How Is Blood Pumped Throughout the Body

The atrium chambers are small and collect blood returning to the heart from the systemic or pulmonary circulation. The ventricles are larger than the atrium chambers and they pump blood out into the circulation. The right atrium and right ventricle are separated by the tricuspid valve. The tricuspid valve has three flaps that prevent backflow of the blood from the right ventricle into the right atrium. The left side of the heart has a mitral valve also known as the bicuspid valve that consists of two flaps that separates the left atrium and left ventricle. The heart has a thick wall that is mainly of muscle and is constantly contracting and relaxing through every heartbeat. The hearts wall has three layers of tissue which consist of the innermost layer called the endocardium which is a smooth, thin membrane that lines the inside of the champers of the heart and forms the surface of the valves. The second layer is the middle layer that is called the myocardium. It is the muscular wall of the heart and is made of many layers of cardiac muscle which is striated and involuntary muscle tissue. Then the outer layer of the heart is the epicardium that is a double layered fibrous sac that covers and protects the heart.

Inside the heart the four chambers were clearly defined and hollow. The wall on the left side of the heart was much thicker and firmer than the wall on the right side. The wall on the right side was very thin. The valves appeared stringy, stretchy and very long.

Now, let's talk how the heart works. The heart is divided into two halfs. Each side has a upper and a lower chamber. The upper right chamber revives poor-oxygen blood from the body. The lower right chamber pumps

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).

You have four chambers in your heart. Two atria in the upper half of the heart and two ventricles

The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body. The heart has four chambers and four valves and is connected to various blood vessels. Veins are blood vessels that carry blood from the body to the heart. Arteries are blood vessels that carry blood away from the heart to the body.

Your Heartbeat is your four valves pumping blood. Your valves include the Mitral valve, the Aortic valve, the Bicuspid valve, and the Tricuspid valve. Valves allow blood to flow to your four chambers the Atrium and the Ventricles. Arteries and Veins let blood flow around your body, the veins right next to your

A healthy heart pumps blood continuously through the circlutory system. It’s normal size is a little larger than a fist. The heart has four chambers, two on the right and two on the left. The two upper chambers are called the atria and the lower two are known as the ventricles. The right atrium takes in deoxygenated blood from the rest of body and sends it back out to the lungs through the right ventricle where the blood becomes oxygenated. Oxygenated blood travels from the lungs to the left atrium, then onto the left ventricle, which pumps it to the rest of the body.

In this lab, the students observed the rate and rhythm and how it fluctuates when an individual is relaxed, in a seated position, and after exercising. The Heart is a hollow muscular organ that is cone shaped and it is located in the mediastinum in between the lungs (The Heart, Slide 3 2016). The heart is separated into two main divisions, the pulmonary circuit and the systemic circuit. The pulmonary circuit helps carry blood to the lungs from the heart for gas exchange and it is located in the right side of the heart. In the pulmonary circuit the heart fills with blood in the right atrium then it passes through the right atrioventricular valve which then leads to the right ventricle. Once it is in the right ventricle, the right ventricle contracts which opens the pulmonary valves. After this blood flows from the pulmonary valve to the pulmonary trunk which then distributes it into the right and left pulmonary arteries that supply the lungs where it deposits oxygenated blood.

The system has two functions: to deliver oxygen and nutrients to cell and tissues & to remove carbon dioxide and other waste products from the cells and tissues. The base of the heart points toward the right shoulder, also it is about the size of your fist. The first layer of the heart wall is the epicardium. It is comprised of connective tissue that makes up the visceral pericardium. The middle layer is the myocardium, which is mostly cardiac muscle. The innermost layer is the endocardium. The heart has 4 chambers which allow is the pump correctly. Two atria chambers which receive blood and two ventricular chambers which discard of blood. There are two septa`s in the heart. The interventricular ( separates the 2 ventricles) and the interatrial (separates the 3 atria). Blood circulation is a thing because of the heart. Systemic circulation allows the blood to flow from the left side through the tissues and back to the heart entering on the right side. Pulmonary circulation allows the blood to flow from the right side to the lungs and back entering on the left side. A valve allows the blood to flow in one direction, it prevents backflow. There are 4 valves throughout the heart. They are the atrioventricular valve, bicuspid valve, semilunar valve, and the tricuspid valve. The two most important valves are the AV valve and the semilunar valve. The continuous circulation of blood through the body is vital for

muscular wall of the heart and forms a septum which separates the right and left side of the heart.

Cardiovascular system consists of the heart and it’s associated blood vessels. “Main functions of the cardiovascular system include the supply of oxygen and nutrients to all cellular tissues in the body while also removing metabolic wastes such as carbon dioxide” (Collins, 2013 p. 169). The heart is a four-chambered organ with two superior atria and two inferior ventricles. There is four valves located in the heart each function to prevent the backflow of blood into either atria or ventricular chambers. “The two valves located between the atria and ventricles are called atria-ventricular valves, while the two valves located between the pulmonary, aortic arteries and the ventricles are called semilunar valves” (Christensen & Kockrow, 2014 p.

Before understanding the physical theories behind the heart, it is useful to understand a little bit about the physiology of the heart. The heart is divided into four chambers: two atria on top and two ventricles on the bottom. The atrium and ventricles are separated by valves and the septum separates the right and left sides of the heart.3 Blood returns to the heart from the body through the veins, enters the right atrium and then flows to the

The heart has 4 hollow chambers. The upper chambers are called the left and right atria. The lower chambers are called the left and right ventricles. A wall of muscle called the septum separates the left and right atria and the left and right ventricles. The septum between the atria is called the interatrial septum and the septum between the ventricles is the interventricular septum. The atria are the receiving chambers because blood entre the heart through veins that open into these upper cavities. The ventricles are the discharging chambers from which blood is pumper from the heart into the arteries that exist from the ventricles.
