What are the fibrous structures in the heart that prevent prolapse of the cuspid valves?
Chordae tendineae - attached to the valves between both atria and ventricles... these structures are attached to papillary muscles in the bottom of the ventricles. these contract when the valves contract, this keeps the blood from going back up into the atria.
Which structures control the flow of blood through the heart and What governs the functioning of these structures?
Valves and blood vessels control the flow of blood through the heart. The aorta governs the functioning of these structures by being the main artery in the cardiac system.
What structures make the heart an efficient pump?
The left and right ventricles, which when they contract pump blood into the systemic and pulmonary curcuits.
Which structures pump the blood from the heart?
Blood moves to the right ventricle where it is pumped to the lungs.
What artery provides blood to the deep structures of the face?
Maxillary

What type of muscle tissue lines hollow structures like ducts and blood vessels that contract involuntarily?
Smooth muscle (involuntary)lines ducts and vessels.
What contract together to pump blood?
The ventricles contract to pump blood out of the heart.
The force with which the contract causes blood pressure?
the force with which what the contract causes blood pressure
What structures filter blood in the kidneys?
The structures are the glomerulus and tubules.

When the atria contract the blood is forced into the?
The blood is squeezed into the ventricles.
When the ventricles contract blood is pumped...?
Yes. Actually when any of the 4 chambers contract the pump blood. The ventricles pump blood to the body and to the lungs.
Which phase in cardiac cycle is systolic pressure?
Blood flows into the relaxed atria while the ventricles contract. <rephrased> The ventricles contract, carrying blood into the aorta, and blood flows into the relaxed atria.
How would you describe the blood vessels?
tube like structures which carries the blood
What are two structures that are shared by the blood and the lymphatic system?
These two structures are the lymph nodes and the spleen.
