The three main differences between lymphatics and veins are;
Definition
1. they have thinner walls 2. they contain more valves and 3. they contain lymph nodes lacted at certain intervals along their course
Term
What is the process by which extra cellular fluid flows into a target cell?
Definition
cytolysis
Term
the dense connective tissue that surrounds a lymphatic organ; has extensions (trabeculae) that penetrate inward and further divide the organ into smaller compartments
Definition
capsule
Term
a specific protein found on the plasma membranes of B and T cells that are able to recognize specific antigens
Definition
antigen receptor
Term
a specialized lymphatic capillary in the small intestine that carries dietary lipids to lymphatic vessels
Definition
lacteal
Term
a protein released by natural killer (NK) cells that creates channels in the plasma membrane of the target cell
Definition
perforin
Term
the tissue compatibility between a donor and recipient
Definition
histocompatibility
Term
An inner layer of an organ
Definition
medulla
Term
the cell- and antibody-mediated immune responses against transplanted organs

graft rejection
Term
the ability to provoke an immune response by stimulating the production of specific antibodies

Term
three purposes of the lymphatic system are;
