Which fluid does lymph most closely resemble?
Interstitial fluid
Lymph contains some protein.
true
Does Lymph contain several red blood cells?
false
The lymphatic system's two main functions are to assist in:
immunity and fluid balance
Like veins, lymphatic vessels rely on skeletal muscle and respiratory pumps to help propel fluid through them.
true
The force that drives fluid into lymphatic capillaries is:
hydrostatic pressure in the interstitial space.
The spleen is considered a primary lymphatic structure.
false
The walls of lymphatic capillaries are only one cell thick.
true
Which of the following contains red marrow?
Rib, sternum, flat bones of the skull, and vertebrae.
Which would be the route taken by lymph traveling from lymphatic vessels in the right leg to the bloodstream?
Right lumbar trunk - cisterna chyli - thoracic duct - left subclavian vein.
B-lymphocytes are:
white blood cells that are generated in red bone marrow.
MALT is found in which layer of the wall of a hollow organ?
Lamina propria
The thymus is at its maximum size:
puberty
Lymphatic nodules consist of:
lymphatic cells, extracellular matrix, and an incomplete connective tissue capsule.
Lymph nodes may be found individually, or clustered in specific regions of the body. Which cluster of lymph nodes receives lymph from the head and neck?
Cervical lymph nodes.
Lymph nodes are:
They are covered by a connective tissue capsule, They contain a network of lymphatic sinuses, Each node has an outer cortex and inner medulla, and Lymphatic nodules produce lymphocytes.
17.
Which lymphatic organ contains red pulp and white pulp?
spleen
What are functions of the spleen:
serves as a platelet reservoir, Filters blood, Recycles aged erythrocytes, and Houses lymphocytes.
The hilum of the spleen is part of its:
concave anteromedial border.
Which lymphatic system organ involutes and becomes nonfunctional as aging occurs?
Thymus
Trace the path of lymph from the time it leaves the interstitial spaces to the time it enters the blood:
1) Lymphatic capillaries, 2) Afferent lymphatic vessels, 3) Lymph nodes, 4) Efferent lymphatic vessels, 5) lymphatic trunks, 6) lymphatic ducts.
The formation of lymph increases as a result of:
increasing hydrostatic pressure in tissue fluid.
The primary functions of lymph include:
returning proteins to the bloodstream and transporting foreign particles to the lymph nodes.
Part of a lymph node? Compartments that contain masses of lymphocytes and macrophages, Afferent vessels circulating lymph into the node on its convex surface, Efferent vessels circulating lymph out of the node at its hilum, and lymph nodules.
yeah
In the spleen, white pulp contains large amounts of lymphocytes and macrophages while red pulp contains a large amount of erythrocytes, platelets, and some lymphocytes and macrophages.
true
The spleen contains the largest single store of a formed blood element, outside red bone marrow, called __________ .
platelets.
