- The blood that runs through the veins, arteries, and capillaries is known as whole blood, a mixture of about 55 percent plasma and 45 percent blood cells. About 7 to 8 percent of your total body weight is blood.t has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: 1  transporting oxygen and nutrients to the lungs and tissues. 2  forming blood clots to prevent excess blood loss. 3  carrying cells and antibodies that fight infection.

Hematocrit The hematocrit is the proportion, by volume, of the blood that consists of red blood cells. The hematocrit (hct) is expressed as a percentage. For example, a hematocrit of 25% means that there are 25 milliliters of red blood cells in 100 milliliters of blood.ormal range for hematocrit is different between the sexes and is approximately 45% to 52% for men and 37% to 48% for women.

- The hematocrit (Ht or HCT, British English spelling haematocrit), also known as packed cell volume (PCV) or erythrocyte volume fraction (EVF), is the volume percentage (%) of red blood cells in blood.It is normally 45% for men and 40% for women.ecause the purpose of red blood cells is to transfer oxygen from the lungs to body tissues, a blood sample's hematocrit—the red blood cell volume percentage—can become a point of reference of its capability of delivering oxygen.

Erythropoietin Basically, whole blood consists of red blood cells and plasma (water, proteins, etc.). The percentage of whole blood that is occupied by the red blood cells is referred to as, the hematocrit. A low hematocrit means dilute (thin) blood, and a high hematocrit mean concentrated (thick) blood.

- Capillaries have the most area. Its pretty simple. Capillaries carry blood to every cell in the body. Obviously they have the biggest surface area.Just like there are more regular streets than there are highways. NVswmmr said: ↑. I'm a bit confused regarding the relative areas of capillaries, veins, and arteries.If veins act as a reservoir and contain most of the blood, shouldn't they have the largest area? Also, capillaries are 1 cell thick, but they also have the lowest velocity. Wouldn't this mean capillaries have the largest area?apillaries have the most area. Its pretty simple. Capillaries carry blood to every cell in the body. Obviously they have the biggest surface area.

- One can estimate degrees of relatedness by subtracting the percentage of Rh-negative individuals among, say, the English (16%) from that of the Basques (25%) to find a difference of nine percentage points. The highest percentage of people with rh- blood is found in the Atlas mountains of Morocco(40%). The next highest are the Basques, reported in different publications as having 25 and 32%, depending on location.

Blood volume A typical adult has a blood volume of approximately 5 liters, with females generally having less blood volume than males.Blood volume is regulated by the kidneys. Blood volume (BV) can be calculated given the hematocrit (HC; the fraction of blood that is red blood cells) and plasma volume (PV):Blood volume measurement may be used in people with congestive heart failure, chronic hypertension, renal failure and critical care. typical adult has a blood volume of approximately 5 liters, with females generally having less blood volume than males.

Optical Absorption of Hemoglobin Hemoglobin has a normal concentration of 150g/liter of blood permits whole blood to carry 65 times more oxygen than does plasma at a PO2 of 100 mmHG. Hematocrit determines the fraction of the blood that is red blood cells. The red blood cells are primarily composed of hemoglobin (95% of the dry mass).

Guidelines for Blood Volumes in Clinical Trials (Especially in Pediatric Clinical Trials) In the rare case of simultaneous trials, the recommendation of 3% remains the maximum. The total volume of blood is estimated at 80 to 90 ml/kg body weight; 3% is 2.4 ml blood per kg body weight.. The guidelines on blood volume are usually based on the amount of blood in percentage of total blood volume (BLV).BLV varies depending on the age and body weight.ational Institute of Health Clinical Center has a guideline M95-9: Guidelines for Blood Drawn for Research Purposes in the Clinical Center, however, the guideline is only accessible for NIH internal use. Two articles from the web actually reflect the limit of blood volume in US.
