Vena Cava Blood Flow
693 wordsEXPLORATION AND DISSECTION OF A MAMMALIAN HEART In this experiment, we obtained a fresh heart and dissected it to examine and observe the different parts of the heart, as well as studying how they function and work Problem: How can we study the heart through dissection? The most basic function of the circulatory system is to move the blood. The organ that provides the force to push the blood through the vessels is the heart. The mammalian heart is composed of four chambers to which large blood v...

White Blood Cells Parts Of The Body
1,025 wordsCirculatory System is the combined function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products. The circulatory system increases the flow of blood to meet increased energy demands during exercise and regulates body temperature. Also, when foreign substances or organisms invade the body, the circulatory system quickly sends disease-fighting elements of the immune system, such as white blood cells and ant...

Vena Cava Blood Vessels
1,407 wordsThe Circulatory System The circulatory system in anatomy and physiology is the course taken by the blood through the arteries, capillaries, and veins and back to the heart. In humans and the higher vertebrates, the heart is made up of four chambers the right and left auricles, or atria, and the right and left ventricles. The right side of the heart pumps oxygen-poor blood from the cells of the body back to the lungs for new oxygen; the left side of the heart receives blood rich in oxygen from th...

Pulmonary Artery Vena Cava
1,945 wordsHeartthe human heart is a specialized, four-chambered muscle that maintains BLOOD flow in the CIRCULATORYSYSTEM. Located in the thorax, it lies left of the bodys midline, above and in contact with the diaphragm. It is situated immediately behind the breastbone, or sternum, and between the lungs, with its apex tilted to the body cavity's left side. In most people the apex can be felt during each heart contraction. At rest, the heart pumps about 59 cc (2 oz) of blood per beat and 5 l (5 qt) per mi...

Divided Into Four Pulmonary Artery
3,525 wordsTheHheart Biology Histology The Human Heart. Abstract: Dorlands Illustrated Medical Dictionary defines the heart as the viscus of cardiac muscle that maintains the circulation of the blood. It is divided into four cavities; two atria and two ventricles. The left atrium receives oxygenated blood from the lungs. From there the blood passes to the left ventricle, which forces it via the aorta, through the arteries to supply the tissues of the body. The right atrium receives the blood after it has p...

Tricyclic Antidepressants Coronary Artery
4,629 wordsCardiac Location and Structures The heart is the driving force of the circulatory system, contracting about 70 times / minute to pump an adequate volume of blood with sufficient pressure to perfuse all body organs and tissues. The muscular organ, about the size of a clenched fist, weights from 300 to 400 g. It is located within the mediastinum of the thoracic cavity, above the diaphragm and between the lungs. This location subjects the heart? s activity to influence from all pressure variances d...

Red Blood Cells Pulmonary Artery
6,589 wordsForwards and backwards to the right and are at the same level of the fifth to eight dorsal vertebrae. The apex of the heart points downwards and forwards to the left and corresponds to the space between the fifth and sixth ribs. However, in thin people, the hearts apex may be pointing more downwards than to the left. Its atrial border corresponds to a line drawn across the sternum on a level with the upper border of the third costal cartilage. Its apex corresponds to a line drawn across the lowe...
