Muscular and Skeletal
What are the main functions (jobs) of the skeletal system
1. Support and Shape
2. Movement
3. Protects vital organs
4. Creates blood cells
What is the main function of the respiratory system? What does it give to the body and what does it get rid of?
Breathing. Gives the body oxygen and gets rid of carbon dioxide (waste)
What is the main function (or job) of the cardiovascular system?
To send oxygen and nutrients to all parts of the body through the bloodstream. Also, it helps the body to get rid of waste (carbon dioxide)
What are the three main parts of the nervous system?
The brain, spinal cord, and nerves.
What is the main purpose of the digestive system?
To turn food into energy for the body
What is the primary function of the muscular system?
Movement and strength
What are the organs/parts of the respiratory system?
Nose/mouth, Trachea, Lungs, and the diaphragm
What are the three main parts of the cardiovascular system?
The heart, blood vessels (arteries, veins, capillaries), and blood
What organ is the control center (command center) for the body?
The Brain
What are the 5 main organs/parts of the digestive system?
Mouth, Esophagus, Stomach, Small Intestine, and Large Intestine.
What are the three main types of muscles found in the body?
Smooth Muscles - digestive system, respiratory system (involuntary)
Cardiac Muscles - heart muscles that help pump blood (involuntary)
Skeletal Muscles - Help move bones (voluntary)
What causes the lungs to take in oxygen and push out carbon dioxide (C02). (What organ/muscle helps the lungs to operate?)
The diaphragm. When the diaphragm contracts you breathe in and when it relaxes you breathe out.
This type of blood vessel carries oxygen rich blood away from the heart to all parts of the body.
Arteries
What part of the nervous system helps sends signals to and from the brain? (Also known as the highway of the nervous system)
The Spinal Cord
Which part of the digestive system absorbs nutrients from food?
The small intestines
Cords of connective tissues that attach muscles to bones (you can feel one on the inside of your elbow).
Tendons
Which system does the respiratory work with to transport oxygen to all parts of the body?
The Circulatory system. The oxygen travels through the blood stream.
What system does the cardiovascular system work with to send oxygen and nutrients to all parts of the body?
The respiratory system
How do messages get to and from the brain to all parts of the body
The Nerves
What is inside your stomach that helps to break down food and separates the nutrients inside of food?
Stomach Acid
How do muscles move bones? Think about how the bicep and tricep help move the arm.
One muscle Contracts (or squeezes) and the other one relaxes. This pulls the bone in a certain direction to make it move.
To bend the arm the bicep contracts and the triceps relaxes. The opposite happens to straighten the arm.
What are the structures in the lungs that convert oxygen to carbon dioxide? They are typically known as "tiny air sacs"
Alveoli
This type of blood vessel carries oxygen poor blood from the body back to the heart?
Veins
What body system does the nervous system control?
All of them
Skeletal, muscular, cardiovascular, respiratory, and digestive (and others we haven't learned!!)
Which body system works with the digestive system to help transport nutrients all throughout the body?
Circulatory System
