Yes. It is lower by 7.6 points for the upper extremities. Reasoning: bp is measured in mm of Mercury. The specific weight of mercury is 76 kg/ltr With a gravitational constant of ~10 m/sec^2 this leads to 7.6 mm of mercury column rise for a 1 meter column of water. Assuming that the specific mass of blood is close to that of water, and The difference in height between upper and lower extremities is roughly 1meter. (3feet) we get about 7.6 points more in the legs. Leo Grassens

Why use trendelenburg position for anaphylactic shock?
The Trendelenburg position is used for patients in shock to increase blood flow, by gravity, from the major vessels in the lower extremities to the brain to help increase the blood pressure enough to keep the patient stable until advanced medical care is available.
What types of vitamins help lower high blood pressure?
You should not take any sort of vitamins, especially ones claiming to lower blood pressure without talking to your doctor. It sounds like there may be an underlying problem to your high blood pressure.
Where are the long bones located?
The "larger" bones in the body are located in the extremities, such as the femur, tibia and fibula in the lower extremities, and the humerus, radius and ulna in the upper extremities.
Which lake have a higher elevation or a lower elevation to dissolved mineral?
Higher elevation is going to also have higher atmospheric pressure. My recollection is that the higher pressure of the atmosphere on the surface of the lake will cause a higher level of absorption in the lake itself.
Why is blood pressure higher lying down than sitting or standing?
In most cases, body position has very little effect on blood pressure. In many cases, the blood pressure will rise a little as a result of the heart rate going up when sitting or standing compared to lying down. Some people have an imbalance in their Autonomic Nervous System, which controls constriction and dilation of blood vessels and may find that their blood pressure is lower when standing as opposed to when lying down or sitting.
Does ADH lower blood pressure?
no higher the blood pressure
When there is an increase in blood pressure does it get lower or higher?
higher
Abruptly stopping intense exercise causes blood to pool in the lower extremities?
Abruptly stopping aerobic activity can cause blood pooling in your lower extremities or making you feel lightheaded.
Can blood pressure be taken in the arm with the PICC line?
No. Use the other arm or lower extremities if it's appropriate.
Can different temperatures of water lower your blood pressure?
Yes. The hotter the water,the higher your blood pressure and vice verser xx
What is the difference of the blood coming from the heart and blood coming from the lungs?
Blood coming from the lungs has lower pressure while that from the heart has higher pressure. Blood coming from the lungs also has higher oxygen content and lower carbon dioxide content compared to that coming from the heart.
When the body is working harder is the blood pressure higher or lower?
Naturally, your blood pressure is higher when it is working harder as in running, body work, etc. High blood pressure can also be caused by stress, anger problems, etc. So the result is that your blood pressure is higher when working than at rest.
Does pressure drop when blood moves from arteries to veins?
Yes. Blood always flows from a higher pressure to a lower pressure, so as the blood moves from the arteries through the capillaries and into the veins pressure drops considerably.
What do you call when a person stands up too quickly and his blood pressure drops?
During rest,the blood pressure drops to a minimal level. When one stands up from a supine or sitting position,the effect of gravity tends to work on the circulation such that the blood in the upper extremities rapidly flows to the lower extremities thus there is an increased pressure in the lower extremities while the upper extremities has low blood pressure thus this account for the low volume of venous return which direcly affect the cardiac output. Decreased cardiac output is dangerious to the vital organs in the body such as heart and brain.syncope may ensue due to low blood flow to the brain.among other features include loss of consciousness,dizziness,myocardialischaemia expressed as angina etc
Why are there compartments in the lower extremities and not the upper extremities?
There are compartments in both the upper and lower extremities.
Air moves from where pressure is higher to lower or lower to higher?
