The cardiovascular system can be thought of as the transport system of the body.

This system has three main components: the heart, the blood vessel and the blood itself.

But what we are going to focus now is all about heart! Are you ready to learn?

Heart is the system’s pump and the blood vessels are like the delivery routes.

Blood can be thought of as a fluid which contains the oxygen and nutrients the body needs and carries the wastes which need to be removed.

What are the Functions of the Heart ?

Right-Hand Side of the Heart

The right-hand side of the heart receives de-oxygenated blood from the body tissues (from the upper- and lower-body via the superior vena cava and the inferior vena cava, respectively) into the right atrium. This de-oxygenated blood passes through the tricuspid valve into the right ventricle. This blood is then pumped under higher pressure from the right ventricle to the lungs via the pulmonary artery.

 

 

Left-Hand Side of the Heart

The left-hand side of the heart receives oxygenated blood from the lungs (via the pulmonary veins) into the left atrium. This oxygenated blood then passes through the bicuspid valve into the left ventricle. It is then pumped to the aorta under greater pressure (as explained below). This higher pressure ensures that the oxygenated blood leaving the heart via the aorta is effectively delivered to other parts of the body via the vascular system of blood vessels (incl. arteries, arterioles, and capillaries).

Conclusion

Image result for conclusion background

The heart and blood vessels form an intricate network throughout the human body. 

The anatomy of the four-chambered heart is central to the network and functions to maintain blood moving throughout the body. 

Arteries, capillaries, and veins work in conjunction to keep all tissues healthy by providing oxygen and other nutrients while removing carbon dioxide and other waste through continuous blood flow. 

As the body encounters parasites or infections, the immune response is triggered and the appropriate blood components initiate a response to remove the undesirable items. 

In cases of mutations or injuries to the circulatory system, other systems in the body can be affected, thus demonstrating the importance of how the body requires the interaction of all the systems to maintain proper function.
