What is the main organ of the integumentary system?
Skin
Where does digestion start?
mouth
What organ pumps blood throughout the body?
The heart
What type of muscle controls voluntary body movements?
Skeletal muscle
What is the main function of bones?
To support and protect the body
Name one function of the skin.
Protection, temperature regulation, or sensing the environment
What is the main function of the stomach?
To break down food using acid and enzymes
What are the two main types of blood vessels?
Arteries and veins (capillaries are also acceptable)
Name one muscle in your body.
Examples: biceps, triceps, quadriceps, heart, stomach muscles
What is the name of the bone that protects the brain?

In which organ does most nutrient absorption take place?

Which side of the heart carries oxygen-rich blood?
The left side
What type of muscle is found in the heart?
Cardiac muscle
What substance inside bones makes new blood cells?
Bone marrow
Why does the body produce sweat?
To cool the body down (thermoregulation)
What is the role of the villi in the small intestine?
To increase surface area so more nutrients can be absorbed
What is the function of red blood cells?

Why do muscles work in pairs?

What connects bones to bones?

Explain how the integumentary system works with one other system to maintain homeostasis.
Works with the circulatory system to control body temperature; blood vessels widen or narrow to release or conserve heat.
What are the three accessory organs in digestion? (not directly a part of it but help)
liver, gallbladder and pancreas
Explain the difference between pulmonary and systemic circulation.
Pulmonary circulation moves blood between the heart and lungs; systemic circulation moves blood between the heart and the rest of the body.
Describe the differences between skeletal, smooth, and cardiac muscles.
Skeletal: Voluntary, attached to bones
Smooth: Involuntary, found in organs
Cardiac: Involuntary, found only in the heart
Explain how the skeletal and muscular systems work together to allow movement.
Muscles attach to bones; when muscles contract, they pull on bones to create movement.
