vérellátásúak

Vére­llátásúak is a Hungarian term that translates to "blood-fed ones" or "those with blood supply." It refers to a group of organisms that possess a circulatory system responsible for transporting blood or a similar fluid throughout their bodies. This system is crucial for delivering oxygen, nutrients, and hormones to cells and for removing waste products.

The concept of vérellátásúak encompasses a wide range of animals, from simple invertebrates with open circulatory systems to complex vertebrates with closed circulatory systems. In an open circulatory system, blood is not always contained within vessels and bathes the organs directly. In contrast, a closed circulatory system features a network of blood vessels that continuously circulate blood.

The presence of a vérellátású system is a significant evolutionary development, allowing for larger body sizes and more complex metabolic processes. The efficiency of nutrient and gas exchange is greatly enhanced by this specialized system. The study of vérellátásúak falls within the broader fields of zoology and comparative physiology, examining the diversity and evolution of circulatory systems across the animal kingdom.
