INTERNAL RESPIRATION Meaning and
Definition
-
Internal respiration is a physiological process that takes place inside the body, specifically at the cellular level, where exchange of gases occurs between the cells and the surrounding tissues. It is an essential component of the broader process of respiration, which includes both external and internal phases. Internal respiration is also referred to as cellular respiration or tissue respiration.
During internal respiration, oxygen (O2) is delivered to the cells through the bloodstream, where it is utilized in the process of cellular metabolism. This metabolic process involves the breaking down of glucose to produce energy in the form of adenosine triphosphate (ATP), which is necessary for the cells to perform their functions. Simultaneously, carbon dioxide (CO2), a waste product of cellular metabolism, is produced and released into the bloodstream to be transported back to the lungs for elimination.
Internal respiration occurs in all living cells, including those in various organs and tissues such as the muscles, brain, and heart. It ensures that oxygen is continuously supplied to the cells and that waste carbon dioxide is efficiently removed from the cellular environment. The process is tightly regulated by the body's respiratory and circulatory systems, with the lungs and heart playing crucial roles in facilitating the exchange of gases between the tissues and the external environment.
Overall, internal respiration is a dynamic process that enables cells to receive the oxygen necessary for their survival while eliminating the waste carbon dioxide produced during metabolism. It is an integral part of the body's ability to maintain homeostasis and support the proper functioning of tissues and organs.

Etymology of INTERNAL RESPIRATION
The word "internal respiration" is composed of two terms: "internal" and "respiration".
The term "internal" is derived from the Latin word "internus", which means "inward" or "inner". In this context, it refers to something happening or situated within the body.
The term "respiration" comes from the Latin word "respirare", which means "to breathe". It is a combination of the prefix "re-", meaning "again", and "spirare", meaning "to breathe". Respiration refers to the process of taking in oxygen and releasing carbon dioxide, typically used to describe the overall process of breathing.
Therefore, "internal respiration" specifically refers to the process of oxygen exchange at the cellular level within an organism's body. It is often used to distinguish cellular respiration (metabolic process) from the breathing process at the organism level (external respiration or pulmonary respiration).
