Chapter 15, Problem 64P

Summary Introduction

To identify:

Which are the major veins that drain blood from the head, the upper limbs, the abdominal viscera, and the lower limb?

Introduction:

Veins are the vessels that carry blood from the body to the heart. The blood that they carry is deoxygenated. They flow to the heart and then to the lungs for purification. The heart then transports the purified blood to the whole body through arteries. The blood pressure in the veins is less than arteries. Owing to this, the veins are comparatively thin and have valves that prevent the backflow of the blood. The veins branches into various other veins bringing blood from the different regions of the body into the heart.
