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
ur aorta is located in te kidneys.:) its called Hydrostatic Preasure or blood preasure
It's because that it needs a cell wall to push against and an animal cell doesn't have one therefore nothing to push against.
muscle that push hard to wall
According to Newton's third law, the wall will push back against you with an equal force in the opposite direction.
The equal and opposite reaction is the wall pushing back against you. When you hit the wall with a stick, the force you exert on the wall is transferred to you through the stick, causing the wall to push back with an equal force. The stick simply transmits this force between you and the wall.
Blood pressure is the force exerted by the blood against the walls of the blood vessels. It is measured in millimeters of mercury (mmHg) and consists of two values: systolic pressure (when the heart beats) and diastolic pressure (when the heart is at rest). High blood pressure can lead to various health issues, so it is important to monitor and manage it.
The wall of the aorta is highly elastic and so distends when the left ventricle contracts pumping blood into it. As the walls close back in they push the blood along in a more smooth fashion. This stops sudden pressure increases from bursting all the vessels.
It makes the blood vessels narrow and then the blood has to push very hard to get through the blood vessel. When the blood vessels get skinnier, there's not enough room for all the blood to push through. It's like trying to drink something through a tiny, skinny straw. It's easier when the straw is wider, right? Same with the blood. It takes a lot more pressure to push through the narrow tube, just like it takes a lot more pressure for you to suck up your soda through a tiny, thin straw!
The amount of force exerted against the wall of an artery is called blood pressure. It is typically measured in millimeters of mercury (mmHg) and consists of two components - systolic pressure (the force when the heart beats) and diastolic pressure (the force when the heart is at rest).
Short answer: we do not have cell walls in our cells as plants do. The cell wall is required so that the turgor pressure has something to push against. Since we do not have cell walls, this is impossible.
Pressure is created by moving particles (fluid) bumping up against surfaces. In the case of blood hydrostatic pressure, blood is about 55% plasma and that plasma doesn't just flow down the length of the blood vessel but also pushes up against the sides of it creating blood hydrostatic pressure. Now there are different kinds of capillaries but in general they are all quite leaky. When you have fluid pressure pushing up against a leaky wall, some of that fluid is going to get out.
