The octopus has a closed circulatory system, and blood remains in the blood vessels. The octopus has three hearts. A whole-body heart that circulates blood around the body and two gill hearts that pump blood to each of the two gills. The whole body heart is inactive when the animal is swimming, so it prefers to crawl tired quickly. The octopus basically has a brain at the base of each arm and is connected to the larger central brain. Not only does the octopus have nine brains, but the octopus has three hearts and blue blood, making it look like another world. Why does an octopus have nine brains? Losing both branched hearts means that the octopus cannot get blood through the gills and oxygenate it. If you lose one and the main heart, the octopus can pump blood and oxygen to one heart, but not the rest of the body. Brachiopods have black blood. Octopus blood looks blue because it has copper-based blood called hemocyanin, which absorbs and reflects all colors except blue. May 24, 2018 How long will an octopus live if it does not mate?
worldatlas.com Изображение: worldatlas.com The answer to both questions is yes — if you are an octopus. Octopus needs all three hearts to circulate blood in the body. Two of the hearts are called branched hearts. They sit just behind the eyes and connect to the gills of the octopus, where oxygen enters the blood.
How many hearts are there in the octopus?
Two hearts, called gill hearts, are located near each of the two gills of an octopus. They pump blood through the gills of the octopus. The third heart (called the whole body heart) is the body that pumps oxygenated blood to the rest of the heart. Do octopuses need all three hearts to survive?
Does the octopus have a brain?
Yes, the octopus has nine brains, eight arms, three hearts, and blue blood. In addition to the central brain, each arm has a mini-brain that allows it to move independently. Two hearts pump blood to the gills, and a larger heart circulates blood to the rest of the body.
What if the octopus loses the gill heart?
Losing the heart of both gills means that the octopus cannot get blood through the gills and oxygenate it. Losing one and the main heart means that the octopus may be able to pump blood into one heart and supply oxygen, but it cannot pump blood to the rest of the body. increase.
What kind of blood does an octopus have?
Octopus blood contains hemocyanin, a protein rich in copper. Hemocyanin is more efficient than hemoglobin in transporting oxygen at very low temperatures and low oxygen concentrations. Octopus is a cephalopod along with squid, squid and nautilus. Most of the hundreds of cephalopods have three hearts.
