Heart

Heart Smart is a voluntary non for profit organization that is working to bring awareness towards congestive heart failure also known as CHF or heart failure. CHF is a chronic condition in which the heart does not pump blood as well as it should. Heart failure can occur if the heart cannot pump (systolic) or fill (diastolic) adequately. Symptoms include shortness of breath, fatigue, swollen legs, and rapid heartbeat. Treatments can include eating less salt, limiting fluid intake, and taking prescription

cardiovascular system, also known as the circulatory system is made up of the heart, the blood vessels and the blood. It is a double circulatory system because it is made up of two different circuits; the pulmonary circuit which is between the heart and lungs and the systemic circuit which is between the heart and the other organs around transferring the nutrients and waste in and out of the body. This means the blood passes through the heart twice during the cardiac cycle. These images have been

The heart and the brain are both uniquely fascinating organs in the human body. People probably believe the heart and the brain are very different from each other. They probably think the brain is what we use to think, make decisions, do well on English papers, and how we know how to do our jobs. They probably think the heart is how we pump blood through the body, what the doctor listens to during patient checkups, or that we have had a meal that just didn’t agree with us. These do seem like quite

What anatomical structure of the heart produces the "lub" and "dub" sounds? What are Korotkoff sounds? How are Korotkoff sounds different from the "lub" "dub" sounds? The heart is connected to the rest of the cardiovascular system through several large arteries and veins. The right atrium receives blood through the superior and inferior vena cava, the two largest veins of the body, while the left ventricle receives blood through the pulmonary veins. The right ventricle pumps blood through the pulmonary

Anatomy of the heart Name: Rita Attah Tutor: Mark Drummond College: North Herts College Introduction The heart The heart is a muscular organ found in the thoracic cavity between the lungs. The heart is protected by the rib cage. It is also surrounded by a membrane called the pericardium. This membrane consists of a thin film of fluid to prevent the heart from friction. The heart consists of double pumps. Each pump is made of two chambers. The upper muscular chamber is known as atrium and

The human heart is a myogenic muscle 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 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

The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries (which provide oxygen and nutrients to body tissues by transporting the blood throughout the body). The heart is located in the thoracic cavity medial to the lungs and posterior to the sternum. Pericardium The heart sits within a fluid-filled cavity called

isolated organs and allow them to perform as they do inside the body (Silverthorn, 2013).The frog heart beats slowly and therefore allows us to easily observe the mechanical activity of the cardiac cycle (Courtice, 1989). The heart is made up of cardiac muscle. Compared to skeletal muscle, cardiac muscle exhibits a few differences such as rhythmicity. The frog heart is different to the mammalian heart in that it has three chambers instead of four (Sherwood et al, 2013). The pacemaker cells are located

Function of the Heart The heart is the pump that propels the blood around the body providing essential nutrition to cells and tissues. The heart is the most important muscle in the human body. It is about the size of the owner's fist. The heart is the pump that drives the whole circulatory system. It receives and propels blood, rhythmically contracting with every heartbeat and forcing the blood through a system of arteries veins and capillaries, where it eventually reaches cells and tissues. Blood
