Spiders are one of the most numerous animals. It is distantly related to insects but should not be confused. There are approximately 450 thousand species of spiders, and it is the largest group in the animal kingdom.
Only a group of spiders are dangerous; if you suspect that a spider bites you, go to the doctor.
The anatomy of spiders is something interesting to know. But to know if spiders have hearts, continue reading.
Do Spiders Have Hearts?
Sometimes, its anatomy can be confused with other insects, giving it characteristics that are not true. As an insect that arouses much interest in its structure, its internal anatomy is part of a complex system that can confuse insect bulls.
However, spiders have their characteristics, which make them unique beings within any species. These insects’ functional organism is characterized by a tubular dorsal heart, which gives life to the insect. Even the heart of spiders can generate beats that range between 30 and 100 beats per minute.
In this way, through the tracheal tubes, this organ captures oxygen and other compounds necessary to beat and give life to the insect. Your heart, perfect to meet your requirements, is an essential part of your body, allowing you to give life and pump what the rest of your organs need.
Blood circulation in spiders
Spiders have a complete circulatory system, considered an open type due to their heart and hemolymph pumping to the rest of their body. Even spiders have high pressure, which is decisive in controlling the movement of their legs. By circulating the pumped blood through all their limbs, they perform their movements smoothly.
With effective circulation, it is directly related to your respiratory organs. Undoubtedly, your body has an efficient functioning, and your blood is full of carrier cells that allow it to expand throughout your body. With efficient heartbeats and easy blood pumping, the circulatory system of spiders is complete and functional.
What Makes up the Spider Haemolymph?
To know a little more about spiders, it is necessary to define the essential liquid for your body’s functioning. The blood pumped into the body of spiders is called hemolymph. As a liquid composed of carrier cells, the hemolymph has a bluish color among its main characteristics.
Undoubtedly, this compound is responsible for the primary functioning of the spiders’ organism, being essential. It is also responsible for transporting the cells for your body’s movement, legs, and even making your respiratory system work. Without this fluid and its movement, spiders die instantly.
How do spiders accumulate oxygen?
Spiders’ complex respiratory system allows them to function efficiently and accumulate the oxygen they need. They have many aerial tubes through which the oxygen is transformed into CO2 for its operation. These tubes or conduits and transportin are found throughout the insect’s entire body to allow the necessary compound.
In hemolymph transport and composition, a compound called hemocyanin is present, responsible for carrying what is necessary to the spiders’ organs. Also, spiders and tracheas can have lungs, through which they expand and contract depending on what the insect needs from O2 to live.
In this way, the exchange and accumulation of oxygen occur within the organism of these insects, and they allow the subsistence and functioning of all their organs. With its tracheal tubes, the uptake and distribution of oxygen are carried out to have the amount within your body.
