Introduction:
Lymphatic system comprises of cells, tissues and other organs which defend our body against infections and disease. It is also comprised of lymph-a clear fluid which is found outside the cells. Lymphatic system has lymphatic capillaries, vessels, ducts, and trunks. Lymphatic system is also comprised of lymphatic tissues or organs like, tonsils, lymph nodes and nodules, spleen, and MALT.
Answer to Problem 1DYKB
Correct answer:
The lymphatic system is a part of the circulatory system and immune system that have interconnected lymphatic vessels which contain a clear fluid called lymph. Therefore, option b. is correct.
Explanation of Solution
Reason for the correct statement:
Option b. is given as “cardiovascular and immune”. The circulatory and immune systems are supported by the lymphatic system. The lymphatic fluid is consists of immune system cells that protect against infection and also the circulatory fluid blood is filtered by the spleen. Hence, immune and cardiovascular systems are the body systems which are supported by the lymphatic system.
Hence, option b. is correct.
Reasons for the incorrect statements:
Option a. is given as “cardiovascular and urinary”. Lymphatic system supports cardiovascular system but does not have any role with the urinary system. Hence, option a. is incorrect.
Option c. is given as “respiratory and cardiovascular”. Lymphatic system supports cardiovascular system but it does not supports the respiratory system. Hence, option c. is incorrect.
Option d. is given as “respiratory and urinary”. Lymphatic system supports circulatory and immune systems in body but does not have any function in either respiratory or urinary system. Hence, option d. is incorrect.
Hence, options a., c., and d. are incorrect.
Lymphatic system supports both circulatory and immune systems as they are interconnected. Lymphatic system provides immunity to cells, tissues and other organs which helps to defend the body against infections and disease. Lymphatic system also returns the fluid leaked from the blood back into the circulation.

Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele.
