		Circulatory System ^Votes:0 Welcome The Human Body New Kidney Gift of Life Gift 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. The blood leaving the aorta is full of oxygen . This is important for the cells in the brain and the body to do their work. The oxygen rich blood travels throughout the body in its system of arteries into the smallest arterioles. On its way back to the heart, the blood travels through a system of veins Read More Go to Site

		Introductory Anatomy: Circulatory System & Blood ^Votes:0 Faculty of Biological Sciences, University of Leeds These pages have been left in this location as a service to the numerous websites around the world which link to this content. The original authors are no longer at the University of Leeds, and the former Centre for Human Biology became the School of Biomedical Sciences which is now part of the Faculty of Biological Sciences . Introductory Anatomy: Circulatory System & Blood Dr. D.R.Johnson Perhaps the most important thing to remember about the circulatory system is its variability. This is because of the way the circulatory system develops: the early embryo is essentially a blood filled sponge - intricate network. Most of this is removed during development, leaving remnants governed by highest flow and pressure. Its plasticity is also sh Read More Go to Site

		Lecture 25: Circulatory system ^Votes:0 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 = tubes for directing transport of blood B. Two basic types of circulatory systems [Fig. 39.3] 1. Open circulatory systems - blood is pumped from a heart (or heart-like organ) into large cavity where organs are "bathed" in hemolymph - blood and tissue fluid not distinguishable - Arthropods, m Read More Go to Site

		NOVA Online \| Cut to the Heart \| Map of the Human Heart ^Votes:0 --> Map of the Human Heart Let's get straight to the heart of the matter--the heart's job is to move blood. Day and night, the muscles of your heart contract and relax to pump blood throughout your body. When blood returns to the heart, it follows a complicated pathway. If you were in the bloodstream, you would follow the steps below one by one. Oxygen-poor blood (shown in blue) flows from the body into the right atrium. Blood flows through the right atrium into the right ventricle. The right ventricle pumps the blood to the lungs, where the blood releases waste gases and picks up oxygen. The newly oxygen-rich blood (shown in red) returns to the heart and enters the left atrium. Blood flows through the left atrium into the left ventricle. The left ventricle pumps the oxygen-rich blood to a Read More Go to Site

		The Circulatory System ^Votes:0 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 are the paramedics, police and street cleaners of the circulatory system. Anytime we have a cold, a cut, or an infection the WBC's go to work. The highway system of the Circulatory System consists off a lot of one way streets. The superhighways of the circulatory system are the veins and arteries. Veins are Read More Go to Site

		The Heart and the Circulatory System ^Votes:0 -Advertisement- Access Excellence Classic Collection The Heart and the Circulatory System by Roger E. Phillips, Jr. Human heart, frontal view (Carolina Biological Supply Company.) Introduction Imagine that you are living in the year 1535, and that you don't feel well. You have had some problems with fatigue, feeling a little more tired than usual when you walked to the market and back. You tell this to your physician, and he sends you to another physician down the street, telling you there may be some problem with your circulation. When you get to the new physician, he tells you to take off your shirt and lie down on the bench. After a quick look in your mouth, he says your vital blood is probably O.K. But he's concerned that maybe your nutritive blood is not being made fast enough. Then h Read More Go to Site
