[The role of lymphatic collector in the spreading infections in peritonitis]
Abstract:
The article generalizes the result of experimental study of the features of hemolymphodynamics, toxic properties of biological body fluids, and microbiological findings in peritonitis. Experiments were conducted on 24 dogs. The development of the pyogenic process was visually studied. For this purpose the opened abdominal cavity was placed in a specially constructed transparent chamber in which a temperature of 37 /*C was maintained. Portal blood flow intensified and lymph production in the abdominal cavity reduced in the initial phase of peritonitis. Later lymph production increased while the portal blood flow decreased. The purulent process may develop according to two variants. In the first variant the functional activity of the liver is maintained and its toxic products and microorganisms are detoxified; the second variant the detoxification function of the liver is disturbed, the bacteria penetrate the peripheral blood, the production and flow of lymph in the thoracic duct increase sharply. The efficacy of external drainage of the duct and lymphosorption is much higher in the second variant of peritonitis development than in the first variant.

Functions of the Lymphatic and Immune System
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...
Lymphatic Vessels and Lymph Transport
This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular spaces.
Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
