Briefly explain why maintaining a healthy weight is important in cardiovascular system care.
Maintaining a healthy weight reduces the stress on the heart and blood vessels.
Explain how smoking damages the respiratory system and name two conditions that can develop when a person smokes.
The lungs need to remain elastic so they can effectively move oxygen into the body and carbon dioxide out of the body. By smoking, you are actually introducing carbon monoxide into the body, which is toxic. Tars and other chemicals will settle on the cilia of the lungs and cannot be removed; which further degrades the functionality of the respiratory system. Two conditions that develop when a person smokes are emphysema and bronchitis.
Describe the location and importance of cilia and mucus in the respiratory system.
Mucus and cilia help filter dust and dirt. Cilia are small, hair-like structures in the nasal passage and trachea. Mucus is also found in the nasal passage and the trachea.
Explain why cardiovascular diseases are the leading cause of death in men and women in the United States.
Generally, many cardiovascular diseases are related to lifestyle behaviors. Factors that contribute to the development of cardiovascular disease include lack of a balanced diet, lack of exercise, smoking, and the lack of regular doctor visits.
Describe the location and importance of cilia and mucus in the respiratory system.
Mucus coats the respiratory passages, including the nose, trachea, and bronchi, and traps dust, germs, and other particles. Tiny hairlike cilia lining these passages move the mucus toward the throat, where it can be coughed out or swallowed. Together, they help keep the lungs clear.
