Posted under IC22 Life Insurance Underwriting

Answer: (d).Respiratory system Explanation:The Respiratory system is responsible for the exchange of gases between the circulatory system and the outside world. The respiratory system includes the upper and lower airways (the nasal cavity, pharynx, larynx, trachea, primary bronchi, and bronchial tree) that transport air to and from the lungs. The diaphragm is a sheet of muscle that separates the thoracic cavity (where the lungs are located) from the abdominal cavity, and helps to regulate breathing. The larynx is part of the upper airway and contains the vocal cords. The respiratory system works together to allow for the exchange of oxygen and carbon dioxide in the body.
