Flashcards in Respitory Deck (18):
a gas in the air (and water) that animals need to breathe in; made up of particles with two oxygen atoms. Plants produce oxygen as part of photosynthesis.
the chemical reaction involving oxygen that moves the energy in glucose into the compound ATP. The body is able to use the energy contained in ATP.
a simple carbohydrate and the simplest form of sugar
a gas in the air produced by respiration and used by plants as part of photosynthesis. The burning of fossil fuels releases carbon dioxide.
the body system involving the lungs and associated structures, which take in air and supply the blood with oxygen to deliver to the body’s cells so they can carry out their essential functions; it also performs gas exchange to remove the waste gas carbon dioxide
narrow tube from the mouth to the lungs through which air moves
the organ for breathing air. Gas exchange occurs in the lungs.
the narrow tubes through which air passes from the trachea to the smaller bronchioles and alveoli in the respiratory system. Singular = bronchus.
small branching tubes in the lungs leading from the two larger bronchi to the alveoli
tiny air sacs in the lungs at the ends of the narrowest tubes. Oxygen moves from alveoli into the surrounding blood vessels, in exchange for carbon dioxide.
the vessel through which oxygenated blood travels from your lungs to the heart
a large artery through which oxygenated blood is pumped at high pressure from the left ventricle of the heart to the body
vessels that transport oxygenated blood from the arteries to the capillaries
the vessel through which deoxygenated blood, carrying wastes from respiration, travels from the heart to the lungs
flexible, dome-shaped, muscular layer separating the chest and the abdomen. It is involved in breathing.
the largest volume of air that can be breathed in or out at one time
