question-functions of the lymphatic system - answer-fluid balance, protection, and absorption of fats question-lymphatic circulation is - answer-one-way system that begins in the tissues and ends when the lymph joins the blood question-lymphatic capillaries - answer-walls (endothelium) flattened epithelial cells, more permeable, cells overlap slightly, forming one-way valves, lacteals absorb fat, arise blindly (closed at one end) question-lymphatic vessels - answer-include superficial and deep sets, right lymphatic duct and thoracic duct question-right lymphatic duct - answer-short vessel receives only lymph that comes from the body's superior right quadrant and empties into right subclavian vein near heart question-thoracic duct - answer-receives lymph from all parts of the body except those superior to the diaphragm on the right side; drains into thee left subclavian vein question-cisterna chyli - answer-first part of the thoracic duct enlarged to form cistern or a temp storage pouch question-movement of lymph toward heart is caused by: - answer-valves in lymphatic vessels contraction of lymphatic vessels skeletal muscle contraction
breathing question-roughly how many lymph nodes are in the body? - answer-about 600 question-lymphoid tissue - answer-distributed throughout the body and makes up specialized organs question-lymph nodes - answer-small masses of lymphatic tissue that filter the lymph question-lymph - answer-fluid that circulates in the lymphatic system, clear fluid; question-hilum - answer-indented area that is the exit point for efferent lymphatic vessels carrying lymph out of the node question-cervical nodes - answer-located in the neck in deep and superficial groups, drain parts of head and neck question-axillary nodes - answer-located in armpits question-tracheobronchial nodes - answer-near the trachea and around the larger bronchial tubes question-mesenteric nodes - answer-found between the two layers of peritoneum that form the mesentry, 100-150 nodes
question-tonsils - answer-protect against inhaled or ingested contaminants; trap pathogens;surgery to treat if become infected or swollen and reoccurs which makes swallowing and breathing difficult question-palatine tonsils - answer-oval bodies located at each side of the soft palate; generally what one refers to as "tonsils" question-pharyngeal tonsil - answer-commonly called adenoid; located behind the nose on the posterior wall of pharynx question-lingual tonsils - answer-little mounds of lymphoid tissue at the posterior of the tongue question-lymphadenopathy - answer-disease of the lymph nodes question-lymphedema - answer-swelling that obstructs lymph flow question-four phases of respiration - answer-pulmonary ventilation, external gas exchange, gas transport in the blood, and internal gas exchange question-pulmonary ventilation - answer-exchange of air between the atmosphere and the air sacs (alveoli) of the lungs question-external gas exchange - answer-occurs in the lungs as oxygen diffuses from the air sacs into the blood and carbon dioxide diffuses out of blood to be eliminated
