Circulatory System and Pathway of Blood
through the Heart
Amoeba Sisters
Introduction to the Circulatory System
In this introduction, we will discuss the functions of the
circulatory system and the pathway of blood through the heart.
Whilst there are extensive textbooks on the circulatory system,
we will focus on basics. Essentially, blood is crucial as it helps
transport glucose and gases throughout the body.
The human heart anatomy divides the heart into two separate
partitions. The right side pumps deoxygenated blood, while the
left side pumps oxygenated blood. However, some congenital
heart conditions may cause this oxygenated and deoxygenated
blood to mix.
To get the blood from the tip of your toes to your heart, the
heart needs to have its own blood supply. It is the coronary
arteries that supply the heart with oxygen and glucose. These
arteries branch off the aorta and deliver blood into the
capillaries, which then deliver oxygen to the heart.
Heart conditions can change the normal flow of blood, leading
to various health problems.
The circulatory system is an essential part of the body
which consists of the heart, blood vessels, and blood. It
comprises two circuits responsible for carrying blood
throughout the entire body.
The pulmonary circuit carries deoxygenated blood to the
lungs for the exchange of carbon dioxide and oxygen,
after which oxygenated blood returns to the heart. The
heart then pumps this newly oxygenated blood around
the body, collecting nutrients, and waste products.
These substances filter into the liver, where they are
processed.
