Explanation The blood pressure of the body is maintained against the gravity by a variety of methods such as the contraction of the skeletal muscles and the respiration through lungs that alters the blood flow and maintains the blood pressure. The skeletal muscles put force on the venous system by contracting and relaxing which sends the blood to the heart. The back flow is prevented by the valves in the veins of the lower limbs...

Chapter 21, Problem 24RQ

Summary Introduction

To determine:

The method in which the blood pressure is maintained in the veins against the gravity.

Introduction:

The vessels that carry and bring back blood from the heart are of different types namely artery, veins, arterioles, venules and capillaries. Veins carry the deoxygenated blood from different parts of the body to the heart and arteries carry oxygenated blood from heart to the rest of the body. Capillaries transfer nutrients and oxygen to the cells.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth. Did a patient relationship with the transfusing hospital exist?
