introduction
life-active Basic Features
Metabolism (the most basic characteristics)
Substance metabolism
Energy metabolism (accompanied by material metabolism)
Excitability
The ability and characteristics of all living cells and tissues to respond to stimuli.
excitable cells
nerve cells
muscle cells
gland cells
reaction classification
excited
Relatively static becomes active Functional activity changes from weak to strong
inhibition
Relative activity changes to relative inactivity Functional activity changes from strong to weak
stimulus classification
physical
Chemistry
biological
psychosocial
Three conditions for reaction
1. Sufficient stimulation intensity
2. Sufficient stimulation time
3. Appropriate intensity-time change rate
Adaptability
physiological adaptation
behavioral adaptation
biological rhythm
reproduction
senescence
1. Morphological changes.
2. Decreased physiological functions
body in the ring environmental relationship
external environment environment
Category one
natural environment
social environment
Category 2
physics
biology
Chemical
social psychological factors
Internal environment and homeostasis
body fluid
intracellular fluid
extracellular fluid
Internal environment
The role of internal environment
Provide materials for cells
Receiving cell waste
Provide conditions for cell activity
Steady state
Physiology refers to a state in which various physical and chemical factors of the internal environment remain relatively stable as homeostasis.
On the one hand, it means that the physical and chemical properties of the extracellular fluid remain relatively stable.
On the other hand, it means that the stable state is not fixed, but constantly changing within a certain range.
body control system
feedback system
The information sent by the controlled part that can affect the controlling part is called feedback information The activity of the controlled part in turn affects the activity of the controlling part is called feedback
Negative feedback
Helps maintain homeostasis It is of great significance for maintaining normal physiological activities
Positive feedback
Its physiological function is to promote a certain physiological activity process to reach a climax quickly and exert its maximum effect.
Urination, defecation, ejaculation, blood clotting and childbirth
Regulation of physiological functions of the body
neuromodulation
Basic adjustment method - reflection
unconditioned reflex
Conditioned reflex
Structural basis - reflex arc
Receptor, afferent nerve, nerve center, efferent nerve, effector
Features: rapid response, accurate, limited action site and short action time
body fluid regulation
Chemical material
hormone
Special chemicals produced by tissues and cells
cellular metabolites
Features: slow response, long duration of action, wide range of action
Classification
distant secretion
Paracrine
autocrine
Some glands receive direct or indirect control from nerves. In this case, humoral regulation becomes an extension or supplement of neural regulation, which is called "neuro-humoral regulation"
self-regulation
The range of influence is limited, the adjustment range is small, and the sensitivity is low.
