Question 7:
Answer: The process of passage of fluid including nutrients and oxygen through the circulatory system ( arterial blood) to a capillary bed in a tissue or an organ is referred to as "perfusion." Hence, option 3 is the correct answer.
Hypovolemia is defined as a state of decreased intravascular volume. It involves loss of extracellular fluid.
Ischemia is a condition that leads to inadequate supply of blood to heart muscles or an organ of the body.
Inflammation is a complex biological process that functions to eliminate damaged tissues from the original insult. It is body's response to damaged cells and pathogens.
ARDS ( Acute respiratory distress syndrome) occurs due to build of fluid in the alveoli of the lung. Hence, options 1, 2, 4, 5 are incorrect.
