Parts of Our System
Arteries- tubes that carry blood away from
the heart
Veins- tubes that return blood to the heart
Capillaries- connect arteries and veins. They
are tiny tubes that exchange food, oxygen
and wastes between blood and body
cells.
Pulmonary circulation- is the movement of
blood between the heart and lungs
Coronary circulation- is the movement of
blood from within the heart chambers to
the heart tissues themselves
Systemic circulation- is the movement of
blood between the heart and the rest of
the body
Parts of Our System Continued.
Atrium- either section of the upper area of
the heart which is divided into left and right
chambers.
Capillary- a microscope, linking blood
vessel diastole-the relaxation stage of the
heart muscle in it’s normal cyclical rhythm.
Septum- a wall separating two cavities
,especially the left and right sides of the
heart.
Systole- the normal, rhythmic contraction of
heart muscles.
Vena Cava- either of the large veins,
superior or inferior, by which blood is
returned to the right atrium of the heart.
Ventricle- either of the two lower, pumping
chambers of the heart
The Heart
On average, your heart beats 70 times a minute.
When the heart pumps, the right side and left side work together. The
middle is just a wall.
It has 4 chambers.
The upper chamber receives blood entering the heart and pumps it to the
ventricles.
The right side receives blood carrying carbon dioxide to the body and
delivers it to the right ventricle (either of the two lower pumping chambers of
the heart).
The left receives the oxygen-rich blood from the lungs and delivers it to the
left ventricles.
Heart Attack
A heart attack is a clogged artery or a blockage caused by a clot.
Treatment:
Don’t eat a lot of fatty foods.
Drink Orange Juice.
Exercise regularly.
(CPR) or (AED)
cardiac drugs
breathing tubes and/or surgery
thrombolysis is a procedure that involves an injection of a clot-dissolving agent such as
streptokinase, urokinase, or tissue plasminogen activator
Heart Attack
Symptoms:
Pressure in the chest area,
the left arm,
and/or pressure in the area around the heart.
Atherosclerosis
When the fatty material, like cholesterol, accumulates on the
artery wall forming a plaque that obstructs blood flow.
Treatmentmedicine,
surgery,
high-fiber,
diet low in fat,
and exercise
