Circulatory System Flashcards
The system that delivers oxygen and nutrients to all of the cells in the body and carbon dioxide and waste to the lungs through blood vessels
Circulatory System
The main organ of the circulatory system
the heart
The three types of blood vessels
arteries, veins and capillaries
sends blood from the heart to the lungs and back
pulmonary circulation
sends blood to the rest of the body and back to the heart
systemic circulation
the main artery of the heart carrying oxygenated blood to all parts of the body except the lungs
aorta
large vein carrying deoxygenated blood back to the heart from the upper body
superior vena cava
large vein carrying deoxygenated blood back to the heart from the lower body
inferior vena cava
a muscular organ about the size of a fist located slightly behind the left of the breastbone
heart
The two upper chambers of the heart
left atrium and right atrium
the two lower chambers of the heart
left ventricle and right ventricle
The valve between the right atrium and the right ventricle
tricuspid valve
the valve between the left atrium and left ventricle
mitral valve
the valve between the left ventricle and the aorta
aortic valve
the valve between the right ventricle and the pulmonary artery
pulmonary valve
very tiny blood vessels that deliver oxygen and nutrients to the cells and pick up carbon dioxide and waste
capillaries
These vessels carry oxygen and nutrients away from the heart to the body
arteries
These vessels carry carbon dioxide and waste towards the heart
veins
hardening of the arteries due to plaque
artherosclerosis
another word for a heart attack, blockage of blood flow
myocardial infarction
disease that causes blood to flow backward
prolapsed valves
abnormal heart rate
arrhythmia
condition that causes the heart to work harder
high blood pressure
