Welcome to an On-Line Biology Book Table of Contents. Click on the underlined items to go to those chapters. The text items are modified lecture outlines I have developed over the many years of teaching college-level introductory biology. Use of my text for educational purposes is encouraged and appreciated, however many illustrations are taken off the web, and I have indicated the source page (when that page still is an active link) and tried to provide a link back to the original.

The Circle Of Blood On average, your body has about 5 liters of blood continually traveling through it by way of the circulatory system. The heart, the lungs, and the blood vessels work together to form the circle part of the circulatory system. The pumping of the heart forces the blood on its journey. The body's circulatory system really has three distinct parts: pulmonary circulation, coronary circulation, and systemic circulation. Or, the lungs (pulmonary), the heart (coronary), and the rest of the system (systemic). Each part must be working independently in order for them to all work together. Back to Systems

WelcomeThe Human BodyNew KidneyGift of LifeGift Goes On Circulatory System How the Blood Gets Around the Body The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. This process is called circulation. The main parts of the system are the heart, arteries, capillaries and veins. As blood begins to circulate, it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body. T ...

Circulatory system III. Circulatory System A. Overview 1. Central role [Fig. 39.2] - Internal bulk transport system; carries oxygen, nutrients to body cells, carries secretions, metabolic wastes away. Interacts with digestive, respiratory and urinary systems. 2. Three components - Blood = fluid (connective tissue) composed of water, solutes, cells, "formed elements". - Heart = muscular organ that pumps blood through animal's body (muscle contraction converted to pressure) - Vessels ...

The Circulatory System The Circulatory System is the main transportation and cooling system for the body. The Red Blood Cells act like billions of little UPS trucks carrying all sorts of packages that are needed by all the cells in the body. Instead of UPS, I'll call them RBC's. RBC's carry oxygen and nutrients to the cells. Every cell in the body requires oxygen to remain alive. Besides RBC's, there are also White Blood Cells moving in the circulatory system traffic. White Blood Cells ...
