How does chemical coordination take place in animals.
Answers
Answer:
Excretion
Explanation:
The animals and birds and human intake food and excrete stools
Chemical coordination takes place in animals with the help of hormones. Hormones are the chemical fluids that are secreted by the glands of the endocrine system. Hormones regulate the overall growth and development of the animals.
Endocrine glands----> hormones-----> blood----> organs / tissues----> biochemical / physiological activity.
Chemical coordination in multicellular organisms take place through the special chemical substances called hormones, which are produced in endocrine glands.
These chemicals unlike nerve cells, reach all the cells of the body and bring about desirable changes as instructed by the brain and spinal cord. This is done by using a hormone named adrenaline. It is directly secreted into the blood and carried to different parts of the body.
The heart, beats faster to supply more oxygen to our muscles. The breathing rate also increases. All these responses enable the animal body to be ready to face the situation. Such hormones constitute a second way of control and coordination.
