She could be missing the vein or be agains a valve in the vein
The person's white blood cells would attack it and kill it because it thinks it is a foreign disease or foreign object, and tries to save the body.
well it depends what was happening to cause the loss of blood if someone was slashed by a bear their heart rate would be very high if someone was just donating alot of blood it would be slow, in general losing blood = slow heart rate, basically like being sufficated because that's basically whats happening
I would assume the expression thin and thick blood would have to relate to how quickly it coagulates. It should make no difference on average although the tendency that the existing uric acid has to crystallize the cause of gout is reduced by putting more water into the system.
The valves have to open to let blood flow into a chamber, and close before the blood flows back. If the valves do not open and close precisely on schedule, or if they fail to open or close completely, the blood will not flow efficiently. This can cause fluctuations in blood pressure, lack of flow to organs, or damage to the muscles of the heart. For example, if the aortic valve between the heart and the aorta does not close after the left ventricle contracts, there will be back pressure into the ventricle, less blood pumped out of the heart, and lower pressure in the arteries.
Damage to heart valves would cause backflow of the blood meaning the heart would be unable to supply parts of the body with oxygen. In serious cases this could lead to stoke or heart attacks.
When the nurse needs blood.
Usually it would cause low blood pressure from dehydration and hypovolemia.
The most likely answer would be that the nurse hit a nerve that went down to your hand.

if the heart stops
Because you will have to know what chemicals such as pills or injections would cause harm to a patient
It could cause leukemia, the cancer of blood.

viens are closer to the skin, finding an artery would be more difficult. it will also cause a dipper wound and since the arteries are pressurized they may push the needle out and bleed harder. sometimes an inexpirienced nurse will hit and artery and the blood spray can be over two meters high.
No, because their blood also has the B Antigen which would cause a tranfusion reaction in the recipient.
Most blood tests are taken by a Nurse and analysed in a Lab, a Surgeon may refer to the results but would rarely take the test sample.
