Science 1.3 Flashcards
Describes the movement of blood and lymph around the body which permits nutrient distribution, waste removal, communication and protection
Cardiovascular system / circulatory system
The two integrated circulatory systems
Closed circulatory system
Open lymphatic system
A double loop system consisting of thick walled arteries, thinner walled veins and capillaries
Closed circulatory system
Transports blood away from the heart
Arteries
Transports blood to the heart
Veins
A network that connects arteries to veins in tissues
Capillaries
System that circulates and filters interstitial fluid between cells and eventually drains into the circulatory system
Open lymphatic system
Carries deoxygenated blood from the right ventricle to the lungs and returns oxygenated blood to the left atrium
Pulmonary loop
Carries oxygenated blood from the left ventricle to the body, returning deoxygenated blood to the right atrium
Systemic loop
Names of the major arteries
Coronary artery Common Carotid artery Subclavian artery Brachiocephalic artery Thoracic aorta Pulmonary artery
Major veins
Internal jugular
Brachiocephalc
The two cycles of contractions of the heart
Systole and diastole
The contraction of the heart muscle
Systole
The relaxation of the heart muscle
Diastole
The cause of the atrioventricular valves to close makes “Lub” sound
Ventricular systole
