CARDIOVASCULAR SYSTEM
The Heart
HEART (THE PUMP)
1 organ2 functions, 2 sides, 2 pumps
1) Pumps venous blood to the lungs
2) Pumps arterial blood to the cells
HEART STRUCTURE

CARDIOVASCULAR SYSTEM
CARDIOVASCULAR SYSTEM
Blood is circulated by the heart and blood vessels.
In one day, blood will be circulated 1 400 times!

DIAGRAMS
Vessels carrying O2 rich blood are RED
Vessels carrying CO2 rich blood are BLUE
BLOOD VESSELS
Different types, based on size and where they are going
BLOOD VESSELS
Arteries and ArteriolsSmall blood vessels carrying arterial (O2 rich) blood away from the heart to give O2 to the cells.
*except pulmonary artery
BLOOD VESSELS
Arteries and ArteriolsSmall blood vessels carrying
arterial (O2 rich) blood away from the heart to give O2 to the cells.
Larger arteries subdivide into smaller arterioles.
Has a lot of power because blood just left the heart.
BLOOD VESSELS
Arteries and ArteriolsThick walls to resist high pressure
BLOOD VESSELS
CapillariesThinnest blood vesselsAllow diffusion through a
semi-permeable membrane
BLOOD VESSELS
CapillariesBlood cells travel through in single file
Walls are a single layer of cells
Diffusion of gases
and nutrients
BLOOD VESSELS
Veins and VenulesSmall blood vessels that
carry blood back to the heart.
(CO2 rich except pulmonary vein)
Many smaller venules lead to larger veins
BLOOD VESSELS
Veins and VenulesVeins have valves to keep
blood from flowing downwardBlood has lost power from the heart
Blood is fighting gravity
BLOOD VESSELS
Veins and Venules Veins have valves to keep blood from flowing
downward Blood has lost power from the heart Blood is fighting gravity
Valves open and close, creating suction.
