The Human Respiratory System: Anatomy and Functions
Explore the human respiratory system, its anatomy, functions, and physiological processes. Learn about gas exchange, airways, and the importance of respiration in maintaining health. Discover the organs and tissues involved in respiration, such as the mouth, nose, pharynx, and trachea. Dive into the role of the respiratory system in gas exchange, ventilation, and cellular respiration. Uncover the significance of warm air humidification, filtration of harmful substances, and protection against irritants.

Human respiratory system The main function of the human respiratory system is gas- ______________. Respiratory events include: The movement of air in and out of the lungs, commonly called breathing or ventilation. The exchange of gas between the lungs and blood (external respiration). The exchange of gases between the blood and body cells (internal respiration). The oxygen utilization and CO2 production (cellular respiration).
Other physiologic functions of the Respiratory System The respiratory system: 1. Allows the patient to talk and to _______________. 2. Warms air to match the body temperature and moisturizes it to the humidity level the body needs. 3. _______________ the airways from harmful substances and irritants. 4. Respiration is both macroscopic and microscopic explain what this means.

What is the anatomy of the human respiratory system? Many different components (organs and tissues) comprise the respiratory system. Start with the airways: 1. Mouth and nose: Openings that pull air from outside your body into your respiratory system. Internal hairs in the nostrils begin to ______________ inhaled air. 2. Nasal cavity is the hollow space behind the nose. This transports air to the pharynx, and the mucous lining helps to filter, warm, and moisten the incoming air. 3. Sinuses: Hollow areas between the bones in your head that help regulate the temperature and humidity of the air you inhale. Also reduces the weight of the skull and adds resonance to voice. 4. Pharynx (throat): Tube that delivers air from your mouth and nose to the trachea (windpipe), which distinguishes air from food/drink entering your esophagus. Located ___________ to the oral cavity and __________ the nasal cavity and larynx.
What is the anatomy of the human respiratory system? 5. Larynx: this is the voicebox and is an enlarged area superior to the trachea. It is the passageway for air and prevents foreign material from entering the lungs and contains the vocal cords. 6. Trachea or the windpipe : Flexible tube and passageway connecting your throat and lungs, specifically the larynx to the _____________ tree. 7. Bronchial tree: Beginning with the bronchial tubes, located at the bottom of your trachea, connecting into the branches of each lung and leading to the alveoli. 8. Lungs: The soft, cone-shaped organs occupying the thoracic cavity (along with the heart), which remove oxygen from air and pass it into your bloodstream. The lungs contain the bronchial tree, the alveoli, blood vessels, connective tissue, lymphatic vessels, and the nerves of the lower respiratory tract.
The bronchial tree Continue work on the do now or on the final exam skit. We will evaluate the anatomy and physiology of the bronchial tree tomorrow.
