Abstract:
We studied the relationship between the length and tension in isolated strips of the capsules of bovine mesenteric lymph nodes. The deformation-strain and radius-pressure relationships were established in the lymph node. The capsule possesses high distensibility, modulus of elasticity at optimal tension was 0.09×10(5) N/m2. Smooth muscle activation produces a 6-fold increase of modulus of elasticity. Maximum active stress in the capsule was recorded at a length of 1.1 L0 and maximal active pressure (4.5 cm H2O) at 0.9 L0.

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...
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.
Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
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...
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...
Fluid Connective Tissues: Blood and Lymph
Blood
The blood flows through blood vessels— arteries, capillaries, and veins. Blood plasma is primarily made of proteins, solutes, and water.
