2. The right side of the heart collects
de-oxygenated blood from the body into the right
atrium and then via the right ventricle pumps it into
the lungs so that carbon dioxide can be dropped off
and oxygen picked up.
The left side of the heart collects oxygenated blood
from the lungs into the left atria. From the left atrium
the blood moves to the left ventricle which pumps it
out to supply oxygen to the body.
Introduction

3. It collects deoxygenated blood
returning from the body (through
vena cava) and the forces it into the
right ventricle through the tricuspid
valve
Right Atrium

4. It collects oxygenated blood
returning from the lungs and then
forces it into the left ventricle
through the mitral valve or bicuspid
valve.
Left Atrium

5. It collects deoxygenated blood
from the right atrium and then
forces it into the lungs through
the pulmonary valve.
Right Ventricle

6. It is the largest and the
strongest chamber in the heart.
It pushes blood through the
aortic valve and into the body.
Left Ventricle

7. Valves of Heart
Pulmonary
Valve
Tricuspid
Valve
Bicuspid
Valve
Aortic
Valve
Tricuspid Valve
It helps blood flow in the correct direction from the right
atrium to the right ventricle.
Bicuspid Valve
The valve allows blood to flow from the left ventricle
(pumping chamber) to the aorta and prevents blood from
flowing backward.
Pulmonary Valve
The pulmonary valve normally acts like a one-way door from
your heart's right ventricle to the lungs. Blood flows from the
right ventricle through the pulmonary valve to the
pulmonary artery and then into the lungs, where it picks up
oxygen to deliver to your body.
Aortic Valve
The aortic valve helps keep blood flowing in the correct
direction through the heart. A damaged or diseased aortic
valve can affect blood flow to the rest of the heart and body

8. Vessels of Heart
Aorta
It is the largest artery and carries oxygenated blood
from the heart to the rest of body.
Pulmonary
Veins
Interior Vena
Cava
Pulmonary
Arteries
Superior Vena
Cava
Aorta
Superior Vena Cava
Deoxygenated blood from the upper part of the body
returns to the heart through the superior vena cava.
Inferior Vena Cava
Deoxygenated blood from the lower part of the body
returns to the heart through the inferior vena cava.
Pulmonary Arteries
They carry de-oxygenated blood from the heart to the
lungs to pick up oxygen.
Pulmonary Veins
They carry oxygenated blood from the lungs back to
the heart.
