Type of circulatory system in which blood flows out through vessels and sinuses.
Open Circulatory System
Type of circulatory system in which blood confined within connected walls of heart and blood vessels. General Characteristics: heart pumps blood, blood flows slowest in capillaries.
Closed Circulatory System
Type of Blood Vessel that is small and branch into capillaries. They usually carry oxygen rich blood.
Arterioles/ Arteries are larger.
These Blood Vessels carry blood back to the heart. They are smaller in diameter than arteries, usually carry oxygen-poor blood.
These are small veins.
These blood vessels are smallest in diameter, connect veinuous and arterial systems in capillary bed.
Type of blood circuit that functions to oxygenate the blood. Starts from the heart's right half to capillary beds located in lungs. The circuit then returns to the left half of blood.
Pulmonary Circuit
Type of blood circuit that functions to distribute oxygen rich blood and nutrients to body. Starts in the Left and Returns on the Right.
Systemic Circuit
Part of the heart that consists of the two upper chambers.
Atrium (Plural Atria)
The atrium that receives oxygen-poor blood from superior and inferior vena cava.
Right Atrium
The atrium that relieves oxygen-rich blood from the lungs, via the pulmonary veins.
Left Atrium
Parts of the heart that consists of the two lower chambers.
This ventricle pumps oxygen-poor blood from pulmonary arteries.
Right Ventricles
This ventricle pumps oxygen-rich blood to aorta.
Left Ventricle
These parts of the heart are located between the atrium and ventricles, they prevent blood back flow.
This valve, is located between right atrium and right ventricle.
Right AV (AKA Tricuspid Valves)
These valves are located between the left atrium and left ventricle.
Left AV (AKA Mitral Valve)
This valve is located between right ventricle and pulmonary trunk.
Pulmonary semi lunar valve.
This valve is located between the left atrium and the left ventricle.
Aortic semi lunar valve.
This structure in the heart is a tendon-like tissue attached to valves (white and webby). They open and close valves by papillary muscles.
Chordae Tendinae
This is another name for the entire heart.
This blood vessel receives oxygen-poor blood from ABOVE the shoulder.
Superior Vena Cava
This blood vessel recieves oxygen-poor blood from below the shoulder.
Inferior Vena Cava
This vessel is large and leaves the right ventricle.
Pulmonary Trunk
These vessels carry oxygen-poor blood to the lungs
Pulmonary Arteries
These vessels carry oxygen-rich blood from lungs to the heart.
Pulmonary Veins
This large vessel carries oxygen-rich blood from left ventricle to the rest of the body. 1" in diameter.
Carry rich blood to heart muscle
Coronary Arteries (red)
Carry oxygen-poor blood away from heart muscle
Coronary Veins (blue)
This is located in the upper wall of the right atrium.
Sinotrial Node (Pacemaker)
These are located in the wall between the right atrium and right ventricle. They make sure that the atria are empty before the ventricles contract.
Atrio ventricular node
When the heart passively fills with returning blood and then actively contracts pumping out blood.
Cardiac Cycle
Cycle in which heart relaxes and blood flows in
brief contraction of the atria to completely fill ventricle
Volume of blood that the ventricle pumps into the systemic system.
Cardiac Output
A drop of blood begins at one of these two places to begin the circulatory system.
Superior /Inferior Vena Cava
Heart sound that indicates closing of AV Valves
Heart sound that indicates closing of semi-lunar valve.
This results from improper closing of heart valves. Valves can be leaky and may hiss.
Heart murmur.
This disorder is caused by patchy deposits of fatty material on walls of arteries.
