The circulatory system transports blood throughout the body using the heart, blood vessels, and blood. The heart pumps blood through arteries, veins, and capillaries, which carry oxygen, nutrients, waste, and carbon dioxide between tissues and organs. The circulatory system includes pulmonary circulation from the heart to the lungs, coronary circulation through the heart tissue itself, and systemic circulation from the heart to the rest of the body except the lungs.

4. Circulatory System
• Function and Parts

5. • The circulatory system is the life
support structure that nourishes
your cells with nutrients from the
food you eat and oxygen from the
air you breathe.
• Another name for the circulatory
system is the cardiovascular
system.

6. Function
• Transport materials needed by
cells
–Oxygen
–Glucose
• Remove waste materials from cells
–Carbon dioxide
–urea

7. 1. Heart – pumps the blood throughout the body
2. Blood vessel – carries the blood throughout the body
Arteries - carry oxygenated blood away from the heart
to the cells,
tissues and organs of the body
Veins - carry deoxygenated blood to the heart
Capillaries - the smallest blood vessels in the body,
connecting the
smallest arteries to the smallest veins
- the actual site where gases and nutrients are
exchanged
3. Blood – carries the materials throughout the body

8. Parts of the Circulatory System
• The Heart - is divided into FOUR Chambers

9. Two types of Arteries
• Arteries start with A
takes blood away !!
• Aorta – Largest blood
vessel in the heart
• Pulmonary Artery –
Carries blood containing
carbon dioxide from
your heart to your lungs

10. Three Types of Veins
• Veins start with V
brings blood back to
me
– 1. Inferior Vena Cava –
Where the blood enters
the heart from the body.
– 2. Superior Vena Cava –
Where the blood enters
the heart from the body.
– 3. Pulmonary Vein –
Carries blood-containing
oxygen from your lungs to
your heart.

11. Three Kinds of Blood Vessels
• Arteries – Carries blood away from the heart
• Veins – Carries blood back to the heart
• Capillaries – Delivers low-oxygen blood to
veins (Smallest)

12. Parts of the Blood
• Red Blood Cells – Made
in bone marrow; carries
oxygen, food, and rids
body of CO2 and Waste
• White Blood Cells – Help
fight disease and
infection by destroying
bacteria and germs that
enter the body. Made in
the lymph nodes

13. Parts of the Blood
• Platelets – Help blood
to clot, to prevent
excess bleeding.
• Plasma – Water
portion of the blood;
55% of blood is
plasma

14. TYPES OF CIRCULATION
• PULMONARY CIRCULATION
• Movement of blood from the heart,
to the lungs, and back to the heart

15. TYPES OF CIRCULATION
• CORONARY CIRCULATION
• Movement of blood through the
tissues of the heart

16. TYPES OF CIRCULATION
• SYSTEMIC CIRCULATION
• Movement of blood from the heart
to the rest of the body, excluding the
lungs

17. ACTIVITY 4
• LET’S ORGANIZE
• Objectives:
• Identify the components of the circulatory
system
• Explain the different types of circulation
