Abstract. There are seven stages of the cardiac cycle, split into systole and diastole. The conduction system consists of the SA node, the AV node, the Bundle of His and the Purkinje fibres. The cardiac cycle can be used to explain the different heart sounds heard (closing of valves) and the changes seen in an ECG. Core.

- How The Heart Valves Work
The heart is located under the rib cage -- 2/3 of it is to the left of your breastbone (sternum) -- and between your lungs and above the diaphragm.The heart is about the size of a closed fist, weighs about 10.5 ounces, and is somewhat cone-shaped. It is covered by a sack termed the pericardium or pericardialsack.The normal heart anatomy consists of a four-chambered, hollow organ.It is divided into the left and right sides by a muscular wall called the septum.Normal heart anatomy and physiology need the atria and ventricles to work sequentially, contracting and relaxing to pump blood out of the heart and then to let the chambers refill. When blood leaves each chamber of the heart, it passes through a valve that is designed to prevent the backflow of blood. There are four heart valves within the heart: 1...
The heart valves work the same way as one-way valves in the plumbing of your home. They prevent blood from flowing in the wrong direction.Each valve has a set of flaps, called leaflets or cusps.The mitral valve has two leaflets; the others have three.The leaflets are attached to and supported by a ring of tough, fibrous tissue called the annulus.- Heart anatomy. The heart has five surfaces: base (posterior), diaphragmatic (inferior), sternocostal (anterior), and left and right pulmonary surfaces. It also has several margins: right, left, superior, and inferior
- Heart valves. Heart valves separate atria from ventricles, and ventricles from great vessels. The valves incorporate two or three leaflets (cusps) around the atrioventricular orifices and the roots of great vessels.
- Blood flow through the heart. The blood flow through the heart is quite logical. It happens with the heart cycle, which consists of the periodical contraction and relaxation of the atrial and ventricular myocardium (heart muscle tissue).
- Coronary circulation. The heart must also be supplied with oxygenated blood. This is done by the two coronary arteries: left and right. Heart muscles work constantly (thank goodness!)
Jun 11, 2024 · The heart is the pump that moves blood around your body. It has four main parts: two upper chambers called atria and two lower chambers called ventricles. These parts work together to get oxygen-rich blood to your body and oxygen-poor blood back to your heart.
Oct 30, 2023 · The Wiggers diagram highlights the relationship between pressure and volume over time, along with the electrical activity of the heart. The diagram uses the left chambers of the heart to demonstrate: Aortic pressure; Atrial pressure; Ventricular pressure; Ventricular volume; Electrocardiogram (ECG) Phonocardiogram (heart sounds)
Nov 10, 2024 · Last updated on November 10, 2024. The heart is a muscular organ that pumps blood throughout the body via the circulatory system. It is approximately the size of a fist and consists of four chambers: two atria and two ventricles. The heart is composed of specialized muscle tissue, known as myocardium, and is encased within a double-layered ...
