| Question | Answer |
|---|---|
| Closed system by which blood is circulated to all parts of the body. | Cardiovascular System |
| Major structures of the Circulatory System. | The Heart, Blood, and Blood Vessels. |
| 4 chambers, hollow, muscular organ, 2 sides (right and left chambers), the right and left chambers are separated by the septum, and valves between chambers prevent back flow. | Heart Structures |
| Outer thin layer of the heart. | Epicardium |
| Middle muscle layer of the heart. | Myocardium |
| Inner thin layer of the heart. | Endocardium |
| The upper chambers on each side of the heart are called: | Atria |
| The lower chambers on each side of the heart are called: | Ventricles |
| The upper chambers of the heart are: | Receiving Chambers |
| The lower chambers of the heart are: | Delivering Chambers |
| Receives deoxygenated blood from the body via superior and inferior vena cava. | Right Atrium |
| Receives blood from the right atrium and pumps in into the lungs. | Right Ventricle |
| Receives oxygenated blood from the lungs. | Left Atrium |
| Receives blood from the left atrium and pumps it to the body via aorta. | Left Ventricle |
| Inferior and superior vena cava bring blood from the body to the right atrium. | Vena Cava |
| Take blood from the right ventricle to the lungs. | Pulmonary Arteries |
| Carries blood away from the heart to the body. | Aorta |
| Bring oxygenated blood from the lungs back to the heart. | Pulmonary Veins |
| Controls flow of blood from right atrium to right ventricle. | Tricuspid Valve |
| Controls flow of blood from the right ventricle to pulmonary arteries. | Pulmonic Valve |
| Controls flow of blood from the left atrium into the left ventricle. | Mitral Valve (Biscupid Valve) |
| Controls flow of blood from the left ventricle into the aorta. | Aortic Valve |
| Contracts at the same time, pushing into the ventricles, then they relax. | Right and Left Atria |
| The right ventricle contraction pushes blood into the pulmonary artery towards the lungs, the left ventricle contraction pushes blood into the aorta for delivery into the entire body, then they relax. | Right and Left Ventricles |
| Contracting Phase | Systole |
| Relaxing Phase | Diastole |
| After the atria and ventricles have contracted once, they all briefly relaxed, and then starts again. | Cardiac Cycle |
| Average blood pressure. | 120/80 |
| Measures the force (pressure) placed by the blood on the walls of blood vessels. | Blood Pressure |
| The pressure in the arteries while the ventricles are contracting. | Systolic Pressure |
| The pressure in the arteries while the ventricles are relaxing. | Diastolic Pressure |
| The rhythmic contraction and relaxation of the arterial blood vessels in response to the contraction and relaxation of the heart. | Pulse |
| All blood will circulate throughout the entire body every 2 minutes. | Heart Rate and Cardiac Output |
| Number of heart beats/minute. | Heart Rate |
| 72 beats/minute. | Normal Heart Rate |
| Volume of blood pumped in 1 minute. | Cardiac Output |
| 5 liters of blood/for a person weighing 145lbs. | Average Cardiac Output |
| Two Divisions: Pulmonary Circulation and Systemic Circulation | Cardiovascular System |
| Carries deoxygenated blood from the heart to the lungs so carbon dioxide can be released; blood picks up oxygen in the lungs and returns it to the heart. | Pulmonary Circulation |
| Carries oxygenated blood along with nutrients to all cells of the body; removes waste products from the cells and delivers them to excretory organs; returns deoxygenated blood to the heart. | Systemic Circulation |
| Arteries, arterioles, capillaries, venules, and veins. | Blood Vessels |
| Carry blood away from the heart; thicker walls; have a pulse that can be felt. | Arteries |
| Carry blood towards the heart; thinner walls; have valves to prevent blood from back flowing. | Veins |
| Carry oxygenated blood from the heart to the body. | Systemic Arteries |
| Carry deoxygenated blood from the heart to the lungs. | Pulmonary Arteries |
| Carry deoxygenated blood from the body to the heart. | Systemic Veins |
| Carry oxygenated blood from the lungs to the heart. | Pulmonary Veins |
| Smallest of all the blood vessels; microscopic, one-cell thick blood vessels; connect arterioles and venules. | Capillaries |
| The thin walls of the capillaries let the carbon dioxide move out of the blood to be exhaled; let oxygen from air breathed in move into the blood; the oxygenated blood flows through the capillaries then the venules then the veins to the heart. | Capillaries of Pulmonary Circulation |
| Arterial blood with oxygen and nutrients travels into the capillaries; thin walls of capillaries let the oxygen and nutrients move out of the blood into the surrounding tissue; carbon dioxide and waste are picked up and carried away in the venous blood. | Capillaries of the System Circulation |
| An open system by which tissue fluid is returned to the blood stream. | Lymphatic System |
| Returns tissue fluid to the bloodstream, protects the body, process lymphocytes, and delivers fats to the blood stream. | Lymphatic Functions |
| Lymph fluid, lymphatic vessels, ducts, and nodes. | Lymphatic Structures |
| Capillaries, vessels and nodes, right lymphatic duct, thoracic duct, and large veins. | Lymph Flow |
