100

$100: What is the main organ for digestion?


- The stomach is the primary organ for digestion

100

$100: What is the main function of the lungs?



- To take in oxygen and remove carbon dioxide from the body

100

$100: What is the primary function of the heart?



- To pump blood throughout the body

100

$100: What are the two main types of muscles?



- Voluntary (skeletal) muscles and Involuntary (smooth) muscles

100

$100: How do the digestive and circulatory systems work together?



- The circulatory system transports nutrients absorbed by the digestive system to all body cells

200

$200: What is the function of the stomach?


 To break down food using stomach acids and begin the process of chemical digestion

200

$200: What is the role of the diaphragm in breathing?



- To help muscles contract and expand, allowing air to move in and out of the lungs

200

$200: What are the three main types of blood vessels?



- Arteries, Veins, and Capillaries

200

$200: How do bones and muscles work together?



- Muscles attach to bones via tendons, allowing movement when muscles contract and relax

200

$200: What role does the respiratory system play in the circulatory system?




- Provides oxygen to blood, which is then circulated throughout the body

300

$300: Name the process that breaks down food into nutrients


- Digestion (specifically mechanical and chemical digestion)

300

$300: Name the pathway air takes when you inhale



- Nose/Mouth → Trachea → Bronchi → Lungs

300

$300: How does blood travel through the body?



- Through a continuous circuit powered by the heart, moving from the heart to organs and back again

300

$300: Name one function of the skeletal system



- Provides structure, protection for organs, and enables movement

300

$300: How do muscles and bones interact for movement?



- Muscles pull on bones at joints, causing movement through contraction and relaxation

400

$400: What role do enzymes play in digestion?


- Enzymes help break down complex food molecules into simpler nutrients that the body can absorb

400

$400: What gas do we breathe in and out?


- Breathe in: Oxygen

- Breathe out: Carbon dioxide

400

$400: What is the role of red blood cells?



- To carry oxygen to body tissues and carry carbon dioxide back to the lungs

400

$400: What is the role of tendons and ligaments?



- Tendons connect muscles to bones

- Ligaments connect bones to other bones

400

$400: Why is oxygen important for the digestive system?



- Oxygen helps cells in the digestive system produce energy to break down food

500

$500: What is the difference between the small and large intestine?


- Small intestine: Absorbs most nutrients from food

- Large intestine: Absorbs water and processes waste before elimination

500

$500: How does the respiratory system help in gas exchange?


- Oxygen moves from air in the lungs into the bloodstream, while carbon dioxide moves from the blood into the lungs to be exhaled

500

$500: What is the importance of the circulatory system in nutrient distribution?


- To transport nutrients, oxygen, and hormones to all parts of the body

500

$500: How does the musculoskeletal system support movement?


- By providing a framework of bones, joints, and muscles that work together to enable motion

500

$500: How do all four systems cooperate to maintain homeostasis?


- Each system supports the others, working together to keep the body functioning properly, balanced, and healthy
