The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other harmful materials.
The organ of cardiac muscle, also known as the heart, is comprised of two atria and two ventricles. There are additionally four valves in our heart that prevent the backflow of blood and keep the blood flowing in one direction. Two valves are found in the heart and two are found in the major arteries in the heart. Those major arteries are the aorta and the pulmonary artery. The human heart is made up of four-chambers that is separated into the right half and the left half which each have their own atrium. The atrium on each side of the heart...

The circulatory and respiratory system are two systems that both play major roles in our everyday lives. Both systems have important responsibilities and have essential jobs to the human body. The circulatory system is the system that circulates the blood to the rest of the body while the respiratory system is the system that transports the blood to the circulatory system. The circulatory system provides the body with clean blood and transports the bad blood to the lungs to be cleaned of carbon dioxide. The respiratory system cleans the blood in the lungs and transports it back to the heart to be redistributed to the rest of the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other harmful materials.

The structure of the blood vessels are similar to the structure of the heart.
