Nope. All species have a respiratory system.
so that they can breath. If you do not know the respiratory system is used for breathing
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.
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.
Mammals use lungs to collect oxygen from the air, fish use gills to collect oxygen from the water.
The very same as all mammals have (including humans).
Haemoglobin is the respiratory pigmaent of blood in mammals
Platypuses are mammals, so they use the same type of respiratory system as other mammals - mouth, nose and lungs. They do not breathe underwater.
There is very little difference in anatomy and physiology. Dogs are mammals.
