Lymphatic System Basics
This organ is considered the primary organ of the lymphatic system.
What is the lymph node?
This liquid component of blood carries oxygen and nutrients to cells and removes waste products.
What is plasma?
This blood type is known as the universal donor.
What is O negative?
This condition is characterized by an abnormal increase in white blood cells, often indicating an infection.
What is leukocytosis?
True or False: The spleen is considered part of the lymphatic system.
What is True?
These small, bean-shaped structures are found throughout the lymphatic system and filter lymph fluid.
What are lymph nodes?
These blood cells are responsible for carrying oxygen throughout the body.
What are red blood cells?
Blood type is determined by the presence or absence of these molecules on the surface of red blood cells.
What are antigens (specifically A and B antigens)?
What is the name of the condition where there is an inadequate number of red blood cells or hemoglobin in the blood?
What is anemia?
What is the name of the large lymphatic organ located in the chest, above the heart?
What is the thymus gland?
The lymphatic system plays a key role in this bodily function, which involves the removal of waste and toxins.
What is immune function?
What is the name of the process by which blood cells are formed?
What is hematopoiesis?
People with this blood type are considered universal recipients.
What is AB positive?
This autoimmune disease causes the body to attack its own red blood cells.
What is autoimmune hemolytic anemia?
This term refers to the process by which white blood cells engulf and digest foreign particles or cells.
What is phagocytosis?
True or False: Lymphatic vessels have a pump (like the heart) to circulate lymph fluid.
What is False? (Lymphatic vessels rely on skeletal muscle contractions and breathing to circulate lymph fluid.)
These cells are responsible for the clotting process, preventing excessive bleeding when you are injured.
What are platelets?
True or False: AB+ is the rarest blood type.
What is False? (AB+ is one of the rarest, but AB- is slightly rarer.)
What is the term for a blood clot that forms inside a blood vessel?
What is a thrombus?
These small, round structures are found throughout the body and act as checkpoints for the immune system.
What are lymphoid nodules (or lymphoid follicles)?
Name one major function of the lymphatic system.
What is filtering lymph, fighting infection, or transporting fats?
Name one type of white blood cell and its primary function.
Examples include neutrophils (phagocytosis), lymphocytes (immune response), monocytes (phagocytosis), eosinophils (parasitic infection defense), and basophils (allergic responses).
in addition to the ABO blood group system, blood is also categorized by this other system, which involves the presence or absence of a different antigen on red blood cells.
What is the Rh factor (Rh-positive or Rh-negative)?
This genetic disorder results in the production of abnormal hemoglobin, causing red blood cells to become rigid and misshapen.
What is sickle cell anemia?
Name one major blood vessel that carries oxygenated blood away from the heart.
Examples include the aorta, pulmonary artery, or any artery leaving the heart.
