Medical Subject Headings (MeSH): Circulatory and Respiratory Physiological Phenomena

Circulatory and respiratory physiological phenomena are processes that occur within the body to support the circulation of blood and the exchange of gases, such as oxygen and carbon dioxide. These processes are essential for maintaining the health and function of the body’s tissues and organs, and are regulated by the circulatory and respiratory systems.

Circulatory physiological phenomena in healthcare include:

Blood flow: The circulation of blood through the body is essential for delivering oxygen and nutrients to tissues and for removing waste products.

Blood pressure: The pressure of the blood flowing through the body’s vessels is regulated to ensure that the tissues and organs receive an adequate supply of oxygen and nutrients.

Heart rate: The rate at which the heart beats is regulated to ensure that the body’s tissues and organs receive an adequate supply of blood.

Respiratory physiological phenomena in healthcare include:

Breathing: The exchange of gases between the lungs and the body’s tissues is essential for maintaining the body’s oxygen supply and removing waste products, such as carbon dioxide.

Gas exchange: The transfer of oxygen and carbon dioxide between the blood and the body’s tissues occurs through the process of diffusion.

Respiratory rate: The rate at which a person breathes is regulated to ensure that the body’s tissues and organs receive an adequate supply of oxygen.
