1. The right answer is assist.
The lymphatic system is very important for the nutrition of our cells. This system, which is part of the circulatory system, is not an independent part of the body. It is made up of lymph, a fluid derived from blood that returns to the blood through the lymphatic vessels. The lymph carries some of the nutrients in the body, including lipids.
2. The right answer is exchanges.
The substances are transported by the blood into the different tissues of the body. The exchange of substances between the blood and the tissues takes place mainly at the level of the capillaries. It is indeed in the very branched capillary bed that the exchange surface is the largest and the longest exchange time (low speed of blood flow). The capillary wall is also a barrier between blood and tissue. It is formed of a layer of endothelial cells surrounded by a basement membrane.
3. The right answer is collect.
The lymphatic system is composed of a large network of lymphatic vessels. These are arranged in parallel with certain blood vessels. They are present in many tissues of the body, except the nervous system, bone marrow, cartilage and muscles. Each vessel connects tissue to a lymphatic organ.
4. The right answer is veins.
The lymph, an interstitial fluid circulating in the lymphatic vessels, takes care of some of the waste of cellular activity via the intercellular tissues. The lymph is purified by passing through the ganglia. It then circulates to the bloodstream, which is joined by the thoracic duct at the level of the subclavian veins.
5. The right answer is lymph.
The lymph is a colorless or slightly yellowish biological fluid circulating in the lymphatic vessels, which run through the entire human body. This liquid contains a plasma close to that of blood. It contains white blood cells, including lymphocytes, hence its main action in the defense of the body. The lymph is however devoid of red blood cells.
