Distinguish between:

Circulation
Distinguish between:
ARTERIES
and
VEINS
Pulmonary Artery – Takes
deoxygenated blood from _______ to
lungs (from right ventricle to lungs)
Purkinje Fibers – Conducting fibers in
the ventricles that takes action
potential and distributes it through
ventricular muscle mass for
contraction.
Vena Cava ->
RIGHT ATRIUM -> Atrioventricular
Valve -> RIGHT VENTRICLE ->
Pulmonary Valve -> PULMONARY
ARTERY -> Lungs -> PULMONARY
VEIN -> Left Atrium ->
Atrioventricular Valve -> LEFT
VENTRICLE -> Aortic Valve ->
AORTA
Single Circulation – Blood is pumped
to _________ and then to ________
and then returns to heart in one circuit.
Ex. __________
Double Circulation – Blood is
pumped to gills/lungs, back to
________, and then to body (two
circuits – pulmonary and systemic).
Ex. __________
Open Circulatory System – Fluid
leaves vessels and is squeezed
through intercellular spaces. A heart
may help distribute the fluid, but the
fluid leaves the vessel. Ex.:
Arthropods and Mollusks.
Systolic Blood Pressure – Pressure
of blood during ____________ of the
ventricles.
Fibrin – Active form of
_____________, an enzyme important
in clot formation. In clot formation,
exposed collagen from the wound
binds _____________ that signal
more platelets to bind and begin a
cascade of events that involve clotting
factors and activation of enzymes.
Erythrocyte – Red Blood Cell
(contains _____________ which
carries oxygen).
Atherosclerosis – Clogging of the
_____________ with a tough
substance called __________. _____
- ______________ lipoproteins
promote this disease, while _______ ______________ lipoproteins deter it.
Thrombin – Active form of
prothrombin. Clotting factors cause
prothrombin to activate into thrombin.
Thrombin then causes ____________
to polymerize and form threads of
fibrin to clot blood.
Platelets – Cell fragment formed in
bone marrow with membrane (no
nucleus) that is important in
___________. They release clotting
factors.
Arteries – Muscular blood vessel that
carries blood ____________ the heart.
Amphibian Circulation – _________
chambered heart with partially
separated ventricle.
Reptile Circulation- Ventricles are
partially divided by a septum. Reptiles
also have two _________ and can
redirect blood to bypass pulmonary
circuit. Crocodilians and alligators
have completely separated ventricles.
Sinoatrial Node – Pacemaker cells of
Pulmonary Vein – Takes oxygenated
blood from __________ to heart (to
left atrium)
Veins – Blood vessels that return
blood to heart. They contain
_________ to prevent backflow of
blood.
Diastolic Blood Pressure – Pressure
of the blood during __________ of the
ventricles.
Closed Circulatory System – Blood
stays in vessels separate from tissue
fluid. Ex: Vertebrates and Annelids
Systemic Circuit – Part of circulation
that serves body (everything except
for gills or lungs).
Pulmonary Circuit – Part of
circulation that serves _______ or
gills.
mammalian heart. These cardiac cells
initiate an action potential that stimulates
_______ contraction. Acetylcholine causes
slower heart beat while norephinephrine
causes increased heart beat.
Atrioventricular Node – Cardiac
muscle cells in junction between atria and
ventricles that generates action potential
after receiving from _________________.
