Study with Quizlet and memorize flashcards containing terms like What side of the heart pumps blood through the systemic circulation?, Pathological death of cells or tissues is termed ___, The atria of the heart are separated by a thin muscle wall called the interatrial ___ and more.
- 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!)

Sometimes, your heart’s teamwork gets disrupted. Some disruptions begin before we’re born and cause congenital heart disease. Other problems arise throughout our lives, especially as we get older. Because your chambers are so important to your heart’s structure, many heart conditions and disorders involve them. The list below reviews some problems ...
Problems with your heart chambers or any part of your heart are often easy to miss. You might not have symptoms or notice anything is wrong until the problem has gotten worse. Heart disease is called a “silent killer” because it can sneak up on you. That’s why it’s important to go for physical exams and talk with your healthcare provider about your...
Depending on what’s wrong, your healthcare provider may first recommend some simple lifestyle changes. For example, consuming less caffeine can reduce some arrhythmia symptoms. In other cases, you may need medication. For instance, if you have atrial fibrillation, you may need medications to control your heart rate or manage underlying thyroid dise...

- Epicardium. Epicardium (epi-cardium) is the outer layer of the heart wall. It is also known as visceral pericardium as it forms the inner layer of the pericardium.
- Myocardium. Myocardium (myo-cardium) is the middle layer of the heart wall. It is composed of cardiac muscle fibers, which enable heart contractions. The myocardium is the thickest layer of the heart wall, with its thickness varying in different parts of the heart.
- Endocardium. Endocardium (endo-cardium) is the thin inner layer of the heart wall. This layer lines the inner heart chambers, covers heart valves, and is continuous with the endothelium of large blood vessels.
Nov 3, 2023 · The myocardium is functionally the main constituent of the heart and the thickest layer of all three heart layers. It is a muscle layer that enables heart contractions. Histologically, the myocardium is comprised of cardiomyocytes .
Nov 10, 2024 · These chambers are separated by valves and muscular septa, which direct blood flow and maintain efficient circulation. The heart wall is composed of three layers: the epicardium, myocardium, and endocardium. External Anatomy of the Heart. Apex and Base: The apex of the heart is the pointed lower tip that is oriented downward and to the left. It ...

Oct 4, 2019 · Last Updated: October 4, 2019. Cardiac Muscle Definition. Cardiac muscle, also known as heart muscle, is the layer of muscle tissue which lies between the endocardium and epicardium. These inner and outer layers of the heart, respectively, surround the cardiac muscle tissue and separate it from the blood and other organs.
