Final answer:
Penetrating trauma involves injury, platelet plug formation, and defense reactions.
Step-by-step explanation:
Penetrating trauma refers to an injury where an object, such as a bullet or a knife, enters the body and causes damage to the underlying tissues. The components of penetrating trauma include:
- Injury: A blood vessel is severed, leading to bleeding.
- Platelet plug formation: Platelets become activated and stick together at the wound site, forming a plug to stop bleeding.
- Defense reactions: The body activates defense mechanisms to protect the damaged tissue and prevent infection.
These components work together to respond to the injury and initiate the healing process.
