Title: Respiratory system Post by: sweetangel on Jan 20, 2012 The following is a list of different blood pressures taken at various points along the circulatory system of one individual:
Point 1: 70/40 mm Hg Point 2: 90/60 mm Hg Point 3: 15/105 mm Hg Which point likely represents the blood pressure at the aorta? Explain. Why would the pulmonary artery pressure be less than the pressure in the aorta? How does blood pressure change as one move further away from the heart? Why?

2. The right side of the heart is weaker, since it's only pumping blood to the lungs. 3. The heart is the pump and so makes the pressure. |
