Table 14.2

Question 1

Increases capillary filtration pressure so that more tissue fluid is formed at the arterial end of capillaries

Answer 1

Increased blood pressure or Venous obstruction

Question 2

Decreases osmosis of water into the venular ends of capillaries. Usually a localized tissue edema due to leakage of plasma proteins through capillaries during inflammation and allergic reactions. Myxedema due to hypothyroidism is also in this category

Answer 2

Increased tissue protein concentration

Question 3

Decreases osmosis of water into the venular ends of capillaries. Maybe caused by liver disease (which can be associated with insufficient plasma protein production), kidney disease (due to leakage of plasma protein into urine), or protein malnutrition

Answer 3

Decreased plasma protein concentration

Question 4

Infections by filaria roundworms transmitted by a certain species of mosquito block lymphatic drainage, causing edema and tremendous swelling of the affected areas

Answer 4

Obstruction of lymphatic vessels
