2. Listen and answer the questions:
The contraction of the heart muscle is caused by ____________.
The abbreviation for electrocardiogram is ________ or _________.
What are the individual phases of electrocardiogram and what happens during them.
3. Complete the gaps with only ONE most suitable word:
Cardiovascular system
The _________ (1) important muscle in the body is the heart. Without the heart and its
cardiovascular (circulatory) system, human life _________ (2) not be possible. The heart is
roughly the _________ (3) of a fist. It contracts _________ (4) an average rate of 72 times per
minute or nearly 38,000,000 times _________ (5) year. These rhythmic contractions are
_________ (6) the pulse rate and can _________ (7) felt in the radial artery of the wrist.
The human heart consists of four _________ (8), two atria (or auricles) and two
_________ (9). Each is made _________ (10) of several layers of cardiac muscle arranged in
circles and spirals. During the contraction phase, called the systole, oxygenated blood
_________ (11) pumped out of the left part of the heart into the aorta and from there through
the arteries to all organs of the body. Carbon _________ (12), a waste product of this process,
is collected in the blood. The blood is passed back to the right atrium through the _________
(13), where the deoxygenated blood is led to the heart, and the vena cava during the ________
(14) (or relaxation) period of the heart. From there, it is pumped into the right part of the heart
and to the pulmonary artery to be sent to the lungs, where CO2 is removed and oxygen is
added.
The rest of the system consists of _________ (15) (small arteries), venules, and
capillaries, the smallest of blood _________ (16). In total, _________ (17) are more than
70,000 miles of them in the human body.
The blood is made up of two parts - plasma and _________ (18). The plasma is a
clear, yellowish liquid _________ (19) transports the 25 trillion erythrocytes and the many
fewer white cells (_________ (20)). The white cells are important _________ (21) fighting
disease. _________ (22) in the blood permit clotting to take place at the site of a wound, thus
preventing excessive bleeding.
