What purpose does blood serve?
Can someone please help me with this? What purpose does blood serve in the body?
Does it pass out nutrients from digested food to the whole body? If so, what is that called?
Or does it carry out oxygen to the parts of the body? If so, why is that crucial?
Also, if blood is 90% water, can water serve as some kind of substitute?
Thanks contained by advance!
Answers:
Blood has many different purposes.
Firstly blood carry oxygen from our lungs to our cells. This is necessary for respiration to take place. Respiration releases force from our food by reacting the glucose that was in our food (when the food be digested it was absorbed into or blood-stream and carried to the cells too. Second function: carrying glucose) the the oxygen.
glucose+oxygen -----> carbon dioxide+ river & energy transfer!
3rd function of blood is to carry the carbon dioxide from the cell to the lungs.
4th function is to carry white blood cells. white blood cells support fight against viruses and bacteria. (red blood cell carry the oxygen.)
5th function is to clot if you cut yourself. if the blood clots around the cut, the blood will be too thick to pass and little blood will be lost.
I dont give attention to water will be an ok alternative because it doesnt contain the red or white blood cells. without red blood cell you will die within 6 minutes as respiration wont be able to occour. This is what cyanide does in a round-about sort of instrument. The water will be way too thin to be an alternative to blood.
To recap:
functions of blood:
1) take oxygen
2) carry glucose
3)carry carbon dioxide
4) white blood cells
5)to clot when necessary
Oxygen is requirement in the body for respiration.
water is not a good substitute.
Blood have many functions, the main ones you have already spelled out. The blood is sometimes even call a tissue.
* It carries oxygen from the lungs to the cells that needs it for optimal metabolism (energy production). It also transports carbon dioxide for transport out of the body via lungs and kidneys.
* It transports nutrients to the cell and wast products to the liver and kidney.
* Blood also consist of different immune cells that keeps it clean of microbes and other alien material and transport white blood cells to places where they are needed.
* It also regulates warmth by rerouting the blood to peripheral organs like the skin to cool down.
* It carries signal molecules close to hormones to regulate different bodily functions like stress, hunger and fever.
Blood consists of plasma and cells.
Plasma is 92 % river and if you're dehydrated, the amount of plasma is reduced and can be substituted with water. In chock the dampen would be necessary to prevent the pressure from dropping hampering the circulation to important organs close to the brain. However the cells are important for oxygen transportation since hemoglobin is necessary to neatly bind oxygen and release it where it's required. Source(s): For further reading see:

1.) To deliver oxygen and other nutrients such as glucose to cells that are active around the body.
2.) To remove carbon dioxide and other spend foolishly products such as creatinine from active cells.
3.) To provide an immune respone to foreign objects or pathogens or indeed to stop bleeding. Source(s): http://wiki.answers.com/Q/What_is_the_purpose_of_having_blood_flowing_throughout_the_body
