Why is exercise good for the respiratory system? - correct answer ✅When we exercise, our brain senses the high levels of CO2 in our blood. This triggers an increase in our rate of breathing, which works and strengthens the diaphragm (as well as heart and many other muscles). Thus our cardiovascular capacity can be improved through exercise. Describe the "vessel-pathway" that a red blood cell would take as it leaves the heart through the circulatory system. - correct answer ✅Aorta, arteries, arterioles, capillaries, venules, veins, vena cava, heart What is the main function of the trachea - correct answer ✅To deliver air to the lungs. Ciliated cells and mucus line the trachea and filter/trap debris that may have escaped the filter in the nasal passage What is the functional unit ( site of gas exchange) of the lung? - correct answer ✅alveoli
Explain the difference between the cardiovascular system and the respiratory system - correct answer ✅The cardiovascular system is the heart with its veins and arteries designed to circulate blood. The respiratory system is mainly the lungs designed to exchange CO2 for O How do the cardiovascular system and the respiratory system work together - correct answer ✅The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to disperse to the body. What are the two functions of the respiratory system? - correct answer ✅To bring in oxygen and remove carbon dioxide List several common illnesses that affect the respiratory system. - correct answer ✅Bronchitis, emphysema Why is it dangerous to hold your breath for too long? - correct answer ✅holding your breath stops oxygen from getting to your brain cells
CO2 (carbon dioxide) is a gas that is toxic to the human body in large quantities. Which organ system has the function of removing CO2 from the human body? - correct answer ✅Respiratory System In the Andes (a tall mountain range in South America) people live at elevations about 10,000 ft above sea level. At these high elevations there is less oxygen in the atmosphere. What are some characteristics that would help these people survive in this environment? - correct answer ✅Larger lungs List several activities that can negatively affect your respiratory system. - correct answer ✅Smoking, and not enough exercise List several things that a person would NOT be able to do if air does not pass through the larynx. - correct answer ✅talk, sing What would happen if your diaphragm muscle stopped working? - correct answer ✅You would not be able to inhale or exhale Which structure is the site of gas exchange, where O2 enters the blood and CO and H2O leave the blood? - correct answer ✅Capillaries, Alveoli
What are the functions of the nose and what structures allows for this - correct answer ✅Primarily the nose functions as a passageway for air to the trachea. The special feature of the nose is its tiny hairs and mucus which together filter the air removing debris. Also the blood vessels contribute to the warming of the air as it passes through the nose. What is another name for the trachea - correct answer ✅windpipe What is the relationship between the bronchi and the bronchioles? - correct answer ✅The bronchi are the two large branches of the trachea that carry air into the right and left lung from the trachea. Bronchioles are smaller branches of the bronchi that branch out like twigs of an upside down tree. These eventually lead into even smaller branches of the respiratory tract, and then move air into tiny sacs called alveoli.
the main function of the lungs - correct answer ✅The main function of the lungs is the gas exchange of carbon dioxide and oxygen. What are alveoli and how do they operate? - correct answer ✅Alveoli are the tiny sacs at the end of the bronchioles that look like clusters of grapes. The exchange of gases between the atmosphere and the blood occurs at the alveoli because both the walls of the alveoli and the walls of the capillary net surround the alveoli are only 1 cell thick allowing for O2 and CO2 to pass through them. The capillaries and alveoli work together to exchange gases. Draw a diagram depicting the flow of gases between the two. - correct answer ✅ What is the diaphragm - correct answer ✅The diaphragm is a sheet of smooth muscle beneath the lungs separating the organs of the chest cavity from those of the abdominal cavity that helps move air in and out of the body.
