The respiratory system is responsible for obtaining oxygen and getting rid of carbon dioxide, and aiding in speech production and in sensing odors. Anatomy and Physiology of Respiratory System | Main Parts. Inhalation causes an upward deflection of a scan line and exhalation causes a downward deflection. Human Anatomy and Physiology: CCSF Home | Biology Home | Site Map: Home. The airways of the body are commonly divided into two sections: a)The upper respiratory tract and b) The lower respiratory tract. PLAY. Air flows in and out of each lung through these, After entering the lung, the primary (1 percent) bronchi divide into these. Carbon dioxide is exhaled and oxygen is inhaled through the respiratory system, which includes muscles to move air into and out of the lungs, passageways through which air moves, and microscopic gas exchange surfaces covered by capillaries. exchange of gases between alveoli and blood, step 3 of respiration - rate of gas exchange, O2 and CO2 transport, hemoglobin, regulation, exchange gases between systemic capillaries and tissue cells, supplies cellular respiration to make ATP, pressures ____ as size of container holding set amount decreases, movement of air into and out of lungs, pressure of a gas in a closed container is inversely proportional to the volume of the container. Quizzes. To play this quiz, please finish editing it. Links. Along the cillia are many binding sites for odorants. Because it is located near the body surface, the vestibule region is frequently exposed to destructive agents. Quizzes.

To ensure the best experience, please update your browser. Edit. You should be able to explain the process of breathing: what are the steps from breathing in to breathing out (name them!) Respiratory system (Systema respiratorum) The respiratory system, also called the pulmonary system, consists of several organs that function as a whole to oxygenate the body through the process of respiration (breathing).This process involves inhaling air and conducting it to the lungs where gas exchange occurs, in which oxygen is extracted from the air, and carbon dioxide expelled from the … From a functional perspective, the respiratory system can be divided into two major areas: the conducting zone and the respiratory zone. Created by. Grass Home. Several non-motile cillia extend from each bulbous tip.

It also contains some questions from the "Fetal" case unit (hemoglobin dissociation curve, surfactant questions). Gravity. Surrounding the receptors are many elongated supporting cells or sustentacular cells, Several open, air-filled chambers that are present in the bones surrounding the nasal cavity, The sinuses in the bones right above the orbits, Mucosa-lined air spaces within the bones of the face and skull. Anatomy and Physiology of the Nose.
