Biol250 Lab Report Cardio Heart Essay

Inside the heart the four chambers were clearly defined and hollow. The wall on the left side of the heart was much thicker and firmer than the wall on the right side. The wall on the right side was very thin. The valves appeared stringy, stretchy and very long.

The hearts function as a double pump that serves two circulations. The pulmonary pump in the right side of heart is provided for the gas exchange in the body, and the systemic circulation in the left side provides the functional blood supply to all body tissues. The functional blood to the heart is provided by the coronary arteries. Right coronary artery supplies the heart through the posterior interventricular and marginal artery branches; and the left coronary artery supplies the heart via anterior interventricular artery and the circumflex artery. The myocardium is drained by great, small, and middle cardiac veins which

The fetal pig heart and the sheep heart were very similar in structure. They both consist of two atria and two ventricles. The biggest difference noted between the fetal pig and the sheep hearts were the size. The sheep heart was larger than the pig, although the pig heart seemed to have thicker myocardial muscles.

The heart pumps the blood around the body through the blood vessels which is made of mostly veins and capillaries. The blood carries the dissolved oxygen around the bodily

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

The heart is basically a pump that has to circulate the blood around the body delivering oxygenated blood to our organs and then returning deoxygenated blood to our lungs. There are four chambers in the heart, two atria and two ventricles. There are four main valves, mitral, aortic, tricuspid and pulmonary7b.

13. During the sheep heart dissection, you were asked initially to identify the right and left ventricles without cutting into the heart. During this procedure, what differences did you observe between the two chambers? The left ventricle is think and solid as it pumps blood through the body, the right walls are thinner

Oxygen and nutrients the body requires for function are pumped around this complex network of blood vessels by the heart. At roughly the size of a human fist, the heart is a four-chambered muscle and performs two functions of circulation simultaneously and continuously. Systemic and pulmonary circulation. The heart is made up from three separate layers of cardiac tissue; the outer layer called the pericardium, which is a double sac-like outer covering with serous fluid inside to keep the middle layer, the myocardium from adhering to the outer layer. This middle layer of the heart is the heart muscle which is thicker on the left side, to aid with the pressure needed to sustain systemic circulation. The inner layer of the heart is the endocardium. It’s lining is smooth to help prevent the blood which circulates around the inside of the heart from clotting. The heart is the human body’s in-built pacemaker, and the electrical signals sent through the it cause the heart to contract and relax. This process is triggered by the autonomic nervous system and the contraction and relaxing cycle is

The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).

The left side of the heart, has the left atrium and ventricle that takes in oxygenated blood from the lungs and pumps it out of the aorta.

Now consider all the parts you've found and how the blood flows through them. Draw a diagram of the heart and use red and blue arrows to show the flow of blood:

The students will apply their knowledge about the heart to a design—in which the heart will be modeled as a pump.

I was able to observe each of the atriums and ventricles, along with the aorta and valves. I compared the left and the right side, seeing how they are different in size along with different valves and muscles. With looking at the heart I labeled all different parts those including, right atrium, right ventricle, left atrium, left ventricle, tricuspid valve, aorta, aortic valve, papillary muscle, septum, and bicuspid valve.

16. The following statements refer to your observation of one or more of the vessel types observed in the microcirculation in the
