SYSTEM

“Putting it all together”
• We have talked about the 5 main body systems.
1. 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
