Study Notes
Heart and Circulatory System
- Blood is pumped throughout the body by the heart, which is roughly the size of a fist.
- The heart pushes blood through the lungs where it picks up oxygen.
- Blood travels around the body through blood vessels.
- Arteries carry oxygenated blood to body organs.
- Blood vessels bring oxygen to all organs.
Blood's Function
- Blood carries oxygen to each organ.
- Waste products, like carbon dioxide, are removed from organs.
- Blood carries carbon dioxide back to the lungs to be exhaled.
- Veins carry deoxygenated blood back to the heart.
Blood Vessels
- Many blood vessels exist in the body, allowing travel from one end to the other.
- Traveling from New York to California and back is possible following blood vessels.
- Blood transports nutrients from digested food to needed organs.
Circulatory System
- The circulatory system provides a constant supply of oxygen and nutrients to the body.
- Blood circulates continuously, delivering oxygen and nutrients throughout the day and night.
- This constant circulation is essential for the smooth functioning of the body.
