Circulatory System
20
Myocardium:Consists of thick bundles of cardiac muscles twisted and whorled into ring-like arrangements
Hemoglobin:The protein in a red blood cell that allows it to carry oxygen
Veins:Vessels that transport blood back to your heart
Aorta:Largest artery in the body; Is about the diameter of a garden hose
Murmur:Abnormal swishing sound caused by improper closure of the heart valves
Pericardium:Double-layered membrane surrounding the heart
Septum:Partition or wall dividing a cavity; such as between the right and left atria and right and left ventricles
Blood:There is about 5 liters circulating through an adult body.
CirculatorySystem:System that contains heart, blood, and blood vessels
WhiteBloodCells:Attack and destroy foreign objects that enter the body
Plasma:Makes up about half of your blood.
RedBloodCells:Cells in the blood containing hemoglobin; carry oxygen
Platelets:Cell fragments in the blood; help form blood clots
Atriums:Two upper chambers of the heart
Ventricles:Two lower chambers of the heart
Arteries:Vessels that transport blood away from your heart
BloodVessels:Hollow tubes that flow blood throughout the body; Estimated to 60,000 miles long
Heart:Organ that pumps blood with enough pressure to squirt blood 30 feet
VenaCava:Veins that return deoxygenated blood from the body into the heart
Valves:Structures in the heart that control the direction of blood flow
