Edapt week 4- lymph and lymphatic vessels
The formation of lymph increases as a result of _______: -increasing osmotic pressure in blood capillaries -decreasing volume of tissue fluid. -increasing hydrostatic pressure in tissue fluid -decreasing protein concentration in tissue fluid -increasing the number of white blood cells that leave the blood for the lymph.
increasing hydrostatic pressure in tissue fluid (Lymphatic capillaries receive the fluids to generate lymph whenever the pressure of the tissues (hydrostatic) is higher than the pressure within the lymph capillaries)
Place the following steps of lymphatic flow in the correct order beginning with the interstitial fluid and ending with the blood vessels: -Lymphatic capillary -Afferent lymphatic vessel -Lymph node -Efferent lymphatic vessel -Lymphatic trunk -Collecting duct -Subclavian vein
-Lymphatic capillary -Afferent lymphatic vessel -Lymph node -Efferent lymphatic vessel -Lymphatic trunk -Collecting duct -Subclavian vein (The correct flow of lymph is from the interstitial fluid into the capillaries which merge to form the lymphatic vessels, then the trunks, then the ducts, and finally the lymph is drained into the subclavian veins. Where nodes are found, lymph enters via afferent vessels and leaves via efferent vessels)
Which of the following is NOT true of capillaries? -Capillaries have a tapered off end before reaching the vein -Some capillaries are capable of bulk flow transport -Capillaries are microscopic vessels -Capillaries consist of only one layer of epithelial tissue -Continuous capillaries function in the transport of gases
Capillaries have a tapered off end before reaching the vein (Capillaries are continuous with the arteries and veins, lacking a terminal tapered end)
Lymphatic capillaries are found in all the following tissues or areas EXCEPT the _______: -blood capillary networks -areolar connective tissue -the digestive tract -epithelial tissues -jugular regions
Epithelial tissues (Neither lymphatic vessels nor blood vessels penetrate through the epithelial tissues)
______ fluid refers to ANY extracellular fluid that is not found in blood fill in the blank
Interstitial (Interstitial fluid is the extracellular fluid outside of blood vessels. The fluid of the blood is known as plasma)
Place the following steps of lymphatic flow in the correct order beginning with the interstitial fluid and ending with the blood vessels Interstitial fluid Lymph capillaries Lymph vessels Lymph trunks Lymph ducts Subclavian veins
Interstitial fluid Lymph capillaries Lymph vessels Lymph trunks Lymph ducts Subclavian veins (The correct flow of lymph is from the interstitial fluid into the capillaries which merge to form the lymphatic vessels, then the trunks, then the ducts, and finally the lymph is drained into the subclavian veins)
Lymph from the head and neck drains into the left and right _______ trunks: -bronchomediastinal -subclavian -lumbar -intestinal -jugular
Jugular (The jugular trunk is the vessel that can receive lymph from the head and neck)
The right lymphatic duct receives lymph from all of the following body regions EXCEPT the _______: -head -lower limbs -right-upper limb -thorax
Lower limbs (The left lymphatic duct (thoracic duct) is responsible for receiving lymph from both lower limbs)
What is the major component of blood plasma? -Thrombocytes -Water -Albumin -Fibrinogen -Erythrocytes
water (Water makes up approximately 90% blood plasma)
