Sharks have been existing for over 400 million years and have evolved to be some of the most efficient predators in the sea. However, when it comes to their heart, they have significant differences from the human heart. In this article, we will explore how a shark’s heart is different from a human heart, including its anatomy, physiology, and function.
How Shark’s Heart Is Different From A Human Heart?
There is a major difference between the sharks heart as compared to the human heart; let’s explore/start with the anatomy of a shark’s heart!
1. Anatomy Of A Shark’s Heart
The anatomy of a shark’s heart is quite different from that of a human heart. The first major difference is that a shark’s heart has two atria and one ventricle. In contrast, a human heart has two atria and two ventricles. The second major difference is that a shark’s heart is located on the side of the body, while a human heart is located in the chest.
The third major difference is that a shark’s heart has a unique structure called a spiral valve. The spiral valve is a spiral-shaped structure that helps to increase the efficiency of blood flow through the heart. This helps to ensure that the shark’s muscles and organs receive a steady supply of oxygen-rich blood.
2. Physiology Of A Shark’s Heart
The physiology of a shark’s heart is also quite different from that of a human heart. One of the main differences is that a shark’s heart is able to pump blood at a much higher pressure than a human heart. This is due to the fact that a shark’s heart has a much thicker muscle wall than a human heart.
Another difference is that a shark’s heart is able to pump blood to its gills at a much faster rate than a human heart. This is necessary because sharks need to extract a lot of oxygen from the water in order to survive.
3. The Function Of A Shark’s Heart
The function of a shark’s heart is also quite different from that of a human heart. One of the main differences is that a shark’s heart is able to pump blood to its muscles at a much faster rate than a human heart. This is necessary because sharks need to swim at high speeds in order to catch their prey.
Another difference is that a shark’s heart is able to pump blood to its gills at a much faster rate than a human heart. This is necessary because sharks need to extract a lot of oxygen from the water in order to survive.
We have covered in detail how shark’s heart is different from a human’s heart.
The Final Word
Sharks have a unique anatomy and physiology that allows them to adapt to their environment and survive in the ocean, making their heart different from humans. Their hearts are located on the side of their body, have a unique structure called a spiral valve, and can pump blood at a much higher pressure than a human heart. This makes their swimming much faster and lets them extract a lot of oxygen from the water. Understanding the differences between a shark’s heart and a human heart can help us to better understand these fascinating creatures and the ocean in which they live.
