Game of Animal Organ Systems

Welcome to the game of animal organ systems.

Your task is to help James through all the different ecosystems by answering questions about animal organ systems

The Sea

- How many lungs does a fish have?
- One
- Two
- Nil
Q: Answer
A: Nil

Q: Saltwater fish
- actively takes up salt through gills
- secrete salt through gills (correct)
- has the same salt concentration in the body as in the water
- produces salt by diffusion through its skin

The Beach

Q: How does turtles breathe?
- with lungs (correct)
- with gills
- through the skin
- a combination of gills and skin
- a combination of lungs and skin

Q: The expression "double circulation" means
- it is twice as effective
- the blood runs twice by the heart each turn it runs through the body (correct)
- the blood runs twice by the lungs each turn it runs through the body
- the veins and the arteries are always in contact

The marsh

Q: Which of these animals lack circulation system?
- toad
- earthworm
- mosquito
- flatworms (correct)

Q: What is the respiratory organs of insects called?
- trachea (correct)
- nefridier
- sulphides
- air bags

Q: Amphibians gets rid of CO_2 from cellular respiration, mainly
- through the lungs (correct)
- via gells
- through the skin

Q: Why can we say that "amphibians are partially adapted to life on shore" (Multiple answers possible)
- because frogs live on land, but thrive in the water
- because the reproduction (egg and fry stage) requires water (correct)
- because adult amphibians always go ashore to warm and dry themselves
- because they have to keep the skin moist for gas exchange to occur through the skin (correct)
- because they use a combination of gills, lungs and skin for respiration (correct)

The Forrest

Q: What is excretion?
- separation of faeces products but not urine
- separation of CO_2
- storage of substances that the body needs
- separation of residues from combustion processes in cells (correct)

Q: How is the most of the carbon dioxide (CO_2) in the blood transported?
- as free CO_2
- as carbon acid (H_2CO_3)
- as bicarbonate (HCO_3^-) (correct)
- as CO_2 bound to hemoglobin

The Mountain

Q: The purpose of the air sacs in birds is
- ensure continuous flow of blood through the heart
- ensure continuous flow of O_2 through the lungs (correct)
- make sure that the birds remain lighter in the air
- make sure that the birds have access to oxygen when flying high

Q: Birds that eat fish from the sea, such as guillemots and puffins, consume too much salt. How to solve the problem?
- They drink fresh water.
- The salt is converted into ions and is used in the birds' bodily functions.
- The salt is excreted through a special gland. (correct)
- Salt is used as part of the birds' food.
- The salt reacts with other substances and gets neutralized.
