What are the two functions of the lymphatic vessels? - Answer✔️✔️1) Return excess fluid
from intracellular space to blood circulation
2) anatomical seat of immune system
What is the correct order of lymphatic vessels that lymph travel from intracellular space back
to circulation? (Smallest to Largest) - Answer✔️✔️Lymphatic capillaries
Lymphatic collecting vessels
lymphatic trunks
lymphatic ducts
What type of tissue are lymphatic capillaries made of? - Answer✔️✔️Simple squamous
epithelium
Describe the lymphatic capillary structure - Answer✔️✔️Overlapped simple squamous cells
that form simple values to collect intracellular fluid
,What type of filament holds down lymphatic capillaries to the surrounding connective tissue -
Answer✔️✔️Collagen filaments
What force allows interstitial fluid to flow into the lymphatic vessels? - Answer✔️✔️A
difference in hydrostatic pressures between interstitial fluid and lymph in the capillary
What are lacteals? - Answer✔️✔️capillaries in intestinal mucosa that absorb lipid globules
to be metabolized by the liver
What is the fluid driving force to transport lymph in the collecting vessels? -
Answer✔️✔️skeletal and respiratory pumps
Lymphatic trunks drain which major body regions? - Answer✔️✔️Lumbar
Bronchomidiastinal
Subclavian
Jugular
Intestinal
Where does the Right lymphatic duct drain? - Answer✔️✔️Right side of the upper arm,
thorax and head (Thoracic duct gets the rest of the body)
,Which veins do the two ducts empty lymph back into blood circulation? -
Answer✔️✔️Jugular and Subclavian vein
What are the two classes of lymphoid cells? - Answer✔️✔️T lymphocytes
B lymphocytes
What type of tissue is diffuse lymphoid tissue made of? - Answer✔️✔️Reticular connective
tissue
Where is diffuse lymphoid tissue located? - Answer✔️✔️lamina propria of the mucous
membrane
What is the structure of lymphoid follicles? - Answer✔️✔️spherical collections of diffuse
lymphoid tissue with in a fibrous capsule arranged around a germinal center containing
dendritic cells and B lymphocytes
What are lymph nodes? - Answer✔️✔️Packets of lymphoid follicles that house lymphocytes
and macrophages that filter lymph to initiate the immune response
, What makes up the cortex of lymph nodes? - Answer✔️✔️follicles housing B lymphocytes
What makes up the medulla? - Answer✔️✔️reticular connective tissue that allows sinus of
lymph to be filtered housing T lymphocytes
Why are there more afferent vessels than efferent vessels? - Answer✔️✔️slow down the
flow of lymph to allow enough time for immune cells to initiate their response
What are the two functions of the spleen? - Answer✔️✔️1) lymphocyte proliferation
2) Erythrocyte recycling
What are the differences between white pulp and red pulp? - Answer✔️✔️White pulp -
made up of lymphocytes in reticular tissue
Red pulp - venous sinus with high concentration of red blood cells
What is the structure that forms inward capsules that extend inward into the medulla of the
spleen that stores platelets and broken down erythrocytes? - Answer✔️✔️Trabeculae
What structure is responsible for secretion of hormones that causes T-cells to be
immunocompetent? - Answer✔️✔️Thymus
