why do you think it would be very dangerous to lose a quart of blood in an accident?
Since the average adult has about 5 quarts of blood, the volume would be reduced by about 20%. Blood donors are limited to one pint (about 10%).
Since this is not my area of expertise, I searched Google under the key words "blood volume loss" to get this:

Losing a quart of blood, which is approximately 25% of the average adult's total blood volume, can be very dangerous for several reasons. First and foremost, blood carries oxygen and nutrients to all organs and tissues in the body. When a significant amount of blood is lost, the body's ability to provide enough oxygen and nutrients to its vital organs is compromised. This can lead to organ damage or failure if not addressed promptly.
Additionally, blood plays a crucial role in maintaining proper blood pressure. When blood volume drops due to loss, blood pressure decreases, which can lead to dizziness, lightheadedness, and potentially fainting. Low blood pressure also limits the body's ability to deliver oxygen to the brain, which can cause confusion, disorientation, and even loss of consciousness.
Moreover, blood loss can disrupt the body's ability to clot, increasing the risk of uncontrolled bleeding. When blood clotting is impaired, even minor injuries can result in excessive bleeding, making it harder for the body to stop the bleeding and potentially leading to a life-threatening situation.
In summary, losing a quart of blood in an accident can be dangerous due to the decreased oxygen delivery to vital organs, low blood pressure, and impaired clotting ability, which can all have severe consequences if not addressed promptly and appropriately.
