Tox/o
Clear, watery fluid that surrounds body cells and flows in a system of thin-walled lymph vessels that extends throughout the body. It is rich in two types of white blood cells: lymphocytes and monocytes.
Lymph
Thin-walled tubes that begin at the spaces around cells throughout the body. These tubes carry lymph from the tissue spaces to larger lymph vessels.
Lymph Capillaries
Nodes in the neck.
Cervical Nodes
Spleen

What are the two major disease-fighting lymphocytes, and what are their functions?
B Lymphocytes (B Cells): produce antibodies
T Lymphocytes (T Cells): attack bacteria and foreign cells by accurately recognizing a cell surface protein as foreign, attaching to the foreign or cancerous cells, poking holes in them, and injecting them with toxic chemicals.
This organ is located beneath the left side of the diaphragm and behind the upper part of the stomach. It stores new red blood cells and destroys old red blood cells.

Located in the center of the upper chest. It is important in the development of an effective immune system and used to resist disease during childhood.

What are leukocytes, and what do they do? Give three examples.
AKA White Blood Cells (WBCs). They protect the body against both infectious disease and foreign invaders. Examples: Neutrophils, Monocytes, Lymphocytes, Granulocytes, and Macrophages.
Thicker-walled tubes that contain valves so that lymph flows in only one direction, toward the thoracic duct.
Lymph Vessels

What are the different types of T-Cells, and what are their functions?
Cytotoxic T Cells (CD8+ cell or T8 cell): attach to antigens and kills offending organism. Also produce proteins called cytokines that aid other cells in antigen destruction.
Helper T Cells (CD4+ cell or T4 cell): promote the responses of B Cells and other T Cells to neutralize antigens
Suppressor T Cells (Treg): control B Cell and T Cell activity and stop the immune response when an antigen has been destroyed.
The ________ ____ drains the lower body and the left side of the head, whereas the _____ _________ ____ drains the right side of the head and chest.
Thoracic Duct; Right Lymphatic Duct
Nodes between the lungs in the chest.
