Left subclavian trunk Right broncho-mediastinal trunk Left lumbar trunk Right jugular trunk - answerC The tributary region of the RIGHT AXILLARY nodes is: Right and left mammary glands and upper extremities Right mammary gland, right upper trunk quadrant, right upper extremity Right mammary gland, right upper extremity, right side of head and neck Right mammary gland, right upper and lower trunk quadrant - answerB Which of the following is true about the thoracic duct? It is the largest lymphatic vessel in the human body It enters into the left venous angle All are true It starts at the cisterna chyli - answerC The functions of the lymphatic system include all of the following EXCEPT? Produce and store lymphocytes Absorb nutritional fatty acids from the intestines Return deoxygenated blood to the heart Absorb interstitial fluid and return it to the venous circulation - answerC Which of the following IS NOT a characteristic of lymph collectors? A three layer muscular wall Lymphangia Anchoring filaments Intrinsic contractility - answerC Which of the following lymphatic watersheds (WS) exist on both the anterior and posterior aspects of the body? Chaps Watershed Median-sagittal Watershed Spine of scapula Watershed Clavicle Watershed - answerB Which of the following is true about the intestinal lymphatic system? Intestinal lymph is called chyle The intestinal lymph sometimes appears white after a high protein meal The intestinal lymph is unable to carry proteins Water soluble vitamins are absorbed into the intestinal lymphatic system - answerA Which of the following statements regarding lymph and blood capillaries is true? Lymph capillaries have a smaller diameter than blood capillaries Blood capillaries have anchoring filaments and lymph capillaries do not A lack of a basement membrane in blood capillaries allows absorption of large protein molecules "Swinging flaps" of lymph capillaries allow absorption of large protein molecules - answerD Which of the following statements about lymph collectors is FALSE? Collectors connect with each other via anastamoses Deep collectors typically run along with arteries and veins Superficial collectors drain muscles, joints and ligaments Perforating vessels connect superficial to deep collectors through the muscle fascia - answerC Lymph fluid consists of which of the following? Proteins, red blood cells, lymphocytes, bile Proteins, water, insulin, white blood cells Fatty acids, cells, water, protein molecules Waste products, water, cholesterol, glucose - answerC The thoracic duct drains all of the following EXCEPT? The intestines, genitourinary organs, and liver The right arm and right trunk quadrant The right leg, left arm, and left side of the head and neck The left leg, both lower trunk quadrants, and both kidneys - answerB Which of the following statement about the lymph nodes is true? The majority of lymph nodes are found in the extremities Lymph nodes have more efferent than afferent lymph vessels There are 600-700 lymph nodes in the human body Lymph nodes are always palpable - answerC Which lymph vessel DOES NOT contain valves? Lymph collectors of the upper medial arm Pre-collectors of the gluteal region The abdominal thoracic duct Lymph capillaries of the dorsum of the hand - answerD What is the main task of the lymph capillaries? To ensure proper oxygenation of tissue To return blood from the interstitium to the heart To transport lymph through muscular valves towards lymph nodes To ensure the absorption of proteins and fluid from the interstitial spaces - answerD What structures make up the "venous angle"? Internal jugular and subclavian veins External and internal jugular veins Both internal jugular veins Internal jugular and cephalic veins - answerA The lymphatic organs of the body are: Thymus gland, tonsils, Peyer's patches, spleen Lymph nodes, kidneys, spleen, pancreas Thymus gland, liver, kidneys, spleen Tonsils, kidneys, Peyer's patches, pancreas - answerA All of the following factors influence lymph transport EXCEPT? External compression and stretching of tissue Muscle contraction and diaphragmatic breathing Blood sugar levels and muscle fatigue Arterial pulsation and manual lymphatic drainage - answerC Where do we find inter-axillary anastamoses? Across the transverse watershed Across the median-sagittal watershed Across the spine of scapula watershed Across the clavicle watershed - answerB
