<span>Right atrium
The answer here requires you to know what the systemic circuit is. That's the circuit that takes oxygenated blood from the heart to the rest of the body and then returns the deoxygenated blood to the heart. With that in mind, let's look at the 4 chambers of the heart.
Left atrium gets oxygen rich blood from the lungs and pumps it into the left ventricle.
So we know this isn't the correct chamber and we can also ignore the left and right ventricles as well since they receive blood from their respective atriums.
That leaves only the right atrium and it's definition is
Right atrium gets oxygen poor blood from the body and pumps it into the right ventricle.
And that does sound like the correct chamber to me. So the answer is "right atrium"</span>
Phospholipids are typically made up of two fatty acids,a glycerol molecule and a phosphate group that is modified by an alcohol.The phosphate group is negatively charged, it is hydrophilic and it is describes as the polar HEAD of the phospholipid. The fatty acid chains have no charge [neutral], they are hydophobic and they are describe as the non-polar TAIL of the phospholipid.
There are some differences, though. Mammals have hair all over their bodies, while reptiles have scales. Mammals have live births and produce milk for their young, while reptiles lay eggs. Reptiles have only three-chambered hearts, mammals have four
