Question

Which animal has an oval-shaped RBCs?
A. Humans
B. Camel
C. Dog
D. Fish

Answer 1

Hint: RBC is the red blood cell or erythrocytes or erythroid that helps to transport oxygen invertebrates.

Complete answer: The shape of the human red blood cell is known to be a biconcave disc.
1. The shape of the dog red blood cell is large, uniform, biconcave disc.
This is reflected in Wright's stained blood film as a cell with an area of central pallor.
2. The shape of Red Blood Cells of fish species studied varies from oval to ellipsoid and a rounded nucleus.
3. The red blood cells of the camel are oval-shaped that protect it from dehydration because the oval-shaped cells can circulate even in thick blood and can significantly expand during rehydration. The hemoglobin of the camel also has a higher affinity for oxygen than other domestic mammals.

So, the answer is B. Camel

Note: The camel’s red blood cells are capable of expanding up to 240% of their original volume without rupturing; most animals’ cells can expand only 150%. This makes it possible for the camel to drink the necessarily large amount of water to recover from dehydration. This allows the camels to drink up to 30 gallons of water in 13 minutes to recover from dehydration. This elongated shape of their red blood cells also allows the ease of traveling in thick blood and narrow blood vessels during dehydration.
