Question

As blood volume decreases, blood pressure ____________ . If greater than ____________ of the blood volume is lost from the blood vessels, the ____________ division of the autonomic nervous system (ANS) is activated, bringing about ____________ vasoconstriction of blood vessels, increased heart rate, and force of heart contraction in an attempt to maintain blood ____________ . These processes are effective in maintaining blood pressure until approximately ____________ of the blood is lost. Blood loss greater than this amount results in insufficient blood ____________ within the blood vessels, and blood pressure decreases to levels unable to support life.

Answer 1

The answers that fills in the gaps as Blood volume decreases, blood pressure---.  If greater than-- of the blood volume are :  a) Decreases,  b) 40%,  c)sympathetic,  d)increased,  e)pressure,  f)10%,   g) volume

As blood volume decreases, blood pressure decreases. If greater than 40% of the blood volume is lost from the blood vessels the sympathetic division of the autonomic nervous system (ANS) is activated, bringing about  Increased vasoconstriction of blood vessels, increased heart rate, and force of heart contraction in an attempt to maintain blood Pressure . These processes are effective in maintaining blood pressure until approximately 10% of the blood is lost. Blood loss greater than this amount results in insufficient blood Volume within the blood vessels, and blood pressure decreases to levels unable to support life.

Although your question is incomplete attached below is the missing data that is required to fill up the missing gaps.

The blood volume found in mammals is directly proportional to the blood pressure therefore as the blood volume increase the blood pressure will also increase in the same proportion, also a decrease in blood volume leads to a decrease in blood pressure

Hence we can conclude that the answers respectively are :

Decreases,  40%,  sympathetic,  increased,  pressure,  10%,  volume
