Introduction

´╗┐describe the structure and purpose of the lymphatic system The lymphatic system is a network of small tubes that has the function of an extensive drainage system. This drainage network helps keep the body intact by keeping body fluid levels balanced so that the body can fight infections effectively. The small tube system that is present in the body drains lymph fluid from all over the body. Lymph tissues are scattered all over the body in many major organs. Places in the body such as the heart, the lungs, liver, intestines, skin, spleen, bone marrow, thymus glands, tonsils and lymph nodes are all places that lymph nodes are present. Lymph nodes are also present in the body that can be found in the groin, armpits, neck, abdomen areas, chest, and pelvis. These lymph nodes are identified and separated from the tissues in the body due to its structure. The lymph nodes have a round doughnut shaped structure. The function of this particular complex system is to collect lymph fluid from the tissues and the body and return this back to the blood. If excess fluid that constantly leaks from the tiny blood capillaries was not removed then this fluid would build up around the surrounding body tissues, this could potentially prove to be very dangerous. ...read more.

The white pulp: made up of mainly lymphocytes and has a circular structure. M5- Explain how the lymphatic system protects the body The lymphatic system is made up of many different vital specialized cells, each of these cells play a role in protecting the body. The system also contains proteins tissues and organs these all help to fight off micro- organisms and protect the body again these micro-organisms. The specialized cells within the lymphatic system defend the body against invasion off viruses, bacteria and fungi. These are known as agents that could possibly cause diseases. These harmful materials are filtered out in the lymphatic system by a small mass of tissue that is also known as the lymph node. The lymph node lies along the network of the lymphatic system. The lymph nodes within the lymphatic system contain white blood cells; the white blood cells are housed by these nodes. The white blood cells contained within also produce specialized antibodies. These antibodies fight off infection, and stop the spreading off an infection by being able to catch the germs and kill them. These germs are what will cause the disease at a later stage. Another part of the lymphatic system that helps to fight off an infection is the spleen. ...read more.

Conclusion

Lymphedema is one of the most common lymphatic disorders it can also be known as a lymphatic deficiency. This disorder is where they body cannot filter the lymphatic fluid through areas such as the arms and chest properly. This is due to the absence of the lymph nodes. Swelling also becomes visible, which contains trapped fluid of bacterial infection that can lead to cellulites and sepsis. There are two stages to this disorder primary and secondary. Primary Lymphedema is an inherited part of the disorder that occurs when there are missing or impaired lymphatic vessels. Primary Lymphedema affects at least up to four limbs at a time. Secondary Lymphedema also known as lymphatic deficiencies occur due to an infection after surgery or due to a trauma. Surgery is the main cause as it disrupts the regulation of the lymphatic vessels or can cause a loss in the lymph nodes. Lymphangioleiomyomatosis is also another disease caused by the lymphatic system this however is a very rare disease that can cause lung cancer. This type of disease results in disorderly muscle growth in the lymphatic areas. These two are one of many diseases caused by the lymphatic system. The lymphatic system plays a vital role in the body and if this system is not working properly it could prove to cause very dangerous diseases. ...read more.

    The valves are held in place by valve tendons ("heart strings") attached to papillary muscles, which contract at the same time as the ventricles, holding the vales closed. There are also two semi-lunar valves in the arteries (the only examples of valves in arteries) called the pulmonary and aortic valves.

    The placenta is responsible for the heightened progesterone levels in the cow, which indicates on-going pregnancy. When the gestation period is up, or the calf is getting too big for the womb, the fetal calf starts sending stress signals through the placenta to the cow's brain, which signal the uterus to start labour contractions.
