Does the heart oxygenate our blood also?

I know we have veins that carry the blood to the heart and veins that carry the blood throughout the body, oxygenated. Therefore the heart must also oxygenate the blood? I'd like as much detail as poosible, starting from the start eg. oxygen enters the lungs and ....

Oxygen enters the body through the mouth, down the trachea and into the lungs. There it is absorbed by the blood vessels that enter the lungs (really tiny blood vessels that are only one cell thick). This blood is pumped back to the heart, where it is then pumped throughout our body through the network of arteries. The blood oxygenates the tissues in our body and is then transported back to the heart through the body's network of veins. This old, deoxygenated blood enters the heart and is pumped back to the lungs to get reoxygenated and repeat the cycle. The heart does not actually oxygenate blood (this is done only in the lungs) but it circulates the blood throughout the body. One side of the heart recieves old and deoxygenated blood and pumps it to the lungs to be oxygenated, and the other side of the heart recieves the freshly oxygenated blood from the lungs and pumps it througout the body.
Hope this helps!

Oxygenation occurs in the lungs. The heart just moves the blood around to the body.

Oxygen goes into our lungs and from there goes into the aveoli sacs and there blood picks up o2 and carries it throughout the body. That is the gist of it.

nicely, in case you do have the means to drown interior the 1st place, the resultant pneumonia could be the least of your concerns, might it no longer? shall we anticipate which you in basic terms have been given distinctive salt water on your lungs, yet controlled to survive. Nature has a phenomona called osmosis, it incredibly is incredibly clever in plenty a situations, yet contained whilst it comes to drowning in salt water its undesirable. to describe: Osmosis is the the rigidity of attempting to make to seperate booths the comparable. in case you have a membrane it incredibly is semi-permeable to particular solutes and water, only like the tissue lining on your lungs, water and salt will circulate the two into your lungs or out of them finding on what the concentrations are on the two facet. in case you drink salt water, the salt concentration interior your lungs (the salt water) is greater than interior the tissue itself. hence, water wil rush out of your tissue into your lungs, until eventually the concentration of salt is the comparable on the two facet of the membrane (for this reason, the liner of the lungs). Its no longer an infection, in spite of the incontrovertible fact that it relatively is what you may call chemical pneumonia, and it relatively is amazingly risky. So, to sum up, its a query of concentrations. in case you have been to get an incredibly diluted salt water answer on your lungs, it does not be as undesirable.

YES FOR THE FIRST QUESTION.
NO. THE HEART ONLY PUMPS BLOOD, OXYGEN GETS ABSORVED THROUGH THE ALVEOLI INTO THE BLOOD STREAM
