Question

Which of the following organ systems forms a communication and coordination network throughout the whole body of the organisms?
A.Digestive system
B.Respiratory system
C.Circulatory system
D.Nervous system
E.Skeleton system

Answer 1

Hint: In the body of the organisms all systems coordinate with each other to perform all the vital functions the body which are useful for life.

Complete step by step answer:
1 :- Digestive system :- Group of organs which simply break the food into small components and convert it into a form which is easy for absorption. Body gets all the energy from that food item only.
2 :- Respiratory system :- it is a group of organs which are responsible for the exchange of gases and it inhales oxygen from the environment and exhales carbon dioxide to the environment. The availability of oxygen in the body is fulfill by respiratory system
3 :- circulatory system :- the major components are heart and the blood heart pumps the blood and it get transfer to the whole body and oxygenated blood provide oxygen to the whole body and deoxygenated blood leaves carbon dioxide to the lungs
4 :- Nervous system :- it is responsible for the communication and coordination of different organs with each other. If they provide signals to all the organs and organ systems to do their work.
5 :- skeleton system :- it provides proper shape and strength to the body. All the soft and vital organs of the body are placed safe inside the skeleton system.
Hence the nervous system is the system which is responsible for communication and coordination on different organisms.

Option D is correct.

Note:
Nervous systems have a net of neurons which is present all over the body and the signals are transferred through these neurons. Neurons consist of three parts- dendrites, cell body and nerve ending. in Myelinated neuron signal transfer through saltatory movement, this speeds up the signal.
