It is also called the circulatory or cardiovascular system. This system transports oxygen, nutrients and other vital substances to all parts of the body. This system consists of three components: the blood vessels, heart and blood. Through arteries, the heart sends oxygen-rich blood throughout the body. Veins then return the oxygen-depleted blood to the heart. In contrast, the respiratory system is responsible for exchanging gases with the surrounding environment. The respiratory system is made up of the lungs and airways as well as breathing muscles. The inhalation process involves oxygen intake, while the exhalation process is used to expel carbon dioxide.
As oxygen is necessary for the proper functioning of the cardiovascular system, they are interconnected. Asthma, pneumonia or chronic obstructive lung disease (COPD) can cause the oxygen level to drop, which in turn can affect the cardiovascular system. In the opposite direction, disruptions to the cardiovascular system such as coronary artery or heart failure can cause a reduction in oxygen and blood delivery to the lungs. This can affect the respiratory system.
Patient characteristics, such as weight, age, gender, and medical histories, can be critical in the diagnosis and treatment of disease. Smokers are more likely to develop respiratory disease than older adults. A person’s race and ethnicity can have an impact on the diagnosis and treatment of a disease. African Americans and Native Americans both have an elevated risk of hypertension and cardiovascular disease.
Conclusion: Understanding the interdependence of respiratory and cardiovascular systems is crucial for diagnosis and treatment. It is important to also consider the patient’s characteristics and demographics when treating and assessing diseases that affect these systems.
