A-B

substance with a pH less than 7

protection against a specific pathogen resulting from the production of antibodies in response to the presence of specific antigens (ex. infection or vaccine)

develops specific response triggered by presence of specific antigens. because each is unique, adaptive immunity is at a slower rate. once defense is creates, cellular memory is able to trigger a faster response

a gland above the kidney that produces hormones to regulate heart rate, blood pressure, and other functions

a hormone secreted by the adrenal gland that increases reabsorption of sodium ions

an immune response to a foreign agent that is not a pathogen

tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place

monomers that make up proteins

standard positioning of the body as standing, feet together, arms to wide, head eyes and palms face forward

a secretion that acts to restore blood volume and blood pressure by constricting blood vessels, stimulating thirst, and stimulating production of aldosterone and antidiuretic hormone

negatively charged ion

blood protein that counteracts as a specific antigen

a defense that employs B cells to create antibodies that tag pathogens for later destruction. AKA HUMORAL IMMUNITY

secretion from the pituitary gland that increases the amount of water able to be reabsorbed from a collecting duct

cell (such as macrophages, dendritic cells, B cells) that consume a pathogen, and then put parts of ingested antigen on its cell membrane to alert patrolling T cells

substances on the surfaces of agents that act to identify them, to the body, as being native or foreign

substance that kills or inhibits growth of microorganisms with minimal damage to the hosts

opening of the rectum from which solid wast is expelled

accessory structures of the dermis that are in physical association with hair follicles, producing a secretion with an odor

portion of the skeleton made up of our appendages- bones of arms, legs, hands, feet

vessels that carry blood away from the heart towards other parts

lung disease characterized by inflames, narrows airways and difficulty breathing

the most basic complete unit of an element

pathology that results from the immune system mistaking part of the body as a pathogen
