What do the giraffe's heart and the human heart have in common?

The main function of the heart is to pump blood throughout the body. Both giraffes and humans have two cardiovascular systems. The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation sends blood from the heart to all other parts of our body and back again.

Why is the giraffe the highest? What is the blood pressure of animals?

Kirin has a high head and, in the case of an adult, rises about 6 meters above the ground, resulting in high blood pressure. This is a long and long way for the heart to pump blood against gravity.

How long is the giraffe's heart beating?

In addition, the average resting heart rate is 40-90 beats per minute, which is slightly higher than expected for animals of that size. For comparison, this heart rate is about the same as the average human heart rate (60-100 bpm), much higher than the elephant heart rate (30 bpm).

Does the giraffe increase the number of hearts?

As with most animals, humans and giraffes have only one heart, but not all. Octopus and squid (animals called cephalopods) have three hearts. Two hearts pump blood into the gills to absorb oxygen, and another heart pumps blood around the body (Figure 1).
