5. What kind of crystals can be seen in animals with ethylene glycol toxicity?

Ammonium biurate

Monohydrate calcium oxalate

Amorphous urates

Animals with ethylene glycol toxicity can develop crystals of monohydrate calcium oxalate. Ethylene glycol is metabolized in the liver to oxalic acid, which then combines with calcium to form calcium oxalate crystals. These crystals can accumulate in the kidneys and can cause damage to the renal tubules, leading to acute kidney injury. Therefore, the presence of monohydrate calcium oxalate crystals in the urine is indicative of ethylene glycol toxicity.

8. What are these? ?

These are different names for the same type of blood cells found in the human body. Red blood cells, also known as erythrocytes or RBCs, are responsible for carrying oxygen from the lungs to the rest of the body and removing carbon dioxide. They are disc-shaped cells that lack a nucleus and contain a protein called hemoglobin, which gives them their red color. The multiple names provided in the answer simply refer to the same type of blood cells.

14. What is labeled in yellow?

The yellow label in the image is indicating the presence of White Blood Cells (WBCs), also known as Leukocytes. WBCs are a crucial part of the immune system and help to fight off infections and diseases. They play a vital role in defending the body against harmful pathogens and foreign substances.

15. What kind of cell is this?

This cell is a squamous epithelial cell. Squamous epithelial cells are flat, thin, and scale-like in shape. They form the outermost layer of the skin and line the cavities and surfaces of organs throughout the body. These cells are responsible for providing protection, acting as a barrier against pathogens, and facilitating the exchange of gases and nutrients. Squamous epithelial cells are commonly found in the skin, lungs, and blood vessels.

16. What is marked in purple?

The correct answer is RBCs, which stands for Red Blood Cells. These cells are responsible for carrying oxygen throughout the body and removing carbon dioxide. They are typically round and have a reddish color due to the presence of hemoglobin. By marking them in purple, it is likely that the intention is to highlight their importance in the given context.

22. Which crystals can form in Alkaline urine?

Amorphous phosphates

Calcium Oxalate

Struvite

Amorphous urates

Ammonium biurate

Cystine

Triple Phosphate

Crystals can form in alkaline urine due to the presence of certain substances. Amorphous phosphates, struvite, ammonium biurate, and triple phosphate are all types of crystals that can form in alkaline urine. These crystals are formed when the pH of the urine is high, causing certain minerals and compounds to precipitate out of the urine and form solid crystals. Calcium oxalate, cystine, and amorphous urates, on the other hand, are more likely to form in acidic urine.

What kind of cell is marked in white?

The white marked cell is most likely a Renal Tubular Epithelial Cell. This is because renal tubular epithelial cells are a type of epithelial cell found in the renal tubules of the kidneys. Epithelial cells are a type of cell that line the surfaces and cavities of the body, and they serve various functions such as protection, absorption, and secretion. Therefore, it is reasonable to assume that the white marked cell in this context refers to a renal tubular epithelial cell, as well as any other type of epithelial cell that may be present.
