Sheep Heart Structure
In this examination, the outside and inner structures of a sheep's heart was analyzed and recognized by dismemberment. The heart is a muscle that pumps oxygenated blood and supplements all through the body. A sheep's heart has four chambers like most well evolved creatures. Two of those chambers are accepting chambers called the privilege and left chamber. The other two chambers are pumping chambers called the privilege and left ventricle.

The productivity in the cycle of blood relies on upon the successive withdrawal of the chambers and ventricles. At whatever point the chambers get this is known as the systolic stage and at whatever point the ventricles get this is known as the diastolic stage. These compressions guarantee the customary

    The heart is what some determine to be the most important organ in our bodies and one of the biggest contributors. It is one of the major organs that if we did not have, it would not be possible for us to live. The heart is about the size of a fist and is broken down into four chambers, the aorta, superior vena cava, pulmonary artery, and the coronary artery. The four chambers include the right and left atrium and the right and left ventricle. The heart is responsible for supplying oxygen and blood to the entire body. Blood passes through these four chambers and then exits and pumps into the rest of the body. The heart also has three layers of walls…

    The myocardium, commonly referred to as the heart, acts as a pump for transporting blood around the body via a collective system, known as the cardiovascular system. This system has various components; blood vessels; mainly arteries, veins and capillaries. The cardiovascular system has four main functions within the body. Firstly to transport dissolved oxygen, hormones, nutrients, salts, enzymes and urea to cells located around various places within the body, whilst at the same time eliminating any waste products such as carbon dioxide and water. Secondly, to protect the body from infection and blood loss. Thirdly, to distribute heat around the body to enable a healthy temperature of 37oc and finally to aid the body to maintain fluid balance. This ‘human pump’ can be regarded as two pumps. The fist sized organ contains two muscular chambers; the upper chamber; the atrium and the lower; the ventricle. The right side of the heart pumps deoxygenated blood from the veins to the lungs for oxygenation, whilst the left side pumps oxygenated blood from the lungs to the body. It is important to note that the two sides are separated by a septum. The blood flows through the heart twice within one cycle, this is known as ‘double circulation’.…

    The function of the heart is to pump blood throughout the body. The heart pumps blood containing oxygen from the lungs to body. It passes blood without oxygen back to the lungs for more oxygen. The heart has four chambers; the two upper chambers are called atriums, and the two lower chambers are called ventricles. The left atrium is located above the left ventricle, and they are separate by a valve called the mitral valve. The…

    I have decided to focus my essay on the biological cycles that occur inside organisms. The cardiac cycle is vital in all organisms with a heart, to pump blood round the body. There are phases of the cardiac cycle; systole (contraction) and diastole (relaxation). The heart consists of 4 chambers, 2 being the atria at the top of the heart and the other 2 being the ventricles at the bottom of the heart. Systole occurs separately in the atria and ventricles and diastole occurs simultaneously in all 4 chambers. The cardiac cycle is controlled by electrical waves that spread throughout the heart. The blood flows into the heart straight into the atria via the vena cava and pulmonary vein. A wave of electrical activity is firstly spread from the Sino-atrial node which spreads across both atria, this causes the atria to contract which forces blood down into the ventricles through the atrioventricular valves. The atrioventricular septum prevents the wave crossing the ventricles. The wave passes to the atrioventricular node where it is passed down the septum down specialised fibres known as the bundle of His. This occurs after a short delay to allow all the blood to flow from the atria to the ventricles. This wave passes down the bundle of His to the Apex of the heart where the Ventricles contract upward, pumping blood out of the ventricles into the pulmonary artery and aorta through the semilunar valves. Here the blood is then passed round the body where it then returns to the heart and the process repeats.…

    The heart lies in the thoratic cavity, organs associated with the heart are inferiorly, the hearts apex rested on the tendon of the diaphragm, superiorly, the great blood vessels, posteriorly the oesophagus, trachea and the left and right bronchus, laterally, the lungs and anteriorly the sternum and ribs. (Waugh& Grant 2014). The heart provides a constant blood circulation action and the blood vessels provide a network for the blood flow. The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body, ( www.le.ac.uk) the right side of the heart pumps blood to the lungs (pulmonary circulation) and the left side receives oxygenated blood and supplies it to the rest of the body (systemic circulation). There are three types of blood vessel, arteries, capilleries and veins. Blood is pumped from the heart through the arteries at high pressure which could damage the tissue so it needs to go through the capillaires which are smaller low pressure blood vessels that are responsilbe for providing oxygen to the tissues, they also absord excess carbon dioxide and then deliver the blood into the veins which then supply the blood back to the heart. The heart generates its own electrical impulses, it does not rely on any other external mechanisn to make it beat. A normal heart rate is 60-80 times per minute, factors which can decrease or…

    Have you ever done something you regretted later? For some people it's hard to control their feelings and emotions. In both the stories I read there are great examples.
