3 Option 2 – HS130-05 Discuss the morphology of the lymphatic system. Also‚ compare B and T lymphocytes and their roles in immunity. The lymphatic system is responsible for helping the human body fight against diseases and illnesses. This system consists of ducts‚ organs and nodes and transports fluid called lymph. The system contains cells called lymphocytes. Lymphocytes protect the body from antigens. The ducts of the lymphatic system are the home for B-cells and T-cells‚ these ducts also

The two organ systems in the human body I chose were the lymphatic system and the integumentary system. The lymphatic system is there to help fight off diseases and is vital part of the immune system. Integumentary system function is to protect you against infection and other homeostasis. They both play an important role within the human body because we need to protect

clusters that cannot pass through the blood vessels. The reaction occurs from the complement system when the person receiving the blood has a rare protein on their blood cells. So antibodies to this certain antigen are not present until after the patient is exposed to the blood. This is why all blood is typed‚ crossed‚ and then cross-matched with the potential recipients’ blood. 4. Our lymphatic systems have several jobs‚ from body tissues it removes extra fluids‚ it produces immune cells‚ it helps

Compare the Circulatory system and the Lymphatic system Closely connected with the blood and circulatory system‚ the lymphatic system is an extensive drainage system that returns water and proteins from various tissues back to the blood stream. When blood reaches the arterial end of the capillary beds in the body tissues‚ fluid from the plasma is forced out of the capillaries by the blood pressure in to a space between the capillaries and the tissue cells. This fluid‚ called tissue fluid‚ is plasma

Abstract: This paper will breakdown and define the meanings in medical terminology. Using the Lymphatic and Immune Systems as examples‚ the root‚ prefix and suffix will be identified and analyzed to show how to determine the definitions and meanings of the medical terminology terms. You are a front office medical assistant. A second front office medical assistant is going to be hired‚ and you have been asked by the office manager to help her screen job applicants for the position. The office

Fluid balance. The lymphatic system is a linear network of lymphatic vessels and secondary lymphoid organs. About 30 Litter of fluid pass from the blood capillaries into the interstitial fluid each day‚ 27 Litter pass from the interstitial fluid back into the capillaries. If the remaining 3 Litter of fluid were to remain in the interstitial fluid‚ edema would result‚ causing tissue damage and eventual death. Instead‚ the 3 L of fluid enter the lymphatic capillaries‚ where it is called lymph and passes

pressure. The lymphatic system picks up fluid that leaks out of the capillaries and returns it to the circulation. Lymphatic capillaries start in capillary beds Lymphatic capillaries snake their way through capillary beds to pick up the excess fluid and return it back to the venous circulation. As fluid pressure increases‚ it forces open little flaps in the lymphatic capillaries‚ and the excess fluid enters the lymphatic system. Lymphatic Vessels Lymphatic capillaries lead to lymphatic vessels
