Anatomy and Physiology Basics Cardiovascular System
Overview of Heart’s primary job • http://www.nlm.nih.gov/medlineplus/ency/anatomyvideos/000012.htm
What do ARTERIES carry? • blood • Oxygen-poor blood • Oxygen-rich blood
True or False? When the heart pumps oxygen- rich blood, it provides ITSELF with oxygen-rich blood. TRUE!
What do VEINS carry? • blood • Oxygen-poor blood • Oxygen-rich blood
Where does oxygen-poor blood need to go once it enters the right side of the heart? • to the lungs to get more oxygen • To the left ventricle to be pumped out to the body • To the brain
Once blood has picked up oxygen from the lungs, where does it go next? a. To right side of heart b. To the left side of the heart to be pumped out to body c. To left lung

Answer the following questions: What are the receiving chambers of the heart called? • Ventricles • Blood vessels • Atria
Answer the following questions: What are the pumping chambers of the heart called? • Ventricles • Blood vessels • Atria
Answer the following questions: Which heart chamber receives blood from the vena cava? • Left atrium • Right atrium • Both left and right atria
Answer the following questions: Which valve does blood go through when it passes from the right atrium to the right ventricle? • Bicuspid valve • Tricuspid valve • Pulmonary valve
Answer the following questions: Which valve does blood go through when it passes from the right ventricle to the pulmonary artery? • Bicuspid valve • Tricuspid valve • Pulmonary semilunar valve
Answer the following questions: Oxygenated blood travels from the lungs back to the heart through which vessels? • Pulmonary veins • Pulmonary arteries • Aorta and vena cava
Answer the following questions: Which heart valve does blood pass through from the left atrium to the left ventricle? • Aortic valve • Mitral valve • Tricuspid valve
Answer the following questions: When the left ventricle contracts, which valve does it pass through in order to get to the aorta? • Aortic semilunar valve • Pulmonary valve • Mitral valve
Answer the following questions: What keeps blood flowing in the correct direction within the heart? • Ventricles • Blood vessels • Valves
Answer the following questions: What does “vascular” refer to? • Ventricles • Blood vessels • Atria

Answer the following questions: (2) What is the heart’s primary job or function? • Attach to the blood vessels • Pump oxygen-rich blood to the brain and organs of the body • Refill after rest
Answer the following questions: (2) What is it called when the blood is pumped to the brain and body’s organs and tissues? • Systemic circulation • Pulmonary circulation • systole
Answer the following questions: (2) What is it called when the heart pumps oxygen-poor blood to the lungs to pick up oxygen? • Systemic circulation • Pulmonary circulation • diastole
Answer the following questions: (2) What is systole ? • Relaxation/refilling phase of a cardiac cycle • Pumping/contracting phase of a cardiac cycle • Blood pressure
Answer the following questions: (2) What is diastole? • Relaxation/refilling phase of a cardiac cycle • Pumping/contracting phase of a cardiac cycle • Blood pressure
Answer the following questions: (1) Based on the definition of word parts for CARDIOVSCULAR, what anatomical structures are included in the Cardiovascular system? • Heart and lungs • Heart and blood vessels • Heart and brain
Pathological Conditions Cardiovascular System
Things can go wrong. . . There are many things that can go wrong with the heart and blood vessels.
“Myocardial” in parts: My/o = cardi = -al = Muscle Heart Pertaining to Simple definition: Pertaining to the heart muscle
“Infarction” in parts: Infarct = -ion = Death of tissue Process or action Simple definition: Process or action of death of tissue
Parts-based Definition So, putting all of it together, we could make a simple definition for “Myocardial Infarction”: “Pertaining to death (process of dying) of the heart muscle.”
Pathological Conditionsof the Blood Vessels Aneurysm (pronounced: AN-yoo-rizm) is a localized sac-like bulge in the wall of an artery. It usually forms at a weak point in the arterial wall. It can rupture and lead to serious internal bleeding.
Pathological Conditionsof the Blood Vessels Arteriosclerosis (also called Atherosclerosis) Watch the short video: http://www.nlm.nih.gov/medlineplus/ency/anatomyvideos/000006.htm
Pathological Conditionsof the Blood Vessels Hypertensionis a condition in which the patient has a higher blood pressure than normal (exceeds 140/90 mmHg).
Comprehension Check: What is the definition you learned for “Pathological”? • Pertaining to the heart • Pertaining to discomfort • Pertaining to the knowledge/study of diseases
Comprehension Check: Which of the following choices are good examples of signs and symptoms related to problems with the heart and blood vessels? • Choking, coughing • Anxiety, chest pain • Runny nose, headache
Comprehension Check: What does “coronary” mean? • Pertaining to muscle • Pertaining to the blood vessels • Pertaining to the heart
Comprehension Check: Which term means “pertaining to the heart muscle”? • Coronary • Myopathy • Myocardial
Comprehension Check: Condition of extremely rapid, incomplete and ineffectual twitching-like contractions of the ventricles; often results in cardiac arrest. • Ventricular tachycardia • Ventricular fibrillation • Ventricular flutter
Comprehension Check: Caused by a partially blocked coronary artery, this condition is considered a “warning” of a possibly bigger cardiac event in the future. • Myocardial Infarction • Heart Attack • Angina Pectoris
Comprehension Check: Caused by a completely blocked coronary artery, this event is a medical emergency because more heart tissue can die with each passing minute. • Myocardial Infarction • aneurysm • Angina Pectoris
Comprehension Check: A test used to help determine if an MI occurred; relates to an elevated amount of “released” cardiac enzymes. • angiography • Cardiac enzymes test • Cardiac catheterization
Comprehension Check: A record or picture used to help determine abnormalities of the electrical action of the heart muscle. • Electrocardiogram • echocardiography • Event monitor
