Structure
What is the basic unit of life?
cell
What are the main functions of the digestive system?
Break down food, absorb nutrients, send to the bloodstream, and remove waste.
What is the primary organ of the respiratory system?
Lungs
What are the two substances that move throughout the circulatory system?
Where do they receive them from?
nutrients (digestive) and oxygen (respiratory).
What are the 3 types of muscles?
Smooth, Cardiac and Skeletal
What is a group of similar tissues called?
organ
Which organ is responsible for absorbing nutrients?
Small Intestines
What is the function of the diaphragm?
Helps the lungs expand and contract during breathing.
What type of muscle is your heart?
Cardiac
What is the difference between involuntary and voluntary muscles?
Involuntary - muscles that work on their own without you having to think about it
Voluntary - muscles you can control.
What is an organ system made up of?
organs
Explain the difference between the trachea and the esophagus.
The trachea takes in oxygen and sends it to the lungs. Also, removes carbon dioxide from the body.
The esophagus transports liquids/foods from the mouth to the stomach, aids in the process of digestion.
Name the gas we inhale.
Oxygen
Explain the difference between white blood cells and red blood cells.
White blood cells - immunity fighters
Red blood cells - carry oxygen and nutrients
What are two functions of the skeletal system?
Answers vary - let's discuss
What best describes tissues?
A group of cells that work together to perform a specific function.
What is the function of the spinal cord?
Sends messages from the brain to the rest of the body (vice versa)
Why would we increase our breathing rate when exercising?
Certain organs (muscles and brain) need more oxygen and less carbon dioxide. When you exercise, you produce more CO2, so you breathe heavier to expel it while also increasing the amount of oxygen you intake.
How do the muscular and circulatory systems work together?
The circulatory system supplies muscles with oxygen and nutrients for function and removes waste products like carbon dioxide, while the muscular system assists blood return to the heart.
Explain to the person nearest you - how do the muscles and skeletal system work together to move.
Muscles pull on tendons that are attached to the bones.
Name the levels of organization in order from smallest to largest.
Cell-Tissue-Organ-Organ System-Organism
Explain how the digestive and nervous systems interact.
Answers might vary, let's discuss.
Explain how the respiratory and circulatory systems work together.
The respiratory system takes in oxygen and exchanges it with the carbon dioxide collected from the circulatory system. This occurs in the lungs.
How do your nervous system and circulatory system work together?
Your brain (nervous system) controls your heart rate and blood flow, while your circulatory system provides oxygen to function properly.
What is the difference between organs and organ systems?
Organs are groups of tissues that work together to perform the same function. Organ systems are multiple organs that work together to complete a function.
