1. How does the heart change as it develops in a fetus? At first‚ the heart is just a tube. It grows so fast that it needs more space‚ so it bends and twists back‚ forming the familiar shape. During the next phase‚ the two atria are partly separate but there is just one big ventricle. The next phase begins when the two atria are completely separate and the ventricles are just beginning to separate. Finally‚ the ventricles separate completely and the heart is developed. 2. What is the largest vessel

pathology: Transmural: associated with atherosclerosis involving a major coronary artery. It can be subclassified into anterior‚ posterior‚ inferior‚ lateral or septal. Transmural infarcts extend through the whole thickness of the heart muscle and are usually a result of complete occlusion of the area’s blood supply.[13] In addition‚ on ECG‚ ST elevation and Q waves are seen. Subendocardial: involving a small area in the subendocardial wall of the left ventricle‚ ventricular septum‚ or papillary muscles

system and the respiratory system work closely together to ensure that organ tissues receive enough oxygen. Oxygen is required for cellular functions. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by the heart‚ which pumps the oxygenated blood from the lungs to the body. Additionally‚ the two body systems work together to remove carbon dioxide‚ which is a metabolic waste product. 3. Match each of the definitions in Column A with the appropriate

The term “heart failure” sounds as if the heart has already failed. This can increase a person’s anxiety especially in the aging population that is a targeted community for this disease assuming that the failure is equivalent to death.

Heart Dissection Sheep have a four-chambered heart‚ as do humans. By studying a sheep heart you can learn about your own heart at the same time. 1. Identify the right and left sides of the heart. Look closely and on one side you will see a diagonal line of blood vessels that divide the heart. The half that includes all of the apex of the heart is the left side. If you feel the heart‚ the left half will feel much firmer and more muscular than the right side. The left side of the heart has to

Dissecting a sheep’s heart can help to provide an active‚ firsthand learning experience that allows to illustrate what has been previously heard and read. The sheep heart and a human heart share the same function and purpose‚ which is to keep the body alive by continually circulating blood around the body. Like a human heart‚ a sheep’s heart contains two atria and two ventricles. These four chambers
