what would need to be changed/updated about the model before it would be acceptable for the article? then we can also update the model at List of organs of the human body

"The heart is a muscular organ found in most animals." 
As far as I know, arthropods don't have blood vessels and don't have a heart.

An underexplained edit from 2017 is the culprit there. I've reverted. Ugh, Remsense ‥ 论 12:42, 22 December 2024 (UTC)
Thanks! 2003:E7:EF33:6400:C76A:93E:D009:41EF (talk) 12:56, 22 December 2024 (UTC)
Thank you as well! Sometimes questions as important as that one just don't get asked by editors who don't notice, no matter how astute they are. Remsense ‥ 论 12:58, 22 December 2024 (UTC)

The heart produces a hormone, from the cardiac muscles, which is released when extracellular fluid volume is too high. This hormone functions to lower the blood extracellular fluid volume, and increase sodium excretion from the kidneys. Source? There is a page for it in Wikipedia, this very app. You can find a link to it in the aldosterone page (there is a section in the introduction which says that aldosterone's affects "are the exact opposite of the *whatever the heart hormone's name was* secreted by the heart".
