Human heart

The human heart is the one organ that powers the entire body. Without it we wouldn’t be able to do the simplest functions. Simple things like talking, walking, and even breathing relies on the heart pumping. Pumping blood into all the different parts of the body allows the circulatory system to supply oxygen and nutrients to the tissues and remove carbon dioxide and other wastes. The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. There are

The human heart is slightly bigger than the size of ones fist. It is situated at a very safe place which is between the cage bones, i.e., in the center of the chest. Usually it is slightly on the left side of the chest but in rare cases, it can be found on the right side. Heart is responsible for the blood flow to every single part of the body by constant contraction and relaxation of cardiac muscles. This is the reason why we hear rhythmic beats all the time. Heart pumps the pure blood to the different

The human heart is a myogenic muscle which is vital to human life, as it is the muscle which deals with the pumping of oxygenated and deoxygenated blood throughout the entire body. Due to the importance of the heart an understanding of this complex muscle is necessary. Therefore, today I hope to discuss the embryology of the heart. The formation of the heart begins during the third week of development, the embryo undergoes gastrulation in the embryonic plate resulting in the formation of three germ

Due to importance of the heart an understanding of this complex muscle is necessary. Therefore, today I hope to discuss the embryology of the heart. The formation of the heart begins during the third week of development, the embryo undergoes gastrulation in the embryonic plate producing three germ layers (ectoderm, mesoderm and

From my high school Human Anatomy and Physiology class, I vaguely remember the structure of the human heart. The human heart is fairly simple at a non-cellular level. Your heart contains a right and left atrium, and directly under those, a left and right ventricle. These are the four chambers of the human heart. Your heart also has two main exiting arteries: the pulmonary trunk which exits from the right ventricle and the aorta which exists from the left ventricle. The pulmonary trunk carries “dirty”

The heart is one of the most important organs in the human body. It circulates blood to the rest of the body. The heart is made up of four chambers, of the two chambers, the two upper chambers (known as the atria) and two lower chambers (known as ventricles). The heart is made up of three levels: the myocardium, the endocardium, and the epicardium. The myocardium is the muscular middle layer of the heart. It contains striated cardiac tissue and the myocardium is in charge of pumping blood and the

Cardiology The human heart has a special characteristic, it has its own electrical impulse, which allows it to beat normally outside of the human body as long as it has sufficient oxygen levels. The term cardiology refers to the medical branch which focuses on disease and irregularities of the heart. A cardiologist focuses on the individual area of the body that is the heart and these doctors focus on preventing and treating illnesses of the whole heart or single vessels or arteries. Technology

In order to understand defects of the human heart, it is important to first understand its development. Initially, the fetal heart is a simple tube, consisting of just three layers and three specific areas. These primitive layers later develop into the myocardium and epicardium of the heart. The areas – cranial (head) end, caudal (tail) end, and bulbus cordis – eventually form the aorta and ventricles. Around the third week of pregnancy, the fetal heartbeat can be seen as a flicker on the ultrasound

The heart of a human is a vital internal organ consists of cardiac muscles, which pump and circulate blood contained oxygen, hormones and necessary nutrients throughout the body. Heart rate is the amount of poundings of the heart per unit of time, usually in beats per minute (bpm). The heart rate can change due to the body 's physical needs including oxygen absorption and carbon dioxide excretion. The normal resting heart rate of an adult human ranges from 60 to100 beats per minute. During

The human heart is one of the most important organs that are in the human body. This organ is necessary for people to be able to live. There are a couple of functions that the heart does that makes it so important. It is responsible for circulating blood in the body, as well as ensuring that the blood pressure is kept at a constant rate. Your heart can be found in the center of your chest. The human heart is divided into four quarters by a strong muscle. The upper portion of the heart is known as
