In this lesson, we are going to look at the gaseous exchange on a cellular level. We are going
to look in depth at the mechanisms of respiration from, inhalation to exhalation and how this
facilitates the movement of carbon dioxide and oxygen.
In this lesson, we look at homeostasis and how your respiratory system contributes to
the balance between gases in your body. We also delve into some of the diseases that are common
in the respiratory system and affect gaseous exchange; like TB, emphysema, and lung cancer.
In this lesson, we are looking at how the kidneys are essential in osmoregulation – the
regulation of water balance in the body. We are also taking a look at some of the disease processes
that occur in the kidney.
In this lesson, we study plants and animals and their relationship with each other in a
topic we call ecology. Our primary focus in this lesson will be population growth, regulation, and
dynamics, or demography.
In this lesson, we discuss ecosystems and how populations live in communities and interact with their environments and each other. We will take an in-depth look at the different types of interactions that exist in these ecologies.
