Other than the nervous system, which other system helps in control and coordination in our body?
Excretory system
Endocrine system
Respiratory system
Digestive system
Endocrine system
In human beings, control and coordination are achieved by two main systems: the nervous system and the endocrine system. The nervous system uses electrical impulses along nerve cells for rapid, short-term responses, while the endocrine system uses chemical messengers called hormones secreted into the bloodstream for slower, long-lasting physiological regulation.

Think of the nervous system as a rapid telephone network delivering instant messages, while the endocrine system is like a postal mail service that delivers letters more slowly but reaches every part of the body.
NE = Nervous & Endocrine systems work together for body control.
The endocrine system consists of various ductless glands (such as the pituitary, thyroid, adrenal glands, and pancreas) that synthesize and secrete hormones directly into the blood. These chemical messengers travel to target organs to regulate metabolism, growth, development, and homeostasis.
Control and coordination in multicellular animals is performed by the nervous and endocrine systems.
The nervous system relies on neurons and neurotransmitters for rapid communication.
The endocrine system relies on ductless glands releasing hormones into the bloodstream.
Hormones act as chemical messengers that regulate various metabolic activities and growth.
Ensures precise and rapid reaction to external stimuli via nervous system.
Provides continuous regulation of metabolic processes over long periods via endocrine system.
Regulation of blood glucose levels by insulin and glucagon.
Fight-or-flight response mediated by adrenaline and the sympathetic nervous system.
| Feature | Nervous System | Endocrine System |
|---|---|---|
Medium of transmission | Electrical impulses (nerve signals) | Chemical messengers (hormones) |
Speed of action | Very rapid | Relatively slow |
Option A (Excretory system) is responsible for waste removal and osmoregulation.
Option C (Respiratory system) deals with gas exchange (O2тАЛ and CO2тАЛ).
Option D (Digestive system) breaks down food for nutrient absorption.
B is correct тАФ Endocrine system works along with the nervous system to achieve control and coordination in the human body.
Remember that plant control and coordination relies solely on chemical messengers (plant hormones or phytohormones) as they lack a nervous system entirely!
