RDW-SD is calculated as the width (in fL) of the RBC size distribution histogram at the 20% height level. This parameter is, therefore, not influenced by the average RBC size (mean corpuscular volume, MCV). [7] RDW-CV (expressed in %) is calculated with the following formula: RDW-CV = (1 standard deviation of RBC volume ÷ MCV) × 100%. [8]

Estrogen deficiency has both vaginal and urologic effects; the female genitalia and lower urinary tract share common estrogen receptor function due to their embryological development. Estrogen is a vasoactive hormone (one that affects blood pressure) which stimulates blood flow and increases vaginal secretions and lubrication.
Changes in breast size during pregnancy may be related to the sex of the infant, as mothers of female infants have greater changes in breast size than mothers of male infants. [14] Many people and even medical professionals mistakenly think that breastfeeding causes the breasts to sag (referred to as ptosis).
Oxygen (bound to hemoglobin in red blood cells) is the most critical nutrient carried by the blood. In all arteries apart from the pulmonary artery, hemoglobin is highly saturated (95–100%) with oxygen. In all veins, apart from the pulmonary vein, the saturation of hemoglobin is about 75%. [15] [16] (The values are reversed in the pulmonary ...
In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).

[1] [35] Andeans possess a similar suite of adaptations but exhibit elevated hemoglobin concentration and a normal resting ventilation. [36] These adaptations may reflect the longer history of high altitude habitation in these regions. [37] [38] A lower mortality rate from cardiovascular disease is observed for residents at higher altitudes. [39]
