respiratory system Flashcards
the structure in the respiratory system that is the origin of vocalisation. found at the top of the trachea
larynx
the structures in the respiratory system that are tiny air pockets with rich blood
alveoli
the structure in the respiratory system that is the main respiratory organ in vertebrates. site for gas exchange
lungs
the area of the respiratory system at the back of the throat with the opening to the windpipe
pharynx
in the respiratory system what is the tube that connects to the lungs, held open with cartilage rings and have cilla
trachea
the part of the respiratory system where the trachea separated into two tubes, one to each lung
bronchus
a structure of the avian respiratory system which are equivalent to nostrils
nares
the structure of the avian respiratory system which is the origin of vocalisation (instead of larynx)
syrinx
the structure of the avian respiratory system that is connected to lungs and some to hollow bones. they decrease the weight of the bird and improve air flow to the lungs
air sacs
birds do not have a ______. pressure changes move air through the air sacs and lungs
diaphragm
the structure of the avian respiratory system that runs through the lung between the bronchi. they replace the alveoli for gas exchange
air capillaries
the protein found in RBC, contain 4 iron ions, carried 4 oxygen molecules, transport oxygen around the blood
haemoglobin
found in muscle cells, is an oxygen and iron protein that releases oxygen to muscle cells, carries 1 oxygen molecule, acts as oxygen store
myoglobin
______ __________ has a higher affinity for oxygen compared to mothers haemoglobin. it is more efficient at extracting oxygen from maternal circulation
foetal haemoglobin
the type of respiration that involves oxygen combining with glucose to produce energy
aerobic
