Circulatory system
| Question | Answer |
|---|---|
| Circulatory system | Pumps nutrients and other essential materials to the cells and removes waste products from the cells through a system of vessels |
| Septum | A partition separating the two chambers of the heart |
| Right Atrium | Receives unoxygenated blood from the veins |
| Left Atrium | Receives oxygenated blood from lungs and pumps it to the lungs through pulmonary artery |
| Left ventricle | Pumps blood into the Aorta which delivers blood through the body |
| Right ventricle | Receives blood from the right Atrium and pumped it to the lungs through pulmonary artery |
| Valve | Allows blood to flow in only One Direction |
| diastole | The phase of the heartbeat when the heart muscle relaxes and allows the chambers to fill with blood |
| systole | The phase of the heartbeat when the heart muscle contracts and pumps blood from the chambers into the arteries |
| Artery | Carries oxygenated blood from the lower chambers of the heart (ventricles) to all parts of the body |
| Capillary | Any of the fine branching of blood vessels that form a network between the arterioles and venulses |
| Vein | Carries unoxygenated blood from all different parts of the body and returns it to the heart |
| Blood | The red liquid that circulates in the arteries and veins caring oxygen and carbon dioxide to and from tissues |
| Plasma | The component of blood that normally hold the blood cells and a whole blood and suspension |
| Erythrocytes | Contains a pigment of hemoglobin which imparts the red color to blood and transports oxygen and carbon dioxide to and from tissue |
| Hemoglobin | A red protein responsible for transporting oxygen in the blood |
| Leukocytes (White blood cells) | Circulates in the blood and body fluids and is involved in countereacting foreign substances and disease |
| Thrombocytes | Found in large numbers in blood and involved in clotting |
| Arterioles | are no thicker than human hair and carries blood away from arteries into the capillaries |
| venules | Carries blood back to the veins after exchanges have occurred in the capillaries |
| aorta | Largest artery in body |
| Capillaries pt2 | Are single layer of cells that are responsible for exchanging carbon dioxide and oxygen |
| Pulmonary veins | sends oxygenated blood back to the heart from lungs Part of pulmonary circulation |
| Arteries small vessels are called | Arterioles |
| Arteries blood pressure | High |
| Arteries wall structure | Large thick walled vessels |
| Arteries Special feature | Elasticity |
| arteries example | Aorta |
| Veins small vessels are called | venules |
| Veins blood pressure | Low blood pressure |
| Veins wall structure | Thinner wall structure |
| Veins special feature | One way valves |
| Vein example | Vena Corta |
| in what direction do capillaries carry blood | into capillary bed |
| Capillaries blood pressure | Medium blood pressure |
| Capillaries wall structure | thin walled |
| Capillaries special feature | gas exchange |
| example of a capillary | lymphatic capillary |
| Blood | transports oxygen and nutrients heat transports waste to be cleared out |
| 4 components of blood | Plasma Erythrocytes Leukocytes Platelets |
