List 3 of the functions (jobs) of the skeletal system
1. Support
2. Protects vital organs
3. Produce red 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 breakdown large molecules into smaller ones for the body to use for energy.
The skin, lungs and kidneys work together to?
Help eliminate body wastes.
What is the main functions of the muscular system?
Movement
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 is the major organ of the nervous system?
The Brain
Cells remove waste from their cytoplasm by passing it through the cell membrane and out of the cell. What two human body systems perform similar functions?
Digestive and Excretory Systems
What is the first line of defense against pathogens?
Skin
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
In the human body, what part of the central nervous system connects with other nerves outside of the central nervous system?
The Spinal Cord
Which part of the digestive system absorbs the most nutrients from food?
The small intestine
What system in the human body contains the pituitary gland, hypothalamus gland, and thyroid gland?
Endocrine System
1. Where two or more bones meet together.
2. Cords of connective tissues that attach muscles to bones (you can feel one on the inside of your elbow).
1. Joints
2. 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.
Which other system does the cardiovascular system work with to send oxygen 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 organ in the digestive system produces acid to break down food?
Stomach
What system does the largest organ, the skin belong to?
The integumentary system
How do muscles move bones? Think about how the bicep and tricep 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.
(Contract and relax)
After we breathe in oxygen to our lungs, where does the oxygen go before it is sent to all parts of the body?
Oxygen is sent to the heart then it is transported to all parts of the body through the blood stream.
Nutrients being absorbed into the bloodstream most closely describes a relationship between what two systems?
circulatory system and the digestive system
What body system does the nervous system control?
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
What is the common characteristic of all living things?
They are made up of cells
