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

How does cardiac output affect blood pressure?
Cardiac output is the amount of blood pumped by the heart in one minute. It directly affects blood pressure because an increase in cardiac output leads to higher blood pressure, while a decrease in cardiac output results in lower blood pressure. This is because the more blood the heart pumps, the more pressure is exerted on the walls of the blood vessels.
Why is venous pressure lower than arterial pressure?
Venous pressure is lower than arterial pressure because veins are distensible and have lower resistance compared to arteries. Veins are capacitance vessels that can expand to accommodate increased blood volume, whereas arteries are resistance vessels that have thicker walls and help maintain higher pressure to ensure blood flow to various tissues.
How can elevating your legs help to lower blood pressure?
Elevating your legs can help lower blood pressure by reducing the amount of work your heart has to do to pump blood throughout your body. When you elevate your legs, gravity helps to move blood back towards your heart, decreasing the pressure in your blood vessels and ultimately lowering your blood pressure.
How can elevating your legs help to lower high blood pressure?
Elevating your legs can help lower high blood pressure by reducing the amount of work your heart has to do to pump blood throughout your body. When you elevate your legs, gravity helps to move blood back towards your heart, decreasing the pressure in your blood vessels and ultimately lowering your blood pressure.
What is the name of the blood pressure measuered when the ventricles relax?
The blood pressure measured when the ventricles relax is called diastolic blood pressure. It is the lower number in a blood pressure reading, representing the pressure in the arteries when the heart is at rest between contractions.
How does gravity affect your blood?
Gravity affects the circulation of blood in your body by helping to return blood from your lower extremities back to your heart. When you stand upright, gravity pulls blood downwards, making it harder for your heart to pump blood against gravity. This can lead to higher blood pressure in your lower extremities and can contribute to conditions like varicose veins.
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.
How does gravity effect blood pressue?
Gravity affects blood pressure by influencing the distribution of blood in the body. When standing, gravity causes blood to pool in the lower extremities, which can lead to a decrease in blood pressure. Conversely, when lying down, gravity helps facilitate blood flow back to the heart, which can help regulate blood pressure.
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.
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
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 are the Large arteries that carry blood to the lower extremities?
The the abdominal, iliac, and femoral arteries.
Does abruptly stopping intense exercise causes blood to pool in the lower extremities?
yes
