functions of the vessels and lymphatic system

Lymphatic vessels have a one-way flow from the extremities to the heart. Damage to the lymphatic system can lead to edema, an increase in tissue fluid. From the standpoint of reducing edema, how does the use of medical leeches (segmented worms that drain tissue fluid) work for a region that has suffered trauma?

Get rid of excess fluid and prevent swelling.

Superficial veins contain valves. Inactive people may have problems with their veins in the blood pools in the veins. Can you propose a mechanism by which blood from the veins may be returned to the heart (other than standing on your head!)?

Person should be more active. compression socks. ,

what is the name of the inner region and outer region of lymph node ? describe their function

inner region is the medulla , and the outter region is the cortex filter lymph and destroy bacteria and immune system.

once tissue fluid enters the lymphatic vessels ,what is it called ? what might be found in this fluid?

it is called lymphatic fluid

what tonsils are located at the back of the tounge ?

lingual tonsils

from what yu know of the functions of the lymph node ,makes prediction pf the difference between lymph entering a node and lymph leaving a node. what materials may be missing from the lymph leaving the node ?

lymph entering would be full of bacteria and lymph leaving would be filtered

which tonsils are found on the sides of the oral cavity

palatine tonsils

the adenoids are enlarged ______ tonsils

pharyngeal

what functional advantage does this tissue type provide to the capillary ?

A simple squamous epithelium enables capillaries to allow small molecules such ah nutirents to pass from blood into the body. waste products and oxygen are also exchanged way.

name the vessel that takes lymph to a lymph node and vessel that takes lymph away from a lymph node

afferent and efferent

trace the flow of the lymph system from the region of the lymph capillaries to the subcalvain veins

blood capillaries ,intersital spaces (intersital fluid) lymphatic capillaries (lymph), lymphatic vessels (lymph), lymphatic ducts (lymph),inteernal jugular and subclaivian vein junction (blood)

in the analysis of the breast cancer ,lymph nodes of the axillary region are removed and biophys is performed. the removal of the nodes is nodes is done determine if its cancer has spread from the breast to other region of the body. what effect would the removal of lymph nodes have on the drainage of the pectoral region ?

decrease amount of drainage ,lead to edema swelling of pectral region

what type of the tissue makes up the endothelium of capillaries /

single layer f the simple squamous layer

blood is recycled by which lymph organ in the adult

spleen

where do the T cells become immunocompetent

thymus

what part of the spleen is involved in the storage of monocytes

white pulp
