2.	Revise the vocabulary concerning the circulatory system.
The left ........................... is one of four chambers (two atria and two ventricles) in the human heart. It receives ........................... blood from the ...........................atrium via the mitral valve, and pumps it into the ...........................via the aortic valve.

The right ........................... is one of four chambers (two atria and two ventricles) in the human heart. It receives ........................... blood from the........................... ........................... via the tricuspid valve, and pumps it into the pulmonary artery via the pulmonary ............................
 
3.	Discuss in pairs.
a)	What are the factors which increase the risk for coronary heart disease?

b)	Which symptoms are associated with coronary heart disease?

b)	What do we call it if
a)	there is a type of chest pain that occurs when there is not enough blood flow to the heart muscle, often the result of narrowing of the coronary arteries
b)	it occurs predictably with a specific amount of exertion or activity

c)	What do we call it when
a)	one of the plaques, or one of the narrowings in the artery wall ruptures
b)	it is characterized by an accelerating  pattern of chest pain that lasts longer than in stable angina
c)	it occurs at rest or with less exertion than in stable angina, or is less responsive to medication.
 
d)	What do we call it if
