What is systemic physiology?
physiology is a subfield biology that focuses on studying the function of the human body, including how the main processes work on cellular and molecular levels. Systemic physiology includes learning about physical structures, organs forming different body systems and how everyone is. Although the primary focus of the physiology of systems is on physical function, it makes frequent references to anatomy because it discusses the function of individual structures. Body elements that often occur in a study of systems physiology include physiological processes, regulatory mechanisms and their feedback systems, cardiovascular system and neurotransmitters. Through the five senses, the human body constantly receives information about the surroundings in the form of external stimuli, which works to maintain the balance Called Homeostasis.
The control mechanisms are either positive or negative feedback systems. For example, if body temperature becomes too high or drops below normal, this condition actually triggers a reaction,that will face the change, reverting back to the correct extent. It is a negative feedback system and most biofeedback processes fall into this category. With positive feedback mechanisms, this process will not turn, but amplified as in childbirth. Each contraction triggers more and strength and intensity increase with each of them and do not end until the child is born.
The cardiovascular system is also part of systemic physiology, which includes heart expenditure, blood pressure regulation and cardiac rhythm and nervous system. A circulation system that consists of heart, blood and blood vascorts, including oxygen, hormones and waste. The nervous system is divided into central and peripheral - while the central nervous system includes brain and spinal cord, peripheral refers to all other nerves. Neurons are able to transmit electrical pulses that are useful to carry basic information on howo are external and inner stimuli such as pain.
systemic physiology of nerve cells involves the way in which the impulses lead and how they are transmitted. Neurotransmitters are chemicals that play a key role in passing signals to receptors and their effects are either excitatory or inhibitory. Some neurotransmitters are responsible for stimulation while others balance the mood. Medicines, alcohol, stress and diet affect the function of neurotransmitters.
Sometimes normal function is disrupted and pathophysiology is a system of systemic physiology that studies the conditions of the disease and how they specifically affect the body. Strathology is involved in this, but focuses on what is physically happening as a result of illness, unlike the actual functioning.
