Respiration And Gaseous Exchange Flashcards
What is respiration
The aerobic or anaerobic breakdown of glucose in order to release energy
What is aerobic respiration
Respiration occurring in the presence of oxygen
What is anaerobic respiration
Respiration occurring in the absence of oxygen
What is breathing/ventilation
Mechanical process of inhaling and exhaling
List three processes of aerobic respiration
Glycolysis. krebs cycle .oxidative phosphorylation
What is gaseous exchange
Exchange of gases between the air and blood in the lungs
What are the six requirements for effective respiration
It must be well-ventilated.
It must be protected.
It must be large.
It must be moist.
It must be vascular.
It must be thin and permeable.
List in order the nine parts of the respiratory system
Nasal cavity.
Pharynx .
Larynx.
Trachea.
Bronchi.
Bronchioles.
Alveoli
Lungs.
Diaphragm.
What is another name for the chest
Thoracic cavity
What is an epiglottis
A cartilage structure on top of the larynx which closes when food is followed preventing food from entering the trachea only allowing air to pass over it
Which type of cell lines the alveolus wall
Squamous epithelium
Which blood vessel carries blood with high concentration of carbon dioxide through the alveoli
Pulmonary artery
Which blood vessel transports oxygenated blood away from the alveoli
The pulmonary vein
Which type of cell makes up the capillary wall which takes part in gaseous exchange
endothelium cells
In which gases exchange structure are the cilia found
The bronchus
Where does aerobic respiration take place
Aerobic respiration takes place in the cytoplasm in mitochondria
What happens to the thoracic cavity ,the intercostal muscles, the diaphragm when someone inhales
During inhalation and thoracic cavity expands as it is filled with air the intercostal muscles contract and the diaphragm contracts
What happens to be the thoracic cavity, intercostal muscles, rib cage and diaphragm during exhalation
Thoracic cavity reduces ,intercostal muscles relax, the rib cage relaxes and diaphragm relaxes
What is the name of the fluid that acts as a lubricant to prevent friction during inhalation and exhalation in the lungs
Pleural fluid
