Structural Organisation in Animals Important

Structural organisation in animals important points: Animals are the multicellular organisms composed of the cells, tissues, organs, and the organ systems that work together to perform the various specific functions. There are three types of tissues: epithelial, connective, and the muscle tissue.

The main organ systems in animals includes digestive, circulatory, respiratory, nervous, and the reproductive systems. Animals can be classified into the two main groups: invertebrates without a backbone and the vertebrates with a backbone. The structural organization of the animals varies greatly and can change over time through the process of evolution and adaptation.

The study of the animal structure is important for understanding the animal behavior, physiology, and evolution, and has practical applications in the fields such as medicine and the veterinary science.

1. The animals are the multicellular organisms that are made up of different tissues, organs, and the organ systems.

2. Smallest unit of an animal is cell, which is the basic and structural unit of life.

3. The Tissues are the group of similar cells that performs specific function in the body.

4. The Organs are made up of two or more types of tissues that works together to perform a specific function.

5. The Organ systems are groups of organs that works together to perform a specific function.

6. The three main types of tissues that are found in the animals are the epithelial tissue, connective tissue, and the muscle tissue.

7.  The Epithelial tissue covers the surface of body and lines the internal organs of the body.

8. The Connective tissue provides support and protection to the body’s organs.

9. The Muscle tissue is responsible for the movement and contracting to produce the force.

10. Main organ systems in the animals includes the digestive system, circulatory system, respiratory system, nervous system, and the reproductive system.

11. Digestive system breaks down the food, absorbs the nutrients, and eliminates the waste.

12. Circulatory system transports the oxygen, nutrients, and the hormones throughout the body.

13. Respiratory system brings in oxygen and removes the carbon dioxide.

14. Nervous system controls  body’s response to stimuli and coordinates actions of the other systems.

15. Reproductive system produces the offspring.

16. Animals can be classified into the two main groups based on their structural organization. These are invertebrates and vertebrates.

17. Invertebrates are the animals without a backbone, such as the sponges, jellyfish, and the insects.

18. Vertebrates are the animals with a backbone, such as the fish, reptiles, birds, mammals, and the human beings.

19. Structural organization of the animals varies greatly among the different species, from simple to complex.

20. Animals have developed various adaptations and structures to help them survive in various environmental conditions.

21. Some of the animals have specialized structures such as the tentacles, gills, and fins that allows them to capture the food or move through their environment.

22. Animals also have structures that help them to protect themselves from the predators or the environmental threats.

23. The structural organization of the animals can change over time through the evolution and adaptation.

24. Some animals, such as the cnidarians, undergoes  metamorphosis, a process of transformation from one stage of life to another stage.

25. The study of the animal structure is important for understanding the animal’s  behavior, physiology, and evolution, and can also have the practical applications in the fields such as medicine and veterinary science.
