Circulatory system

The cardiovascular system is a network composed of the heart and blood vessels to deliver oxygen and nutrients to all body tissues. However, there are similarities and differences between men and women, with respect to the structure and function of the cardiovascular system. According to a research, the size of the heart and major blood vessels are smaller in women than in men. Before puberty, there are no differences among sexes in relation to the size of the heart, but after puberty the…

The human body is composed of the heart, veins, and blood, the cardiovascular framework is the body’s framework that does the assignments of pumping and transporting blood, oxygen, supplements, and waste items, and different substances all throughout the body. The cardiovascular framework, nonetheless, wouldn’t have the capacity to conduct these capacities without assistance from what is once in a while alluded to as the body's most focused organ the heart. Currently, in our physical fitness…

The human heart contains a specialized conduction system through which it can create and transmit electrical impulses without any external neural input. The main components of the conduction system of the heart include the SA node, AV node, Bundle of His and the Purkinje fibers. The sinoatrial node (also known as SA node) is a natural pacemaker and is responsible for depolarization of the right and left atrium. This produces a P wave on the EKG reading which is normally 0.1 second and its normal…

The scientific term which is used to describe the temperature control in the body is called hypothalamus. Hypothalamus begins in your brain since your brain makes the choices for your body. This is very important because if you're too cold you can start shivering for long periods of time which can lead up to hypothermia. On the other hand, if you are too hot you and start to sweat a lot it can lead up to avoid disease. Here are the 3 different that your body can make in these tough situations.…

The cardiovascular system is the system in which it helps to circulate blood throughout your entire body. However, that's not its only function. It also helps to transport both oxygen and carbon dioxide, hormones, numerous cells, and also nutrients to the body's tissues and organs. This system consists of the heart, blood, and also blood vessels. The heart is a muscular structure that helps push the blood to flow throughout the body. It is composed of three layers the pericardium (around or…

To understand the collapse of the heart, first, the heart rate must be well understood. The heart rate in a fish is a combination of the intrinsic heart rate and the extrinsic modulations that act on it, such as excitatory adrenergic stimulations and inhibitory cholinergic stimulations (Nilsson, 1983). With the hypothesis that intrinsic heart rate might be the limiting factor, many have attempted to study the intrinsic cardiac functioning to further the understanding of the mechanical properties…

comprised of a huge amount of systems that work together. Two of these greatly important systems are the muscular and cardiovascular systems. These body systems are very heavily intertwined and cannot function without one another. If one fails, the other stops working soon after, and the loss of either of these systems would be utterly catastrophic to the smooth workings of the human body. The cardiovascular system could be described as being the life support system of the entire human body.…

Abstract Whens humans exercise, their oxygen supply needs to be increased in order to produce the energy needed to sustain this workload. Humans will use a variety of cardio-respiratory mechanisms in order to supply and meet the oxygen levels the body needs during exercise. In this study we wanted to see how different individuals respond to exercise, specifically how long they can work and how efficiently they work. We predicted that females who exercise will have a higher relative-VO2, higher…

results on its impact to health, life, and the human body. Many studies have been done regarding the effects of repetitive participation in vigorous physical activities and the changes in the human body, especially in respects to the cardiovascular system and the observed changes of myocardial structure and function (Baggish & Wood 2011). But what is the impact of these changes? It is well known that exercise benefits the heart which, as important as it is, is a muscle and thus can be…
