lympthatic system

Mononucleosis

Known as the "kissing disease," caused by the Epstein-Barr virus
* fatigue, fever, enlarged lymph nodes or spleen

Tonsillitis

Can be viral or bacterial; is an inflammation of infection of the tonsils
* throat pain, dysphagia, white spots, swelling of lymph nodes

Hodgkin's Lymphoma

A chronic, malignant disease of the lymph nodes. Is the most common lymphoma
* painless swelling of lymph nodes

Lymphedema

Swelling in an arm or leg caused by a blockage or damage to lymphatic vessels

Adenitis

Inflammation or infection of the lymph nodes

AIDS

This virus attacks the body's immune system, making it unable to fight off certain infections and diseases

Active Immunity

Protect from a specific disease by exposure to the infection.

Can be by having the disease or a vaccine

Immunity

Ability to resist infection

Lymphatic System

Works with the immune/circulatory system to remove waste and excess fluid from the tissues

Spleen

Organ that produces leukocytes and antibodies, destroys old erythrocytes, and filters wastes from body tissues

lymph nodes

Commonly known as "glands", these small masses filter Lymph and add antibodies to purify the lymph before returning it back into circulation

lymphatic vessels

Vessels that are located throughout the body in almost all tissue that has blood vessels

lymphatic capillaries

Small open-ended lymph vessels that pick up lymph throughout the body

lymph

When thin, watery interstitial fluid enters the lymphatic system

lacteals

Specialized lymphatic capillaries that pick up digested fats in the small intestine, mix it with lymph to form chyle, and returns it to the bloodstream

Innate Defense

nonspecific- what we’re born with
ex: skin, nails, hair, anything physical on body, mucinous, gastric juices, vaginal, fluid and fever

Aqquired Defense

we develop this when we are exposed to pathogens so our body create antibodies

lymphocytes (WBCs) help us fight infections

T cells-mature in thymus, signal help from b cell, kill invaders

B cells

produce specific antibodies to fight pathogens

active immunity

occurs from exposure to infections (ex: disease, illness, or vaccines)

passive

occurs when give the antibodies
(ex: mother to newborn oe immunoglobulin

metastasis

Spread of cancer from place from where they first form to another part of the body (travel through lymphatic system)

Cisterna Chyli

enclosed pouch like structure located at start of thoracic dict. Storage area for purified lymphs

Lacteals

specialized capillaries that pick up digested fats, form a milky fluid called chyle, tansport chyle toward the bloodstream, and chyle eventually enters the blood through the thoracic duct

Macrophage

type of white blood cell that uses phagocytosis to destroy pathogens

Antigen

A marker on a pathogen that tells your body it is foreign

Antibody

A protein made by B-cells that fights specific pathogens

lymphangitis

inflammation of lymphatic vessels- pathogen enters the vessel
* red streaks up the body part

thymus

lymphatic vessels

spleen

thoracic duct

right lymphatic duct

cervical lymph nodes

pharyngeal (adenoid) tonsils

palatine tonsil

lingual tonsils

Tonsils

Help protect against germs entering through the mouth and nose.

Thymus

Located in the center of the upper chest.

Helps develop the immune system.

Helps T-cells mature.

Shrinks after puberty and gets replaced with fatty tissue
