Write An Essay On The Cardiovascular System

The Pintails heart is like a mammals consisting of four chambers, two ventricles and two atria. The left ventricle pumps blood to all major organs in the body and throughout the rest, only excluding the lungs. This causes the left ventricle to be larger and more muscular. The lungs are fed blood from the right ventricle, which is the only the only function of that ventricle. The oxygenated blood coming from the lungs is fully separated from the oxygenated blood coming from other parts of the body.

Veins transport blood to the heart and lungs at low pressure after receiving it from the capillaries. Valves inside the veins keep blood moving in one direction. The human body's arterial system branches out from one main artery, the dorsal aorta. Like veins, arteries have three layers: an outer layer of tissue, an inner layer of epithelial cells and a layer of muscle in between.

Right ventricle pumping the deoxygenated blood through the pulmonary valve and artery to the lungs. But left ventricle pumping oxygenated blood through the aorta and valve into the circulation. The aorta is main artery of the body and it is top of heart which carries the blood away from the body. The coronary artery supply oxygen-rich blood to the heart muscles. Pulmonary veins are large vessels that carrying oxygenated blood from the lungs to the left atrium which it is draining.

Heart, lungs and the Rest of You By: Olivia Abel 1.Explain how the blood flows throughout your lungs, heart and the rest of your body.   Heart: Your left and right side of your heart work together to pump blood to and throughout your body which is separated by muscular tissue called the septum. In the right side blood enters through two large vein which are the inferior and superior vena cava, emptying poor oxygen blood from the body to the right reticulum. When the left side enters from the pulmonary veins and empties oxygen rich blood from the lungs into the aorta going throughout the body.

You should check a person if you think that he or she has suffered cardiac arrest. If you find a person unconscious, or see him or her collapse, then you will need to check to see if he or she is responsive. Shake the person and shout to make sure that he or she is not sleeping. Pinch an infant or young child to try to wake him or her up.

If a person does not have a cardiovascular system that is in good working order, it can be a fatal situation. Along with pumping blood to the body, the cardiovascular system also brings oxygen and nutrients to all of the different organs and tissues within the body. As our blood makes its circuit journey from the heart to the extremities and then back to the heart, waste is removed from the cells as well. For the cardiovascular system to function at an optimal level, it needs to be healthy and fit.

1. List the structures and functions of the cardiovascular system. Do not forget blood and vessels are part of this system. The cardiovascular consists of the heart, blood vessels and blood. It has three functions one of them is that it transports nutrients, oxygen and hormones to cells throughout the body and removes wastes such as carbon dioxide and nitrogenous waste.

Cardiovascular Response to Exercise Introduction The cardiovascular system, comprising of blood vessels, the heart, and blood, responds predictably with regards to the increased exercise demands (Centers for Disease Control and Prevention 62). In a sense, a series of cardiovascular changes take place in response to physical exercise for providing enough blood supply to the constricting muscles, to dissipate the energy produced by active muscles, and to maintain the supply of blood to vital organs of the body such as the brain and the heart (Agarwal et al. CC06).

The Effect of Optimism on Cardiovascular Health Optimism and the beneficial effect it has when related to improved cardiovascular health has been the subject of a many studies. In these studies, several aspects could be considered as exemplary desirable consequences of optimism that may result in enhancing the well-being of the cardiovascular system. According to recent research, optimism has been shown to increase the likelihood of living longer in cardiovascular patients (American Heart Association, 2013). Living a longer life should be everyone’s ultimate health goal, and of particular relevance here is the fact that cardiovascular disease is the leading cause of death in the United States (Centers for Disease Control and Prevention, 2015). In what ways might being optimistic ameliorate cardiovascular health and possibly increase longevity?

Exercise and the cardiovascular system The cardiovascular system is also known as the circulatory system this system is made up of the heard and the connected tubes (vessels) called arteries, veins, and capillaries. This system contains the blood that is pumped by the heart around the whole body (over and over again). The circulatory system may not be the only system that controls homeostasis (homeostasis is maintaining a stable state of the entire body) but it plays a vital role. The important position that the circulatory system has in controlling homeostasis depends on the steady and regulated stream of blood through the arteries; veins and capillaries that go throughout our body and enter every tissue and can reach every cell in the body.

The objective of this experiment is check how heart chambers, vessels and valves of the heart help the heart to achieve its function of pumping blood all over the body. In addition, this experiment would help us understand the double circulation of blood and reasons why it is vital for mammalian organisms. Due to the complexity of mammalian organisms, the exchanges of substances such as oxygen, nutrients and hormones cannot rely on diffusion itself (Kent, 2013). The transportation

The heart, blood, and blood vessels all form the circulatory system, also known as the cardiovascular system. As one of the most important systems in the human body, the circulatory system transports oxygen and nutrients to tissues and removes any waste products. Without the circulatory system, your organs wouldn 't be able to function, causing death. With the blood vessels taking blood around the body, the heart pumps all this blood.

Doctors are able to diagnose heart failure by carrying out tests in patients who present with the symptoms. These tests include blood tests and an echocardiogram (ECG). Blood tests can be used to check cholesterol levels and for a substance called natriuretic peptide, which the heart secretes into the blood if it is damaged or overworked. An ECG is used to look in detail at the structure of the heart, such as testing how well the valves are working, systolic function, diastolic function and, most importantly, it measures the function of the left ventricle by measuring the left ventricular ejection fraction, which is an estimate of how much of the blood that enters the left ventricle is pumped out when the heart muscle contracts

All of these organ systems need to help to make up the

The main components involved in this system in heart, blood, and blood vessels. Blood is a oxygen and nutrients filled fluid that has plasma, red blood cells, white blood cells, and platelets and removes all waste materials from body tissues. Without the brain the circulatory system does not work, heart function and fluid circulation does not work unless they are triggered by the brain. The digestive system is a group of organs working together to convert food into energy and basic nutrients to help the entire body. This system consists of the salivary glands, pharynx, mouth, esophagus, liver, gallbladder, stomach, pancreas, small and large intestine, and the anus.
