What makes blood so special that it features in widespread myths? Although blood accounts for less than 10 percent of human body weight, it is quite literally the elixir of life. As blood travels through the vessels of the cardiovascular system, it delivers vital substances such as nutrients and oxygen to all of the cells and carries away their metabolic wastes.

It also mentions the heart's release of natriuretic peptides (ANP and BNP) to lower blood pressure by inhibiting renin and promoting sodium excretion.

Specifically, males have about 5.4 million erythrocytes per microliter (µL) of blood, and females have approximately 4.8 million per µL. In fact, erythrocytes are estimated to make up about 25 percent of the total cells in the body.

It explains that sickle-cell anemia arises from inheriting the βS gene from both parents, while individuals with one βS and one βA gene have some malaria resistance.
