Question

- Describe briefly the respiratory organs of the following:
Humans, Earthworms, Cockroach, Fish.explain briefly please ​

Answer 1

Humans

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. ... The blood then collects carbon dioxide and other waste products and transports them back to the lungs, where they're pumped out of the body when we exhale.

Earthworms

Earthworms have no special respiratory organs. Gases are exchanged through the moist skin and capillaries, where the oxygen is picked up by the hemoglobin dissolved in the blood plasma and carbon dioxide is released. Water, as well as salts, can also be moved through the skin by active transport.

Cockroach

In cockroach, respiration takes place through a small openings on the sides of its body called spiracles. ... The respiratory organ of cockroach is known as tracheae. The trachea is a dense networked array of air tubes in the internal system. These tracheae balance the pressure within the system.

Fish

Respiration in fish takes with the help of gills. Most fish possess gills on either side of their head. Gills are tissues made up of feathery structures called gill filaments that provide a large surface area for gas exchange. ... Blood enters and leaves the gills through these small blood vessels.
