There are 3 different kinds of blood vessels within the body. These include:

-Arteries

-Veins

-Capillaries

These structures function to transport blood throughout the body.

# data[].attributes.body
The heart contains four different valves including:

-Tricuspid Valve

-Pulmonary Valve

-Mitral Valve

-Aortic Valve

These are responsible for controlling the flow of blood within the heart.

# data[].attributes.body
The heart is divided into four different chambers, these are:

-Right Atrium

-Right Ventricle

-Left Atrium

-Left Ventricle

The atria are the two upper chambers whereas the ventricles are the two lower chambers.

# data[].attributes.body
The heart's chambers are divided by:

-Interatrial Septum (Separates the Atria)

-Interventricular septum (Separates the Ventricles)

The walls of the heart are also made up of three different layers:

-Endocardium: the innermost lining as well as heart valves

-Myocardium: Thick, muscular middle layer of the heart wall

-Pericardium: Membranous sac that surrounds the outside of the heart

Deoxygenated blood from the body enters the heart through here

*A valve is a flap that prevents the backflow of blood within the heart

# data[].attributes.body
This is where the deoxygenated blood will be pumped to the lungs in order to obtain oxygen

# data[].attributes.body
This is where the deoxygenated blood picks up oxygen and drops off carbon dioxide

# data[].attributes.body
The oxygenated blood has now re-entered the heart to be sent off to different parts of the body

# data[].attributes.body
This is where the blood will exist the heart in order to be sent to all different parts of the body

# data[].attributes.body
Oxygenated blood will reach arteries all over the body

# data[].attributes.body
The Capillaries are where oxygen and nutrients will be able to go from the blood to the body by passing through their walls

# data[].attributes.body
The veins will collect deoxygenated blood and send it back to the Superior and Inferior Vena Cava to begin the process again
