How does cohesion and adhesion help in blood circulation?

Cohesion and adhesion play crucial roles in blood circulation by facilitating the movement of blood through the vascular system. Cohesion, the attraction between similar molecules, helps maintain the integrity of the blood column, allowing it to flow smoothly through vessels. Adhesion, the attraction between different substances, enables blood to adhere to the walls of blood vessels, promoting efficient transfer of nutrients and gases. Together, these properties ensure effective circulation and oxygen delivery throughout the body.
