Digestive System
What is the function of the digestive system?
To break down food and give nutrients into the body
What is the function of the respiratory system?
Exchanging gases with the environment
What is the function of the circulatory system?
Deliver oxygen to individual cells and remove carbon dioxide from them.
What is biodiversity?
The number of species in an ecosystem
What is photosynthesis?
When plants or protists take energy from the sun to create glucose (food)
Name three organs of the digestive system
Name three parts of the respiratory system
Nasal cavity
Oral cavity
Epiglottis – flap that lets air into trachea and food into esophagus.
Pharynx – passageway from nasal and oral cavities to trachea
Trachea
Bronchial tubes
Lungs
What is Oxygen's path through the circulatory system?
Capillaries -> arteries -> heart ->? arteries -> capillaries -> cells.
What is mutualism? Give and example.
When two organisms of different species have a partnership where both benefit.
What is cellular respiration?
When a cell breaks down glucose (food) into usable energy.
What are the functions of the Liver?
Makes bile to break down food
Which harmful waste leaves the blood and travels through the lungs before leaving the body?
Carbon Dioxide
How are veins, arteries, and capillaries similar?
All three transport blood around the body.
What is an Autotroph?
An autotroph is a producer in a food chain. It's an organism that makes its own food.
What is the chemical equation for cellular respiration?
glucose + oxygen = water + carbon dioxide + ATP
What do the small intestine and large intestine do?
Small intestine – extracts nutrients
Large intestine – extracts water and some vitamins
What is the Pharynx?
Pharynx – passageway from nasal and oral cavities to trachea
How are veins, capillaries, and arteries different?
Veins and arteries are large, while capillaries are small. Also, arteries only carry oxygenated blood, veins only carry blood with carbon dioxide, and capillaries carry both.
What is a heterotroph?
A heterotroph is a consumer. It's an organism that needs to eat food for energy.
What is the chemical equation for photosynthesis?
water + carbon dioxide + Energy = glucose + oxygen
Which sequence shows the pathway that food takes in the digestive system?
Esophagus, stomach, small intestine, large intestine
What is the function of the Alveoli?
Alveoli act as the gateway between the lungs and the bloodstream. Alveoli have extremely thin cell membranes, which allow oxygen to cross from the lungs into the blood stream. Those thin membranes also allow carbon dioxide to cross from the blood stream back into the lungs
How do the circulatory and the respiratory system depend on one another?
Oxygen collected by the respiratory system is carried through the body by the circulatory system
What are the six characteristics of life?
1. Made of cells
2. Movement
3. Reproduction
4. Growth and Development
5. Response to Stimuli
6. Energy Use
If you were picking an organism to send into outer space, where there is no air, would you chose an prokaryotic or eukaryotic organism to send? Why?
Prokaryotic – they don’t need oxygen for cellular respiration.
