are medical doctors who specialize in disorders of the
cardiovascular system.
what are cardiologists?
they treat heart problems that usually do not require
surgery
perform surgeries on the heart and other organs of the
thoracic cavity.
what are cardiothoracic
surgeons?
perform CABG, heart valve replacement, correction of
congenital heart defects
what are cardiovascular are surgeons who specialize in surgery of the heart and
cardiac surgeons? the major blood vessels that surround the heart.
specialize in the treatment of peripheral arteries and
vascular surgeons
veins.
cardiovascular are practitioners who assist physicians by performing
technologists diagnostic and monitoring procedures using ultrasound.
cardiac sonographers or are technologists who use ultrasound to observe the
echocardiographers heart chambers, valves, and blood vessels.
or phlebotomy technicians assist physicians by drawing
phlebotomists
patient blood samples for laboratory testing.
are highly trained health care professionals who
perfusionists operate the heart-lung machine during cardiac and
other surgeries that require cardiopulmonary bypass.
Your heart is roughly the size of your fist, weighs
how much does your heart
approximately 8 to 10 ounces, and pumps around 2,000
weigh?
gallons of blood each day.
, Your heart is always working. When your heart fails to
what happens when your work, your blood stops circulating, your tissues stop
heart stops working? receiving oxygen and nutrients, your metabolic wastes
accumulate, and your cells die.
The heart is located in the
thoracic cavity between the
lungs, in an area called the
mediastinum.
where is the heart located?
The heart is shaped like a blunt
cone, pointing down and to the
left. It rests at an angle with the
majority of its mass to the left of
the sternum
1) Pump blood. As your heart contracts, it generates
pressure that moves your blood forward through your
blood vessels.
2) Route blood. Your heart essentially has two pumps:
one on the right side that sends blood through the
pulmonary circulation of your lungs and back to the
what are the 3 functions of
second pump on your left side, which sends blood
the heart?
through the systemic circulation of your body. Your
heart valves make this one-way flow of blood possible.
3) Regulate blood supply. The changing metabolic
needs of your tissues and organs - ex. when you
exercise, are met by changes in the rate and force of
your heart's contractions
, 3!!!
1) Endocardium: Connective
tissue lining the inside of your
heart and in direct contact with
blood.
2) Myocardium: Cardiac muscle
cells that contract to enable your
heart to pump blood.
how many layers does the 3) Epicardium: An outer single
heart wall contain? layer of cells overlying a thin
layer of connective tissue.
The pericardium is a double-
layered connective tissue sac
filled with fluid that surrounds
and protects your heart.
The visceral layer is the inner
layer touching the heart, which
folds over on itself, becoming the
outer parietal layer.
1) The actions of the four heart chambers are
coordinated.
2) When the atria contract (atrial systole), the ventricles
relax (ventricular diastole).
tell me about the heartbeat 3) When the atria relax (atrial diastole), the ventricles
contract (ventricular systole).
4) Then the atria and ventricles all relax briefly.
This series of events is a complete cardiac cycle, or
heartbeat!!!
