The  muscles of the heart have their own blood supply and when constricted chest pain can occur.

Unstable angina is more serious and more unpredictable and can continue despite resting.


When an artery wall weakens it can bulge, or become distended. This is particularly serious when it  affect the arteries supplying the brain and the heart as it can rupture causing internal bleeding

An aortic aneurysm affects the body’s main artery.

Although aneurysms can appear anywhere in the brain, they are most common in arteries at the base of the brain.


Cancer is when abnormal cells divide in an uncontrolled way.  Leukemia is cancer of the body's blood-forming tissues, including the bone marrow, white blood cells and the lymphatic system. White blood cells mutiply and crowd out the oxygen carrying red blood cells. Some forms of leukemia are more common in children. Early signs can be flu like symptom with fever, night sweats and fatigue, loss of appetite and weight loss.

Deep Vein Thrombosis (DVT)

A deep vein thrombosis is a blood clot that can travel around the body and cause serious problems in the heart (a heart attack) or the brain (a stroke). Causes of a DVT include damage to the inside of a blood vessel due to trauma or other conditions, changes in normal blood flow, or a rare state in which the blood is more likely than usual to clot (hypercoagulability). There is an association with long haul flights.

Symptoms of DVT in the leg are throbbing or cramping pain in 1 leg, usually in the calf or thigh; swelling in 1 leg; warm skin around the painful area; red or darkened skin around the painful area; swollen veins that are hard or sore to the touch.  These can also occur in your arm or stomach.

Treatment can include anticoagulant medicine such as warfarin or rivaroxaban.


A bruise is a common type of haematoma- a localised bleeding outside of blood vessels, due to either disease or trauma including injury or surgery

In most cases  with movement, the hematoma eventually dissolves; however, in some cases they may continue to grow such as due to blood seepage or show no change. Surgery may be required if the blood does not disappear.

"The anatomy and physiology courses are very easy to use, you don't have to be a computer wiz. The tutor giving the lectures is very good and it feels as if your are sitting in the classroom with her. I like the fact that you are able to pause the films to complete worksheets and that you can go back and watch the films over again. Overall, it's a very good course and well worth the money."
