Explanation of Each Match
- 1-d) Neutrophils → Heterophils: In birds (avians), the equivalent of neutrophils are called heterophils. They appear morphologically different (eosinophilic granules) but function similarly as phagocytes.
- 2-c) Skin → Largest organ of the body: The skin is the largest organ by surface area and mass in most animals, including humans and domestic species.
- 3-e) Endotheliochorial placenta → Bitch (Dog): In dogs (bitches) and cats, the placenta is of the endotheliochorial type — the chorion is in contact with the endothelium of maternal blood vessels (6-layer barrier reduced to 3).
- 4-b) Epitheliochorial placenta → Sow (Pig): Pigs (sows), horses, and ruminants have an epitheliochorial placenta — the least invasive type where the chorion touches the maternal uterine epithelium (all 6 barrier layers present).
- 5-f) Inulin → GFR: Inulin (a polysaccharide) is used to measure Glomerular Filtration Rate (GFR) because it is freely filtered, neither secreted nor reabsorbed by kidney tubules, making it an ideal GFR marker. It also measures ECF.
- 6-a) Evans blue dye → Plasma volume: Evans blue dye (T-1824) binds strongly to plasma albumin and is used to measure plasma volume by the dye dilution method.
