I heard under the microscope they look the same. Also heard that during the blood shortage following 9-11. There was talk of using clean sea water mixed with blood to stretch the supply.

No! Blood is complex and full of cells. Purified sea water has, I believe, the same pH as human blood.

What you are referring to is the saline content of blood and salt water. Our blood has a salinity comparable to sea water. That is why saline solutions are used and called isotonic, because they are the same as our blood salinity. Hospitals regularly use saline solutions to keep vessel volume and pressure up during medical procedures. That is not to say that salt water can replace blood. The salt water has none of the cellular contents necessary to carry nutrients to the bodies cells. If there has been a severe loss of blood, saline solutions can be administered to keep vessel pressure up and the patient alive hopefully long enough to get real blood into the system.

Composition of Blood
The human blood is composed mostly of a fluid part called plasma in which red corpuscles, white corpuscles and platelets are suspended. Blood consists of 78 per cent of such fluid and 22 per cent of solids. The details of the constituents of blood are as follows:
Human Blood Water fluid 78 %
Solids 22 %
The break-up of the solids is as under: -
Proteins 18.5 per cent
Salts (Inorganic) 1.5 per cent
Lipids (Fats) 1.4 per cent
Glucose 0.1 percent
Waste products 0.5 per cent
But water isn't like blood. they could say that plasma like water but this is not true.

Blood is composed mainly of water, so is sea water, both contain salt, thats about the end of it. I once lost a lot of blood, and was told I had to have a blood transfusion. It was when blood was suspect (aids/HIV). so I refused it. They gave me a saline drip instead, which I suppose is about the same as sea water.

1. Blood has red blood cells, and seawater doesn't.
2. Blood has dissolved protein and hormone components, and seawater doesn't.
3. Blood has dissolved sugar components, and seawater doesn't.
4. Seawater is much saltier than blood.

actually, blood has the same constituents as Hershey's chocolate milk.
didnt you notice after 9/11 how hard it was to find chocolate milk?

when a shark bites a person's leg and they are bleeding in the ocean, they shouldn't have to worry about loosing blood then (other than it will attract more sharks).

only if the sea water had red and white blood cells of course not they are not even similar yes blood containes salts, water plasma ,RBC&WBC ,SEA WATER ARE MINERALS ,WATER AND SALTS, I DONOT THINK THEY ARE SIMILAR.
