An adult giraffe (Giraffa camelopardalis) has a heart that lies approximately 2 m below the top of the head when its neck is fully extended. Calculate the minimum diastolic pressure that a giraffe must have (in mm Hg). Hint: what is the absolute minimum blood pressure a giraffe could have at the very top of its head

Sagot :

Answer:

159.01 mmHg

Explanation:

position of Heart = 2m  below the top of the head  given that the neck is fully extended

Determine the minimum diastolic pressure

Minimum diastolic Pressure = 1060 kg/m^3 * 10 m/s^2 * 2m

                                               = 21200 kg/m^2

convert the value to Pa

21200 kg/m^2 = 21200 Pa

( 1 pa = 0.00750062 mmHg )

Therefore : minimum diastolic pressure = 21200 * 0.00750062 = 159.01 mmHg

The minimum diastolic pressure that a giraffe must have is 150 mmHg

Diastolic Blood pressure

Diastolic Blood pressure is the pressure on the walls of your arteries between heartbeats, that is when the heart is resting.

  • The minimum diastolic diastolic blood pressure = absolute minimum blood pressure a giraffe could have at the very top of its head.

Pressure formula

P = hpg

where;

P = pressure

h = height difference

p = density

g = acceleration due to gravity

Density of blood = 1000 kg/m^3

h =2.0 m

g = 10 m/s^2

Pressure = 1000 × 2.0 × 10

Pressure = 20000 Pascal or 20 kpa

Converting to mmHg

1 kpa = 7.50 mmHg

20 kpa = 20 × 7.50

Pressure = 150 mmHg

Therefore, the minimum diastolic pressure that a giraffe must have is 150 mmHg
