    en.wikipedia.org/wiki/Blood

    Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), [2] and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). [3]

    en.wikipedia.org/wiki/Blood_cell

    Hemoglobin is an iron-containing protein that gives red blood cells their color and facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs to be exhaled. [3] Red blood cells are the most abundant cell in the blood, accounting for about 40-45% of its volume.

    en.wikipedia.org/wiki/Blood_vessel

    Blood is 92% water by weight and the rest of blood is composed of protein, nutrients, electrolytes, wastes, and dissolved gases. Depending on the health of an individual, the blood viscosity can vary (i.e., anemia causing relatively lower concentrations of protein, high blood pressure an increase in dissolved salts or lipids, etc.). [30]

  6. Blood plasma - Wikipedia

    en.wikipedia.org/wiki/Blood_plasma

    Blood plasma is a light amber-colored liquid component of blood in which blood cells are absent, but which contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. [ 1 ]

    en.wikipedia.org/wiki/Whole_blood

    Whole blood (WB) is human blood from a standard blood donation. [1] It is used in the treatment of massive bleeding , in exchange transfusion , and when people donate blood to themselves . [ 1 ] [ 2 ] One unit of whole blood (approximately 450 mL) brings up hemoglobin levels by about 10 g/L. [ 3 ] [ 4 ] Cross matching is typically done before ...

  8. Circulatory system - Wikipedia

    en.wikipedia.org/wiki/Circulatory_system

    The heart did not pump blood around, the heart's motion sucked blood in during diastole and the blood moved by the pulsation of the arteries themselves. Galen believed that the arterial blood was created by venous blood passing from the left ventricle to the right by passing through 'pores' in the interventricular septum, air passed from the ...

    en.wikipedia.org/wiki/Red_blood_cell

    Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
