What Causes Homeostasis Failure?

Internal environment homeostasis means that under normal physiological conditions, the various components and physical and chemical properties of the internal environment of the body change only within a small range, not in a static state, but in a dynamic equilibrium state.

Internal environment

The steady state of the internal environment is not a static state, but is in

Internal environment homeostasis is a necessary condition for cells to maintain normal physiological functions, and it is also a necessary condition for the body to maintain normal life activities. Imbalance of internal environment homeostasis can cause diseases. The maintenance of the internal environment homeostasis depends on the stability of the functional status of various organs, especially the internal organs, the normality of various regulatory mechanisms of the body, and the role of blood ties.

Steady state: The normal body regulates each organ and system to coordinate activities and maintain a relatively stable state of the internal environment. This is called steady state.

The essence of steady state: the chemical composition and physical and chemical properties of the internal environment remain relatively stable

Factors Affecting the Steady State of the Internal Environment

External factors: changes in external environmental factors

Internal cause: The range of dynamic changes in the physical and chemical properties and chemical composition of the internal metabolic activity in the body. Body temperature: 36.5 ~ 37.5

Plasma pH: 7.35 ~ 7.45

High or low temperature, pH, etc. will affect the enzyme activity and cause cell metabolism disorders.

Malnutrition, lack of protein, obstructed lymphatic reflux, nephritis, etc. can cause tissue edema.

When sweating a lot, too much body fluid is lost, causing fatigue, hypotension, increased heart rate, cold limbs, and so on.

Urea, inorganic salts and other metabolic wastes accumulate too much in the body and uremia will occur.

Decreased levels of Ca and P in the blood can cause softening of bones in adults.

Triglycerides in the blood exceed the standard, leading to hyperlipidemia.
