Human heart

Similar statistics are true for Europe, each year the disease causes over 4 million deaths in Europe and over 1.9 million deaths in the European Union. This makes it the major cause of death for both men and women in most countries of Europe (13). Heart failure and myocardial infarction result in cardiomyocyte death by apoptosis and/or necrosis. The cardiomyocytes’ limited capability to divide leads to the replacement of dead cells by proliferating fibroblast that migrate into the damaged area…

The Re-Enchantment of Everyday Life written by Thomas Moore describes enchantment as an atmosphere of emotion and fantasy that clinches to the heart, which can hinder it or send it to joy and day dreams. At moments, the heart can be overwhelmed by the beauty and imagination by an unforgettable feature in the world or a spirit or voice speaking of a thing, a place, or a person. The soul is our deepest self that includes our deepest emotions, our capacity for intimacy, and the resting place of…

The purpose of this experiment is to investigate the heart rate through the dive reflex Homeostasis is the body’s ability to maintain and balance its normal body function in varying conditions. The autonomic nervous system relates to the peripheral nervous system. Its objective is to sustain homeostasis of the visceral organs. In this investigation we will observe the mammalian diving reflex, which implicates the autonomic nervous system. In mammals, immersing the face in water initiates…

connections is parasympathetic activity, often conceptualized as the functioning of the vagus nerve and measured as respiratory sinus arrhythmia (RSA) or high-frequency heart rate variability (HF-HRV) at rest. The longest autonomic nerve in the human body, the vagus contributes to the innervation of the viscera, including the heart. Measures of cardiac vagal function like RSA have been used as a proxy for the parasympathetic nervous system’s ability to offset the effects of the sympathetic…

of the heart, blood vessels and approximately the 5 litres of the blood that the blood vessels transport. The cardiovascular system is powered by the body’s hardest working organ. The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from your body. The main structures of this system is the heart the blood vessels and blood. Delivery of oxygen and nutrients The pulmonary circuit carries blood to the lungs to be oxygenated and then back into e heart in…

For many centuries there is evidence that Music has been a big part of the human race’s culture. Music dates back as far as 250,000 years, and has been known for being all over the world. With the grand variety of music selection, each song has a different way of being perceived; for countless years psychologist have been trying to connection music with ones emotions. Music has been reported to induce a full range of human emotions. So how is it that organized sound and beats evoke such an…

Exercising can reduce the risk of health problems and even death later in life. From lifting weights to aerobic exercise, such as running and jumping rope, health improves all throughout the body. Exercising helps prevent many health risks such as heart disease, high blood pressure, stroke, cancer, diabetes, and gallbladder disease. While it helps to reduce the risks of…

About the size of a large fist, heart is made up of cardiac muscle, myocardium, with skeletal muscle-like striations. It has two upper atria & two lower ventricles separated vertically by septum, and four main valves with which the blood makes its directional flow into and out of the heart. Deoxygentated blood with which the blood flows into and out of the organ. Deoxygenated blood enters through the venae cava fills the right atrium (RA) and right ventricle (RV) through the tricuspid valve.…

The skeletal system is essential to the working of the human body. It provides protection and aids with movement, also. Approximately 20% of the human body’s mass is attributed to the skeletal system. This system is mostly comprised of bones, but there are other critical elements included as well. These elements are ligaments and cartilage. The human skeletal system is divided into two parts; the axial and appendicular skeletons. The axial skeleton is further divided, from superior to inferior…

average reclining heart rate is 69.1 beats per minute, and the average standing heart rate is 82.9 beats per minute. The standard deviation for reclining heart rate is 9.8, and the standard deviation for standing heart rate is 17.8. The average…
