What is another name for interior house walls?
Partition walls.
What is noticeable about the muscular walls of the atria and the ventricles?
The walls of the left ventricle are thicker due to having to pump the blood to the body. The walls of the right ventricle are thinner because blood is being pumped into the lungs for gas exchange.
What are the lower two chambers of heart called?
The lower two chambers of the heart are the ventricles. The left ventricle is larger, with thicker walls, than the right ventricle.
The alternationg expansion and contraction of artery walls caused by the contrction and relaxation of the ventricles can be felt if you touch your wrist?
Pulse
When viewing a dissected heart it is easy to visually discern the right and left ventricles from each other by?
It is easy to visually discern the right and left ventricles from each other by observing the thickness of the ventricle walls.
How do walls of the artia compare with the walls of the ventricles?
Much thinner.
In longitudinal section how do the walls of the atria and ventricles differ?
In longitudinal section, the walls of the atria are thinner, and lined with pestinate muscles. The walls of the ventricles, meanwhile, are thick and muscular.
What causes the atrio ventricular valves to close?
The rise in pressure inside the ventricles, when the walls of the ventricles contract.
What is heart string?
Hold the valves to inner walls of ventricles
What is another name for interior house walls?
Partition walls.
Why have the ventricles got thicker walls then the atria?
atria are just the receiving chambers, it is the ventricles that actually pump the blood into the pulmonary and systemic circuits
Why do arteries able to adjust to the high pressure of the blood when ventricles pump blood?
Because the have thicker walls and sensors in the walls
Functions of the atria?
They have thin walls and they collect blood before it enters the ventricles.
What happens when a persons ventricles have thinner walls then normal?
it breaks more easily
Why are the walls of left ventricles thicker than the walls of right ventricles?
Because the left ventricle pushes blood through most vessels in the body, so it's thicker because more force is needed for the contraction.
What percent of blood pass from the atria to the ventricles before the atrial walls contract?
70% the remaining 30% is pushed into the ventricles during atrial systole
The alternating expansion and contraction of artery walls caused by the contraction and relaxation of the ventricles?
Pulse.
