Respiratory System (Standard 7.L.1.4)
Terms in this set (13)
the throat; both air and food pass through it before continuing to either the trachea for air or esophagus for food.
a flap of tissue that seals off the trachea when swallowing food to prevent food from entering the lungs
the voice box; located at the top of the trachea, under the epiglottis.
also called the windpipe. This tube allows air to pass from the larynx to where it divides into the left and right bronchi. It is made of rings of cartilage that provide protection from collapse.
bronchi (plural)/bronchus (singular)
these passageways direct air into either the left lung or the right lung from the trachea
essential organs of respiration whose main function is to exchange carbon dioxide and water vapor for oxygen in the bloodstream.
each bronchus divides and subdivides into smaller and smaller branches like the branches of a tree
alveoli (plural)/alveolus (singular)
tiny air sacs that resemble bunches of grapes that link the respiratory system with the circulatory system. Gas exchange happens here.
movement of air into and out of the lungs
after air enters an alveolus, oxygen passes through the wall of the alveolus and then through the capillary wall into the blood. Carbon dioxide and water vapor pass from the blood into the alveoli.
the biochemical process in which oxygen and glucose (sugar) undergo a complex series of chemical reactions inside mitochondria in our cells to produce energy
where gas exchange takes place
Function of the respiratory system:
1. to bring oxygen into the body so it can be used by the cells to make energy 2. to remove carbon dioxide waste from the body through exhale
