Circulatory pathways in vertebrates
single-loop
double-loop
single
loop
is common in fishes, heart has a single
atrium
and a single
ventricle.
double
loop
has a
systemic
and
pulmonary
circuits.
heart is
coned-shape
muscular organ about the
size
of a fist.
heart
is located behind the
sternum
and tilted to the
left.
pathway of the
blood
from the body through the human
heart
is controlled by the different valves.
pulmonary
circuit collects
oxygen-poor
blood from all parts of he body to the lungs.
systemic
circuit carries
oxygen-rich
blood from the
lungs
throughout the body.
plasma
of the blood is about 55% of the whole count of the blood in the human body. it contains proteins involved in
buffering
the blood.
red blood cells contain
hemoglobin
which makes it
red
in color
granulocytes
consists of 3 phils
neutrophils
eosinophils
basophils
agranulocytes
- the monocytes are the largest know
leukocytes
which are large phagocytic macrophages.
lymphocytes
have a distinct role in adaptive immunity because of
T
-cells and B-cells
platelets
are known for its important function in blood clotting.
capillary exchange 3 phases
filtration
no net movement
reabsorption
circulatory system
is responsible for the movement of
fluids
between various parts of the body.
blood
is present in a
closed
system
