May 27, 2024 · Human respiratory system, the system in humans that takes up oxygen and expels carbon dioxide. The major organs of the respiratory system include the nose, pharynx, larynx, trachea, bronchi, lungs, and diaphragm.
The respiratory system. The process of physiological respiration includes two major parts: external respiration and internal respiration. External respiration, also known as breathing, involves both bringing air into the lungs (inhalation) and releasing air to the atmosphere (exhalation).
In humans and other mammals, the anatomy of a typical respiratory system is the respiratory tract. The tract is divided into an upper and a lower respiratory tract. The upper tract includes the nose, nasal cavities, sinuses, pharynx and the part of the larynx above the vocal folds.
Aug 31, 2023 · Breathing is one of the four components of respiration, the other three being gas diffusion, gas transport and regulation. The pathway towards the lungs is provided by airways and together, these components form the respiratory system, which is located inside the thoracic or chest cavity.
Respiration by the respiratory system supplies the oxygen needed by cells for aerobic cellular respiration and removes the carbon dioxide produced by cells during cellular respiration. Respiration by the respiratory system actually involves two subsidiary processes.
In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction to the surrounding environment.
Define respiratory rate. Outline the mechanisms behind the control of breathing. Describe the respiratory centers of the medulla oblongata. Describe the respiratory centers of the pons. Discuss factors that can influence the respiratory rate.
May 27, 2024 · Understanding the mechanics of human respiration. Overview of the mechanics of the lungs and rib and diaphragm muscles involved in human respiration. (more) See all videos for this article. Alveolar pressure fluctuations are caused by expansion and contraction of the lungs resulting from tensing and relaxing of the muscles of the chest and abdomen.
The term respiration denotes the exchange of the respiratory gases (oxygen and carbon dioxide) between the organism and the medium in which it lives and between the cells of the body and the tissue fluid that bathes them.
