Cardiovascular System: The Heart Purpose Explain why you did this exercise. Where there any safety precautions you needed to follow? If so‚ what were they? The safety precautions in this exercise were to wear goggles and gloves due to being exposed to chemicals and dissection of the sheep and cat heart. Appropriate work space was also required. Exercise 1: Microscopic
Premium Heart
The left atrium receives oxygenated blood from the lungs via four pulmonary veins. The left ventricle is the largest and most muscular chamber. It receives oxygenated blood from the lungs via the left atrium and pumps blood into the systemic circulation via the aorta. Valves: There are four valves in the heart two atrioventricular (AV) valves – the tricuspid and the mitral – that lie between the atria and ventricles. The tricuspid is located on the right side of the heart. The bicuspid or

Hint: There are multiple correct answers. Choose all that apply. 1.*The primary function of the circulatory system is to transport nutrients‚ gases‚ hormones and wastes throughout the body. A. True B.False **Ans.A 2. *The Interventricular septum the heart prevents blood from flowing from the right to the left sides of the heart. A. True B.False **Ans.A 3. The valves are flaps that are located on each end of the two ventricles of the heart. A. They prevent blood from flowing

to the use of thrombolytic therapy that must be taken in to account are intracranial bleeding‚ inability to start thrombosis in Myocardial Infarction flow in patients‚ and high percentage of recurrent ischemia and reocclusion. Primary percutaneous coronary intervention (PCI) has become known as the ideal reperfusion strategy. The proposed research will be a randomized controlled clinical trial study that will explore the roles of Fibrinolytic therapy vs. PCI in patients whom have received

Health Promotion Plan for African American Adults at Risk for Coronary Heart Disease Community Nursing: NUR 3634 Abstract Coronary heart disease affects a disproportionate amount of African Americans (CDC‚ 2010a)‚ yet there are modifiable risk factors that can reduce the risk of this disease. These modifiable risk factors include high blood pressure and high cholesterol. This health promotion plan involves a community-based strategy that targets African Americans by offering primary and

Human Anatomy and Physiology 260 - Midterm 1 Cardiovascular Anatomy Arteries: • Carry Blood from the heart to the tissues • Gradually decreasing in size of vessels o Arteries - Transportation of red blood cells away from the heart o Arterioles - Smaller‚ lead from the arteries to the capollaries o Capillaries - Gas exchange (tissue level) • 3 layers of wall: o 1. Tunica Adventitia (Tough outer layer) o 2. Turnica media (Middle smooth muscular layer‚ changes the diameter of the blood
Premium Heart Blood Lymphatic system
How things flow through the heart: • blood drains into the right atrium through the superior vena cava‚ inferior vena cava‚ and the coronary sinus (drains the heart muscle itself)→Right Ventricle→pulmonary semilunar valves→lungs→pulmonary veins→left atrium→bicuspid valve→left ventricle→aortic semilunar valve→systemic circuit. What the valves do: • Prevent backflow into the atria and ventricles‚ ensuring that blood only flows one way through the heart. what vessels bring blood to the heart and

the measure of the heart beat and the blood pressure is a measure of the pressure of the blood against the walls of a blood vessel. 6. The pulmonary circuit circulates blood through the lungs. The systemic circuit to the body tissues‚ and the coronary circulation circulates blood through the heart. 7. 5 cardiovascular disorders are: Hypertension is when the blood moves through the arteries at a higher pressure than normal. Hypertension can cause heart attack‚ stroke or even kidney failure Atherosclerosis
