How does food intake of protein enter the body?
In addition to the energy supplied, the protein in food is mainly used as raw material for body growth, renewal and repair.

Blood is pumped out of the heart by the arteries, delivered throughout the body and back through the veins to the heart. Therefore, in an upright human body, venous blood can overcome the effect of gravity and return from the lower limbs to the upper heart, which requires relying on the venous valve.
Whole body malnutrition with cancer, diabetes, tuberculosis and other chronic wasting disease, most of the body nutrition is poor, the body resistance is weak, thus affecting the wound healing.
Normal capillary pressure is 2 ~ 4kpa, the external pressure exceeds 4kpa, pressure duration of more than 2-4h, it will affect the local tissue microcirculation, limiting blood flow, causing soft tissue ischemia, resulting in Pressure ulcers.
During wound healing, M1 and M2 macrophages have significant differences in glucose, amino acids, and iron metabolism when they perform their different functions.
Fibroblasts proliferate largely through mitosis and synthesize and secrete large amounts of collagen fibers and matrix components from 4 to 5 days or 6 days to form granulation tissue together with nascent capillaries to fill wound tissue defects.
Due to paralysis of limb movement and sensory disturbances, local vascular neurotrophic poor, if the oppression for a long time, prone to bedsores.
The occurrence of mental and nutrition have a great relationship, usually refers to the nutritional problems of infancy, it will lay the hidden dangers of mental illness.
Continuous venous hypertension can cause local blood circulation and tissue absorption disorders, accumulation of metabolites, tissue malnutrition, lower extremity edema and skin nutrition changes, is the main cause of venous ulcers.
Microcirculation disorders, microvascular tumors and microvascular thickening of the basement membrane is a typical diabetic microangiopathy lesions.
