The circulatory system transports oxygen, nutrients, antibodies, and removes waste through the heart, blood vessels, blood, lungs, and body cells. The heart pumps deoxygenated blood to the lungs and oxygenated blood to the body through a double circulation. The circulatory system consists of arteries, which carry blood away from the heart; veins, which carry blood toward the heart; and capillaries, which connect arteries and veins and allow for gas and nutrient exchange. Common cardiovascular diseases include coronary heart disease, stroke, and peripheral arterial disease.

1. THE CIRCULATORY SYSTEM

2. FUNCTIONS/ IMPORTANCES OF THE
CIRCULATORY SYSTEM:
• FUELS THE BODY (OXYGEN AND NUTRITION)
• REMOVES METABOLIC WASTE (CARBON DIOXIDE)
• FIGHT DISEASES (ANTIBODIES)

3. COMPONENTS OF THE CIRCULATORY
SYSTEM:
• HEART
• BLOOD VESSELS
• BLOOD
• LUNGS
• BODY CELLS

4. THE HEART
FUNCTIONS
• THE HEART CIRCULATES BLOOD
AROUND THE BODY ( MILLER, 2017).
• THE RIGHT SIDE PUMPS
DEOXYGENATED BLOOD (CONTAINS
CARBON DIOXIDE).
• THE LEFT SIDE PUMPS
OXYGENATED BLOOD (CONTAINS
OXYGEN).

5. BLOOD VESSELS
ARTERIES
• TRANSPORTS
DEOXYGENATED BLOOD
AWAY FROM THE HEART.
VEINS
• TRANSPORTS OXYGENATED
BLOOD INTO THE HEART.
CAPILLARIES
• SMALLEST BLOOD VESSELS
THAT CARRY BLOOD FROM
ARTERIES TO BODY CELLS
AND LATER TO THE VEINS.

6. THE DOUBLE CIRCULATION

7. DOUBLE CIRCULATION (EXPLAINED!!!!)
• LINK TO THE DOUBLE CIRCULATION TUTORIAL:

8. PULSE RATE
• IS THE NUMBER OF HEARTBEATS PER MINUTE (BPM).
• A HEALTHY ADULT HAS 60-100 BEATS PER MINUTE (BPM).
• DURING A STRENUOUS ACTIVITY, THE BPM IS EXPECTED TO RISE EVEN ABOVE
100 BEATS PER MINUTE.

9. CARDIOVASCULAR DISEASES
• CORONARY HEART DISEASE- OCCURS BY A BLOCKED BLOOD FLOW IN THE
ARTERIES, DUE TO FATTY DEPOSITS.
• STROKE- OCCURS WHEN THE BLOOD SUPPLY TO THE BRAIN IS CUT OFF. IT
CAN LEAD TO BRAIN DAMAGE AND DEATH.
• PERIPHERAL ARTERIAL DISEASE- OCCURS WHEN THE ARTERIES IN THE
LIMBS ARE BLOCKED, CAUSING PAIN IN THOSE LIMBS.
