Leukocytes comprise:
1) Lymphocytes
B cells, helper T cells, cytotoxic T cells, memory cells
antibody production, immune activators, cell killer, secondary response
2) Eosinophils
anti-parasites
3) Neutrophils
neutralises bacteria and fungi
4) Basophils
release histamines for allergic inflammatory responses
5) Monocytes
Macrophages, antigen-presenting cells
6) Dendritic cells
Antigen-presenting cells
Yes. Leukocytes are white blood cells.
Neutrophil
Lymphocyte
yes
when it gets past the first line (the skin)
Your body's third line of defense is the specific defenses, these defenses are called the immune response.
If there were to be an infection in this area, it is possible that you would not receive chemical input from the environment. And for the second portion of your homework... Olfactory cells, olfactory nerve, and olfactory bulb :)
a weaker/dead form of the pathogen is introduced to allow the body to produce the correct antibodies and make a memory-B cell that stimulates a faster immune response if the same pathogen is encountered a second time, preventing a full scale infection and making you "immune" to that pathogen
The integumentary system is one of the first lines of defense against infection. It provides a physical and chemical barrier against the entry of pathogens.
the body's second line of defense against pathogens is the B cells.
yes
The Second Line of defense is mainly called the Inflammatory Response. Some may say the immune response is the second layer too. The Second Line of Defense also includes leukocytes such as macrophages.

phagocytes
the body's second line of defense against pathogens is the B cells.
the most comon leukocyte in peripheral blood is neutrophils
Nobody, but Amycus Carrow becomes teacher of Dark Arts.
Your skin,sweat,mucus,and tears is the first line of defense of your immune system. it is the original protector from bacteria and viruses
Well, you first get infected from a scratch or bite, then the infection spreads into the bloodstream, getting by the first line of defence. The second line of defence, would be the white blood cells. They try overcome or "swallow" the infection. the third line of defense, is the anitgens. If all else fails, your f*cked.
The integumentary system (skin) and mucous membranes are the first line of defense. They provide a physical barrier against invasion of pathogens. Any break in this physical barrier, such as a cut, makes it easier for pathogens to enter your body.
