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!

CARDIOVASCULAR SYSTEM

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.
