Respitory System Flashcards
Larynx
The voice box
Trachea
Tube that connects the pharynx and the lungs
Bronchi
Two divisions of breathing passageway that lead from the trachea to the lungs
Bronchioles
The smallest divisions of the breathing passageways that lead from the bronchi into the lungs
Alveoli
Small sachs where gas exchange in the lungs occurs
Cellular respiration
The conversion of glucose and oxygen into ATP and carbon dioxide,.. occurs in the mitochondria of eukaryotic cells
ATP
The energy molecule of cells, formed in the process of cellular respiration
Mucus
Slippery secretion that lines the breathing passageways, helps to trap pathogens that are inhaled
Cilia
Miniature, hairlike organelles that line the surface of cells of the breathing passageways
Diffusion
The movement of materials from a high area of concentration to a low area of concentration,.. How oxygen and carbon dioxide move in and out of the blood in the respiratory and circulatory systems
Gas exchange
The process of exchanging gas into and out of the cells with carbon dioxide moving in the opposite direction
Diaphragm
The Dome-shaped sheet of muscle and tendon that serves as the main muscle in respiration and plays a vital role in the breathing process
Inhalation
Breathing in
Exhalation
Breathing out
Asthma
Chronic (long-term) lung disease that inflames and narrows the airways
Bronchitis
An inflammation in the lining of your bronchial tubes, general caused by a bacterial infection of the bronchi
Emphysema
Gradually damages the air sacks (alveoli) in your lungs, making you progressively more short of breathe
Pneumonia
An inflammatory condition of the king affecting primarily the microscopic air sacks called alveoli, generally caused by a bacterial infection of the aveoli
COPD
Cronin obstructive pulmonary (pull-mun-ary) disease is a progressive disease that makes it hard to breath
Lung cancer
Cancer of the lungs
Pharynx
The throat, connects the mouth to the entrance of the trachea and esophagus
