The chamber is the left atrium.
The lungs help exchange the deoxygenated blood which are full of wast materials into oxygenated and blood full of nutrients. These oxygenated blood are then transported through the pulmonary vein, the only vein in the body which transports oxygenated blood. These blood are then transported back into the heart, which is the left atrium specifically.
Those blood is then pushed down to the left ventricle, and then pumped to the whole body (except lungs), in order to keep the body functioning by providing oxygen and nutrients for cellular respiration.
Meanwhile, the deoxygenated blood are received by the right atrium, and is then transported back to the lungs for exchange again, through the right ventricle and pulmonary artery.
Life forms that depend on remineralize shells and skeletons will be harmed by ocean chemistry, as would species that are acid-sensitive and organisms higher in the food chain that eat these sensitive animals.
<h3>An organism is what, then?</h3>
An organism is a collection of molecules working together to form an more or less permanent together that demonstrates the characteristics of life. Definitions in dictionaries frequently use general terms like "any biological entity, such as a plant or animal reproduction."
<h3>What two kinds of organisms are there?</h3>
Prokaryotic and eukaryotic organisms are the two primary categories. These type the cells that form the organism are the basis for this differentiation. Prokaryotic cells have a very basic, rudimentary structure without a nucleus. Additionally, membrane-bound organelles are absent.
