    Answer:

       P = 10135.6 Pa

    Explanation:

    For this exercise we use that the pressure varies with the height

               P = P₀ + ρ g h

    where h is the height from the head to the heart, which is approximately

    h = 40 cm = 0.40m  and P₀ is the head pressure P₀ = 6000 Pa

              P = 6000 + 1055 9.8 0.40

              P = 6000 + 4135.6

              P = 10135.6 Pa
