2. Cardiovascular system also know as “Circulatory system”
or “Vascular system.The cardiovascular system is one of
the most important processes in the body,the
cardiovascular system is an essential component of
maintaining homeotasis,a state balance among system
of the body,by circulating blood when it comes to
understanding your heart health, it’s important to be
familiar with parts of the cardio vascular system and hoe
the system work.
Cardiovascular System

3.  The cardiovascular system is the transportsystem of the
body,responsible for circulating and transporting nutrients
throughout the body.In addition to providing oxygen and
nutrients,blood also helps cleanse the body by collecting waste
product like carbon dioxide.The continuous,controlled
circulation of the blood the cardiovascular system provides is
what maintains homeostasis.With oxygen provided and waste
removed,the body can perform its normal functions.
Cardiovascular Function

4. 1. Blood
Blood is the fluid that carries the oxygen and nutrients vital to
the function of the body, as well as the waste that needs to
be removed. Without blood, the human body could not
function. Blood flows between the heart and the rest of the
body, with red blood cells providing oxygen and white blood
cells fighting foreign invaders. In the cycle of blood flow, the
lungs provide the oxygen that the blood delivers to the rest
of the body.
Cardiovascular System's parts and
its functions.

6. 2. Blood Vessels
Another essential part of the cardiovascular system is the
blood vessels, which are tubes that transport blood
throughout the body. There are so many blood vessels in the
body that if you laid the average adult's out in a line, the line
would be close to 100,000 miles long.
Based on their function, blood vessels are classified as either
arteries, veins, or capillaries. Arteries carry blood from the
heart to the body, and veins carry blood from the body to the
heart. Capillaries are extremely narrow, microscopic blood
vessels that connect arteries and veins.

8. 3. Heart
The heart acts as the pump that makes the circulation of blood-
and the oxygen and nutrients blood carries - to all tissues of the
body possible. If the heart stops pumping for even a few minutes, it
cannot deliver blood to the rest of the body, putting the individual's
life in danger.
In terms of structure, the heart has two sides and is divided into
four chambers: the left atrium, the right atrium, the left ventricle,
and the right ventricle. The thin-walled atria receive blood from the
veins, and the thick-walled ventricles pump blood out of the heart.
On the left and right sides of the heart, the atrium and ventricle
work together to pump blood through and out of the heart.

10. 1. Lungs
-The lungs are a major organ that is part of the
respiratory system, taking in fresh air and
getting rid of old, stale air. This mechanism of
breathing also helps to allow you to talk. By
taking in fresh air, the lungs are able to help
oxygenate blood to be carried around your
body.

11. Pulmonary Circulation
-The pulmonary circulation is a division of
the circulatory system in all vertebrates.
The circuit begins with deoxygenated
blood returned from the body to the right
atrium of the heart where it is pumped out
from the right ventricle to the lungs.

12. Pulmonary Artery
-Your pulmonary arteries carry oxygen-
poor blood from your heart to your lungs.
This is a vital function. Your blood needs
to reach your lungs to gain oxygen and
get rid of waste products like carbon
dioxide.

13. Right Atrium
-Right atrium: one of the four chambers of
the heart. The right atrium receives blood
low in oxygen from the body and then
empties the blood into the right ventricle.

14. Left Atrium
-Left atrium: one of the four chambers of
the heart. The left atrium receives blood
full of oxygen from the lungs and then
empties the blood into the left ventricle.

15. Right Ventricle
-Right ventricle (VEN-trih-kul): one of the
four chambers of the heart. The right
ventricle pumps blood low in oxygen to
the lungs. In the lungs, the blood then
gets a "refill" of oxygen.

16. Left Ventricle
-The left ventricle connects nearly all organ
systems through its function to pump
oxygenated blood to the body. Left ventricular
failure would likely result in impairment to all
other organ systems. Organs may react to low
ventricular function by initiating mechanisms to
increase blood delivery.

17. Venae Cavae
-The vena cava has two parts: the superior
vena cava and the inferior vena cava. The
superior vena cava carries blood from the head,
neck, arms, and chest. The inferior vena cava
carries blood from the legs, feet, and organs in
the abdomen and pelvis. The vena cava is the
largest vein in the body.

18. Aorta
-The aorta is the main artery that carries blood
away from your heart to the rest of your body.
The blood leaves the heart through the aortic
valve. Then it travels through the aorta, making
a cane-shaped curve that allows other major
arteries to deliver oxygen-rich blood to the
brain, muscles and other cells.

19. Systemic Circulation
-The systemic circulation provides the functional
blood supply to all body tissue. It carries
oxygen and nutrients to the cells and picks up
carbon dioxide and waste products. Systemic
circulation carries oxygenated blood from the
left ventricle, through the arteries, to the
capillaries in the tissues of the body.

20. Capilliaries
-Capillaries are delicate blood vessels that
exist throughout your body. They
transport blood, nutrients and oxygen to
cells in your organs and body systems.
Capillaries are the smallest blood vessels
in your vascular system.

22. Tips on how to take care of your
Cardiovascular System:
Cardiovascular health is dependent upon all parts of the
cardiovascular system working properly. There are many
ways to improve your heart health and work to promote
strong, efficient blood flow throughout the body. Even simple
lifestyle changes can help prevent cardiological issues.
Getting regular exercise. including aerobic exercise and
resistance training, eating a heart- healthy diet, and
managing stress are just a few of the steps you can take to a
healthier heart.

23. Facts and
Trivia
About Circulatory System

24. 1.)A human heart is
roughly the size of a
large fist.

25. 2.)The heart weighs
between 9 and 12
ounces (250 and 350
grams).

26. 3.)The heart beats about
100,000 times per day
(about three billion beats in
a lifetime).

27. 4.)An adult heart beats
about 60 to 80 times per
minute.

28. 5.)Newborns hearts beat
faster than adult hearts,
about 70 -190 beats per
minute.

29. 6.)The heart pumps about
6 quarts (5.7 litres) of blood
throughout the body.

30. 7.)The heart is located in
the center of the chest,
usually pointing slightly left.

31. 8.)Your heart is located in
your chest and is well
protected by your rib cage.

32. 9.)Every day, the heart creates
enough energy to drive a truck 20
miles. In a lifetime, that is
equivalent to driving to the moon
and back.

33. 10.)Because the heart has its
own electrical impulse, it can
continue to beat even when
separated from the body, as
long as it has an adequate
supply of oxygen.

34. Diseases Cure
and Prevention
Circulatory System

35. -A heart attack, also called a myocardial
infarction, happens when a part of the
heart muscle doesn't get enough blood.
The more time that passes without
treatment to restore blood flow, the
greater the damage to the heart muscle.
1)Heart Attack

36. -Coronary artery disease (CAD) is the
main cause of heart attack. A less
common cause is a severe spasm, or
sudden contraction, of a coronary artery
that can stop blood flow to the heart
muscle.
Cause

37. • Aspirin. Aspirin reduces blood clotting
• Clot busters (thrombolytics or fibrinolytics). These drugs help
break up any blood clots that are blocking blood flow to the heart
• Other blood-thinning medications
• Nitroglycerin
• Morphine
• Beta blockers
• ACE inhibitors
• Statins
Cure

38. • Choose Healthy Foods and Drinks. Choose healthy
meals and snacks to help prevent heart disease and its
complications
• Keep a Healthy Weight. People with overweight or
obesity have a higher risk for heart disease
• Get Regular Physical Activity
• Don't Smoke
Prevention

40. A stroke, sometimes called a brain attack,
occurs when something blocks blood supply to
part of the brain or when a blood vessel in the
brain bursts. In either case, parts of the brain
become damaged or die. A stroke can cause
lasting brain damage, long-term disability, or
even death.
2)Stroke

41. There are two main causes of stroke: a blocked
artery (ischemic stroke) or leaking or bursting of
a blood vessel (hemorrhagic stroke). Some
people may have only a temporary disruption of
blood flow to the brain, known as a transient
ischemic attack (TIA), that doesn't cause lasting
symptoms.
Cause

42. Ischaemic strokes can often be treated
using injections of a medicine called
alteplase, which dissolves blood clots and
restores blood flow to the brain. This use
of "clot-busting" medicine is known as
thrombolysis.
Cure

43. • Choose healthy foods and drinks. Choosing healthy meal
and snack options can help you prevent stroke
• Keep a healthy weight
• Get regular physical activity
• Don't smoke
• Limit alcohol
• Check cholesterol
• Control blood pressure
• Control diabetes
Prevention

45. An arrhythmia, or irregular heartbeat, is a
problem with the rate or rhythm of your
heartbeat. Your heart may beat too quickly, too
slowly, or with an irregular rhythm. It is normal
for your heart rate to speed up during physical
activity and to slow down while resting or
sleeping.
Arrhythmia

46. Narrowed heart arteries, a heart attack,
abnormal heart valves, prior heart surgery,
heart failure, cardiomyopathy and other heart
damage are risk factors for almost any kind of
arrhythmia. High blood pressure. This condition
increases the risk of developing coronary artery
disease.
Cause

47. The treatments used for arrhythmias include:
medicine – to stop or prevent an arrhythmia or
control the rate of an arrhythmia. electrical
cardioversion – a treatment that uses
electricity to shock the heart back into a
normal rhythm while you are anaesthetised or
sedated.
Cure

48. • Eat heart-healthy foods
• Exercise regularly
• Quit smoking
• Maintain a healthy weight
• Keep blood pressure and cholesterol levels
under control
• Drink alcohol in moderation
• Maintain follow-up care
