Lymphatic System
This category is for questions about the various vessels by which lymph, a watery fluid of leukocytes, circulates through the body, providing transportation for some materials and removing particulate from tissues.

How do phagocytes protect the body?
Phagocytes are a type of white blood cell. A phagocyte flows around bacteria, and sort of creates and dent in itself, which the bacteria goes into, and then the phagocyte closes around it, trapping the bacteria. Then the phagocyte secretes enzmes onto the bacteria to digest it.
What is the shortened form for the injection just below the skin?
It's called Sub-Q (short for subcutaneous).
What lymph vessel structures keeps the lymph flow going in one direction?
there are valves in the vessels that prevents backflow, just like in the viens
What does lymph transport depend on to function?
Lymph transport depends on the movement of adjacent tissues, such as skeletal muscles.
Describe the major difference between invertebrate and vertebrate immune systems?
1. Immunological memory:- present in vertebrates but absent in invertebrates.
2. Vertebrates have complement system but invertebrates have prophenoloxidase system
3. Vertebrates have lymphocytes but invertebrates have lectins
4. Antibody present in vertebrates and nit in invertebrates
Erythrocytes are larger than leukocytes. Erythrocytes have no nucleus while leukocytes have nucleus. Leukocytes remove and/ or destroys things that are considered "abnormal" in the body while erythrocytes carry oxygen to all body cells. Leukocytes are large round cells that do not contain hemoglobin while erythrocytes contain hemoglobin, are shaped as biconcave disks that bend, flex travel through narrow blood vessels and have a large surface to volume ratio.
Erythrocytes and leukocytes are both classified as formed elements (lower layer). They both are main components of the body are necessary for the body to function properly.

The percentage of Lymphocytes circulating in the blood.
What exactly would they be looking for when checking for this test?
What are the principle cells of the immune system and what is their role in the immune response?
The principle cells of your immune system are lymphocytes, or white blood cells. The immune system, however, is highly complex, and it is difficult to single out one type of cell for importance. All of the components have to work together in harmony for optimized function.
An immune response is generated when you are exposed to a foreign pathogen. Examples of this would be a virus, bacteria, parasite, or fungus. Your immune system's job is to recognize the invader and destroy it. In this case, the lymphocytes, or white blood cells, engulf the pathogen and eat it up, keeping it from multiplying and making you sick.
You want as many of these white blood cells as you can get when you are fighting off an infection. The rate limiting factor in the production of lymphocytes and the strength of your immune system is a protein called glutathione.
What are edges and lines nodes?
In graph theory, nodes (or vertices) are the fundamental units that represent entities in a network, while edges (or lines) are the connections between these nodes. Each edge connects two nodes, illustrating the relationship or interaction between them. For example, in a social network, nodes could represent individuals and edges could represent friendships. Together, they form a structure that can be analyzed to understand various properties and dynamics of the network.
