Answers
Answer:
Answer 1
In the trachea, or windpipe, there are tracheal rings, also known as tracheal cartilages. Cartilage is strong but flexible tissue. The tracheal cartilages help support the trachea while still allowing it to move and flex during breathing.

ANSWER
Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land). Aquatic animals may breathe air or extract oxygen that dissolved in water through specialized organs called gills, or directly through the skin. Examples are Whales and Dolphins. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land). Terrestrial animals are animals that live predominantly or entirely on land (e.g., cats, ants, spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g., fish, lobsters, octopuses), or amphibians.
hey mate
here's ur answer....
1 ) Role of cartilage in respiratory system:
There are V-shaped cartilaginous rings on trachea or windpipe .to prevent its collapse....and thus helps in gaseous exchange in respiration to take easily...
2) (i) Terrestrial animals are those who spend most of their life staying on land. So they directly take the air or oxygen from the atmosphere..for their respiration. (ii) And thier main respiratory organ is nose..they breath in oxygen for respiration from their nose.
Whereas
(i) Aquatic animals are those who spend their time staying under water..So they take oxygen from the water which gets dissolved in it and is used by the aquatic animals for their respiration. (ii) And their main respiratory organ is their gills.. they take in oxygen for respiration from their gills.
So frnd i have given here two difference between respiration in aquatic animals and terrestrial animals..
with the function and role of cartilage in respiration.
hope it helps you frnd....
