Plasma
People who weigh more do not normally have more blood volume. This is because what makes people overweight is fat not blood.
When the heart pumps blood around the body it makes more blood available to all parts of the body, including the muscles
Blood volume has more to do with weight than sex.
BLOOD PLASMA is the yellow liquid component of blood, in which the blood cells in whole blood would normally be suspended. It makes up about 55% of the total blood volume. It is mostly water (90% by volume) and contains dissolved proteins, glucose, clotting factors, mineral ions, hormones and carbon dioxide (plasma being the main medium for excretory product transportation)
As a person grows from infancy to adulthood, the total blood volume increases. The larger an individual is, the more total blood volume they have.
Actually 55% of blood volume
Your body makes more blood everyday.
During pregnancy, a woman's blood volume increases by about 40-50 to support the growing fetus and placenta. This increase in blood volume helps provide more oxygen and nutrients to the developing baby.
Perhaps your systemic blood supply has decreased because more blood is acting to bring more oxygen/nutrients to where you've been wounded (i.e., your stomach). What method was used to measure your blood volume?
Salt affects blood pressure because it can cause the body to retain water, leading to an increase in blood volume. This increased blood volume puts more pressure on the walls of the blood vessels, resulting in higher blood pressure.
regulated by the osmolality of the circulating blood. Osmolality refers to the concentration of dissolved chemicals (such as sodium, potassium, and chloride; together called solute) circulating in the fluid base of the blood
Because when you excersise your blood heart is pumping more blood so then it makes you breathe more.
