The effect of massage on the circulatory and lymphatic systems

The effect of massage on the circulatory and lymphatic systemsThe main function of the circulatory system is to ensure the exchange of substances between the tissue and the external environment: the oxygen supply of energy and nutrients and removal of metabolic products. The circulatory system consists of big and small circles of blood circulation. In the big circle of blood circulation arterial blood from the left ventricle enters the aorta, arteries, arterioles, capillaries, venules, veins. In the pulmonary circulation of the venous blood from the right ventricle enters the pulmonary artery, arterioles and capillaries of the lungs where it is oxygenated and pulmonary veins flows into the left atrium. Muscles are Contracting, result in the movement of venous blood. The veins are special valves that provide translational movement of blood to the heart and prevent the reverse current. The speed of blood in the veins is lower than in the arteries. The pressure of venous blood slightly. The main function of the lymphatic system is the absorption of water from the tissues, colloidal solutions of proteins, emulsions, fatty substances, foreign particles and bacteria. It consists of a dense network of lymphatic vessels and lymph nodes. The total number of lymphatic vessels is many times greater than the number of blood vessels. They form two lymph trunk, which flow into a large vein near the heart. Lymph bathes all the cells of the body. Its movement is due to the higher pressure in the lymphatic vessels than in blood, the presence of a larger number of valves prevent the reverse current, the contraction of surrounding skeletal muscles, the suction action of the chest when breathing and pulsation of the large arteries. The speed of movement of lymph 4 MMS. Chemical composition similar to blood plasma. Fig. 2 Lymph nodes play a very important for body function, called the barrier. They are a kind of mechanical and biological filters, through which lymph is freed from suspended therein Particles. In addition, lymph node lymphocytes are formed, destroying them falling into the infectious bacteria and viruses. Lymph nodes - a collection of lymphoid tissue. Their value is from 1 to 20 mm Are no groups on the lower limbs (inguinal, femoral, popliteal), chest (armpit), upper extremities (elbow), neck (cervical), the head (occipital and submandibular). The movements during the massage of the hands should be orientated in the direction of lymph flow, in the direction of nearby lymph nodes (Fig. 2, 3): - when the head and neck massage from top to bottom, to subclavian nodes; - massage of the upper extremities to the elbow and axillary nodes; - when you massage the breast from the sternum in hand, to axillary nodes; - massage of the upper and middle part of the back of the spine to the side, to padmasani cavities; - when you massage the lumbar and sacral region of the back - to inguinal nodes; - massage of the lower extremities to the popliteal and inguinal nodes. Fig. 3 Under the influence of massage is the acceleration of movement of all liquid media of the body, especially the blood and lymph, And this takes place not only on the massaged area of the body, but also in remote veins and arteries. So, a foot massage can cause redness of the skin of the head. Of particular note is the effect of massage on skin capillaries, which carry out the exchange of substances between blood and surrounding tissues (lymph). Massage capillaries open, and the temperature massaged and surrounding areas of the skin is increased from 0.5 to 5 degrees, which improves redox processes and more intensive supply of tissue with blood. Occur when you massage the expansion of the capillary network of the skin and improve venous circulation facilitate the work of the heart. Massage in some cases may cause a small increase in blood pressure and an increase in the number of platelets, leukocytes, erythrocytes and hemoglobin. But in the short time after the massage, the Blood returns to normal, and blood pressure decreases. Even the most simple and does not require special efforts massage techniques such as effleurage, can cause draining lymphatic vessels and accelerate lymph flow. As friction or percussion techniques can result in significant enlargement of the lymphatic vessels. Massage lymph nodes is not possible. Increased lymph flow when swollen and painful lymph nodes may lead to the spread of infection in the body..
