Which of the following is a true statement regarding the lymphatic system? A) It transports oxygen B) It absorbs dietary fats C) It produces red blood cells D) It maintains fluid balance
B) It absorbs dietary fats, D) It maintains fluid balance Which fluid does lymph most closely resemble?
Lymph most closely resembles interstitial fluid. The lymphatic system is responsible for which of the following functions in the body? A) Oxygen transport B) Fluid balance C) Immunity D) Fat absorption
B) Fluid balance, C) Immunity, D) Fat absorption Which of the following is a lymphatic organ? A) Heart B) Liver C) Spleen D) Kidney
C) Spleen Which of the following materials are not transported by lymphatic fluid? A) Lipids B) Oxygen C) White blood cells D) Proteins
B) Oxygen Which of the following is a characteristic of lymphangitis?
Lymphangitis is characterized by inflammation of the lymphatic vessels. What do lacteals do?
Lacteals are specialized lymphatic capillaries that absorb dietary fats and lipid-soluble vitamins in the small intestine. Which lymphatic organ cleans cellular debris and bacteria out of the blood?
The spleen cleans cellular debris and bacteria out of the blood. What is the function of lacteals?
Lacteals absorb dietary fats and lipid-soluble vitamins in the small intestine. Which statement regarding the lymphatic system is true? A) It transports oxygen B) It absorbs dietary fats C) It produces red blood cells D) It maintains fluid balance
B) It absorbs dietary fats, D) It maintains fluid balance How do lymphatic capillaries differ from blood capillaries?
Lymphatic capillaries are more permeable than blood capillaries and can absorb larger molecules like fats. Which of the following is a feature of the lymphatic system? A) It transports oxygen B) It absorbs dietary fats C) It produces red blood cells D) It maintains fluid balance
B) It absorbs dietary fats, D) It maintains fluid balance Which of these carries excess cholesterol from body cells to the liver?
High-density lipoproteins (HDL) carry excess cholesterol from body cells to the liver. What are the main components of the lymphatic system?
The main components of the lymphatic system are lymph, lymphatic vessels, and lymphoid tissues and organs. What is lymph, and how does it differ from interstitial fluid?
Lymph is the clear fluid formed when interstitial fluid enters lymphatic vessels; it differs from interstitial fluid mainly by its location. List the major lymphoid organs and tissues in the lymphatic system.
Major lymphoid organs and tissues include lymph nodes, bone marrow, thymus, spleen, tonsils, and mucosal associated lymphoid tissues (MALT). What role does the lymphatic system play in immunity?
The lymphatic system aids immunity by producing, maintaining, and distributing lymphocytes (B cells and T cells) that help defend against pathogens. Why can't large macromolecules like dietary fats enter blood capillaries directly?
Large macromolecules like dietary fats cannot enter blood capillaries directly because the capillary walls are not permeable to such large substances. What happens to interstitial fluid that is not reabsorbed by blood capillaries?
Interstitial fluid not reabsorbed by blood capillaries enters lymphatic vessels, becoming lymph, which is then returned to the bloodstream. What is the significance of returning leaked proteins to the cardiovascular system?
Returning leaked proteins to the cardiovascular system prevents tissue swelling (edema) and maintains proper blood volume and pressure.
