Blood And Swimbladder Flashcards
what does the blood do
supply tissues with nutrients
remove waste
provide tissues cells and organs with environment they need - osmotic environment
oxygen transporter pigment
haemoglobin
pushes oxygen saturation curve to the right
the bohr shift
which enzyme catalyses the reaction between h20 and c02
carbonic anhydrase
why do terrestrial animals have to cope with higher levels of c02 - acidic
Not constantly washed with water like gills
how do amphibians cope with developmental environments using blood
haemoglobin alters their properties
tadpoles to adults is accompanied by reduced affinity for o2
in amniotes chicks experience low levels of 02 and high co2 how do they survive
sphere lowest SA TO volume ratio- little gas exchange
haemoglobin increase affinity for oxygen during incubation and partial pressure for 02 decreases
root effect
over all decline in amount of oxygen carries by haemoglobin - reduction in 02 binding
in the swim bladder what prevent 02 from diffusing out
guanine crystals
rete
group of blood vessels
Swimbladder connected to esophagus
physosome
Swimbladder connected to gas gland
physocist
how does gas gland encourage release of 02 in rete mirable
release lactic acid forcing haemoglobin to release 02 in close vicinity. capillary loop prevent gas escaping
