Heading down there in August too. I'm no expert, but having vacationed in the OBX the last 5 years, I know August is the early portion of hurricane season. Most season's typically peak in September, but August has its fair share (Katrina). Jamaica is just as vulnerable as any other island in that neighborhood.
Gas exchange in the lungs takes place in the tiny air sacs called alveoli in the lungs. The process of inhalation must inflate the alveoli, but it can only do so because of the presence of a surfactant fluid that coats the alveoli and lowers the surface tension of their walls.as exchange in the lungs takes place in the tiny air sacs called alveoli in the lungs.

Words to Know. Alveoli: Tiny air-filled sacs in the lungs where the exchange of oxygen and carbon dioxide occurs between the lungs and the bloodstream. Bronchi: Two main branches of the trachea leading into the lungs.Bronchial tree: Branching, air-conducting subdivisions of the bronchi in the lungs.he exchange of these gases occurs across cell membranes both in the lungs (external respiration) and in the body tissues (internal respiration). Breathing, or pulmonary ventilation, describes the process of inhaling and exhaling air. The human respiratory system consists of the respiratory tract and the lungs.
