Blood and Lymph Basics
This system transports oxygen and carbon dioxide throughout the body.
What is the blood system?
This liquid medium makes up the fluid portion of blood in which solid components are suspended.
What is plasma?
These blood cells protect the body from pathogens, remove debris, and aid in healing.
What are white blood cells (leukocytes)?
These are the smallest formed elements in the blood and are actually fragments, not true cells
What are platelets (thrombocytes)?
This fluid, containing lymphocytes and monocytes, circulates through lymph vessels and is eventually returned to the blood.
What is lymph?
This function of blood prevents the body from losing too much blood after an injury.
What is clotting?
These are the three solid components of blood.
What are red blood cells, white blood cells, and platelets?
This process describes how WBCs move through capillary walls into tissue spaces.
What is diapedesis?
When a blood vessel is injured, platelets release this substance that begins the clotting process.
What is thromboplastin?
These small structures filter lymph, remove bacteria, and house T cells and B cells.
What are lymph nodes?
This system helps drain tissue fluid back into the bloodstream and delivers nutrients, hormones, and waste products.
What is the lymphatic system?
This process refers to the development of blood cells into their mature forms.
What is hematopoiesis (or hemopoiesis)?
White blood cells can ingest and destroy bacteria and foreign particles in a process called this.
What is phagocytosis?
This soluble blood protein is converted into fibrin strands during clot formation.
What is fibrinogen?
This organ resembles a lymph node, filters blood, destroys old red blood cells, and stores healthy blood cells.
What is the spleen?
In its simplest form, this system protects the body by using barriers to keep out unwanted substances.
What is the immune system?
These cells, also called erythrocytes, carry oxygen to the body’s tissues and remove carbon dioxide.
What are red blood cells?
Leukocytes that contain granules in their cytoplasm are called this type of WBC.
What are granulocytes?
This clear, watery fluid makes up about 92% water and serves as the transport medium for blood cells, nutrients, and waste.
What is plasma?
Lymph from the right chest and arm drains into this duct before returning to the bloodstream.
What is the right lymphatic duct?
The blood, lymphatic, and immune systems work together to maintain this stable internal condition in the body.
What is homeostasis?
During red blood cell development, the cell loses its nucleus and forms this iron-containing compound that gives blood its red color and carries oxygen.
What is hemoglobin?
Because of their deeply lobed nuclei, granulocytes—especially neutrophils—are also known by this alternative name.
What are polymorphonuclear leukocytes (PMNLs or polys)?
This blood type has A and B antigens on red blood cells and no antibodies in the plasma, making it the universal recipient.
What is type AB blood?
Located in the upper chest, this organ transforms certain lymphocytes into T cells to help regulate the immune system.
What is the thymus?
