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 |
