    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.).

  4. Vein - Wikipedia

    en.wikipedia.org/wiki/Vein

    In the systemic circulation, veins serve to return oxygen-depleted blood from organs, and tissues to the right heart. From here it passes to the pulmonary arteries for the pulmonary circulation to return oxygen-rich blood to the left heart in the pulmonary veins, to be pumped back into the systemic circulation to complete the cycle. Veins have ...

    The human hepatic portal system delivers about three-fourths of the blood going to the liver.The final common pathway for transport of venous blood from spleen, pancreas, gallbladder and the abdominal portion of the gastrointestinal tract [2] (with the exception of the inferior part of the anal canal and sigmoid colon) is through the hepatic portal vein.
