0707.1.2 and 0707.1.3
Can I explain the basic functions of a major organ system?
How do different organ systems enable a complex multicellular
organism to survive?
Cardiovascular Demonstration
Stick the toothpick in your marshmallow with the sharp side up.
Lay your arm on the desk with your palm facing up.
Set the marshmallow on your wrist and sit as still as possible.
What observations can you make?

The Cardiovascular System
Your heart, blood, and blood vessels make up your cardiovascular system.
Your heart creates pressure when it beats, moving blood throughout the body.
The cardiovascular system helps maintain homeostasis (stable internal environment) by:
Carrying blood and nutrients to your cells and removing wastes from your cells.
Carrying chemical signals called hormones throughout the body.
The Heart
The heart is an organ made mostly of
cardiac muscle tissue.
The heart is about the size of your fist and
is almost in the center of your chest cavity.
The heart pumps blood through blood
vessels. The vessels carrying oxygen-rich
blood are shown in red. The vessels
carrying oxygen-poor blood are shown in
blue.
Blood
Blood is a connective tissue made up of
plasma, red blood cells, platelets, and white
blood cells.
Blood travels throughout your body carrying
oxygen and nutrients in hollow tubes called
blood vessels.
• Three types of
blood vessels:
• Arteries- carries
blood away
from the heart
• Capillariesallows
exchanges
between body
cells and blood
• Veins- carries
blood back to
the heart

HBS Chart
Function: The heart pumps blood through all of your
vessels. Carries nutrients to cells.
Major Organs: The heart, arteries, veins
How it works with other systems: Carries nutrients
from the digestive system to the cells. Carries oxygen
from the respiratory system to the cells and delivers
carbon dioxide to the lungs.
