Pig Heart Lab

671 Words3 Pages

Purpose
The purpose of the lab is to dissect a pig heart in order to identify all of the parts of main chambers, valves, and vessels. To able to know the circulation the blood through the heart to the lungs and identify each section of the pig heart. The pig heart has four chambers which it is two atria and two ventricles. They both pump the blood and give the body what it needs. The heart has four valves which help the blood flow. There are 5 main types of blood vessels that enter and leave the heart.

Hypothesis
If the heart is pumping the blood through the body, then it is connect to the vascular system. The vascular is also called cardiovascular systems that contains blood vessels and lymph through the body. It helps circulate the blood …show more content…

The data have supported the hypothesis because it showed that vessels is connect to the heart. The right atrium and left atrium are part of the chambers in the heart. Right atrium received deoxygenated blood and pumps it into right ventricle that send to the lung so it can oxygenated. But, left atrium pumping oxygenated blood to the tissues of the body. Right and left ventricles are part of the chambers. Right ventricle pumping the deoxygenated blood through the pulmonary valve and artery to the lungs. But left ventricle pumping oxygenated blood through the aorta and valve into the circulation. The aorta is main artery of the body and it is top of heart which carries the blood away from the body. The coronary artery supply oxygen-rich blood to the heart muscles. Pulmonary veins are large vessels that carrying oxygenated blood from the lungs to the left atrium which it is draining. Pulmonary trunk is a vessel that appear from the right ventricle and proceed deoxygenated blood from the heart to the lungs. Pulmonary arteries is from right ventricles of the heart to carry blood to the lungs for oxygenation. Semilunar valve of pulmonary artery located between the right ventricle and the pulmonary artery do it can pump the blood into the arteries, but will prevent blood that go opposite. Semilunar valve of aorta located between the left ventricle and the aorta. Bicuspid (mitral) valve loved between the left atrium and left ventricle which only let blood flow this way. Tricuspid valve located the right atrium and right ventricle which let the blood flow into ventricles. Chordae tendineae looked like strings in the heart. Intrerventricular septum is the wall that separating the lower chambers. The data show the location of each part of the heart that help pump the blood to benefit the body and remove the

    Pathophysiology The present of a patent foramen ovale is required to permit blood flow across the septum into the left atrium, the patent duct arteriosus allows blood to flow to the pulmonary artery into the lungs. VSD allows a modest amount of blood to enter the right ventricle &pulmonary artery. Thus pulmonary blood flow is diminished.

    The Pintails heart is like a mammals consisting of four chambers, two ventricles and two atria. The left ventricle pumps blood to all major organs in the body and throughout the rest, only excluding the lungs. This causes the left ventricle to be larger and more muscular. The lungs are fed blood from the right ventricle, which is the only the only function of that ventricle. The oxygenated blood coming from the lungs is fully separated from the oxygenated blood coming from other parts of the body.

    Liver – the human liver has four lobes: right, left, caudate and quadrate. The fetal pig liver has five lobes: right lateral, right central, left central, left lateral, and caudate. Intestines – there is a significant difference in the structure of the fetal pig colon compared to the human colon. The pig colon is spiral. (See p. 45 of the FPDG.)

    Veins transport blood to the heart and lungs at low pressure after receiving it from the capillaries. Valves inside the veins keep blood moving in one direction. The human body's arterial system branches out from one main artery, the dorsal aorta. Like veins, arteries have three layers: an outer layer of tissue, an inner layer of epithelial cells and a layer of muscle in between.

  • Atrial Septal Defect Essay

    Normally, low-oxygen blood entering the right side of the heart stays on the right side, and subsequently oxygen-rich blood stays on the left side of the heart, where it is then pumped to the body and tissues. When a defect or "hole" is present between the atria (or upper chambers of heart), some oxygen-rich blood leaks back to the right side of the heart. It then goes back to the lungs even though it is already rich enough in oxygen. Because of this, there is a significant increase in the blood that goes to the lungs overall. Atrial septal defects can

    Heart, lungs and the Rest of You By: Olivia Abel 1.Explain how the blood flows throughout your lungs, heart and the rest of your body.   Heart: Your left and right side of your heart work together to pump blood to and throughout your body which is separated by muscular tissue called the septum. In the right side blood enters through two large vein which are the inferior and superior vena cava, emptying poor oxygen blood from the body to the right reticulum. When the left side enters from the pulmonary veins and empties oxygen rich blood from the lungs into the aorta going throughout the body.

  • Diastolic Heart Failure

    Systolic and Diastolic Heart Failure Heart failure occurs when the heart cannot pump enough blood for the body due to a weakened or damaged heart. The heart 's pumping action moves oxygen-rich blood as it travels from the lungs to the left atrium, then on to the left ventricle, which pumps it to the rest of the body. The left ventricle supplies most of the heart 's pumping power, so it 's larger than the other chambers and essential for normal function. (American Heart Association). In left-sided or left ventricular heart failure, the left side of the heart must work harder to pump the same amount of blood.

    Because of this inability to contract effectively, the rest of the vital organs receive inadequate amount of blood resulting to inadequate tissue perfusion. There are two types of left-sided HF; systolic and diastolic failure. Systolic failure happens when the left ventricle doesn’t have the enough energy to pump normally the blood to the general circulation. As for diastolic failure, the left ventricle loses the ability to fill itself with blood during resting period resulting to inadequate amount of blood to be pumped out to the circulation (Weinrauch, 2008). The diastolic dysfunction will eventually lead to right-sided heart failure.

  • Summary: Skeletal Muscles

    1789 Words  | 8 Pages

    The cardiac cycle is the coordination of the filling and exhausting of blood by electrical signals that cause the heart muscles to contract and unwind. The contraction of the heart is directed by a nerve drive that goes from the SA node to AV node to AV group to Purkinje fibers to the myocardium. Amid the cardiac cycle, the heart contracts by means of systole, pushing blood out of the heart, and unwinds through diastole, filling the heart with blood. Cardiomyocytes, or cardiac cells, are striated and are in charge of the pumping of the heart; they are the main muscle cells with intercalated plates. The heart's inner pacemaker controls and times the thumping of the heart by means of electrical signals.

    Vesalius had observed, by dissection, that there were no pores in the septum of the heart. This meant that direct transfer of blood was not possible. Harvey’s explanation for how blood was transferred from the right ventricle to the left ventricle was that it went through the lungs via the pulmonary arteries and returned through veins to the left auricle, and subsequently to the left ventricle. Once again this description was a simplified explanation of flow in line with his observations and those of Vesalius and
