The force exerted by a seedling as it pushes its way through the soil is due to the created inside its cells?
Water pressure
Why doesn't it make sense for grasshoppers to have high blood pressure?
Grasshoppers have an open circulatory system. This means that blood (which, in insects, is called haemolymph) is pumped by the heart straight into sinuses that surround the grasshoppers muscles, tissue, and organs. Unlike us humans who have closed circulatory systems, blood isn't delivered throughout the body in blood vessels like veins and arteries (except for the aorta). When blood is delivered through vessels throughout the body, there is a force exerted on the vessel walls. This force is called blood pressure.Grasshoppers don't have blood vessels throughout their bodies; all they have are the heart and aorta. Blood goes straight from the sinuses in the grasshopper's into the heart, and is pumped straight out of the aorta into the sinuses. The only pressure exerted is on the short aorta leading out of the heart-- and that's it. Because of this, they cannot have high blood pressures.I'm not 110% sure if that's all correct, but I hope it helps. I'm doing a biology assignment on the circulatory system of grasshoppers for high school right now, and I was looking for some answers myself... sucks when no one answers though, haha.
What is the primary driving force that produces glomerular filtration?
Osmotic pressure in the blood vessel or cell pushes water from a place with a lower concentration of dissolved solids (there is more water on that side, proportionally), to the other side if there is a higher concentration of dissolved solids (because proportionally there is less water)
Which chamber contracts to pump the blood at the highest pressure?
The Chamber that creates the highest pressure is the Left Ventricle. It must do this to get the blood all the way around the body, including right up to the top of the heat, but more importantly it must overcome the huge pressure in the Aorta. This is because of the Aortic Valve which sits stops the blood being pushy back formthe aorta into the ventrivle. The high blood pressure in the aorta holds this valve shut tight. A pressure greater than the one holding any vavle shut is required to open it, ie the ventricular presure must be greater than the aortic pressure is required to force the aortic valve open.
How does water get to the leaves in the top trees against the force of gravityname the property responsible for this and explain how it works?
Actually is by the help of the physical principle and property called "Turgor pressure.
What creates blood pressure?
The Cardiovascular system is slightly overfilled with blood , As result blood exerts an outward force against vessel wall , as it flow through them The term blood pressure refers to force exerted by Blood as it pressure against & Attempts to stretch the wall of blood vesseles
Blood pressure is exerted by the blood on the walls of blood vessels as a result of?
force/pressure
What part of blood pressure denotes the force exerted on the arterial walls during cardiac contraction?
The force exerted on the arterial walls during cardiac contraction is systolic blood pressure. In contrast, diastolic blood pressure is the force exerted during cardiac relaxation.
What is blood pressure-?
Blood pressure is the pressure of the blood in the circulatory system, often measured for diagnosis since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls.
Decreased temperature helps to facilitate increases in ROM?
Blood pressure is the force exerted by the blood against the inner walls of the blood vessels
Does blood pressure determine the force exerted by the blood on the walls of the arteries?
Yes it does.
Blood pressure is in the?
If the blood pressure is very high, then I would recommend to see a doctor who will be able to thoroughly examine and diagnosis the possible causes of why the blood pressure is raising so high.
What pressure describes the force exerted against the walls of the arteries when the heart is in a relaxed state?
Diastolic pressure
The force exerted on a surface divided by the area over which the force is exerted?
Pressure is the force exerted on an object divided by the area where the pressure was applied.
The force exerted against the arterial walls when the heart contracts called the?
Systolic Pressure.
What is the force exerted on surface divided by the area over whech the force is exerted?
That's the pressure on that particular area.
How do you call the force exerted on a surface divided by the area over which the force is exerted?
Pressure
