Skeletal/Muscular System
Our skeleton is composed of what?
Bones (& joints)
Most digestion happens here where acid dissolves food
Stomach
Main organ that helps us breathe
Lungs
Main organ that controls the body
Brain
Main organ that pumps blood through the body
Heart
Movement
What is the gas we inhale?
What is the gas we exhale?
Oxygen
Carbon Dioxide
Spinal Cord
These are what transport different things through the blood stream (we referred to them as UPS drivers
Red blood cells
Other than movement, what else does the muscular system create in the body?
Heat
This is where nutrients are pulled from food to be sent to cells in the body
Small intestines
How does air travel from the nose/mouth to the lungs? This is also called the windpipe
Trachea
Bundles of fibers found throughout the body that sends electrical impulses to and from the brain to the other body structures.
Nerves
What are two different types of blood vessels we have?
Veins
Arteries
Capillaires
List the 4 jobs of the skeletal system
Protect organs
Provide movement
Produce red blood cells
Provide structure
Explain the two ways digestion begins in the mouth?
Teeth grind food up
Saliva helps soften food
Where do the lungs put oxygen after the take it in?
In the blood stream.
Explain the job of the Nervous System
What does it mean when we say blood circulates through our body
Blood moves continuously in a circle through our body as travels between our heart and different parts of our body
What are the 3 types of muscles in our body
Skeletal, Smooth, and Cardiac
Explain why the digestive system is important for our body
It breaks food apart to get the nutrients out that can be sent to our cells
Why is it important that our bodies take in oxygen?
Our cells need it for energy
Provide an example of how the Nervous system would work with the muscular systems
Something about the brain causing the body to move
List two different body systems that the circulatory systems work with and explain how they work together
Respiratory- oxygen is taken through the blood to cells & CO2 is taken the blood to be removed from the body
Digestive: Nutrients pulled from food is put in the blood to be sent to cells
