## Definition

the process of a liquid turning into a solid or a thick, jelly-like mass. In your body, it is how blood stops flowing from a cut.

For teachers: the process by which a liquid becomes a semi-solid or gel-like substance. In a medical context, it refers specifically to the clotting of blood to prevent excessive loss.

## Examples

- The blood began to coagulation almost immediately after the cut.
- The chef added lemon juice to the milk to speed up the coagulation of the curds for making cheese.
- Understanding the complex cascade of proteins involved in blood coagulation is essential for developing anticoagulant medications that prevent dangerous clots without causing excessive bleeding.
