so that they can breath. If you do not know the respiratory system is used for breathing
Nope. All species have a respiratory system.
Yes, all amphibians, reptiles, mammals, and birds have a nearly identical respiratory system. Ducks are birds.
lungs
As with all mammals, the koala's respiratory system consists of a pair of lungs, a trachea (or windpipe) and the mouth and nose for breathing.
All vertebrates have respiratory systems. Zebras are vertebrates.
Yes, numbats have lungs. Numbats are mammals, and all mammals have lungs and a full respiratory system.
Because when mammals breathe (Respiratory) it causes their blood to circulate (Circulatory) ad they need their blood to circulate to live. Hope this was helpful. :)
Mammals are air-breathing vertebrates. In mammals, respiration takes place in the lungs. Parts of the respiratory system include the lungs, diaphragm, bronchioles, bronchi, and trachea.
The very same as all mammals have (including humans).
Mammals use lungs to collect oxygen from the air, fish use gills to collect oxygen from the water.
Haemoglobin is the respiratory pigmaent of blood in mammals
You need a respiratory system to bring oxygen into your body and to remove carbon dioxide from your body..
