This document outlines the key topics and concepts covered in a chapter on the circulatory system and transport in humans. The chapter introduces the anatomy of the circulatory system, including the heart, veins, and arteries. It discusses the tissue fluid and its components like blood plasma, red blood cells, white blood cells, and platelets. The chapter also covers the cardiac cycle, exchange of substances via the lymphatic system, hemoglobin, blood types, and common heart diseases like myocardial infarction. Learning objectives focus on describing the circulatory system, tissue fluid, cardiac cycle, and heart diseases.
