Outcome 2 Understand the anatomy and physiology in relation to obtaining and testing capillary blood samples
The learner can:
1. Describe the structure and purpose of capillary blood vessels
A capillary is an extremely small blood vessel, which is located in the tissues of the body. Their purpose is to transport blood to the veins and arteries. The walls of the capillaries form the semipermeable layer through which fluids are exchanged between the blood and tissue fluids surrounding body cells. The walls of the capillaries are so thin that they are only made up of one or two cells. This means that they are so narrow that blood cells can only travel through them in single file.
2. Explain blood clotting processes and the factors that influence blood clotting.
Blood clotting is known as Coagulation. It is a series of physical reactions that transform liquid blood into a gel that forms a secure patch over the damaged blood vessel.
Coagulation has three main stages: Formation of factor x and prothrombinase, Prothrombin is converted to thrombin and finally Fibrinogen is converted to fibrin.
The clot is formed by these stages. A process called Clot Retraction then strengthens it. This is here platelet in the clot contract pulling on the fibrin strands that they are attached to.

Outcome 3 Be able to prepare to obtain capillary blood samples
The learner can:
1. Confirm the individual’s identity and obtain valid consent
Before taking blood introduce yourself to the patients. Explained the rationale for the procedure, the benefits, the potential risks and gains informed consent, discuss any medical history, medications, contradictions.
