Kidneys are part of the lymphatic system:
True
False
The Correct Answer is B
Kidneys are not part of the lymphatic system.
The lymphatic system is a network of vessels and organs that drain excess fluid from the tissues, transport fats and immune cells, and protect the body from infections.
Kidneys are part of the urinary system, which filters blood, regulates fluid and electrolyte balance, and produces urine.
Choice A is wrong because kidneys do not have a direct connection to the lymphatic system.
Although kidneys have lymphatic vessels in their cortex, they do not originate from the lymphatic system.
Kidneys receive blood from the renal arteries and return it to the renal veins.
The lymphatic vessels in the kidney cortex drain interstitial fluid and immune cells from the kidney tissue to the regional lymph nodes.
Some additional sentences are:
Choice B is right because kidneys are part of the urinary system, not the lymphatic system.
The urinary system and the lymphatic system have different functions and structures in the body.
Normal ranges for kidney function tests include blood urea nitrogen (BUN) of 7 to 20 mg/dL, serum creatinine of 0.6 to 1.2 mg/dL, and glomerular filtration rate (GFR) of more than 90 mL/min/1.73 m.
Normal ranges for lymphatic system tests include white blood cell (WBC) count of 4,000 to 11,000 cells per microliter, lymphocyte count of 1,000 to 4,800 cells per microliter, and immunoglobulin levels of IgG (700 to 1,600 mg/dL), IgA (70 to 400 mg/dL), IgM (40 to 230
mg/dL), IgE (0 to 100 IU/mL), and IgD (0.5 to 5 mg/dL).

Correct Answer is B
Explanation
Monocytes are a type of agranulocytes, which are white blood cells that lack visible granules in their cytoplasm.
Agranulocytes also include lymphocytes, which are involved in adaptive immunity.
Choice A is wrong because basophils are a type of granulocytes, which are white blood cells that have granules in their cytoplasm.
Granulocytes also include neutrophils and eosinophils, which are involved in innate immunity.
Choice C is wrong because neutrophils are also a type of granulocyte.
Neutrophils are the most abundant white blood cells and are responsible for phagocytizing bacteria and fungi.
Choice D is wrong because eosinophils are also a type of granulocytes. Eosinophils are involved in allergic reactions and parasitic infections.
Normal ranges for white blood cells vary depending on age, gender, and health status, but generally, they are between 4,000 and 11,000 cells per microliter of blood.
Correct Answer is A
Explanation
A monocyte is a type of white blood cell that is markedly larger than a red blood cell and has a large kidney-shaped nucleus.
Monocytes are involved in defending the body against infectious diseases and foreign materials.
Choice B is wrong because a basophil is a type of granular white blood cell that has a lobed nucleus and stains purple with basic dyes.
Basophils are involved in allergic reactions and inflammation.
Choice C is wrong because a neutrophil is a type of granular white blood cell that has a multilobed nucleus and stains pale pink with neutral dyes.
Neutrophils are involved in phagocytosis and killing bacteria.
Choice D is wrong because an eosinophil is a type of granular white blood cell that has a bilobed nucleus and stains red-orange with acidic dyes.
Eosinophils are involved in combating parasitic infections and allergic responses. The normal ranges of different types of blood cells are:
Red blood cells: 4.5 to 5.9 million per microliter (mcL) for males, 4.1 to 5.1 million per mcL for females
White blood cells: 4,000 to 11,000 per mcL for both males and females
Platelets: 150,000 to 450,000 per mcL for both males and females
