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

Arteries carry blood away form the heart the extremities and organs. They have typical three layer blood vessel wall structure with a thick tunica media. The walls of arteries are highly compliant due to the elastic fibres present. The wall thickness of the arteries varies in based on the proximity to the heart. The elasticity of arteries allows pressure absorption from the left ventricle of the heart as it pumps blood into the arteries. There are two significant types of arteries‚ elastic and muscular

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

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

is to bring oxygen bearing blood to all the tissues of the Body. During Pulmonary Circulation blood circulates to and from the lungs to release carbon dioxide and pick up new oxygen. The veins bring waste rich blood back to the heart entering the Right Atrium through out two large veins Inferior and Superior Vena Cava. The Right Atrium fills with waste rich blood and contracts pushing blood out through a one way valve into the right ventricle. These one way valves are to prevent

small intestine into amino acids. The villi on the walls of the small intestine absorb the amino acids into the hepatic portal vein. Hepatic portal vein is a special vein that transports digested material from the small intestine to the liver. The liver plays a big role in maintaining the level of protein in our body. It absorbs all amino acids from the hepatic portal vein. If the body needs proteins‚ they will pass through the liver into the blood stream to be used by the body cells to make protein
