The blood distributes nutrients and water. It distributes oxygen throughout the body and brings carbon dioxide back to the lungs to be exhaled. It also contains white blood cells and antibodies that aid the immune system.

What process moves nutrients from the mother to developing foetus?
In mammals this is done by the placenta, through which the foetal blood flows and exchanges nutrients/gasses with the mothers blood supply.
How is a full body blood transfusion done and how many units of blood are needed?
poopyjehf oe huhuh jheb bjiahb d jibwqjiebib uiebeqwijb ihjbqejib jiqebj The patient's blood is slowly withdrawn (usually about 5 to 20 mL at a time, depending on the patient's size and the severity of illness). An equal amount of fresh, prewarmed blood or plasma flows into the patient's body. This cycle is repeated until the correct volume of blood has been replaced. The volume is dependent on the size of the patient, therefore the units of blood required are variable.
Why does the brain need a constant blood supply?
The brain uses about half of the oxygen taken in. Actually the real answer is because the brain is extremely sensitive to changes in its circulatory supply. An interruption of circulation for several seconds will produce unconsciousness and after 4 minutes there may be some permanent brain damage.
What are iron tests?
a group of blood tests that are done to evaluate the iron level in blood serum, the body's capacity to absorb iron, and the amount of iron actually stored in the body.
What happens to the blood in the body?
Well dead blood isn't dead because it was never alive. It's apart of your body so when you die the blood flow stops. Usually they take your blood out or something else would be done depending on what the situation is... And I never give up hope on vampires! =3
How does the DNA in a transplanted organ get matched with the recipient's body?
Blood tests are done to determine whether there is a match.
Which organ transports oxygen to other body parts?
It is done by veins and arteries (known as blood capilleries) vien take impure blood from different body parts to heart which then carry to lungs for purification and from lungs this pure blood carry again to hear which is pumped by arteries to the different body parts. So blood capelleries, and heart help in transporting the blood.
Why is blood type very important?
blood typing is very much important while transfusing it. we cann't donate blood if the blood group of the donar do not match with the blood group of the recepient.If it is done so, there will be clotting of blood in the body of the recepient.
Why is the blood pressure lower in lung capillaries than body capillaries?
Because if blood pressure in lung capillaries was as high as it is in body capillaries, the hydrostatic pressure caused by this blood pressure would force blood plasma out of the capillaries into intracellular spaces (as is done in body capillaries) or into the alveoli. This would reduce the efficiency of gas exchange.
Where does the blood go after the exchange of carbon dioxide and oxygen?
Blood flows from the venous system to the right atrium of the heart to the right ventricle of the heart through the pulmonary arteries, to the lungs (where the CO2/O2 exchange is done) through the pulmonary veins, and back to the left atrium of the heart, to the left ventricle of the heart, and out through the aorta and to the rest of the body. It then returns through the veins and repeats the process.
Why is an endarterectomy done?
Removing the fatty deposits restores normal blood flow to the part of the body supplied by the artery
