What are the main types of circulatory systems?
Circulation system is a physiological system within organisms that are responsible for providing the necessary nutrients and gases to different parts of the body body. Different organisms can have different types of circulatory systems. Two main types of circulatory systems are an open circulation system and a closed circulation system. Vertebrates and other complex organisms tend to have a closed circulation system, while many small invertebrates have an open circulatory system.
nutrient and oxygen distribution is achieved by a closed circulation system in humans and other vertebrates. Closed circulation systems are systems in which blood or circulatory fluid is contained in a network of blood vessels that carry blood rich in nutrients and oxygen where it needs to go into the body. There are two primary parts of the human circulatory system. Lung circulation occurs when the heart pumps blood into the lungs to oxygenate the blod. In the systemic circulation of the heart pumps oxygenated blood through blood vessels into the rest of the body that needs oxygen toperforming cellular metabolism.
On the other hand, in open circulation systems, a fluid called hemolymph is present in the body cavity. To accept oxygen and nutrients, the organs bathe directly in this liquid, which is basically a mixture of blood, proteins, water, hormones, sugars, fats and other biological substances. Hemolymphs cannot be directed to specific parts of the body in open circulation systems because there is no system of blood vessels that would direct the movement of fluid. Muscle movements, as when the body moves through its environment, are generally able to move hemolymphs in the body of the body.
There are several simple organisms such as flat worms that completely lack circulatory systems of any form. NUSTINTS obtained diffuse diffuse diffuse directly into the cells that need them. Some more complicated creatures lacking circulatory systems have a highly branched digestive systemY, so the nutrients obtained can still be dispersed into cells throughout the body, even on parts that are significantly removed from the digestive system.
Circulation systemscan serve other purposes other than transporting oxygen and nutrients, especially in complex organisms. For example, blood flow in vertebrates can help control body temperature. This is particularly evident in the cold environment when the blood is heated by the inner heat of the body to the limbs. Lack of blood transport significantly inhibits this function in open circulation organisms.
