Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta

2. THE CARDIOVASCULAR
SYSTEM
1/The circulatory system sometimes called as cardiovascular system, consists
of the heart, blood vessels and blood.
a/It transports oxygen , hormones and nutrients to all the cells in the body.
b/It picks up waste products generated by metabolic processes and delivers
them to other organs for disposal.
2/The heart provides the muscle needed to pump blood throughout the
body.
3/The system circulates blood in two circuits:
a/Pulmonary circuit
b/Systemic circuit

3. THE CARDIOVASCULAR
SYSTEM.(Organs/Component and their functions)
1/Heart- Propels blood ; maintains blood pressure.
2/Blood Vessels- Distribute blood around the body.
a/Arteries- Carry blood from heart to capillaries.
b/Capillaries- Permit diffusion between blood and interstitial fluid.
c/Veins- Returns blood from capillaries to heart.
3/Blood- Transports oxygen from the lungs to the cells of the body.

4. CIRCULATION OF BLOOD THROUGH THE
HEART.
• Blood comes into the right atrium of the heart from the body, move
into the right ventricle and is pushed into the pulmonary arteries in
the lungs. After picking up oxygen, the blood travels back into the
heart through the pulmonary veins into the left atrium ,to the left
ventricle and out of the body’s tissues through the aorta.

5. PULMONARY CIRCULATION
Pulmonary circulation transports de-oxygenated blood from heart to
the lungs to be re-saturated with oxygen before being dispersed into
the systemic circulation.

6. SYSTEMIC CIRCULATION
Systemic Circulation returns oxygen rich blood and nutrients to the left
atrium and is pumped out all over the body.
It also picks carbon dioxide and other waste products.

8. CIRCULATORY SYSTEM WORKING WITH
OTHER BODY SYSTEMS
• When your blood circulates through your digestive system, it picks up
nutrients your body absorbed from your last meal.
• Your blood also carries oxygen inhaled by the lungs. Your circulatory system
delivers oxygen and nutrients to your heart and other cells of your body
then picks up any waste products created by these cells, including carbon
dioxide and delivers these waste products to the kidney and lungs for
disposal.
• The circulatory system carries hormones from the endocrine system, and
immune system’s white blood cells that fight off infection.
• The circulatory system provides your brain with constant supply of oxygen-
rich blood while your brain regulates your heart rate and blood pressure.
• Your circulatory system delivers oxygen rich blood to your bones.
Meanwhile, your bones are busy making new blood cells.
