Lesson 2

2. The Circulatory System
Blood vessels carry blood to every part of your body.
Blood moves oxygen and nutrients to cells and carries carbon dioxide and other wastes away from the cells.

3. The Heart Organ made of cardiac muscle tissue.
Located behind breastbone and between lungs.
Has FOUR compartments
called chambers.
Atria
The two UPPER chambers
are called right and left atriums
Ventricles
The two lower chambers

6. Coronary Circulation
Coronary circulation- the flow of blood to the tissues of the heart.
Supplies heart with oxygen and nutrients
When these are blocked it results in a heart attack.

7. Pulmonary Circulation
The flow of blood through heart to lungs and back to heart.
Moves between heart and lungs
Drops off CO2 in the lungs and picks up oxygen to take back to the heart.

8. Systemic Circulation
Oxygen-rich blood moves to all of your organs and body tissues, except the heart and lungs, by systemic circulation.
Largest of the three sections of
Circulatory system.
Nutrients and oxygen- delivered
From heart to arteries.
Delivered to body cells and
Exchanged for CO2 and wastes.
Blood returns to your heart.

9. Path that Blood Takes
1. Blood enters right atrium in veins from body tissues
2. Right atrium contracts and blood enters right ventricle.
3. Right ventricle contracts.
4. Blood leaves right ventricle in pulmonary arteries.
5. Blood in pulmonary arteries exchanges CO2 for oxygen.
6. Oxygen-rich blood returns to left atrium.
7. Left atrium contracts and blood enters left ventricle.
8. Left ventricle contracts.
9. Blood leaves heart in arteries to body tissues.

10. Blood Vessels Arteries Veins Capillaries
Vessels that move blood away from the heart
Veins
Vessels that move blood toward the heart
Capillaries
Tiny blood vessels that connect arteries and veins

11. Blood Pressure
A force exerted on the walls of blood vessels by blood.

12. Section 2- Blood Functions of Blood
Carries oxygen from your lungs to all your body cells.
Carries waste products
from your cells to your
kidneys to be removed
Transports nutrients
and other substances to
your body cells.
Fight infections and
help heal wounds.

13. Hemoglobin BLOOD TYPES
Carries oxygen and CO2. gives blood its red color
BLOOD TYPES
A, B, AB, O
You CANNOT change your blood type.

14. Diseases of Blood
Anemia is a blood disorder of the red blood cells in which tissues can’t get enough oxygen.
Loss of large amounts of blood
Diet lacking iron or certain vitamins
The production of increased numbers of immature white blood cells is a disease called leukemia.
Medicines, blood transfusions, and bone marrow transplants are treatments.

15. Lymphatic System Lymph
The water and dissolved substances remaining between cells and diffused into lymphatic capillaries.
Lymph is made up of white blood cells, water, and dissolved substances.
Your lymphatic system collects fluid from body tissue spaces.
Uses skeletal and smooth muslces for movement.

16. Lymphatic Organs
Lymph nodes, tonsils, thymus, and spleen

Thymus
Spleen
