lymphatic and immune system

3 functions of the lymphatic system

Drains excess interstitial fluids from body tissue and returns to circulatory system, transports, lipids, and fat soluble vitamins absorbed through intestines, immune response

Primary lymphatic organs

Red bone marrow and thymus

Secondary lymphatic organ

Lymph nodes, spleen, and lymphatic nodules

Lacteal

Specializes lymphatic capillaries in the small intestine

Parenchyma

Functional part of an organ

Antigen

Substance that elicits an immune response

Pathogen

Disease causing microorganism

Resistance

Words of diseases through defense

Stroma

Tissue that forms organ framework

Primary lymphatic organ

Area where immunocompetence occur

Secondary lymphatic organ

Area where WBCs battles pathogens

Dendritic cell

Captures antigens and presents them to the lymphocytes in the lymph nodes and elsewhere

B lymphocytes

Differentiate into plasma cells, which eliminate antigens using protein antibodies

T lymphocytes

Attacks and destroys infected cells

Macrophage

Gobble up foreign substances and activates T cells

Reticular cell

Secretes a fibrous connective tissue matrix that composes mostly lymphatic organs

Function of lymph node

Filters lymph, and site of B cell proliferation

Function of thymus

Site of T South immunocompetence

Function of red bone marrow

Site of B & T cell generation

Function of the spleen

Destruction of old red blood cells, immune response to blood-borne pathogens, and platelet and macrophage storage

Function of tonsils

Gathered and removed pathogens in food or air

Function of Peyer’s patches

The immune surveillance of pathogens entering digestive tract

Function of appendix

Stories bacteria before they can penetrate intestinal wall

What is immunocompetence?

The ability to effectively recognizing respond to and defend against pathogens and foreign substances

When the liquid component of blood plasma is forced out of capillaries, it becomes?

Interstitial fluid

Once it is transported into lymphatic capillaries it becomes

Lymph

This fluid then circulate through——-and is filtered by passing through———

Lymphatic vessel & lymph node

It eventually returns to Venus circulation via

Lymphatic duct

The majority of lymph is in the body is drained into Venus cyclization via the——- duct

Write lymphatic

What is nonspecific residence?

It’s present at birth, and it provides immediate but general protection against a wide range of pathogens

What are the external defenses in nonspecific residence?

Skin, mucous membrane, & digestive system

What are the internal defenses of nonspecific residence?

Antimicrobial protein, natural killer cells, and phagocytes

What is specific resistance?

It’s adaptive immunity, gives it the ability of the body to defend itself against specific pathogens

Interferons

Protein that interferes with viral replication

Complement

Enhances immune response

Transferrins

Protein which binds up raw materials needed for pathogen replication

Opsonization

Process of making foreign cells more tasty

Phagocyte

Cells which devour other cells

Haptens

Small molecule, which may be come antigenic when joined to body protein

Epitope

Reactive region of an antigen

Diapedesis

Passes by which white blood cells move out of capillaries

MHC1 antigen

Self marker present on all nucleated cells

MHC2 antigen

Self marker presented on APC

Costimulation

Process by which T cells are activated

Immunoglobulin

Glycoprotein antibody

How does inflammation aid the body in response to injury and potential infection?

Vasodilation and emigration a phagocyte

Given the antigen receptors are very specific how can the body detect and bind to antigens that it has never encountered before

Which type of immunity uses antibodies to engage free antigens that are floating around in body fluids tissue

What type of immunity uses cytotoxicity cells to engage, infected body cells?

function of helper T cells?

Recognizes foreign antigens associated with MHC 2 markers on APC

Function of regulatory T cells

Function of memory, T cells

Remains after cell media did immune response carries specificity to antigen, which previously caused disease

Function of cytotoxic, T cells

Kills target cells

What cell types are CD4?

Helper, T cells & regulatory T cells

What cell types are CD8?

Cytotoxic T cells

Which cell type is CD4 & CD8?

Memory T cells

A body cell is displayed MHC one marker bonded with viral protein. What does this indicate what will happen to the cell?

It will be destroyed

Function of B cells

Recognizing exogenous (free) antigens & participate in antibody mediate immune response(humoral)

Function of plasma cells

Produces antibodies which attack antigen directly

Function of memory cells

Create more plasma cells and memory B cells during secondary response

precipitation

agglutination

lysis

neutralization

Which is not an autoimmune disease

A mother was previously infected with a flu virus and temporarily passed it on humoral immunity to her child via transferred of colostrum during breast-feeding. This would be an example of——— immunity

A child is given a measles virus prior to going to elementary school, where they may encounter children with actual measles. This would be an example of——— immunity

ELISA

Adjuvant

Hybridoma

Reverse transcriptase inhibitor
