Concept explainers
To determine:
The lymphatic organ that a doctor would be checking just below the rib cage, on the left side of a patient’s body who is suffering from mononucleosis and explain that why it would show enlargement along with the anatomy and histology of the organ.
Concept introduction:
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. Lymphatic system comprises lymphatic capillaries, vessels, ducts, and trunks. The lymphatic system is also comprised of lymphatic tissues or organs like, tonsils, lymph nodes and nodules, spleen, and MALT. Tonsils function as filters in the body. They trap the foreign particles ingested in food or drink or inhaled through the air and protect the body against pathogens.

- It sometimes is difficult to distinguish the different lymphoid organs from one another in histological sections. How would you tell the thymus from a lymph node? (a) Only the thymus has a cortex and medulla; (b) lymphocytes are far less densely packed in the thymus than in the lymph node; (c) the thymus contains no blood vessels; (d) only the thymus has distinct lobules and thymic corpuscles.arrow_forwardSylvia’s grandfather is diagnosed with lung cancer. When his physician takes biopsies of several lymph nodes from neighboring regions of the body, Sylvia wonders why, since his cancer is in his lungs.

Lymphatic vessels constitute a one-way system that delivers fluid from the blood vessels to the extracellular space. b. Lymph from the lower limbs drains into the right lymphatic duct. c. Fat-containing lymph from the intestines drains into the cisterna chyli. d. The thymus is the site of maturation of B cells. e.
