How many times does the ventricle pump blood to gills in the fish during one circulation?
1
2
3
4
What type of blood does the fish pump in its CS?
oxygenated blood
deoxygenated blood
Why is the fish able to only have 1 atrium and 1 ventricle?
Gas exchange is efficient and aquatic
have gills
operculum pumps water out fast
Where does the mixing of oxygenated and deoxygenated blood occur?
atrium
ventricle
lung
systemic capillaries
Who has an open circulatory system?
Mollusca
Arthropoda
Fish
amphibians
Choose all that apply to a reptile's (excluding crocadiles) circulatory system.
1 ventricle
septum
2 atria
open circulatory system
Why is it important that a septum separate deoxygenated and oxygenated blood in reptiles (not crocadiles)?
ectotherm/terrestrial and do not have cutaneous respiration like the frogs
Endotherm/terrestrial and do not have cutaneous respiration like the frogs
do cutaneous respiration
What describes the circulatory system of chordata/cephalopoda? Choose all that apply.
2 atria
2 ventricles
closed circulatory system
completely removes mixing of blood; most efficient
Why do chordates need a circulatory system that completely removes mixing of deoxygenated and oxygenated blood?
aquatic
endotherms, high metabolism
ectotherms, energy changes with the temperature of the environment
What part of this system pumps the oxygen-poor blood through the pulmonary valve to the lungs?
Right ventricle
Left ventricle
Right atrium
Left atrium
What part of this circulatory system receives oxygen-rich blood from the lungs and pumps it to the left ventricle?
left atrium
right atrium
left ventricle
right ventricle
What part of the circulatory system pumps the oxygen-rich blood through the aortic valve out to the rest of the body?
right atrium
left ventricle
right ventricle
left atrium
