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
