Pulmonary vein

Introduction: The heart is part of the circulatory system which pumps blood and supplies oxygen throughout our body(Jacobs). Pumped through a network of arteries and veins, blood is a very important part of our body. Without blood, we could not live. This is because it keeps us warm, fights off infections, and helps get rid of waste(Durani). Blood also transports oxygen and hormones throughout our body. Our circulatory system is made up of the heart and blood vessels. They also include arteries, veins, and capillaries. There are two parts to the circulatory system: the pulmonary circulation and the systemic circulation. The pulmonary circulation is a short loop from the heart to the lungs and then repeats. The systemic circulation sends blood from the heart to the other parts in our body and repeats(Durani). Circulation Veins and arteries have many differences. One difference is veins have a thinner wall than arteries do. Veins can widen as the amount of blood that passes through them increases. Arteries have strong and flexible walls that allow them to adjust blood that flows to body parts. The veins and arteries are apart of the of the circulatory system. In…

body. The first are the arteries which face high blood pressure levels due to the fact that they take blood away from the heart, Because of this they are thicker and more elastic then the other blood vessels. Branching off of the arteries are arterioles which carries blood to the second type of blood vessels the capillaries. These are the smallest and thinnest of the three types of blood vessels but also the most common in the body. They can be found running through almost every tissue in the…

The cardiovascular system is the system in which it helps to circulate blood throughout your entire body. However, that's not its only function. It also helps to transport both oxygen and carbon dioxide, hormones, numerous cells, and also nutrients to the body's tissues and organs. This system consists of the heart, blood, and also blood vessels. The heart is a muscular structure that helps push the blood to flow throughout the body. It is composed of three layers the pericardium (around or…

The red blood cells are used to carry the oxygen, whilst the white cells are there to make up part of the immune system. Platelets are needed for clotting in the body and the plasma is a liquid in which the other components float in (Next slide). Some common problems that can occur in the Cardiovascular System is an Aneurysm and Varicose Veins. Aneurysms occur when there is a weak spot in the wall of an artery. Varicose veins, is quite common, it is when there are problems with valves and…

Introduction: The heart plays a crucial role in the human circulatory system. The large organ pumps the blood through arteries, veins, and capillaries to distribute oxygen and nutrients to the body. The circulatory system also plays a part in removing our waste products. Humans have double circulation, meaning the blood passes through the heart twice before completing one round; this allows for the blood to be “re-pressurized”. Once the right side of the heart receives blood from the body,…

1. Explain the relationship between the skeletal and muscular systems. So in the simplest terms, the skeletal system (Bones) make it so that way you have structure in you’re not a blob of skin and cartilage, and the muscular system makes it so that way you can get up and move around. The skeletal system provides the framework for your body, while the muscular system consists of soft tissues that support the skeleton. 2. Why is the circulatory system important? Because it circulates the blood in…

The circulatory system is composed of vessels that take blood from the heart, thin-walled capillaries where exchange occurs, and vessels that return blood to the heart. Blood is pumped by the heart simultaneously into two ways the pulmonary and systemic circuits. The pulmonary system takes blood through the lungs where gas exchange occurs and the systemic system transports blood to all parts of the body where exchange with tissue fluid takes place. In practical terms, we can think of the…

The cardiovascular system The cardiovascular system consists of the heart, blood vessels and approximately the 5 litres of the blood that the blood vessels transport. The cardiovascular system is powered by the body’s hardest working organ. The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from your body. The main structures of this system is the heart the blood vessels and blood. Delivery of oxygen and nutrients The pulmonary circuit carries blood…

- Inner Layer; An inner endothelial cell layer called tunica intima lines the arteries and veins. The tunica intima, is a single layer of squamous epithelial cells that lines the inner surface of the entire cardiovascular system. In many veins, the tunica intima is equipped with pockets that act as one-way valves. These valves prevent the back flow of blood and allow the veins to act as supplemental pumps that help to keep the blood following in one direction, back toward the heart. The activity…

hormones. The different types of blood vessels are: arteries, capillaries, and veins. The vessels that carry blood towards the heart are veins and the vessels that carry blood away from the heart are arteries. Gas exchange occurs in the capillaries. 2. Describe the layers of blood vessels. Describe the differences between arteries and veins. The layers of blood vessels are: a hollow interior (lumen), contains an outer…
