Haemostasis

Haemostasis is a normal physiological process the body enacts to prevent bleeding. In this video Professor Jon Gibbins, an expert in haemostasis and thrombosis, discusses the initial stages of this reactive response.

Often triggered by an injury such as a cut, tiny cells in the blood called platelets become activated to help stop excessive bleeding. The second stage of haemostasis, coagulation, is discussed in the next video.

You can find additional images and information on haemostasis on page 6 of the Week 2 supplement. If you need to revise the types of blood cells, you may find it helpful to look back at Step 1.9.

What are the different steps in the multi-step process of haemostasis? Do you think that one of the steps of haemostasis is more important than the others?
