The Human Anatomy and Physiology course is designed to introduce students pursuing careers in the allied health field to the anatomy and physiology of the human body. Skeletal Muscle Anatomy Quizlet. 3. Lungs (alveoli); millions of thin-walled, microscopic air sacs in lungs; exchange gases with the bloodstream through the alveolar wall and then flows back out, Located outside of chest (nose, pharynx, larynx), Located in thorax (trachea, bronchi, and lungs), Nose, pharynx, larynx, trachea, bronchi, bronchioles, alveoli/lung, pleura, 3 nasal conchae; project from lateral walls toward septum; cleans, warms and moistens air, Warms, cleanses, and humidifies inhaled air; detects odors in the air stream; serves as a resonating chamber that amplifies the voice, A muscular funnel extending about 13 cm (5 in) from the nasal cavity to the larynx, posterior to nasal cavity and above soft palate; receives auditory (pharyngotympanic/eustachian) tubes and contains pharyngeal tonsil, Space between soft palate and epiglottis; contains palantine tonsils; shared by respiratory and digestive system, Epiglottis to espohagus; food, drink and air pass through here; shared by respiratory and digestive system, Primary is to keep food and drink out of airway; additional role in speech, Epiglottis; thyroid cartilage (adam's apple); vestibular folds; vocal cords (glottis), Flap of tissue that guards the superior opening of the larynx; at rest, stand almost vertically; during swallowing, closes airway like a trap door and directs food to the esophagus behind it, Largest laryngeal prominence (adam's apple); shield-shaped; testosterone stimulates growth, larger in males, Produce sound when air passes between them; loudness determined by the ofrce of air passing between the vocal cords, the vocal cords and the opening between them, A rigid tube about 4.5 inches long and 1 inch in diameter; anterior to esophagus; supported by 16-20 C-shaped rings of hyaline cartilage; reinforces the trachea and keeps it from collapsing when inhaling; opening in rings face posteriorly toward esophagus; makes mucus that is beat upward by cilia, Has broad, concave base, rests on the diaphragm, and has a blunt peak called the apex projecting slightly above the clavicle, slit through which the lung receives the main bronchus, blood vessels, lymphatics and nerves, Shorter and more vertical, allows for easier entry of foreign objects, a branching system of air tubes in each lung; from main bronchus to 65,000 terminal bronchioles, Supported by C-shaped hyaline cartilage rings; right bronchus slightly wider and more vertical than left, Lack cartilage; 1 mm or less; well-developed layer of smooth muscle; branch into smaller bronchioles with alveoli budding from their walls, 150 million in each lung; Primary function is gas exchange, Adheres to mediastinum, inner surface of the rib cage, and superior surface of the diaphragm, Potential space between pleura; normally no room between the membranes, but contains a film of slippery pleural fluid, Syngerist to diaphragm; between ribs; stiffen the thoracic cage during respiration and prevent it from caving inward when the diaphragm descends; contribute to enlargement and contraction of thoracic cage, Internal and external intercostal muscles, Prime mover of respiration; contraction flattens diaphragm, enlarging thoracic cavity and pulling air into lungs; relaxation allows diaphragm to bulge upward again, compressing the lungs and expelling the air, Reduce friction; create pressure gradient = lower pressure than atmospheric pressure; assists lung inflation; compartmentalization= prevents spread of infection from one organ in mediastinum to others, On the medial side of the lungs (mainly the left) for insertion of heart, Consists of a repetitive cucle: one cycle of inspiration (inhaling) and expiration (exhaling), ...air pressure within lungs and outside body, A passive process achieved by the elasticity of the lungs and thoracic cage, Automatic, unconscious cycle of breathing is controlled by three pairs of respiratory centers in the reticular formation of the medulla oblongata and the pons, Neurons in the brain stem medulla oblongata and pons control unconscious breathing, Fibers of phrenic never supply diaphragm; intercostal nerves supply intercostal muscles, ...available for gas exchange; not all inhaled air gets there, Volume of air inhaled and exhaled in one cycle during quite breathing (500ml), Air excess of tidal volume that can be inhaled with maximum effort, Air in excess of tidal volume that can be exhaled with maximum effort, 1,300ml that cannot be exhaled with max effort; air remaining in alveoli after expiration; prevents collapsed lung, Total amount of air that can be inhaled and then exhaled with max effort; important measure of pulmonary health, labored, gasping breathing; shortness of breath, Air filled cavities that aid in sound production and lighten the bones of the skull, Located along the walls of the back of the throat, Also known as false vocal cords because they do not aid in vocal ability. As the volume of the thoracic cavity increases due to contraction of the muscles of inspiration, The drop in pressure in the alveoli to below atmospheric pressure will. Impulses from the primary respiratory center to the respiratory muscles will initiate. Write. Which muscles contract for a forced expiration? Do you know all there is to this specific system? here it splits into two branches called bronchi. The Respiratory System. It is responsible for the passage of air into our body, which is the source of life energy. What principle causes the exchange of oxygen and carbon dioxide between the capillaries and the alveoli? The respiratory system is the organs and other parts of your body involved in breathing, when you exchange oxygen and carbon dioxide. Oxygen supplier. These parts work together to move oxygen throughout … 5 - the axial skeleton: How about the bones of the axial skeleton?. After bicarbonate ion is produced in the red blood cell, it moves into the plasma and is replace by, If carbon dioxide levels in the blood increase, pH will ___ , causing ______, degenerative disease affecting respiratory membrane, ______ is a bacterial infection of the upper respiratory tract. Air remaining in alveoli after a deep breath, Maximum volume of air moved in and out during a single deep breath, volume of air moved in/out during normal breath. 4. 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 … Two pairs of vocal folds are found in the larynx.
