Answer 1

Answer:

While your body is at rest your heart beats somne 70 times a minute. Its rhythmic contractions causes about 5 liters of blood to circulate to your toes, back and elsewhere.

Answer 2

Answer:

PHYSICS

The human heart forces 4×10−3m3 of blood per minute through the arteries under a pressure of 0.13m. Calculate the horsepower of the heart. The density of blood is 1.03×103kg m−3. Take g=9.8ms−2 and 1 H.P. =746W.

ANSWER

Given data 

Volume −(V)=4×10−3m3

(h)=.13m

density (f)=1.03×103kgm−3

(g)=9.8m/sec2

P=fgh

⇒1.03×103×9.8×.13

=(9.8)(1.03)(.13)×102

P=1312.22Pa

t=1minute=60sec

Power tw=tFs=AtFAS=tPv

Power =
