CARDIOVASCULAR SYSTEM

The Heart

Heart (the pump)

1 organ

2 functions, 2 sides, 2 pumps 1) Pumps venous blood to the

lungs 2) Pumps arterial blood to the

cells

Heart Structure

4 Chambers

LEFT VENTRICLE

RIGHT VENTRICLE

RIGHT ATRIUM

LEFT ATRIUM

Blood Pathway

Blood enters the Left Atrium from the pulmonary veins

LEFT ATRIUM

Pulmonary Veins– Blood from lungs

Blood Pathway

Chambers open and close, pushing blood.

When the atrium contracts, blood is pushed to the ventricle.

Blood Pathway

The left ventricle is the largest chamber.

It pumps blood to the whole body when it contracts.

LEFT VENTRICLE

Aorta – blood to body

Blood Pathway

Once the blood has circulated through the body, it returns to the heart

From upper veins: superior vena cava

From lower veins: inferior vena cava

Superior Vena Cava

Inferior Vena Cava

Blood Pathway

Blood enters the RIGHT ATRIUM from these veins

Then it is pushed to the RIGHT VENTRICLE RIGHT

VENTRICLE

RIGHT ATRIUM

Blood Pathway

The Right ventricle contracts

Blood is pushed through the PULMONARY ARTERY towards the lungs, where it picks up O2

It then returns to the heart through the pulmonary vein

RIGHT VENTRICLE

RIGHT ATRIUM

Pulmonary Arteries

Systemic Circulation – through the body

Left Ventricle

Aorta (an artery)

Arteries

Arterioles

Capillaries (diffusion of gases, nutrients, waste collected)

Venules

Veins (Inferior or superior vena cava)

Right Atrium

Pulmonary Circulation – (lungs)

Right ventricle

Pulmonary Artery

Capillaries of the lungs (surround alveoli – diffusion of gases)

Pulmonary vein

Left Atrium
