A) Dog: 7-9%, Cat: 5-7%, Horse: 8-10%
B) Dog: 10-12%, Cat: 8-10%, Horse: 12-15%
C) Dog: 15-17%, Cat: 10-12%, Horse: 18-20%
D) Dog: 20-22%, Cat: 15-17%, Horse: 25-30%

Answer 1

The percentage of body weight made up by blood volume is 7-9% for dogs, 5-7% for cats, and 8-10% for horses, with blood plasma comprising a significant portion of this volume.

Step-by-step explanation:

The percentage of body weight that is comprised of blood volume varies among different animal species. For dogs, this range is between 7-9% of their body weight, contributing to their overall circulatory system functions. Cats, being smaller, have a slightly lower percentage range of 5-7%, while horses, with their larger size, have a blood volume constituting 8-10% of their body weight. This is significant in understanding how to treat and maintain the health of these animals, especially in veterinary practice and research. Considering blood plasma is about 92 percent water, and is a significant component of this blood volume, hydration and fluid balance become crucial to the overall health of these animals. Dogs are estimated to have approximately 80-90 ml of blood per kg of body weight, emphasizing the importance of weight in determining blood volume.
