Which of the following is NOT a function of the respiratory system? Select one: a. To facilitate the exchange of gases between the air and the blood.
What is the function of the movement of gas molecules within alveoli?
C) movement of gas molecules within alveoli creates electrical charges that attract each other.
What happens to the volume of a gas at a constant temperature?
A) at a constant temperature, the volume of a gas varies inversely with the pressure.
Which volume increases as the diaphragm contracts during inspiration?
D) thoracic volume increases as the diaphragm contracts during inspiration.
Which nerve stimulates contraction of the diaphragm?
A) the phrenic nerve stimulates contraction of the diaphragm.
How does oxygen get into the lungs?
Inside the lungs, oxygen is exchanged for carbon dioxide waste through the process called external respiration. This respiratory process takes place through hundreds of millions of microscopic sacs called alveoli. Oxygen from inhaled air diffuses from the alveoli into pulmonary capillaries surrounding them.
What are the functions of the respiratory system?
The following are the five key functions of the respiratory system. 1. Inhalation and Exhalation Are Pulmonary Ventilation—That’ s Breathing. The respiratory system aids in breathing, also called pulmonary ventilation. In pulmonary ventilation, air is inhaled through the nasal and oral cavities (the nose and mouth).
How does pulmonary ventilation work?
In pulmonary ventilation, air is inhaled through the nasal and oral cavities (the nose and mouth). It moves through the pharynx, larynx, and trachea into the lungs. Then air is exhaled, flowing back through the same pathway. Changes to the volume and air pressure in the lungs trigger pulmonary ventilation.
What happens when you exhale?
During exhalation, air passes from the lungs through the larynx, or “voice box.”. When we speak, muscles in the larynx move the arytenoid cartilages. The arytenoid cartilages push the vocal cords, or vocal folds, together. When the cords are pushed together, air passing between them makes them vibrate, creating sound.
How does olfaction work?
The process of olfaction begins with olfactory fibers that line the nasal cavities inside the nose. As air enters the cavities, some chemicals in the air bind to and activate nervous system receptors on the cilia. This stimulus sends a signal to the brain: neurons take the signal from the nasal cavities through openings in the ethmoid bone, and then to the olfactory bulbs. The signal then travels from the olfactory bulbs, along cranial nerve 1, to the olfactory area of the cerebral cortex.
Where does carbon dioxide diffuse?
It diffuses through the capillary walls into body tissues. Meanwhile, carbon dioxide diffuses from the tissues into red blood cells and plasma. The deoxygenated blood carries the carbon dioxide back to the lungs for release. All 3D models in the page have loaded.
Which cell brings oxygen to the lungs?
Red blood cell. Red blood cells carry inhaled oxygen to the body's tissues and bring carbon dioxide back to the lungs to be exhaled. 4. Air Vibrating the Vocal Cords Creates Sound. Phonation is the creation of sound by structures in the upper respiratory tract of the respiratory system.
What is the function of the movement of gas molecules within alveoli?
C) movement of gas molecules within alveoli creates electrical charges that attract each other.
What happens to the volume of a gas at a constant temperature?
A) at a constant temperature, the volume of a gas varies inversely with the pressure.
Which volume increases as the diaphragm contracts during inspiration?
D) thoracic volume increases as the diaphragm contracts during inspiration.
Which nerve stimulates contraction of the diaphragm?
A) the phrenic nerve stimulates contraction of the diaphragm.
