Th relationship of the respiratory and circulatory system?
That the respiratory system gives oxygen to the blood cells in the the circulatory system. Also, they both contain thelungs and gives bool.
The Nervous System :
The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought,learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
Through its receptors, the nervous system keeps us in touchwith our environment, both external and internal.
Like other systems in the body, the nervous system is composed of organs, principally the brain, spinal cord, nerves, and ganglia. These, in turn,consist of various tissues, including nerve, blood, and connective tissue. Together these carry out the complex activities of the nervous system.
The various activities of the nervous system can begrouped together as three general, overlapping functions:
o Sensory
o Integrative
o Motor
Millions of sensory receptors detect changes, called stimuli, which occur inside and outside thebody. They monitor such things as temperature, light, and sound from the external environment. Inside the body, the internal environment, receptors detect variations in pressure, pH, carbon
dioxideconcentration, and the levels of various electrolytes. All of this gathered information is called sensory input.
Sensory input is converted into electrical signals called nerve impulses that aretransmitted to the brain. There the signals are brought together to create sensations, to produce thoughts, or to add to memory; Decisions are made each moment based on the sensory input. This isintegration.
Based on the sensory input and integration, the nervous system responds by sending signals to muscles, causing them to contract, or to glands, causing them to produce secretions. Muscles and...
