What is a bathyscape?
A deep diving device. The part of a submersible that withstands the external pressure.
What does PN stands for in 250PN 16 uPVC?
250 nominal diameter, withstands of 16 bar pressure UPVC pipe,
Why are dams built stronger and broader at the bottom?
Because water pressure is more intense at depth than it is near the surface - hence the dam has to be stronger at the bottom - it withstands more pressure at the bottom.
Why does clay make good bricks?
Clay makes good bricks because it is a stable substance. This substance gets hard and withstands a great amount of pressure.
Money that withstands time is considered?
durable
What controls venous blood pressure?
The heart. All blood pressure is controlled by the heart.
What is the relationship between the heart and blood pressure?
Heart rate and blood pressure are intimately related. Nerves and hormones constantly monitor and balance the heart rate and blood pressure.
What is diastolistic pressure?
Diastolic blood pressure is the lower number in a blood pressure reading, representing the pressure in the arteries when the heart is at rest between beats. It is an important measure of heart health and can indicate the pressure on the arteries during relaxation of the heart muscle.
Pressure of the blood coming out of the heart?
This pressure is termed the aortic pressure.
What generates blood pressure?
Blood pressure is generated by the force exerted by the heart pumping blood into the arteries and the resistance encountered by the blood flow in the arteries. The systolic pressure is the pressure when the heart contracts and pushes blood out, while the diastolic pressure is the pressure when the heart relaxes and refills with blood.
What is differenc between the blood pressure and heartbeat?
The heart beat is the beating of the heart. Blood pressure is the amount of pressure the heart beat causes the blood to push against the blood vessels.
Explain why blood pressure is expressed with two numbers?
Diastolic: Referring to the time when the heart is in a period of relaxation and dilatation(expansion). Systolic: The blood pressure when the heart is contracting. Measuring the pressure into and out of the heart.
