Digestive System
What is the main organ for digestion?
Gastrointestinal tract
What is the main function of the Lungs?
Gas Exchange
What is the primary function of the heart?
Move blood through the body
What are the two main types of muscles?
1. Voluntary (conscious)
2. Involuntary (Unconscious)
How do the digestive and circulatory systems work together?
Digestive- Breaks down food
Circulatory- Spreads it around the body
What is the function of the stomach?
Aids digestion of food with chemical digestion
What is the role of the diaphragm in breathing?
Facilitating inhalation and exhalation
What are the three main types of blood vessels?
1. Arteries
2. Veins
3. Capillaries
How do bones and muscles work together?
Musles contract or extend making the bones move
What role does the respiratory system play in the circulatory system?
They work to provide the body with oxygen and nutrients
Name the process that breaks down food into nutrients?

What role do enzymes play in digestion?
Breaks down carbs, fats, and proteins
What gas do we breathe in and out?
In - Oxygen
Out- Carbon Dioxide
What is the role of red blood cells?
Transport oxygen and carbon dioxide
What is the role of tendons and ligaments?
Tendons- connect bones to muscles
Ligaments- connect bones to bones
Why is oxygen important for the digestive system?
1. Nutrient absorption
2. Enzyme activity
3. Muscle Function
What is the difference between the small and large Intestine?
Small Intestine- Absorption
Large Intestine- Waste
How does the respiratory system help in gas exchange?
Takes in oxygen and gets rid of carbon dioxide through the lungs.
What is the importance of the circulatory system in nutrient distribution?
Transports nutrients from the digestive system to the whole body
How does the musculoskeletal system support movement?
Muscles allow movement and provide protection
How do all four systems cooperate to maintain homeostasis?
All four are needed to do their parts, if one stops the balance is disrupted.
