Microbial antagonism
Normal microbiota competing with potential pathogens
Normal microbiota activities that make it hard for pathogens to compete against
Consumption of nutrients, and creating an environment that makes it unfavorable to other microorganisms that pathogens cannot grow in
Vitamins

Blood
Liquid tissue composed of cells and cell fragments within a proteinaceous liquid called plasma
Plasma
Has hella proteins in it Blood minus the cells; includes proteins involved in inflammation, clotting, iron binding, complement, adaptive immunity (antibodies)
Antibodies
Protective molecules
Serum
Plasma without the clotting factors Minerals, salts, proteins, and other organic molecules
Erythrocytes
Red blood cells
Buffy Coat
White blood cells + platelets (clotting): Thrombocytes
Stem cells
The beginning of making many types of blood cells
Erythroid stem cells
No nucleus O2+ CO2
Platelets
Clotting, inflammation
Basophil
Allergies
Eosinophil
Eliminates helmiths + protzoans
Monocyte
Blood
Lymphocyte
Adaptive response, natural killer cells • B cells + T cells
Neutrophils
Most numerous
CBC
Complete blood count (overall health)
What do increased eosinophils indicate?
Parasitic worm infection/ protozoan/ helmith
What does an increase in leukocytes and neutrophils indicate?
Bacterial Diseases
What does an increase in lymphocytes indicate?
Viral infections
