Answer:
Blood flowing to your lungs is full of carbon dioxide, which gets exchanged in your lungs and the blood flowing out of your lungs is clean/purified with oxygen in it.
gravity for those above your heart and valves for those below
The patient could have had a seizure. That would explain their eyes rolling back and the breathing stopped. Tubereculosis could explain vomiting blood if the blood came from the lungs. Those are also symptoms of shock.
One-way valves prevent the back flow of bloodThere are tiny one way valves throughout a vein. These stop blood from flowing backwards. Interestingly, when these valves in veins in the legs malfunction, the result are varicose veins.
The blood of the slain is talking about the blood of the people who were killed but you also need to explain what it means so when you write down the answer make sure you explain more cause my teacher wants a more explained answer so i am sure your teacher wants the same answer more explained.

The Continental Divide marks the high ridge in North America that separates waters flowing into the Pacific Ocean from those flowing into the Atlantic Ocean.

Veins have valves to make sure that blood flows in only one direction.
Blood type O can recieve any type of blood transfusions. They can also recieve any type of plasma. O positive is a common blood type and those with it should take advantage of donating both blood and plasma.
Make sure you eat different types of berries and nuts. Those really help with type B blood, which loves those antioxidants. Also drink plenty of water.
Blood flows through the circulatory system based on the pressure and resistance of those vessels. The nervous system helps to measure this, and adjusts how the vessels are compressed by the surrounding muscles based on how needed oxygen is to those muscles.
No, those are two different blood types. You may only have one. Ab+, AB-, A+, A-, B+, A-, O+, O-: these are the possibilities.
Blood types are defined by cell surface markers called antigens. For example, if you have the "A" antigen then you have type A blood. The antigens act as a backstage pass in your body giving it permission to be there. If you introduce a blood type that has different antigens than those occurring naturally on your blood cells, then those different antigens will be perceived as "foreign" by your immune system. That means that your immune system will treat the different blood type like it would an infection. Antibodies will bind to the foreign antigens causing them to clump (agglutinate) which can clog or block smaller blood vessels. This is especially dangerous in the kidney and can lead to renal failure and possibly death.
