Main Parts:
• Bones
• Cartilage
• Connective Tissue
38. Three types of muscles found in the
body:
•Cardiac – found in the
heart (involuntary muscle)

information from inside
and outside of the body

4. Nervous System
Main Parts
• Brain
• Nerves
• Spinal Cord

5. Circulatory System
Function
• Carries blood and
nutrients to the cells of
the body
• Carries waste away from
the cells, such as carbon
dioxide.
43. 11 Human Body Systems
5. Circulatory System
Main parts:
• Heart
• Blood
• Veins
• Arteries
44. What it helps you do…
•Arteries help carry oxygenated
blood away from the heart
•Veins carry un-oxygenated blood
toward the heart
•Capillaries are tiny blood vessels
that connect arteries and veins.
Gas exchange takes place here.
45. Interactions with other systems:
•Works with the respiratory system to help you
transport oxygen and carbon dioxide.
•Works with the excretory to help remove waste
from the body.
•Works with the digestive system to transport
nutrients.
•Works with the muscular system to help
circulate nutrients.

6. Endocrine System
Function:
• collection of glands that
produce hormones that
regulate metabolism, growth
and development, tissue
function, sexual function,
reproduction, sleep, and mood.
