Cardiovascular
| Question | Answer |
|---|---|
| What is an artery? | Blood vessel that carries oxygenated blood. |
| What is an arterioles? | Smaller arteries. |
| What are veins? | Blood vessels that carries deoxygenated blood, carbon dioxide. |
| What are venules? | Smaller veins. |
| What are capillaries? | Smallest arteries and veins. |
| What is vasodilation? | Increased diameter of arteries. |
| What is vasoconstriction? | Decreased diameter of arteries. |
| What does vasodilation cause? | Hypotension(low blood pressure). |
| What does vasoconstriction cause? | Hypertension(high blood pressure). |
| What cavity is the heart housed in? | Thoracic cavity. |
| What is the region between the sternum and vertebrae, from a lateral view, called? | Mediastinum. |
| What is the membranous sac around the heart called? | Pericardium. |
| What is the outer layer of the heart called, that is visible when an incision is made to the pericardium? | Epicardium. |
| What is the muscular layer of the heart, in between the endocardium and the epicardium called? | Myocardium. |
| What is the inner layer of the heart called? | Endocardium. |
| What is septa? | The walls that separate the chambers of the heart. |
| The inferior and superior venae cavae serves what purpose? | It delivers deoxygenated blood to the right atrium. |
| What are the largest veins in the body? | The superior and inferior venae cavae. |
| What is the location of the right atrium? | Superior right chamber of the heart. |
| What valve separates the right atrium from the right ventricle? | Tricuspid valve. |
| What type of blood moves from the right atrium to the right ventricle? | Deoxygenated blood- carbon dioxide. |
| After blood has entered the right atrium, where does it go next? | Right ventricle. |
| What is the location of the right ventricle? | Inferior right chamber. |
| What is the purpose of the valves? | To prevent regurgitation, or refluxing, of blood. |
| What is a murmur, or bruit? | A sound caused by valvular regurgitation. |
| Where does the deoxygenated blood from the right ventricle travel? | To the pulmonary trunk. |
| What valve is located at the entrance of the pulmonary trunk? | The pulmonary semilunar valve. |
| Where does the deoxygenated blood go from the pulmonary trunk? | Through the right and left pulmonary artieris to the lungs. |
| What happens in the lungs? | Respiration. |
| What is respiration? | The exchange of gases-carbon and carbon dioxide. |
| How does the oxygenated blood from the lungs get to the left atrium? | Through the pulmonary veins. |
| Where is the location of the left atrium? | Superior left chamber. |
| The oxygenated blood from the left atrium goes to the left ventricle through what valve? | Bicuspid (mitral) valve. |
| Where does the oxygenated blood go from the left atrium? | Through the bicuspid valve to the left ventricle. |
| Where is the location of the left ventricle? | Inferior left chamber. |
| The left ventrical pumps oxygenated blood through what valve? | Aortic semilunar valve. |
| Where does the aortic semilunar valve allow the oxygenated blood to enter? | The ascending aorta. |
