Can you have left ventricular hypertrophy and low blood pressure?
No, force of blood is more in the ventricles then you will have high BP.
Does blood get pushed from the atria?
Yes, but weakly (i.e. low pressure).
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.
How do the walls of the Atria compared with the walls of the ventricles and why are they different?
The short Answer: The ventricles have thicker walls than the atrium simply because this is the part of the heart that does most of the pumping action by contracting. It has to be strong and fairly thick to cope with the pressure. (Ventricles have thicker walls than the atrium, which creates a higher blood pressure. The left ventricle has thicker walls because it needs to pump blood to the whole body. The wall of the left ventricle is 8-15 mm The right atrium's wall is approximately 2mm in thickness, due to the combined influence of the low pressure of this chamber and the ease of pumping to low pressure areas)

Does it move from an area of high pressure to low pressure or low pressure to high pressure?
A fluid will move from high pressure to low pressure.
What condition cause deviations from the ideal gas?
High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.
Would a cyclonic flow be high-pressure or low-pressure?
Low pressure - cyclone High pressure - anticyclone
Are hurricanes low pressure or high pressure?
Hurricanes are low pressure systems.
Is an anticyclone high pressure?
yes, anticyclones are high density and high pressure and cyclones are low density and low pressure
How many seconds are in one cardiac cycle?
The cardiac cycle is the sequence of events that makes up one heartbeat: * Oxygenated blood enters the left atrium of the heart under high pressure from the pulmonary vein, and deoxyenated blood enters the right atrium of the heart under low pressure from the vena cava. * The atria gradually fill and become distended. As they fill up the pressure in the atria exceeds the pressure in the ventricles, and the tri and bicuspid valves are forced open and some blood enters the relaxed ventricles. This stage is called diastole. * The atria then contract, in a stage called atrial systole, and blood is forced into the ventricles. Almost immediately after atrial systole, (approximately 0.1 seconds after) ventricular systole takes place where the ventricles contract. The bi and tricuspid valves slam shut, and the first heart sound 'Lub' is heard. * As pressure in the ventricles exceeds pressure in the aorta and pulmonary artery, the semilunar valves are forced open, and blood enters these elastic walled vessels. * Ventricular diastole follows. Some blood will tend to return back into the ventricles, but this causes the semilunar valves to slam shut. The second heart sound 'Dub' is heard. * The repeated relaxing and recoiling of the elastic fibres in the walls of the arteries as a result of ventricular systole forces blood along the arteries in a series of pulses. * The further away from the heart the blood is the less pronounced the pulse. * This whole series of events takes, on average, 0.8 seconds.
What does it mean when your systolic is low?
the systolic blood pressure is the pressure that the contraction of the ventricles have on the arteries, and a low systolic means a low pressure exerted by the ventricles of the heart. A low systolic would be below 90-100 on average but everyone is different. there are many different causes including orthostatic hypotension, which is a low blood pressure when rising from laying or sitting to standing (a common side effect of blood pressure medication and many other medications), heart attack, dehydration, and shock among many other conditions.
