The circulatory system pumps blood through the body to transport oxygen, food, water, and waste; it interacts with other systems like the skeletal and respiratory systems; and diseases can occur if it fails to properly maintain homeostasis, transport oxygen, and keep the blood vessels flexible, such as with a heart attack, stroke, or heart failure.

2. Functions
•
•
•
•
Pumps blood through the body.
Helps muscles move.
It transports food, water, and oxygen.
It also does elimination: carries out waste out
of blood

3. Major Organs
• Heart
• Veins

4. Interactions with other systems
• Skeletal System: Bones produce new cells
through bone marrow
• Respiratory System: It transports oxygen
through the blood

5. Role In maintaining Homeostasis
• The circulatory system transports oxygen to
where it is needed to keep the body healthy

6. Health and diseases
• Diseases: Heart attack, stroke, heart failure.
• Health: Blood vessels must be flexible so the
volume of blood flowing through them can
change.

7. Frequently asked questions
• How are white blood cells made?
• What is the heart for?
