Difference between control and coordination ?

Question

Answer

H€¥@.....!!

Coordination refers to the organisation of all the activities in an orderly manner, to achieve unanimity of individual efforts in the pursuit of group goals.

Control of an undertaking consists of seeing that everything is being carried out in accordance with the plan which has been adopted, the orders which have been given, and the principles which have been laid down.

Answer

Control and coordination:

Control and coordination are two important processes that occur in living organisms to maintain their internal stability and respond to external stimuli. While they are closely related, there are distinct differences between the two.

Control:

Control refers to the regulation of various physiological processes within an organism. It involves the monitoring and adjustment of specific parameters to maintain homeostasis. Control mechanisms are responsible for maintaining the optimal functioning of different systems in the body. Some key points about control are:

1. Regulation of processes: Control mechanisms regulate processes such as body temperature, blood pressure, heart rate, and pH levels in the body.

2. Feedback loops: Control is often achieved through feedback loops, which involve sensing changes in the internal or external environment and making necessary adjustments. There are two types of feedback loops: positive and negative feedback.

3. Positive feedback: In positive feedback, the response amplifies the initial stimulus, leading to further deviation from the normal state. For example, during childbirth, the release of oxytocin enhances uterine contractions, leading to increased release of oxytocin, and so on.

4. Negative feedback: Negative feedback is the most common control mechanism in living organisms. It works to counteract any deviation from the normal state and restore equilibrium. For instance, when body temperature increases, negative feedback mechanisms initiate sweating and dilation of blood vessels to cool down the body.

Coordination:

Coordination refers to the integration of different organs, systems, or body parts to work together harmoniously towards a common goal. It involves the communication and synchronization of activities to carry out complex functions. Some key points about coordination are:

1. Integration of activities: Coordination integrates the activities of different organs, tissues, and cells to achieve a specific function. For example, during exercise, the respiratory, circulatory, and muscular systems work in coordination to supply oxygen to muscles and remove waste products.

2. Communication and signaling: Coordination requires effective communication between different parts of the body. This communication is achieved through chemical signals called hormones and nerve impulses. Hormones are secreted by endocrine glands and transported through the bloodstream to target organs, while nerve impulses travel through specialized cells called neurons.

3. Central and peripheral coordination: Coordination can be classified into central and peripheral coordination. Central coordination involves the central nervous system, which includes the brain and spinal cord. Peripheral coordination involves the coordination of activities by peripheral nerves and endocrine glands.

4. Role of receptors: Receptors play a crucial role in coordination as they detect stimuli and initiate appropriate responses. They are specialized structures that respond to specific changes in the environment, such as light, temperature, pressure, or chemicals.

In summary, control and coordination are interrelated processes that ensure the proper functioning of living organisms. Control mechanisms regulate specific parameters to maintain homeostasis, while coordination integrates activities between different parts of the body to achieve common goals. Both processes are essential for the survival and well-being of organisms.
