Receptors that provide animals with information from the external environment are located in the:
- ears
- skin
- tongue
- eyes
- nose
These receptors are known as sensory receptors as they perceive the changes that occur in the external environment and transmit the information to the nervous system.
The name of these receptors located in the respective organ is as follows :
1. Ear - auditory receptor
2. Skin - mechano (cutaneous) receptors
3. tongue - taste receptors
4. eyes - Photoreceptors
5. nose - olfactory receptors
An example of how it detects the changes in the external environment can be understood as follows :
The substances that have odor produce chemicals known as odorants which bind to the olfactory receptors located in the nose which then produces electric signals which are transmitted via the nerves to the olfactory bulb in the brain and the smell is detected.

Answer:
The respiratory system aids the supply of oxygen to the blood and the evacuation of carbon dioxide. when the heart takes in blood that as shortage of oxygen and abundance of carbon dioxide, the pulmonary arteries pumps such blood to the lungs.
As the lungs increases due to inflow of fresh air from the surroundings, oxygen is transported to enrich low-oxygen blood, and transport the carbon dioxide out of the lungs.
This freshly oxygen rich blood which now have a rich amount of hemoglobin is transported to the heart which then pump or circulated it to the entire body.
