The human heart is an organ within the body that pumps blood throughout the body and
this ensures that there is enough oxygen supply and nutrients to the body tissues. Moreover, it is
essential in doing away with carbon dioxide and other waste within the body. The human heart
has four chambers and these include the two upper chambers and the two lower chambers. The
human heart consist of specific blood vessels. The blood vessels include the arteries which are
known to carry blood which is oxygenated from the heart to the body tissues. The heart is made
up of several capillaries that are known to be within the blood vessels considered to be thin and
are responsible for making connection between the arteries and the veins. Moreover, they have
thin walls that enable them to allow movement of nutrients, oxygen, and carbon dioxide together
with the other wastes that exist within our organ cells (Willis, 2016).
Furthermore, veins are also found in the human heart, and they are responsible for taking
the blood back to the heart, and the blood is known to have low oxygen content. They contain the
waste products that are supposed to be removed from the body. The heart contains a superior
vena cava that transports blood from the head or even the arms to the heart. The heart various
muscles, especially at the on the walls of the heart. The strong muscular walls of the heart are
known to contract to allow blood to be pumped to the rest of the organs within the body. There
are coronary arteries that are responsible for providing blood rich in oxygen to the heart muscle.

Furthermore, the heart is known to be four-chambered, whereby it is dived into the left
and even the right side using the muscular wall known as the septum. Moreover, this is according
to "The Works of William Harvey" in the topic "The heart and soul of change". Furthermore,
both sides are further divided into two chambers. The top chamber is known as the atria, which is
responsible for receiving the blood that comes from the veins (Hubble, 2016). The bottom
chambers are known as the ventricles, and they are responsible for pumping blood to the arteries.
Furthermore, both the chambers are known to work together by contracting and even relaxing to
pump blood out of the heart. Moreover, the heart is made up of four valves, including the
tricuspid valve, pulmonic valve, Mitral valve and the Aortic valve.
Blood goes ahead to move from the right atrium straight to the right ventricle, and this
takes place through the tricuspid valve. The tricuspid valve closes when the ventricle gets
occupied. When the ventricle contracts, the blood is transported to the pulmonary artery before
going to the lungs using the pulmonic valve. Moreover, the blood is oxygenated before being
transported back to the left atrium as it passes through the pulmonary veins. Blood flows to the
left ventricle by the time the atrium contracts. When the ventricle contracts, the blood moves
from the heart straight to the body.
