Correct Answer: 1-e, 2-d, 3-a, 4-f, 5-b, 6-c
Explanation of Each Match
- 1-e) PBMCs → Agranulocytes: PBMCs = Peripheral Blood Mononuclear Cells. This term refers to agranulocytes — i.e., monocytes and lymphocytes — which have a single, non-lobed nucleus. They are separated from granulocytes by density gradient centrifugation.
- 2-d) PMN → Granulocytes: PMN = Polymorphonuclear leukocytes (also called PML, PMNL). This term refers to granulocytes — neutrophils, eosinophils, and basophils — which have multi-lobed (polymorphic) nuclei and cytoplasmic granules.
- 3-a) Blood → Fluid connective tissue: Blood is classified as a fluid connective tissue because it has cellular elements (formed elements) suspended in a non-cellular matrix (plasma), with no solid intercellular matrix.
- 4-f) Lymph → Cisterna chyli: The cisterna chyli is a sac-like dilated lymph vessel at the junction of the intestinal lymphatics and the thoracic duct. It acts as a storage house (reservoir) for lymph, particularly chyle (fat-rich lymph from the intestine).
- 5-b) Serum → Plasma − Fibrinogen: Serum = Plasma minus fibrinogen and other clotting factors. When blood clots, fibrinogen is consumed in forming fibrin; the remaining fluid is serum.
- 6-c) Plasma → Fluid part of blood: Plasma is the acellular, liquid matrix of blood (55% of total blood volume). It contains water, proteins (albumin, globulin, fibrinogen), electrolytes, nutrients, hormones, and waste products.
