Nervous System
-structures that control the actions and reactions of the body.
Circulatory System
-consists of the heart, blood vessels, and blood.
Digestive System
-breaks down food that can be used as energy for cells.
Respiratory System
-system that helps us breathe in and out.
Skeletal/Muscular Systems
-works together to allow us to do multiple activities.
So…...let’s look at how these systems interact with each other

How the Nervous System interacts with other body systems.
•
Nervous/Skeletal
• Bones provide
Calcium
that is essential for the proper functioning of the nervous system.
• Skull protects the brain from injury. • Vertebrae protect the
spinal cord
. • The brain regulates the position of bones by controlling muscles.
How the Nervous System interacts with other body systems.
•
Nervous/Circulatory
• The brain regulates
heart rate
and blood pressure.
•
Nervous/Muscular
• The brain controls movement of the skeletal muscle. • The
nervous system
regulates the speed at which food moves through the digestive tract.
How the Nervous System interacts with other body systems.
•
Nervous/Digestive & Excretory
• The brain controls drinking and feeding behavior. • It also controls
muscles
for eating and elimination.
• The bladder sends sensory information to the brain. The brain controls urination.
•
Nervous/Respiratory
• The
brain
regulates respiratory rate.
How the Circulatory System interacts with other body systems.
•
Circulatory/Digestive
•
Blood
carries broken down nutrients through the blood stream to the body for energy • Carries nutrients to cells and
waste
from cells.
How the Circulatory System interacts with other body systems.
•
Circulatory/Respiratory
• Blood carries oxygen from your lungs to your body.
• The circulatory system also picks up waste products from cells.
• Ex. When cells use glucose (sugar), they produce carbon dioxide as a waste product. The carbon dioxide passes from the cells into the blood. The circulatory system then carries the carbon dioxide to the lungs, where it is exhaled.
How the Circulatory System interacts with other body systems.
•
Circulatory/Skeletal
• Bones have blood vessels and marrow, which produce red blood cells.
•
Red
blood cells pick up oxygen and deliver it to the rest of the body.
•
Circulatory/Muscular
• Smooth muscle helps move
materials
throughout the body.
• Found in arteries and veins to control blood flow through the blood vessel.
How the Digestive System interacts with other body systems.
•
Digestive/Muscular
•
Waves
of muscle contractions move food into the stomach.
• Ex: muscle moves food along the same way you move toothpaste from the bottom of the tube with your thumbs
How the Respiratory System interacts with other body systems.
•
Respiratory/Muscular
•
Muscles
in our body enable us to breath.
How the Respiratory System interacts with other body systems.
•
Respiratory/Circulatory
• Alveoli allows for
oxygen
to move into the blood stream • Also receives
carbon dioxide
to pass back through the lungs and out the body.

How the Skeletal/Muscular systems interact with other body systems.
•
Muscular/Circulatory
• Pumping
blood
though your body •
Muscular/Respiratory
• Enabling you to breathe •
Muscular/Skeletal
• Hold you upright • Allow you to move.

Connection to Plants
• Both plants and animals have a circulatory system to transport water, oxygen and nutrients.
• Plants make their own food for energy; animals eat food for energy • Primary energy source is the sun • Both use water and oxygen for nutrients • Humans have skeletal system for support; plants have a stem and roots for support • Both plants and animals digest food, excrete wastes and reproduce
