The two main parts of the human circulatory system are the systemic circulation and the pulmonary circulation.
The circulation of the blood is a round trip system.
The lymphatic system of the body is a one-way system.
The three functions of the lymphatic system are:
a. Drain excess interstitial fluid
b. Transport dietary fats
c. Protect against pathogens and foreign substances
5. Body fluid found between cells of the body is called interstitial fluid.
6. Body fluid found within vessels of the body is called intravascular fluid.
7. Interstitial fluid drains back into the intravascular fluid through lymphatic vessels.
8. The thoracic duct drains into the left subclavian vein.
9. The right lymphatic duct drains into the right subclavian vein.
10. The name of the specialized lymphatic capillaries found in the vili of the small intestine is lacteals.
11. The specialty of these particular lymphatic capillaries is that they transport dietary fats.
12. The fluid these specialized lymphatic capillaries carry is called chyle.
13. The two primary lymphatic organs are the thymus and bone marrow.
14. The three secondary lymphatic organs are lymph nodes, spleen, and tonsils.
15. The "wastewater treatment plants" of the body are the lymph nodes.
16. The largest lymphatic organ of the body is the spleen.
What is the key to a healthy immune system? The key to a healthy immune system is balance.
Anything that can trigger an immune response is called an antigen.
What do lymphatic vessels carry? Lymphatic vessels carry lymph fluid.
Where do all immune cells come from? All immune cells come from stem cells in the bone marrow.
How do B cells chiefly work? B cells chiefly work by producing antibodies that recognize and neutralize pathogens.
True or False: Each B cell is programmed to make one specific antibody. True.
What cell in the body is essentially a factory for producing antibody? Plasma cells are essentially factories for producing antibodies.
List two major ways that T cells contribute to immune defenses:
a. Helper T cells help activate and coordinate the immune response.
b. Cytotoxic T cells directly kill infected cells.
What do we call large white cells that can swallow and digest microbes and other foreign particles? We call them phagocytes.
What do we call phagocytes that circulate in the blood? Phagocytes that circulate in the blood are called monocytes.
What do we call monocytes after they leave the blood and migrate into tissues? Monocytes that migrate into tissues are called macrophages.
What type of granulocyte uses its prepackaged chemical to break down the microbes it ingests? Neutrophils use their prepackaged chemicals to break down microbes.
What are the two granulocytes that can "degranulate" and spray their chemicals into harmful cells or microbes nearby? The two granulocytes that can degranulate are eosinophils and basophils.
What is the name of the system that is made up of about 25 proteins in the blood that work together to "complement" the action of antibodies in destroying bacteria? The system is called the complement system.
