As a Transportation System

FUNCTIONS OF BLOOD
1. As a Transportation System
Transporting the results of digestive tract results in the form of glucose, amino acids, fatty acids, glycerol, various types of vitamin and mineral ions are taken from the intestine throughout the body .. Transporting oxygen (O ²) from the lungs throughout the body. O ² + oxyhemoglobin erythrocyte hemoglobin. Oxygen is released if such low concentrations in the tissue.
a. Transporting carbon dioxide (CO ²) from all over the body to the lungs.

    Carbon dioxide is absorbed into the blood (81%) and the rest as dissolved carbon dioxide
    Carbon dioxide binds to erythrocytes and combine with water to form carbonic acid, with the help of enzymes.
    Carbonic acid decomposes to form H + ions and bicarbonate ions. Then bicarbonate ions dissolved in the blood plasma of sodium bicarbonate and again in part binds to hemoglobin to form carbamino-hemoglobin.
    Diparu-lung low amount of carbon dioxide that is released and disappeared in the alveoli

b. Transporting water

    Blood transports water from the intestines and kidneys to the rest of the body that need it. Excess water will be transported by the blood to the kidneys for disposal / filter.
c. Transporting materials excretion

     That waste substances such as urea, uric acid, creatinine and others are transported to the tools excretion. excess amino acids were taken precautionary to be broken down into ammonia that works with carbon to form urea.

    Transporting hormones
Hormones produced by the endocrine glands and carried by the blood throughout the tissues that need it. example: the hormone insulin
