Nervous System
$100: This system gathers and interprets information to help maintain homeostasis.
➡ What is the nervous system?
$100: This organ pumps blood throughout the body.
What is the heart?
$100: This process involves taking in food and breaking it down into smaller molecules.
➡ What is ingestion?
$100: This is the primary organ that takes in oxygen and expels carbon dioxide.
➡ What are the lungs?
$100: This molecule carries genetic instructions for all living organisms.
➡ What is DNA?
$200: The part of the brain that maintains homeostasis and controls hunger.
➡ What is the hypothalamus?
$200: These blood vessels carry blood away from the heart.
What are arteries?
$200: This part of the digestive system helps absorb nutrients from digested food into the bloodstream.
➡ What is the small intestine?
$200: These tiny air sacs in the lungs are where gas exchange occurs.
➡ What are alveoli?
$200: The shape of DNA is described as this.
➡ What is a double helix?
$300: These are the cells that transmit signals throughout the body.
➡ What are neurons?
$300: This small blood vessel is where oxygen, carbon dioxide, and nutrients are exchanged with cells.
➡ What are capillaries?
$300: This organ produces bile to help digest fats.
➡ What is the liver?
$300: This structure connects the throat to the lungs.
➡ What is the trachea?
$300: The four nitrogen bases found in DNA.
➡ What are adenine, thymine, cytosine, and guanine?
$400: This part of the nervous system helps the body respond to stimuli and maintains balance.
➡ What is the spinal cord?
$400: These cells are responsible for transporting oxygen throughout the body.
➡ What are red blood cells?
$400: These glands in the mouth release enzymes that begin the process of breaking down food.
➡ What are salivary glands?
$400: This muscle controls the process of breathing by expanding and contracting the lungs.
➡ What is the diaphragm?
$400: The scientist duo credited with discovering DNA’s structure.
➡ Who are Watson and Crick?
$500: The nervous system division that controls involuntary body functions, like heartbeat and digestion.
What is the autonomic nervous system?
$500: The circulatory system transports this type of cell to help the body fight off infections.
➡ What are white blood cells?
$500: This is the last step of digestion, where undigestible food is expelled from the body.
➡ What is defecation?
$500: This system works with the circulatory system to deliver oxygen from the lungs to cells and remove carbon dioxide.
➡ What is the respiratory system?
$500: This enzyme unzips DNA during replication.
➡ What is helicase?
