Why is arterial bleeding viewed as so much more serious than venous or capillary breathing?

Arterial bleeding is considered more serious than venous or capillary bleeding because it involves the loss of oxygenated blood under high pressure, which can lead to rapid blood loss and shock. The bright red color of arterial blood indicates it is rich in oxygen, and when arteries are severed, the blood can spurt out forcefully, making it harder to control. In contrast, venous bleeding is typically darker and flows more steadily, while capillary bleeding usually involves minor injuries that are less likely to be life-threatening. Immediate medical intervention is critical for arterial bleeding to prevent serious complications or death.
