Physiology Of The Respiratory System Basicmedical Key Since the conversion of glucose to atp produces carbon dioxide as a waste, carbon dioxide originates at the cells of the body and takes the same journey in reverse to be eliminated form the body when you inhale. the processes of the respiratory system are pulmonary ventilation, external respiration, transport of gases, internal respiration, and. Respiratory zone: respiratory bronchioles, alveoli. breathing cycle. inspiration diaphragm contracts and pulls down, intercostal muscles contract and expand the rib cage > air enters the lungs. expiration diaphragm relaxes and goes up, intercostal muscles relax and rib cage collapses > air exits the lungs.
Ppt Respiratory System Powerpoint Presentation Free Download Id Pulmonary ventilation comprises two major steps: inspiration and expiration. inspiration is the process that causes air to enter the lungs, and expiration is the process that causes air to leave the lungs (figure 22.3.3). a respiratory cycle is one sequence of inspiration and expiration. Respiration is a metabolic process that occurs in all organisms. it is a biochemical process that occurs within the cells of organisms. in this process, the energy (atp adenosine triphosphate) is produced by the breakdown of glucose which is further used by cells to perform various functions. every living species, from a single celled organism. The respiratory rhythm and the length of each phase of respiration are set by reciprocal stimulatory and inhibitory interconnection of these brain stem neurons. an important characteristic of the human respiratory system is its ability to adjust breathing patterns to changes in both the internal and the external environment. Mechanics of breathing. the processes of inspiration (breathing in) and expiration (breathing out) are vital for providing oxygen to tissues and removing carbon dioxide from the body. inspiration occurs via active contraction of muscles – such as the diaphragm – whereas expiration tends to be passive, unless it is forced.

Figure 39.9.1 39.9. 1: inhalation and exhalation: the lungs, chest wall, and diaphragm are all involved in respiration, both (a) inhalation and (b) expiration. during this process, the chest wall expands out and away from the lungs. the lungs are elastic; therefore, when air fills the lungs, the elastic recoil within the tissues of the lung. Aerobic respiration is the process of turning food into a form of chemical energy cells can use. it requires oxygen. aerobic respiration is a complex, multi stage process that efficiently produces atp, the primary energy currency for cells. respiration is a fundamental process that occurs in cells that extracts energy from organic molecules.
