Final answer:
The presence of pools of blood around internal organs is typically due to damage to blood vessels, resulting in leakage. The body's response to such bleeding involves blood platelets and certain proteins. Additionally, due to gravity, some blood can pool within blood vessels and lead to conditions like edema.
Step-by-step explanation:
The pools of blood surrounding the internal organs could be caused by a variety of reasons, most commonly due to a severance or damage to the blood vessels. This can cause blood components such as erythrocytes, white blood cells etc., to leak out. Hypovolemia or abnormally low levels of fluid and blood within the body can also cause this. In cases of bleeding, blood platelets and certain proteins dissolved in the plasma come into action to block the ruptured areas of the blood vessels thereby protecting the body from further blood loss. It's also important to note that some blood inevitably pools within blood vessels, due to gravity's pull, which can lead to conditions such as edema.
