What direction do arteries travel in relation to the heart?
Away from the heart
What direction do veins travel in relation to the heart?
Towards the heart
What type of tissue is blood?
Connective
What valve connects the right atrium and the right ventricle?

In which circuit is the left ventricle found?
Systemic Circuit
What is the name of the smaller blood vessels that carry blood away from the heart?
Arterioles
What is the name of the smaller blood vessels that bring blood towards the heart?
What is the extracellular matrix of blood called?
Plasma
What valve connects the left atrium and the left ventricle?
Bicuspid Valve (Mitral Valve, Left Atrioventricular Valve)
What blood vessel brings blood from the lungs back to the left atrium?
Pulmonary Vein
How is blood pumped through the veins?
Contraction of surrounding skeletal muscles and valves to prevent back flow
What are the three formed elements found in blood?
Erythrocytes, Leukocytes, and Thrombocytes
What string-like structures help open and close the tricuspid and bicuspid valves?

Pericardium
What structure separates the right and left ventricles?
