Main Functions
What is the most common function of the respiratory system?
Breathing
What is the most known part of the Respiratory system?
The lungs
What is the first step in resperation?
Pulmonary Ventilation.
How do the lungs and heart work together?
The lungs re oxygenate blood.
What is the chronic, long-term condition that inflames and narrows the airways, causing wheezing, chest tightness, shortness of breath, and coughing called?
Asthma
What is the second most common use of the Respiratory system?
Regulation of blood pH
What is the part of the Respiratory system that transports air in and out of the lungs during breathing?
The trachea.
What is the second step in resperation?
External Respiration.
How do the diaphragm and brain work together?
The brain sends signals to the diaphragm to regulate blood pH.
What is a serious malignancy characterized by the uncontrolled growth of abnormal cells in the lung tissue, heavily linked to tobacco smoke and environmental carcinogens called?
Lung cancer.
What is the third most common use of the Respiratory system?
Protection against particles.
What part of the Respiratory system serves as the main air passages that transports, warms, moistens, and cleans air as it travels from your windpipe into and out of your lungs?
The bronchi
What is the third step in resperation?
Transport of Gases.
How do muscles and the lungs work together?
The muscles contract to push air in and out of the lungs.
What is a contagious and potentially fatal bacterial infection (caused by Mycobacterium tuberculosis) that primarily attacks the lungs called?
Tuberculosis.
What is the fourth most use of the Respiratory system?
Voice production
What part of the Respiratory system exchanges oxygen and carbon dioxide?
The alveoli.
What is the fifth step in respiration?
Internal Respiration.
How does mucus interact with the lungs?
Mucus traps and destroys bad particles in the lungs.
What are infections that inflame the air sacs in one or both lungs (caused by bacteria, viruses, or fungi), leading to cough, fever, and difficulty breathing called?
Acute Lower Respiratory Tract Infections.
What is the fifth most common use of the Respiratory system?
Sense of smell.
What is the part of the Respiratory system that acts as the main muscle of respiration, driving inhalation and exhalation while separating the chest cavity from the abdomen
The diaphragm.
What is the fifth and final step in respiration?
Cellular Respiration.
How does the digestive system and lungs interact?
The throat acts as a shared passageway for both air and food. A flap of tissue called the epiglottis covers the voice box and trachea during swallowing to prevent food and liquid from entering the windpipe
What is a progressive group of lung conditions—including emphysema and chronic bronchitis—that blocks airflow and makes breathing increasingly difficult, most often caused by smoking called?
Chronic Obstructive Pulmonary Disease (COPD)?
