The primary responsibility of the heart is to pump blood throughout the circulatory system. As the center of the circulatory system, the heart is an essential organ for maintaining the overall functioning of the body. The cardiovascular system consists of many veins and blood vessels which ensure that all parts of the body are provided with an adequate amount of oxygen and nutrients to function efficiently. Without a sufficient supply of oxygen, any bodily function would fail, causing organ damage or organ death. Components of the heart Fully understanding the heart’s vital function in the body entails the need to first understand its anatomy. As a busy and hardworking organ, the heart needs to closely monitor all of its components to ensure proper functioning. Even a minor cardiac dysfunction may result in significant functional challenges in the total body function of an affected individual. Located at the center of the chest and in the thoracic cavity, the heart can be divided into four parts that are otherwise known as chambers, each of which contains several valves. Two of these chambers, which are called atria, are located in the upper portion of the heart and receive oxygen-free blood. The valves that separate these chambers are called atrioventricular valves, which are composed of the tricuspid valve on the left and the mitral valve on the right.

Similar to the atria, the ventricular chambers are also separated by valves called semilunar valves. These valves may be further divided into the pulmonary and aortic valves. The heart is also composed of a protective layer that has three parts, which include the outer layer known as the epicardium, the middle layer known as the myocardium, and the innermost layer known as the endocardium. Both the outer and inner layers of the heart are thin; whereas the middle layer, makes up most of the heart and is comrpised of cardiac muscle fibers.

1 answers

Adithya Dev A 4 years, 6 months ago (10643926)

Psychology as a discipline seeks to develop an idea on how our mind works and how different behaviours lead to different mental and how they interact with our environment. Different psychologists use different ways to study about mind and its nature. When some study the discipline in scientific and objective manner, others do so from the point of view of the observer ie, in a subjective manner. The discipline has two parallel streams - use of biological and physical sciences to study human behaviour and then, study of human behaviour in sociocultural contexts.

iodine is a type of mineral that’s naturally found in the earth’s soil and ocean waters. Many salt water and plant-based foods contain iodine, and this mineral is most-widely available in iodized salt.

Iodine is considered an essential mineral for our bodies. It’s particularly important during pregnancy, and exposure in the womb may even help prevent certain health conditions later in life.
