The killer whales have a very large distribution, and they can be found in all oceans, apart from the Southern Ocean. It is noted though that the population density of the killer whales differs from place to place. The higher concentrations are found around the Arctic and Antarctic Circles, where there's cool rich waters, while in the lower latitudes they are much rarer. The reason for this probably lies in the fact that most of the animals that are considered to be the prime food source of the killer whales are living in this rich cold waters.

How respiratory system works?
What are the components of respiratory system?
Explanation:
Our lungs expand when we breathe in through our nose and mouth. That air moves down our trachea, through your bronchi and into the bronchioles, where it enters your alveoli where blood capillaries are passes which load oxygen and unload carbondioxide gas which can be removed from our body through exhalation. Nose, mouth, throat (pharynx), voice box (larynx)
, windpipe (trachea)
, large airways (bronchi) and lungs are the main components of our respiratory system.
