An aneurysm is a weakened, expanded portion of an artery. Ruptured aneurysms can lead to rapid blood loss. Describe the significance of an aortic aneurysm versus a digital artery aneurysm.
Think about how much blood volume passes through the aorta coming from the heart compared to the blood volume that passes through an artery in your finger :). The aorta sees ALL the blood of the body, and so an aneurysm would lead to MASSIVE internal bleeding and possibly death. An aneurysm in your finger would be a minimal event, as it probably sees very little blood pass through it. You would most certainly survive the digital artery aneurysm.
