For people over 40 years of age, on the other hand, a short check with a doctor is recommended, especially if no sport has been done … Should I see a doctor before I start endurance sports? | How can I strengthen my cardiovascular system?
How many days off between training are recommended? Ideally, there should be one to two days’ break between two training sessions. The body needs this time to regenerate and replenish its energy reserves. Those who take this time between two training units will show faster progress than with daily training.

Anatomy of the lymph vessels The lymph vessels are anatomical structures that run through the entire body like blood vessels. Just like blood vessels, lymph vessels also transport a fluid. As the name already suggests, the lymphatic fluid is transported through the lymph vessels. The anatomy of the lymph vessels is very similar to the … Lymphatic vessels
Lymph vessels of the head The lymph vessels on the head transport tissue fluid, proteins and immune cells from the head to the left vein angle. Here the tissue fluid then returns to the blood. Since the flow of lymph fluid in the head is directed downwards due to gravity and automatically returns to the … Lymph vessels of the head | Lymphatic vessels
Lymph vessels of the face Mostly lymph vessels are associated with the legs, as lymphedema can develop particularly quickly in these areas. The actual function of the lymph vessels, namely the removal of fluid, is then no longer guaranteed. But lymph vessels are also present in the face. They have the task of removing tissue … Lymph vessels of the face | Lymphatic vessels
Lymph vessels of the arm and hand Lymphatic vessel inflammation (also called lymphangitis) is usually caused by pathogens (bacteria) or other toxins (snake venom, insect venom, chemotherapeutic drugs). When pathogens or harmful substances circulating in the blood enter the lymphatic system, it often leads to inflammation of the lymph vessels or lymph nodes. Lymphangitis often … Lymph vessels of the arm and hand | Lymphatic vessels
Synonyms ArteryA artery is a blood vessel that carries blood away from the heart. In the body’s circulation, an artery always carries oxygen-rich blood, whereas in the pulmonary circulation it always carries oxygen-poor blood, since it transports the oxygen-poor blood from the heart to the lungs to enrich the oxygen. Arteries change their microscopic (histological) … Artery
Capillary Capillaries are the smallest vessels in the body and have a diameter of about 7 micrometers. They are so small that a red blood cell (erythrocyte) can usually only pass through under its own deformation. These smallest tubes consist of only one cell, which makes up the complete vessel wall. On the outside of … Capillary | Artery
Gas and mass transfer In the capillaries the mass transfer of the blood with the environment takes place. This is favoured by the very thin vessel wall and the huge total surface area of all capillaries. Some substances, such as gases, can pass through the vessel wall unhindered, while other substances are absorbed into the … Gas and mass transfer | Artery
Arteria vertebralis Dissection The dissection of an artery refers to the splitting of the inner vessel wall (intima). As a result, bleeding can occur between the intima and the media (middle vessel wall). This leads to a constriction (stenosis) or, in the worst case, to complete closure of the vessel with circulatory problems in the … Arteria vertebralis Dissection | Vertebral artery
Anatomy The arteria vertebralis is one of the vessels that supply the brain with oxygen-rich blood from the heart. Its diameter is about 3-5mm. It is arranged in pairs, i.e. there is a right and a left vertebral artery, which finally unite to form the basilar artery. This vessel mainly supplies brain sections located in … Vertebral artery
