Purpose:
To investigate the structure of the heart.
Introduction:
Every day, the approximately 5 liters of blood in your body travel many times through about 97,000 kilometers of blood vessels that branch and cross, linking the cells of our organs and body parts. From the hard-working heart, to our thickest arteries, to capillaries so thin that they can’t be seen with the naked eye, the cardiovascular system is one of the most important systems in our body.
The central organ of the Cardiovascular System is the Heart, the muscular organ pumps blood through an intricate network of Blood Vessels to all parts of the body. The heart sends blood around the body. The blood provides the body with the oxygen and nutrients it needs. It also carries

Mammals have four-chambered hearts and double circulation. The double-loop circulation is similar to amphibians and reptiles, but the oxygen-rich blood is completely separated from oxygen-poor blood. The left side of the heart handles only oxygenated blood, and the right side receives and pumps only deoxygenated blood. With no mixing of the two kinds of blood, and with a double circulation, delivery of oxygen to all parts of the body is enhanced. The gross anatomy of the human heart is the same as the sheep’s heart that was dissected. The heart is located, between the lungs, and behind the sternum. At least one blood vessel attaches to each of the chambers. It usually beats from 60 to 100 times per minute, but can go much faster when it needs to. It beats about 100,000 times a day, more than 30 million times per year, and about 2.5 billion times in a 70-year lifetime.
Problems with the cardiovascular system are common — more than a sixth of Australians have some type of cardiac problem. Cardiovascular problems affect all age groups. Heart and circulatory problems are grouped into two categories: congenital, which means the problems were present at birth, and acquired, which means that the problems developed some time after
Transportation has many roles in the cardiovascular system. First, our blood carries oxygen from our lungs to all of our tissues. While taking oxygen to our tissues, it also picks up carbon dioxide from them and takes it to our lungs to be removed from our body. Second, it delivers nutrients from our digestive tract to all of our body’s tissues. Third, it takes waste to our kidney’s to be removed from our body. Fourth, it
The cardiovascular system consists of the heart, blood and blood vessels. The cardiovascular system is the major transport of materials to and from the cells. Blood is carried from the heart around the body via the arteries and the blood is then carried back to the heart via the veins. The
The cardiovascular system has a wide variety of organs. Which includes the veins and arteries and the heart. Cardiovascular system is essential to life. The heart pumps blood into our system. The veins are a passageway which white and red blood cells move. White blood cells which defend our body from diseases and illnesses. The red blood cells remove the carbon dioxide from our body and transport it to the lungs. Our heart is very important, if we did not have a system pump blood into our body. The device used is our arteries carry blood from our heart to our other organs. The cardiovascular system contains platelets. Platelets repair any damage done inside of vessels or and helps prevent severe blood thrombus . Imagine if our heart stop pumping blood and deliver oxygen.We also stop breathing and die. Our cardiovascular system is extremely important to life.
Cardiovascular system is powered by the body’s hardest-working organ the heart, which is only about the size of a closed fist. Even at rest, the average heart easily pumps over 5 litres of blood throughout the body every minute. The cardio vascular system delivers oxygen to the body tissues from the lungs and nutrients to the liver from the intestines. The cardiovascular system also removes carbon dioxide from the cells to the lungs, to be excreted and also removes waste products from the liver to the kidneys. The cardiovascular system transports white blood cells, Antibodies and hormones to different parts of the body.
The heart is a very wonderful and the hardest working organ in our body. It constantly pumps oxygen and nutrient-rich blood throughout your body to maintain life in it. Every time when the heart beats, it pumps blood through the system of blood vessels, which is called the circulatory system. These vessels are muscle-elastic tubes that deliver blood to every part of the body.
According to the Discovery Channel, the Cardiovascular System is the generator that drives the bodily machine of humans (Discovery Channel, “Your Cardiovascular System,” 2016). Its multiple functions and complex anatomy helps humans get through vital tasks (National Geographic, “Heart,” 1996). Such as, breathing, blood circulation, and food intake. In other words, the cardiovascular system delivers and transports oxygen and carbon dioxide throughout the body, transports and circulates blood throughout the body, distributes nutrients and food within the body and transports waste products out of it (National Geographic, “Heart,” 1996). It also takes part in the circulation of hormones (National Geographic, “Heart,” 1996). The cardiovascular
Heart= The heart is around the size of a persons fist, it is composed of 2 sides and four chambers, the left and right atria and the left and right ventricles. The atria’s are at the top of the heart, they receive blood from various parts of the body. The two ventricles are located on the bottom of the heart and pump blood away from the heart. The right ventricles responsibility is to pump the deoxygenated blood to the lungs, while the left ventricle pumps the oxygenated blood to the rest of the body. Between the chambers there are valves in the heart, the valves control the flow of blood, making sure it flows in one direction.
Referring to Louise Tucker 5th edition, the heart is an organ that pumps blood through the body via the circulatory system, supplying nutrients and oxygen to the tissues and removing carbon dioxide and other waste products.
The study of the heart and circulatory system, together referred to as the cardiovascular system, has been a topic of interest for many centuries. As one of the most complex and sophisticated systems in the human body, the journey towards our current understanding of it’s form and function has been a long one. Even cardiology, the study of the heart and circulatory system is still relatively in its infancy as a medical specialty.
Cardiovascular system consists of the heart, blood vessels and the blood inside them. It’s responsible for transporting oxygen, nutrition and waste products throughout the body. The heart is the circulatory pump that transports blood to the entire body. Cardiovascular system has two circulations: systemic and the pulmonary circulations.
The cardiovascular system consist of three organs the heart, blood vessels, and blood. They work together in order to provide oxygen throughout the whole body, the heart composed of cardiac muscle is the main organ in the human body without it we won’t be able to live it, its function is mostly to pump blood throughout the whole body. The blood vessels are composed mainly by smooth muscle throughout the whole body carrying blood such as the arteries and the veins, which takes carbon dioxide and other waste out of the body. There are two types of blood cells white and red blood cells. The white blood cells main function is to help maintain the body’s immune system, while the red blood cells are used for carrying
The left side of the heart carried out systemic circulation; which pumps the blood the right side of the heart, which then it pumps the blood to the lungs, which is part of the pulmonary circulation. The heart consists of two chambers; with one above the other. The chambers are connected by valves to make sure the blood flow remains flowing in one directing. Blood enters the left atrium (top chamber) from the lungs, and through the ventricle (lower chamber), where it is then pumped out and around the body.
The heart is a muscular organ that pumps blood to and from all areas of your body with the help of veins, capillaries and arteries. It has four chambers containing two atria and ventricles. The atriums receive blood from the veins and the ventricles pump blood into the arteries.it also has inlet and outlet valves that ensure blood flows in the right direction. The heart wall is made up of 3 layers- the epicardium, the myocardium and the endocardium.
The transporting of blood through the whole body is done by the cardiovascular system. This one continuum of blood vessels and arteries and is used to transport blood away from the heart and veins transport the blood back toward the heart. Capillaries are used to transport blood to tissues cells and the exchanging site for nutrients, gases and wastes. The heart is also a part of the cardio vascular system Approximately the size of a person’s fist the heart is a Hollow cone shaped, Weighs approximately 300g, 2/3 left of the median plane And is located in the bony thorax between the lungs. The pointed apex of the heart is pointed toward the left hip and rests on the diaphragm. The heart consists of the myocardium which is the middle muscle layer of the heart. The endocardium which is the inner most layer of the heart and The Pericardium is a double layer of serous membrane with serous fluid in between. It protects the heart and anchors it to surrounding structures the pericardium which a visceral inner and partial outer layer of the heart.
The body system that I chose to write my research paper on is the cardiovascular system. The cardiovascular system is made up of your heart, your blood vessels, and also your blood. Your heart is notable as the pump in the cardiovascular system; it trusts your blood to organs, tissues, and cells in your body. The blood vessels also help the regulation of blood course in your body as well. The two main circuits in your body are called the pulmonary and systemic circuits. The pulmonary circuit helps your blood flow through your lungs, whereas the systemic circuit helps your blood flow through your body. Your blood holds the nutrients and oxygen that can carry the wastes in which need to be removed, it is removed from several organs such as you kidneys and your lungs. The heart is made up of two sides, simply named the right and the left side, and is made up of four different chambers. The top two chambers are on each side of the heart. They are known as the left and right atria. Your left atrium gains blood from your lungs, whereas the right atrium gains blood from the rest of your body. The two bottom chambers are known as the left and right ventricles and they disperse blood out to your body. The right ventricles release blood to your lungs but left push blood to the rest of your body. The chambers on the right side provide the pulmonary circulation while the chambers on the left side provide the systemic circulation. Valves help prevent the blood from flowing in the wrong
