Animal Essential Functions

The video tutorial explores the seven essential functions of animals: feeding, respiration, circulation, excretion, response, movement, and reproduction. It details various feeding strategies like herbivory, carnivory, and parasitism. Respiration is explained as the process of oxygen intake and carbon dioxide expulsion, with examples like gills in fish. Circulation involves the distribution of oxygen and nutrients, while excretion removes waste. The nervous system governs response, and movement is facilitated by muscles and skeletons. Reproduction is discussed in terms of sexual and asexual methods, highlighting genetic inheritance.
