Circulatory System Test Flashcards
Arteries
Blood vessel that carries blood away from heart
Aortic valve
Flap or cost located between the left ventricle of the main part in the aorta
Blood
Fluid that circulates through the vessels in the body to carry substances to all body parts
Capillaries
Tiny blood vessel that connects arterioles and venules and allows for the exchange of nutrients and gases between the blood and body cells
Circulatory system
Transportation system of the body also known as cardiovascular system
Diastole
Period Of relaxation of the heart
Endocardium
Series of membranes lining in the heart
Erythrocytes
Red blood cell
Hemoglobin
The iron containing protein of the red blood cell
Left atrium
Receives oxygenated blood from Longs
Left ventricle
Receives blood from the left atrium and pumps blood into the aorta for transport
Leukocytes
White blood cell
Mitral valve
Flapper cost between the left atrium and left ventricle of the heart
Myocardium
Muscle layer of the heart
Pericardium
Membrane sac that covers the outside of the heart
Plasma
Liquid portion of blood
Pulmonary valve
Flapper cost between the right ventricle and pulmonary artery
Right atrium
Receives blood is it returned from the body cells
Right ventricle
Receives blood from the right atrium and pumps the blood into the pulmonary artery
Septum
Membrane wall that divides the two cavities
Systole
Period Of work or contraction of the heart
Thrombocytes
But still required for clotting of blood cells
Tricuspid valve
Flapper cost between the right atrium and right ventricle of the heart
Vein
Blood vessel that carries blood back to the heart
Arrhythmia
Abnormal heart rhythm (aorta contracts)
Systole process
Right ventricle into pulmonary artery to longs for oxygen. Left ventricle to aorta sending blood to other parts
Conductive pathway steps
SA node. Pathways throughout aorta. AV node. Purkinje system
Arrhythmia tests
Cardiac monitors and electrocardiograms
Superior and inferior vena cava
Largest veins in the body
What vessels prevent backflow of blood
Vein
Most elastic and muscular blood vessels
Arteries
Substances dissolved in plasma
Proteins carbs potassium calcium
Substances transported by blood
Oxygen carbon dioxide metabolic waste hormones heat nutrients
Erythrocyte function
Carries oxygen and carbon dioxide
Leukocyte function
Phagocytosis
Thrombocyte function
Help clotting
Hemoglobin color (what is blue, what is red)
Bright red equals high and oxygen. Low oxygen equals blue
