lymphatic ducts

IDENTIFICATION

this structure connects lymphatic trunks to large veins

right lymphatic duct

IDENTIFICATION

this is where Jugular, subclavian, and bronchomediastinal trunks often connect separately and drain lymph from the right side of the head, right arm, and right chest

thoracic duct

IDENTIFICATION

largest lymphatic vessel that drains lymph from the right side of the body inferior to the thorax & the entire left side of the body

cisterna chyli

an enlarged pouch on the thoracic duct that serves as a storage area for lymph moving toward its point of entry into the venous system; sac that is formed by the lymphatic trunks

lymphocytes, reticular fibers

FILL IN THE BLANKS

lymphatic organs contain lymphatic tissues which consists of ______ and ______

lymphocytes

IDENTIFICATION

Part of the immune response that destroys microorganisms and foreign substances and originates from the red bone marrow

reticular fibers

IDENTIFICATION

produced by the reticular cell, this traps microorganisms and other particles; filters fluid

connective tissue capsule

FILL IN THE BLANK

Lymphatic tissue of the body may or may not be separated from other tissues by a ______ ______ ______

mucosa-associated lymphoid tissue

IDENTIFICATION

a group of nonencapsulated lymphatic tissues found in and just below the mucous membranes; it catch and stop harmful microorganisms as they try to enter the body through these systems

lymphatic nodules

IDENTIFICATION

found within lymph nodes and the spleen, this is a denser arrangement of lymphatic tissue and is usually referred to as lymphatic follicles

peyer patches

IDENTIFICATION

a group of lymphatic nodules in the distal half of the small intestine

tonsils

IDENTIFICATION

large groups of lymphatic nodules and diffuse lymphatic tissue that protects against bacteria and other potentially harmful material entering the pharynx from the nasal or oral cavity

palatine tonsil

IDENTIFICATION

type of tonsils

relatively large, oval, lymphatic masses on each side of the junction between the oral cavity and the pharynx

pharyngeal tonsils

IDENTIFICATION

type of tonsils

collection of somewhat closely aggregated lymphatic nodules near the junction between the nasal cavity and the pharynx

adenoids

IDENTIFICATION

enlarged pharyngeal tonsil which interferes with normal breathing

lingual tonsils

IDENTIFICATION

type of tonsils

loosely associated collection of lymphatic nodules on the posterior surface of the tongue

TRUE

TRUE OR FALSE

In adults, the tonsils decrease in size and eventually may disappear

1 multiple choice option

lingual

FILL IN THE BLANK

______ tonsils become infected less often than the other tonsils and are more difficult to remove

lymph nodes

IDENTIFICATION

distributed along the course of the lymphatic vessels; this filter the lymph, removing bacteria and other materials

450

Approximately there are how many lymph nodes found in the body?

dafuq

INFORMATION

type "dafuq" when answring

number of lymph nodes

capsule

IDENTIFICATION

structures in the lymph nodes

surrounds each lymph node

trabeculae

IDENTIFICATION

structures in the lymph nodes

extensions of the capsule; form the internal skeleton of the lymph node

reticular fibers

IDENTIFICATION

structures in the lymph nodes

extend from the capsule and trabeculae; from a fibrous network throughout the lymph node

lymphocytes & macrophages

IDENTIFICATION

structures in the lymph nodes

Packed around the reticular fibers; Form lymphatic tissue

lymphatic sinuses

IDENTIFICATION

structures in the lymph nodes

open spaces

outer cortex

IDENTIFICATION

layers of the lymph node

this layer contains the Subcapsular Sinus and Cortical Sinuses

inner medulla

IDENTIFICATION

layers of the lymph node

this layer contains the Medullary Cords and Medullary Sinuses

lymph nodes

IDENTIFICATION

these are the only structures that filter lymph

afferent lymph nodes

IDENTIFICATION

type of lymphatic vessel that carry lymph to the lymph nodes

efferent lymph nodes

IDENTIFICATION

type of lymphatic vessel that carry lymph away from the lymph node

spleen

IDENTIFICATION

located on the left, superior part of the abdominal cavity; this structure destroys defective red blood cells, dects and responds to foreign substances in the blood, and acts as a blood reservoir
