This depends on the external temperature of the human in question. The colder they are, the less volume is found in the extremities. However, the volume is considered high, because an injury causing blood loss in the limbs can cause someone to die in a few minutes without medical attention.

Is Stroke volume is the volume of blood in the extremities?
No. Stroke volume is the amount of blood that is pumped out of the heart with each heart beat.
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.
Why do we get blood pressure?
Pressure is necessary to circulate the blood to all extremities of the body.
How is the blood flow to extremities controlled in extreme cold?
In extreme cold, the body constricts blood vessels in the extremities, such as the fingers and toes, to minimize heat loss and maintain core body temperature. This process, called vasoconstriction, reduces blood flow to the extremities and helps to preserve heat and prioritize blood flow to vital organs. This response can also lead to numbness or tingling in the extremities due to reduced circulation.
Why is the blood flow to extremities reduced during exercise?
During exercise, blood flow to the extremities is reduced because the body prioritizes delivering oxygen-rich blood to the muscles that are actively working. The sympathetic nervous system is activated, causing vasoconstriction in the blood vessels of the extremities while promoting vasodilation in the muscles. This redistribution ensures that the essential muscles receive adequate blood supply to support increased metabolic demands during physical activity. As a result, extremities may receive less blood flow temporarily.
Where does the heart send oxygenated blood?
To the organs and extremities of the body
What does peripheral vein carry to the extremities oxygen rich or oxygen poor blood?
Oxygen poor blood
What causes poor blood circulation to the upper extremities?
Poor blood circulation to the upper extremities can be caused by factors such as blocked or narrowed arteries due to atherosclerosis, blood clots, or conditions like Raynaud's disease. Other factors may include diabetes, obesity, smoking, and certain medications. Regular exercise, a healthy diet, and avoiding smoking can help improve blood circulation to the upper extremities.
What does induced painful wounds mean?
caused by a lack of blood flow to the extremities
How are veins specialized?
Veins have valves that prevent blood from pooling up in your extremities.
What is the process blood flows through the heart to outer extremities and back?
circulation?
What is the role of the veins?
Veins carry blood from the extremities of the circulatory system to the heart.
