In this episode, we'll explore the complex dynamics of the defensive system that protects animals from the countless microbes and pathogens they encounter every day: the immune system!

In this episode, we'll explore both the chemistry and physiology of animal respiration. This will also involve a brief exploration of the cardiovascular system, which is integral to the function of the respiratory system.

The subtle but foundational relationship between form and function can be seen at all levels of biological organization, from cells to tissues to organs to limbs and body plans.

The ability to move, freely & autonomously, is one of the defining characteristics of all but the most basal animals, distinguishing them from the stationary plants, and the creeping fungi.

Animals are some of the most complex and dynamic organisms on Earth, and their mechanisms for reproduction are just as varied and complex.

An animal uses its senses to perceive and engage with the world around it, which is critical when you can move around an environment, searching for prey, and escaping predators.

All animals must eat food to survive, but how an animal eats, how often, and what it eats, play a fundamental role in the animal's evolution.

Water is critical for life. So how does the animal body use its water? How does it maintain a healthy osmotic balance, to sustain life?

Compared to plants and fungi, the animals have the most complex bodies, with the most complex body systems. Today, we'll explore the process of development that creates this complex animal body.

Today we'll be exploring the diverse and exciting ways in which Humans have used the many fungal species that share our planet.
