Do all animals other than man have self consciousness?
No. There are animals without any nervous systems, like sponges.
Which systems provide a benefit to the nervous system?
the skeletal and muscular system provide a benefit to the nervous system. without them, when your brain tells you to reach for a cup, those systems wont be there to physically do the action.
How could damage to the nervous system affect another body system?
none of the other body systems could function without direction from the nervous system or energy provided by the digestive and circulatory systems.
What systems are involved with breathing?
The respiratory system has primary responsibility for breathing, but it could not accomplish this function without the skeletal, muscular, nervous, and circulatory systems.
How do your body systems work without other systems in the body?
Your body is the sum of all its systems. There are no "other systems". All the body's systems have to be working together or the body will not be able to stay alive.
Can a penguin live without a head?
No higher animal can live without a head. (Decapitated insects can sometimes move around for a considerable time, however, because their nervous systems are not as centralized.)
Why is cell specialisation important to an organism?
Without cell specialisation, the organism can never become more than a simple protozoan because it's one cell must perform all of the metabolic functions to keep the cell alive and allow it to reproduce. It is the development of cells that work together to perform one function for the benefit of the entire colony of cells that allowed advanced animals and plants to evolve. Eventually, some organisms developed highly specialized tissues that became organ systems, and so advanced animals with large bodies(mammals, for example) and advanced plants (trees, for example), also with large bodies, were able to evolve and thrive. In our bodies, specialized tissues become organs with one main function, and we call these organs 'systems'. We have digestive, circulatory, respiration, reproduction, endocrine, nervous systems and more, all of which perform specific functions to support the entire body. In trees, there is xylem tissue to bring water up from the roots to the leaves, phloem tissue to bring glucose down from the leaves to the roots, structural ring systems which allow the tree to grow tall and wide, etc so the result is a large plant with specialized tissues to support the entire tree. The more specialized and seperate the systems, the more highly advanced the organism.
Functions you would lose if unable to use your respiratory system?
Circulatory, nervous, endocrine, lymphatic, and digestive systems all fail without adequate respiration.
What are plants without specialized conducting tissues?
plants without specialized conducting tissues are called nonvascular plants
Which division of the nervous system is dedicated to subconscious functions?
The autonomic nervous system is dedicated to regulating subconscious functions such as heart rate, digestion, and breathing. It has two main branches - the sympathetic and parasympathetic nervous systems, which work together to maintain homeostasis in the body without conscious effort.
What is the nervous system that functions without conscious effort?
The autonomic nervous system functions independently and continuously without conscious effort.
Will you die without the nervous system?
There is no question that a human being cannot live without a nervous system.
