Circulatory System Flashcards
Cardiovascular System
The Cardiovascular System consists of the heart, blood vessels and blood. It is responsible for delivering blood to different parts of the body
Valves
Valves keep blood flowing in one direction. The heart has these and veins have these.
Left Ventricle
The left ventricle receives oxygenated blood from the left atrium and pumps it to the aorta
Right Ventricle
The right ventricle receives deoxygenated blood from the right atrium and pumps it to the pulmonary artery
Left Atrium
The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle
Right Atrium
The right atrium receives deoxygenated blood from the vena cava and pumps it to the right ventricle
Deoxygenated
Deoxygenated blood contains no oxygen
Oxygenated
Oxygenated blood contains oxygen
Aorta
The aorta receives oxygenated blood from the left ventricle and pumps it to the body
Vena Cava
The vena cava receives deoxygenated blood from the body and carries to the right atrium
Vein
The vein carries blood to the heart and usually deoxygenated. Thinner walls, large opening and contains valves to prevent back flow of blood
Artery
The artery carries blood away from the heart and usually oxygenated. Thick and muscular walls to withstand high pressure and small opening
Capillary
The capillary allows diffusion of gases and nutrients from blood into the body cells. Very thin and one cell thick. Small hole and walls are semi-permeable.
Pulmonary Artery
The pulmonary artery carries deoxygenated blood away from the right ventricle to the lungs
Pulmonary Vein
The pulmonary vein returns oxygenated blood from the lungs to the heart
