17 Modules

The course on Organisms’ Exchange of Substances with Their Environment explores the physiological mechanisms by which organisms acquire, transport, and exchange substances with their surroundings. This comprehensive study encompasses the diverse strategies employed by organisms across different biological levels, from single-celled organisms to complex multicellular organisms. Students will investigate the processes of respiration, circulation, digestion, excretion, and osmoregulation, as well as the structural adaptations that facilitate these functions. Through theoretical study, laboratory experiments, case studies, and interactive learning activities, participants will gain a thorough understanding of how organisms interact with their environment to maintain homeostasis and support vital physiological processes.
