3. Structure of the Heart
Chambers of the heart
The Atrium
Upper two chambers
Divided into the left Atria an the Right Atria
Brings in Blood from the Veins
The Ventricles
Lower two chambers
Divided into left ventricle and right ventricle
Pumps in blood into the arteries
4. Structure (Contd…)
Valves of the Heart
AtrioVentricular valves
Lie between the atrium
and the ventricles
Semilunar valves
Lie between the
ventricles and the
arteries
5. Functioning of the heart
Left hand side of the heart brings in oxygen rich blood, red color in
the animation
Right hand side of the heart brings in oxygen deficient blood, blue in color in
the animation
Cardiac cycle
Two Phases :
Diastole Phase
* Both atria and the ventricles are relaxed
Systole Phase
* Chambers contract to push blood
The heart beat cycle
Atrium brings in blood from the veins and expands to fill it up
Atrium then contracts and pushes blood into the ventricles, Ventricles expand
The atrioventricular valves close in order to prevent backward flow of
blood
6. The Chambers expanding and Contracting
Three snapshots of the heart were created using polygon
deformers with simple push, pull and smooth operators
Atrium Expanded
Atrium Contracted and Ventricles expanded
Ventricles contracted
Original mesh in made to blend into these shapes using blend
deformer tool
The heart alternates between these three cycles followed by a
small amount of rest time and then repeats
7. The blood flow
Blood is made up of tiny particles made to flow along
curves inside the heart
Each emitter emit 15,000 particles per second, 7 such
emitters
Bump shaded texture to each particle to give the blood
effect
The pulsating effect is achieved throughout turning the
emitters on and off at regular intervals
Valves opening
Made to rotate along its pivot
Used polygon deformers and blend shapes to show their
movement
13. Future work
Have the blood particles collide with the wall of the
heart for more accuracy and precision
Make the blood deform the heart
Have the valves react with the movement of the
blood

15. The human heart is a four-chambered muscular organ, shaped and
sized roughly like a man's closed fist with two-thirds of the mass to
the left of midline. The heart is enclosed in a pericardial sac that is
lined with the parietal layers of a serous membrane. The visceral
layer of the serous membrane forms the epicardium.
Layers of the Heart Wall
Three layers of tissue form the heart wall. The outer layer of the
heart wall is the epicardium, the middle layer is the myocardium,
and the inner layer is the endocardium.
Chambers of the Heart
The internal cavity of the heart is divided into four chambers:
Right atrium
Right ventricle
Left atrium
Left ventricle
16. The two atria are thin-walled chambers that receive blood
from the veins. The two ventricles are thick-walled
chambers that forcefully pump blood out of the heart.
Differences in thickness of the heart chamber walls are
due to variations in the amount of myocardium present,
which reflects the amount of force each chamber is
required to generate.
The right atrium receives deoxygenated blood from
systemic veins; the left atrium receives oxygenated blood
from the pulmonary veins.
Valves of the Heart

For HEART
17. Pumps need a set of valves to keep the fluid flowing in one direction and the
heart is no exception. The heart has two types of valves that keep the blood
flowing in the correct direction. The valves between the atria and ventricles
are called atrioventricular valves (also called cuspid valves), while those at
the bases of the large vessels leaving the ventricles are called semi lunar
valves.
The right atrioventricular valve is the tricuspid valve. The left atrioventricular
valve is the bicuspid, or mitral, valve. The valve between the right ventricle
and pulmonary trunk is the pulmonary semi lunar valve. The valve between
the left ventricle and the aorta is the aortic semi lunar valve.
When the ventricles contract, atrioventricular valves close to prevent blood
from flowing back into the atria. When the ventricles relax, semi lunar valves
close to prevent blood from flowing back into the ventricles.
18. Pathway of Blood through the Heart
While it is convenient to describe the flow of blood through the right side of the
heart and then through the left side, it is important to realize that both atria
contract at the same time and both ventricles contract at the same time. The
heart works as two pumps, one on the right and one on the left, working
simultaneously. Blood flows from the right atrium to the right ventricle, and then
is pumped to the lungs to receive oxygen. From the lungs, the blood flows to the
left atrium, then to the left ventricle. From there it is pumped to the systemic
circulation.
Blood Supply to the Myocardium
The myocardium of the heart wall is a working muscle that needs a continuous
supply of oxygen and nutrients to function with efficiency. For this reason,
cardiac muscle has an extensive network of blood vessels to bring oxygen to the
contracting cells and to remove waste products.
The right and left coronary arteries, branches of the ascending aorta, supply
blood to the walls of the myocardium. After blood passes through the capillaries
in the myocardium, it enters a system of cardiac (coronary) veins. Most of the
cardiac veins drain into the coronary sinus, which opens into the right atrium .

24. • Saponin Ginostemma Pentafilumm
Since long time it has been widely used as a herb of longitivity for life. It has
been proven to be main constituent of Ginostemma Pentafilumm. It inhibits
the coagulation of platelets in blood. It protects blood vessels from hardening
promotes better blood circulation and protects from heart disease. It provides
spiritual peace. It can be continued for longer duration. Protects organs from
oxidation and radical attacks and maintains normal conditions of cell.
Minimizing the amount of lipid found within the blood by regulating the
production of oxidized fatty acid and blood vessels blockage in the brain and
coronary arteries. Enhanced blood supply to the coronary arteries and
overcome oxygen deficiency in heart. It is the most suitable product for high
blood pressure, cardio. Vascular disease and patients suffering from other
cardiac problems.

• put 5g of rice into each of the 3 glasses
• then add few drops of iodine ,a powerful oxidation chemical ,then
wait for 3 minutes for oxidation
•Then add 15 ml water into the 3 glasses
• open 2 Anti-oxidant ,Cardio System and put into 2 of the 3 glass
respectively ,leave 1 of the 3 glass with water only
• stir,then see the rice color in the glass with antixidant and cardio
system.They are becoming white again, But the rice in the glass
with only water is brown, due to detoxification
