Question

Largest heart is of
a. Giraffe
b. Elephant
c. Crocodile
d. Lion

Answer 1

Hint: Largest heart among all animals is Blue Whale which is nearly 400 pounds, but among the land animals, when coming to the length it’s nearly two feet for giraffe, while it is 1.83 feet for elephant, then come to morphology the neck of the giraffe is tall, and it requires more power to pump the blood

Complete answer:
- In the land, one can say, that giraffe has the strongest heart, whereas the elephant heart has more weight, but the length is a little less than a giraffe
- The giraffe is the tallest animal and one can say it is approximately 5 meters tall, and the heart of the giraffe is said to be the strongest in the animal kingdom, it has multiple valves, which helps to prevent the random blood flow and to maintain normal circulation, all over the body,
- When it comes to weight, the average weight of the giraffe is up to 1200 kg and the pulse is usually 150 per min and the weight of the heart is nearly 11 to 13 kgs.
- Whereas the elephant is the largest animal on the earth, where the body weight of the elephant is nearly 6000kg, and the weight of the heart is up to 21 to 25kg, when it comes to heart rate it is very low that is averagely it is 30 per minute.
- The crocodile heart is a little complex, and it contains 4 chambers in the heart, but the circulatory system of the crocodile is a little complex
- Lion weight is approximately 400 lbs whereas the weight of the lion’s heart is nearly 1100 to 1200 grams

Hence, The correct answer is option (A).

Note: To answer the above type of questions, one should know about the important things such as the largest animal on land and aquatic life and their morphology, so if one has an idea of the weight and length of the organs such as the heart, and their physiology and all, so by comparing the options and choose according to it.
