Physiology of visceral systems «Blood, circulation and respiration» : manual for individual work of second-year students

Abstract

The blood, heart and blood vessels constitute the circulatory system and provide a link between the bodies’ internal compartments and external environment. More specifically, the blood transports nutrients from gastro-intestinal tract to cells, oxygen from respiratory system to cells, wastes from cells to excretory organs; it carries hormones from endocrine glands to target cells and aids in body thermoregulation.
