Study Notes
Blood Vessels and Cuts
- When we get a cut, it causes holes in the walls of our blood vessels, which can lead to unhealthy blood loss.
Coagulation Process
- Coagulation is the process of liquid blood becoming a solid clot to stop bleeding.
- It involves the formation of clots that work like natural Band-Aids to stop bleeding from inside the blood vessels.
- Three substances found in blood work together to make clots: platelets, clotting factors, and blood cells.
Platelets
- Platelets are tiny sticky cells found in blood.
- They spring into action when a blood vessel is damaged, responding to chemical signals sent through the blood.
- Platelets rush to the site of the cut and bleeding, sticking together and to the sides of the cut to plug the hole and stop the bleeding.
- They form a plug, which is the first step of the coagulation process.
Clotting Factors
- Clotting factors are proteins that help the platelets stick together and build fibers around the platelet plug.
- They can be thought of as spiders building a sticky web, making the plug stronger and keeping it in place.
Blood Cells
- Red blood cells and white blood cells can get caught in the web of platelets and fibers, becoming part of the clot.
- These extra cells help strengthen the clot.
Clot Function and Dissolution
- A clot stops blood from leaking out of a broken blood vessel while a cut heals.
- After a cut heals, the body breaks down the clot.
