Cardiovascular system

The Cardiovascular System is composed of the heart and the blood vessels. The main function of the cardiovascular system is to pump blood around the body. The cardiovascular System is divided into two parts, the systematic circuit and the pulmonary circuit. The systematic circuit contains oxygenated blood and the pulmonary blood contains deoxygenated blood. In order to prevent oxygenated and deoxygenated blood from mixing there is a structure called an interventricular septum. The septum separates the cardiac chambers; right and left atria and the right and left ventricles. There are four valves, which regulate backflow to the chambers. There are two types of valves, which are the atrioventricular valves and the semilunar valves. The atrioventricular…

The Cardiovascular system also known as the Circulatory System is an organ system that transports oxygen, nutrients, hormones and cellular waste products and permits blood to circulate and form cells in the body to nourish it with every heartbeat throughout the body.However, the Cardiovascular system is composed of the following organs, heart and blood vessels, including arteries, veins, and capillaries. One of the major structures of this system is the heart which functions to propel blood…

Without the heart, you wouldn't be able to basically live at all. The heart pumps blood through the body’s cardiovascular system. The blood gives oxygen and nutrients to the organs and tissues in the body and gives carbon dioxide to the lungs. We need the heart to survive and have a working cardiovascular system. The heart has four main parts: the left ventricle,the right ventricle, the left atrium, and the right atrium. A wall of muscle called the septum separates them. Oxygen-rich blood from…

1. List the functions of the cardiovascular system. What are the different types of blood vessels? Which vessels carry blood towards the heart? Which carry blood away from the heart? Where does gas exchange occur? The functions of the cardiovascular system are: pumping blood to body tissues and organs; maintaining homeostasis; and transport gases, waste, and hormones. The different types of blood vessels are: arteries, capillaries, and veins. The vessels that carry blood towards the heart are…

Compare and contrast Structure: The main objective of the cardiovascular system is to transport materials around the body with blood serving as its transport medium. Blood is contained and transported in hollow tubes known as blood vessels. The body has three main types: Arteries, capillaries and Veins. All arteries (with the exception of pulmonary and umbilical arteries) transport Oxygenated blood away from the heart to the rest of the body. They branch off into smaller structures named…

Homecare – Maintaining Cardiovascular Health According to the World Health Organization, "cardiovascular diseases are the number one cause of death globally: more people die annually from CVDs than from any other cause." The worst part about this: Most cardiovascular diseases could have been prevented by simply addressing behavioral risk factors. The heart is responsible for pumping blood throughout the body. The arteries take the blood away from the heart and the veins bring it back to it,…

Describe the structure and function of the cardiovascular system Blood vessels Arteries, veins and capillaries takes blood and nutrition to the muscles and back from the heart. Arteries take the blood that has O2 in it away from the heart under high pressure with a small diameter and it has thick muscular walls, and veins take the blood back to the heart under low pressure it has a medium thickness to it and a large diameter because it has valves to stop the blood flowing backwards.…

The cardiovascular system operates our body by distributing and circulating blood to parts of our body. The blood in our body contains red and white blood cells, plasma, and platelets. Those are then distributed through the body to the pulmonary circulation. The human heart is the engine of the pulmonary circulation (Farley,2012). Blood is then delivered to our heart. Waste from the cells of our body is removed and blood is distributed to our vines (Farley, 2012). Therefore when we engage in…

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…

CASE STUDY 1 1. The cardiovascular system consists of the following- Blood – It is a red color fluid in the body. Heart – It is also called the control center of our body. It pumps and collects blood to and from the various parts of our body. Blood vessels – Blood vessels are path through which transport medium circulates in our body. 2. The functions of cardiovascular system are as follows- Transportation- It transports blood to all the parts of body. The blood delivers oxygen and nutrients…
