Muscular & Skeletal
List the five main functions (jobs) of the skeletal system
1. Support/Structure
2. Shape
3. Movement
4. Protects vital organs
5. Make Blood Cells
1. What is the main function of the respiratory system?
2. What does it give to the body and what does it get rid of?
1. Breathing
2. 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
Explain what voluntary and involuntary muscles do. Give an explain of each.
Voluntary- does when thought about (raising your hand)
Involuntary- does without having to think about (heart beating, digesting food)
What are the four main parts of the respiratory system?
Nose, 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
Is it true that the digestive system is more important than the circulatory system?
No, both systems and processes are essential for life functions!
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 helps the lungs to operate?
The diaphragm. When the diaphragm contracts you breathe in and when it relaxes you breathe out.
1. Carries oxygen rich blood away from the heart to all parts of the body?
2. Carries oxygen poor blood from the body back to the heart?
1. Arteries
2. Veins
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
Explain how the skeletal system is different from the nervous system.
Skeletal- protects the brain (skull)
Nervous- sends messages to and from the brain
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.
Which two systems does the cardiovascular system work with to send oxygen and nutrients to all parts of the body?
The respiratory system and the digestive system
What do you have all over your body that gathers information/signals to send to the brain?
The Nerves
What is inside your stomach that helps to break down food and separates the nutrients inside of food?
Stomach Acid/Bile
How do muscles move bones? Think about how the biceps and triceps help move the arm.
Muscles work in pairs and pull on bones. One muscle Contracts (or squeezes) and the other one relaxes.
To bend the arm the bicep contracts and the triceps relaxes. The opposite happens to straighten the arm.
After we breathe in oxygen to our lungs, where does the oxygen go?
Oxygen is sent to the heart then it is transported to all parts of the body through the blood stream.
Describe the system and how it functions. Include major parts and what they do for the system.
Important parts: Blood Vessels, Heart, Blood
Blood (full of nutrients, oxygen, and waste) is pumped through the body. It is transported through our blood vessels and delivers what we need to our cells. Carbon dioxide is exchanged within our lungs to be exhaled.
What body system does the nervous system control?
*Daily Double*
All of them
Skeletal, muscular, cardiovascular, respiratory, and digestive
Which body system works with the digestive system to help transport nutrients all throughout the body?
Circulatory System
