Hierarchy of Life
The basic structural and functional unit of all living organisms.
What is a cell?
The main organ system responsible for breaking down food into usable nutrients.
What is the Digestive system?
The gas taken in by the respiratory system that cells need to release energy from food.
What is oxygen (O2)?
True or False: An organ system can function completely independently without relying on any other systems.
What is False?
"Just pumped 2,000 gallons of blood today! #NeverNotWorking #Grindset"
What is the heart?
A group of similar specialized cells working together to perform a job.
What is a tissue?
The transport system that carries absorbed nutrients from the stomach/intestines to the rest of the body.
What is the circulatory system?
The organ system that uses blood vessels to deliver oxygen to working body tissues.
What is the circulatory system?
The two main things the circulatory system must constantly deliver to working muscle cells during exercise.
What are oxygen and glucose?
"Gotta love exchanging O2 for CO2 with my capillary besties every second! #BreatheInBreatheOut"
What is the respiratory system / lungs?
List the 5 levels of biological organization in order from smallest to largest.
What is Cell --> Tissue --> Organ --> Organ System --> Organism?
The simple sugar molecule from digested food that body cells use for energy.
What is glucose?
The waste gas produced by cells that is carried back to the lungs and exhaled.
What is carbon dioxide (CO2)?
If you start running and your cells need more oxygen, what does your heart (circulatory system) do to compensate?
What is beats / pumps faster?
"Flexing our millions of microscopic folds to maximize surface area for nutrient absorption! #AbsorbTheGoodVibes"
What are villi (or microvilli)?
The stomach, heart, and lungs are all examples of this level of organization.
What is an organ?
Microscopic, finger-like folds in the small intestine that absorb nutrients into the blood.
What are villi (or microvilli)?
Why do both lung alveoli and blood capillaries have super thin, single-cell thick walls?
What is so gases can diffuse quickly/easily?
Name two different organ systems that work together to remove waste products from your cells.
What are any two of Circulatory, Respiratory, or Excretory?
"Just absorbed water from the soil and shipped it straight up the stem to the leaves! #ToTheShoot"
What is the root system (or roots)?
Explain why the heart is classified as an organ rather than a tissue.
What is it is made of multiple different tissue types working together?
If a disease destroys intestinal villi, which other system suffers because cells can't get energy to contract or function?
What is the muscular (or nervous) system?
Tiny holes on a leaf's surface that allow for gas exchange and water loss in plants
What is Stomata
The two systems that work together to form your immune system?
What are Integumentary and Lymphatic systems
"Carrying water strictly ONE WAY from the roots all the way up to the leaves! #WaterPipeline #UpwardMobility"
What is xylem (or xylem tissue)?
