Question

Describe the different respiratory systems in animals with examples.

Answer 1

There are different respiratory systems in animals, which include

• Skin – In some animals respiration takes place with their moist and slimy skin surface. E.g., leeches and earthworms. Amphibians respire with skin when in water and with lungs when on land. E.g., frogs, newts.
• Air holes – In insects, there are air holes or spiracles present on their body, which enable the entry of oxygen rich air and giving out carbon dioxide rich air. E.g., cockroaches
• Gills – Many aquatic animals have gills, which are made up of filaments having blood vessels or capillaries. The blood in capillaries helps to absorb oxygen in water, transports in the body and gives out carbon dioxide. E.g., Fish
• Lungs – Most mammals respire with lungs, which are sac like spongy organs in the body. E.g. ,monkeys, cats, human beings, etc.
