Some common congenital heart defects are illustrated in Figure 19. 6 Cardiovascular Disease: Review Questions and Answers. They normally include practice of the compression technique on a mannequin. It is marked by the presence of four openings that allow blood to move from the atria into the ventricles and from the ventricles into the pulmonary trunk and aorta.
Normally in an adult heart, the interatrial septum bears an oval-shaped depression known as the fossa ovalis, a remnant of an opening in the fetal heart known as the foramen ovale. Immediately superior and slightly medial to the opening of the inferior vena cava on the posterior surface of the atrium is the opening of the coronary sinus. 8 illustrates the differences in muscular thickness needed for each of the ventricles. In addition, echocardiography or cardiac magnetic resonance imaging may be employed. It is the contraction of the myocardium that pumps blood through the heart and into the major arteries. 11 shows papillary muscles and chordae tendineae attached to the tricuspid valve.

The coronary circulation consists of blood vessels that carry blood to and from the heart muscle cells. Chapter 11 the cardiovascular system workbook answers online. Offices & Departments.

Chapter 18: The Cardiovascular System: Blood - Anatomy & Physiology: BIO 161 / 162 - LibGuides at Community College of Allegheny County. Visit this site for audio examples of heart sounds. Heart: Cardiac Tamponade. Sample answer: The cardiovascular system needs to carry oxygen and nutrients to the body's cells and then remove carbon dioxide and other wastes from those cells.
The coronary sinus is a large, thin-walled vein on the posterior surface of the heart lying within the atrioventricular sulcus and emptying directly into the right atrium. Valve and septal disorders will trigger abnormal heart sounds. Detectable symptoms in an infant include difficulty breathing, poor appetite, trouble feeding, or failure to thrive. Heart failure, on the other hand, occurs when the pumping action of the heart is impaired so that tissues get some oxygen, but not enough. Sample answer: Angina and ischemic stroke both result in reduced or blocked blood flow to the body's tissues, which causes them to not receive adequate oxygen. In nonlife-threatening cases, it is better to monitor the condition than to risk heart surgery to repair and seal the opening. Chapter 11 the cardiovascular system workbook answers audio. Chapter 26 - Fluid, Electrolyte, and Acid-Base Balance. This process of blood circulation continues as long as the individual remains alive.
Auricles are relatively thin-walled structures that can fill with blood and empty into the atria or upper chambers of the heart. A transverse section through the heart slightly above the level of the atrioventricular septum reveals all four heart valves along the same plane (Figure 19. Chapter 11 the cardiovascular system workbook answers.yahoo. Despite the attention, development of artificial hearts to augment the severely limited supply of heart donors has proven less than satisfactory but will likely improve in the future. Identify two specific coronary artery diseases. It is substantially thicker than the interatrial septum, since the ventricles generate far greater pressure when they contract. Inside the pericardium, the surface features of the heart are visible, including the four chambers. This complex swirling pattern allows the heart to pump blood more effectively than a simple linear pattern would.
There are three dilations in the wall of the aorta just superior to the aortic semilunar valve. It arises from the inferior portion of the interventricular septum and crosses the interior space of the right ventricle to connect with the inferior papillary muscle. This would be equal to 5. The thin walls of capillaries allow these substances to flow easily across them. 2 Introduction to the Cardiovascular System: Review Questions and Answers. The foramen ovale allowed blood in the fetal heart to pass directly from the right atrium to the left atrium, allowing some blood to bypass the pulmonary circuit. In addition to causing chest pain, a heart attack may cause death or lead to heart arrhythmias, heart failure, or cardiac arrest. Using a stethoscope, the disruption to the normal flow of blood produces a heart murmur. Worldwide, cardiovascular diseases are the leading cause of mortality, causing about a third of all deaths annually. Sample answer: Oxygen, nutrients, and wastes. Chapter 20 - The Cardiovascular System: Blood Vessels and Circulation. Cardiomyocytes and pacemaker cells. The endocardium lines the chambers where the blood circulates and covers the heart valves.
The heart is a muscular organ in the chest that consists mainly of cardiac muscle and pumps blood through blood vessels by repeated, rhythmic contractions. However, as the myocardium of the ventricle contracts, so do the papillary muscles. External Carotid Artery. Describe the coronary circulation. These subspecialties include Certified Rhythm Analysis Technician (CRAT), Certified Cardiographic Technician (CCT), Registered Congenital Cardiac Sonographer (RCCS), Registered Cardiac Electrophysiology Specialist (RCES), Registered Cardiovascular Invasive Specialist (RCIS), Registered Cardiac Sonographer (RCS), Registered Vascular Specialist (RVS), and Registered Phlebology Sonographer (RPhS). Compare systemic circulation to pulmonary circulation. The marginal arteries supply blood to the superficial portions of the right ventricle. Angioplasty is a procedure in which the occlusion is mechanically widened with a balloon. Pacemaker cells make up only 1% of the cardiac muscle cells in the myocardium and conduct electrical impulses that cause the cardiomyocytes to contract rhythmically. It then gradually progresses throughout life. Link to video covering the circle of Willis. After successful completion of this examination, a physician becomes a board-certified cardiologist. Recall that, although both sides of the heart will pump the same amount of blood, the muscular layer is much thicker in the left ventricle compared to the right (see Figure 19.
On the posterior surface of the heart, the right coronary artery gives rise to the posterior interventricular artery, also known as the posterior descending artery. The membrane that directly surrounds the heart and defines the pericardial cavity is called the pericardium or pericardial sac. Until this anomaly between the sexes was discovered, many female patients suffering MIs were misdiagnosed and sent home. Celiac Trunk - Parts 1 & 2. Like all other cells, a cardiomyocyte requires a reliable supply of oxygen and nutrients, and a way to remove wastes, so it needs a dedicated, complex, and extensive coronary circulation.
Well-documented risk factors include smoking, family history, hypertension, obesity, diabetes, high alcohol consumption, lack of exercise, stress, and hyperlipidemia or high circulating levels of lipids in the blood. The word septum is derived from the Latin for "something that encloses;" in this case, a septum (plural = septa) refers to a wall or partition that divides the heart into chambers. A specialized catheter with an expandable tip is inserted into a superficial vessel, normally in the leg, and then directed to the site of the occlusion. How much mortality do cardiovascular diseases cause? CPR is generally performed until the patient regains spontaneous contraction or is declared dead by an experienced healthcare professional.
Stenosis is a condition in which the heart valves become rigid and may calcify over time. Do blood vessels carrying deoxygenated blood from the body back to the heart get increasingly larger or smaller? If one of the cusps of the valve is forced backward by the force of the blood, the condition is referred to as a prolapsed valve.
