(a) Respiration and Breathing
Respiration: A biochemical process in which energy is released from glucose.
Breathing: A physical process of inhaling oxygen and exhaling carbon dioxide.
(b) Respiration and Photosynthesis
Respiration: Breaks down glucose to release energy.
Photosynthesis: Produces glucose using sunlight and releases oxygen.
(c) Inhalation and Exhalation
Inhalation: The process of taking in oxygen-rich air into the lungs.
Exhalation: The process of expelling carbon dioxide-rich air from the lungs.
(d) Stomata and Lenticels
Stomata: Small openings on leaves for gas exchange.
Lenticels: Small openings on stems for gas exchange.
(e) Diffusion and Osmosis
Diffusion: Movement of molecules from high to low concentration.
Osmosis: Diffusion of water through a selectively permeable membrane.
(f) Smoker and Passive Smoker
Smoker: A person who actively smokes tobacco.
Passive Smoker: A person who inhales smoke from a smoker.
(g) Bronchitis and Pneumonia
Bronchitis: Inflammation of the bronchi due to infection or irritation.
Pneumonia: Infection that inflames air sacs in the lungs, causing fluid accumulation.
(h) Aerobic and Anaerobic Respiration
Aerobic Respiration: Uses oxygen to produce energy.
Anaerobic Respiration: Occurs without oxygen, producing less energy.
(i) Pharynx and Larynx
Pharynx: A passage for both food and air.
Larynx: The voice box involved in sound production.
(j) Glottis and Epiglottis
Glottis: The opening of the larynx.
Epiglottis: A flap that prevents food from entering the windpipe.
