Heart diagram class 10 easy

The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, as well as assists in the removal of metabolic wastes. In humans, the heart is located between the lungs, in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria; and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart.] Fish, in contrast, have two chambers, an atrium and a ventricle, while reptiles have three chambers.In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium. The right heart consists of two chambers, the right atrium and the right ventricle, separated by a valve, the tricuspid valve. The left heart has two chambers: the left atrium, and the left ventricle, separated by the mitral valve.The heart wall is made up of three layers: the inner endocardium, middle myocardium and outer epicardium. These are surrounded by a double-membraned sac called the pericardium. The heart functions as a pump in the circulatory system to provide a continuous flow of bloo...

Heart is a vital organ that you cannot live without. The function of heart is quite complex, but you can understand things better through the heart diagram labeled below. It provides information about different chambers of the heart and valves that help transfer blood from one part of your heart to another. Keep reading to learn more about how your heart works. Four Chambers of the Heart and Blood Circulation The shape of the human heart is like an upside-down pear, weighing between 7-15 ounces, and is little larger than the size of the fist. It is located between the lungs, in the middle of the chest, behind and slightly to the left of the breast bone. The heart, one of the most significant organs in the human body, is a muscular pump, which pumps blood throughout the body. It beats approximately 72 times per minute, and pumps oxygenated blood to different parts of the body. Atria and Ventricles There are four chambers in your heart that are left atrium, right atrium, left ventricle, and right ventricle. • The upper chambers of your heart are atria, whereas the lower chambers are ventricles. • Deoxygenated blood enters your heart through the right atria from where the blood moves into the right ventricle first and then to the lungs through the pulmonary artery. Your left atrium receives oxygenated blood from the lungs, which is then pumped into the left ventricle from where it moves into the aorta and then to the different parts of your body. Valves to Ensure Unidirection...

Human Heart Human Heart is a muscular organ located in the chest between the lungs. It is about the size of a fist and is responsible for pumping blood throughout the body. It has four chambers – The right atrium, Right ventricle, Left atrium and Left ventricle. Human Heart Diagram Human Heart Diagram Description of Aorta Aorta is the main blood vessel of the body that carries oxygenated blood from the heart to the rest of the body. Also Check- Describe the Flow of Blood through the Heart of Human Beings Superior Vena Cava Superior Vena Cava is a large vein that carries deoxygenated blood from the upper body back to the heart. Inferior Vena Cava Inferior Vena Cava is the large vein that carries deoxygenated blood from the lower body back to the heart. Pulmonary artery Pulmonary Artery is the Pulmonary veins Pulmonary Vein is the blood vessel that carries oxygenated blood from the lungs back to the left atrium. ALso Check- Types and Functions of Blood Vessels Left atrium Left Atrium is the upper chamber on the left side of the heart that receives oxygenated blood from the pulmonary veins and pumps it into the left ventricle. Also Check- Transportation in Human Beings Mitral Valve (Bicuspid Valve) Aortic Valve Aortic Valve is the valve located between the left ventricle and the aorta. The aortic valve controls the flow of blood from the left ventricle into the Aorta. Tricuspid Valve Tricuspid Valve is located between the right atrium and the right ventricle. It controls the ...

Cardiac Cycle The human heart is a muscular organ that is about the size of a fist. It pumps blood through a set of connections between arteries and veins, known as the cardiovascular system. It involves systemic and pulmonary circulation. Table of Contents • • • • • Cardiac Cycle Definition “Cardiac cycle refers to the sequence of events that take place when the heart beats.” What is Cardiac Cycle? The cardiac cycle attributes to a comprehensive heartbeat from its production to the commencement of the next beat. It comprises diastole, the systole, and the intervening pause. The occurrence of a cardiac cycle is illustrated by a heart rate, which is naturally indicated as beats per minute. A healthy human heart beats 72 times per minute which states that there are 72 cardiac cycles per minute. The cardiac cycle involves a complete contraction and relaxation of both the atria and ventricles and the cycle last approximately 0.8 seconds. Also Refer: Cardiac Cycle Phases Following are the different phases that occur in a cardiac cycle: Atrial Diastole: In this stage, chambers of the heart are calmed. That is when the aortic valve and pulmonary artery closes and atrioventricular valves open, thus causing chambers of the heart to relax. Atrial Systole: At this phase, Isovolumic Contraction: At this stage, ventricles begin to contract. The atrioventricular valves, valve, and pulmonary artery valves close, but there won’t be any transformation in volume. Ventricular Ejection: ...
