"lymphocytes‚" along with proteins and fats. Lymph seeps outside the blood vessels in spaces of body tissues and is stored in the "lymphatic" system to flow back into the bloodstream. Through the flow of blood in and out of arteries‚ and into the veins‚ and through the lymph nodes and into the lymph‚ the body is able to eliminate the products of cellular breakdown and bacterial invasion. Two very large areas are of significance in this system - the right lymphatic duct which drains lymph fluid

cardiovascular system as comprising two distinct networks of arteries and veins. Galen claimed that the liver produced blood that was then distributed to the body in a centrifugal manner‚ whereas air was absorbed from the lung into the pulmonary veins and carried by arteries to the various tissues of the body. Arteries also contained blood. This was an open-ended system in which blood and air simply dissipated at the ends of veins and arteries according to the needs of the local tissue. Blood was not

ANATOMY AND PHYSIOLOGY Chronic Kidney Disease Cardiovascular System The cardiovascular system is sometimes called the circulatory system. It consists of the heart‚ which is a muscular pumping device‚ and a closed system of vessels called arteries‚ veins‚ and capillaries. As the name implies‚ blood contained in the circulatory system is pumped by the heart around a closed circuit of vessels as it passes again and again through the various "circulations" of the body. The Heart * The heart is enclosed

September 30‚ 2012 Introduction/Purpose In this lab experiment‚ I examined a pig’s heart and compared it to a human’s heart. The pig’s heart is very similar to a human’s heart by having the same structures‚ veins‚ valves‚ and chambers. I was unable to perform hands on examination on a human heart so I examined a pig’s heart. I was able to identify major areas of the heart and dissect it to examine the inside chambers and valves. This experiment helped me

right femoral vein of a healthy female. I am your pilot Kierra Lewis. While we embark on this journey‚ make sure that you keep your hands and feet inside the submarine at all times. Fasten your seat belts and let’s start our journey! We will begin our journey in the femoral vein. As you can see the femoral vein is a blood vessel that is responsible for carrying blood from the leg back to the heart via the iliac veins. This is the largest vein in the groin area. Any blockages in this vein can lead to

The body is a very complex mechanism. There are many different veins and arteries that flow throughout the body. With there being many different veins and arteries throughout the body there are multiple paths to get to the lower lobe of the lung. In this paper we will discuss how to get from the femoral vein to the lower lobe of the lung. The path that I have chosen to discuss to get to the lower lobe of the lung from the femoral vein involves the inferior vena cava‚ AV valve‚ right ventricle‚ pulmonary

Task 1a: Erythrocytes: These are also known as red blood cells and contain haemoglobin with their primary function being to carry oxygen from the lungs then disperse it into the tissues throughout the body through a series of capillaries. The distinctive red colour of the erythrocytes or red blood cells is due to their contents of haemoglobin. In order to facilitate its purpose the erythrocytes can be described as biconcave in shape therefore enabling them to diffuse oxygen around the body with
