Exam 2

anti-microbial substances promote cytolysis, phagocytosis and inflammation

most important in forcing blood flow through veins

B cell receptors, the light/heavy variable regions are located

when an artery or arteriole is damaged, its smooth muscle contracts producing

Capillaries are also known as

not found in arteries but is found in veins

self-responsive cell that is inactive

volume of blood that flows through any tissue in a given time period

blood vessel that distributes blood to organs

this depends mostly on the ratio of RBC to plasma volume

the most variable cell in the immune system

would not increase blood pressure

does not provide a physical or chemical barrier

blood vessel that conveys blood from the tissues back to the heart

When B and T cells are fully developed and mature, they are known to be

which artery wall is responsible for vasoconstriction

Lack of resistance is also known as

pressure driven movement of fluids and solutes from blood into interstitial fluid is called

alternate route of blood flow to a body part through an anastomosis is called

these vessels make up the largest blood reservoir

type of shock is due to decreased blood volume

part of the body's second line of defense

this can only become activated when bound to a foreign antigen and simultaneously receiving a costimulate

not a sign of inflammation

natural exposure to an infectious agent leads to

small hormone that can stimulate or inhabit many normal cell function

most important capillary exchange method

primary response will peak how many days after an exposure

vessels supplies blood to the intestines

type of immunity defends against any type of invader

pulse cannot be felt

largest factor that promotes reabsorption of fluids, into blood, from the interstitial fluids is

cardiovascular center is located

produces the hormone that promotes maturation of T cells

Not considered an organ of immune system

vessels supplies blood to the kidney

class of ells include macrophages, b cells, and dendric cells

lymphocytes can recognize

T Cells secrete this toxin that is used to fragment DNA

Blood flow depends on which of the following

not a function of the lymphatic and immune system

all the veins of the systemic circulation drain into the

an acute allergic response can lead to

in fetal circulation what is the opening between the right and left atria called

ability of an antigen to react specifically with the antibodies or cells it has provoked

skeletal muscle and respiratory pumps are used in

class of antibodies mainly found in sweat, tears, breast milk, and GI secretions

class of antibodies indicates a most recent invasion

Layer of the artery is composed mainly of elastic and collagen fibers

vessel plays a key role in regulating blood flow into capillaries

what hormone would not cause an increase in blood pressure

induces production of a specific antibody

these anti-microbial substances will diffuse to uninfected cells and reduce production

below vessels drains blood from the head and neck

characterized by the inability of the immune system to protect the body from a pathogen

pulse point at the wrist

can only stimulate an immune response if attached to a large carrier molecule

major difference between lymph and interstitial fluid

elastic arteries function
