Carry oxygenated blood away from the heart to the rest of the body, thick walls to withstand pressure
Veinsโจ
Carry deoxygenated blood back to the heart, thin walls, less pressure than arteries
Capillariesโจ
Tiny vessels for exchange of oxygen, nutrients, and waste between blood and tissues, thin walls for diffusion
Right Atriumโจ
Receives deoxygenated blood from the body through the superior and inferior vena cavae, blood flows into the Right Ventricle through the Tricuspid Valve
Right Ventricle
PumpsdeoxygenatedbloodfromtheRightAtriumtotheLungs through the Pulmonary Artery, thickmuscularwalls for powerful contractions
Left Atriumโจ
Receives oxygenated blood from the Lungs through the Pulmonary Veins, blood flows into the Left Ventricle through the Mitral Valve, thin walls due to less pressure
Left Ventricleโจ
