Pathway
of blood through the heart
1. Left side of heart receives
deoxygenated
blood
2. Right side of heart pumps
oxygenated
blood
3.
Oxygenated
blood enters through pulmonary vein and exits through
aorta
4.
Deoxygenated
blood enters through pulmonary artery and exits through
lungs

Pathway
of blood to working muscles
1. Blood exits aorta
2. Enters artery
3. Travels to part of body
4. Enters arteriole
5. Enters capillary
6. Diffusion of oxygen into muscles
View source
Pathway
of blood from muscles to lungs
1. Blood becomes
deoxygenated
2. Enters
venule
3. Enters
vein
4. Travels back to
heart
5. Enters
pulmonary vein
6. Exits heart through
pulmonary artery
7. Gets
reoxygenated
in lungs

Blood
Made up of 4 different components: red blood cells,
white
blood cells, plasma,
platelets

Platelets
Help clot blood, create a
mesh
to prevent blood from
leaking
out
View source
