Question

What is the importance of organized organ system? (a) Optimum efficiency of cells (b) Coordinated activity of cells (c) Both (a) and (b) (d) None of these

Short answer

The correct answer is (c) Both (a) and (b).

Step-by-step solution

Understanding the Concept of Organized Organ System

An organ system is a group of organs that work together to perform one or more functions. Each does a particular job in the body, and is made up of certain tissues.

Analyzing Option A

Organ systems increase the 'Optimum efficiency of cells'. This is true because an organized organ system aligns organs into systems that can work together to accomplish complex tasks that individual cells or organs can't do alone.

Analyzing Option B

'Coordinated activity of cells'. This is also true, because without an organized organ system, the different cells in our body wouldn't be able to communicate and coordinate as effectively, leading to a breakdown in overall function.

Analyzing Option C and D

Given the above explanations, both (a) and (b) reasons are correct, so the answer (c) is valid. Option (d) can be excluded because it contradicts the proven importance of the organized organ system given in statements a and b.

Key concepts

Cell Efficiency

Organized organ systems can significantly boost the efficiency of cells. Think of cells as tiny workers each with a specific role to perform. In isolation, a cell may only achieve so much due to limited resources and capabilities. However, within a system, cells are grouped into tissues and organs, each contributing to a collective function.

When organs form a system, they ensure that cells operate in an optimal environment. This means that nutrients are delivered efficiently, waste is expelled effectively, and conditions such as temperature and pH are maintained.

• Organ systems facilitate nutrient and oxygen provision.
• They enhance waste removal.
• Regulation of bodily functions allows peak cell performance.

Ultimately, this collaboration enhances the overall efficiency of cells, leading to better health and function of the whole organism.

Coordinated Cellular Activity

The coordination among cells is pivotal for maintaining a harmonious and functioning organism. In an organized organ system, cells do not work in isolation but interact to achieve a common goal.

Through organized communication mechanisms, cells send signals that can instruct other cells on actions to take or when to stay dormant. This is often managed by chemical signals called hormones or even electrical impulses in nerve cells.

• Hormones facilitate long-distance intercellular communication.
• Neural signals provide short-distance, immediate responses.
• Cell junctions allow direct coordination between adjacent cells.

Such coordination ensures that processes like muscle contraction, immune response, and digestion happen smoothly and timely, preventing chaos within the body.

Tissues and Organs

Understanding tissues and organs is vital to appreciate how organ systems function. Tissues are collections of similar cells grouped together to perform a specific job. This can include muscle tissues, nervous tissues, connective tissues, or epithelial tissues, each vital to different functions.

When various tissues amalgamate, they form organs, each having distinct tasks in the body. For example, the heart is an organ made up of muscle tissue, connective tissue, nervous tissue, and blood tissue, all working together to pump blood.

• Tissues collaborate to form organs with unique functions.
• Organs work in systems, enabling complex life functions.
• Organ systems allow for specialization and improved efficiency.

Without this meticulous organization of cells into tissues and organs, survival and sophisticated life functions would not be possible.
