  • Gaseous Exchange Part 1

    Episode 1

    In this lesson, we look at the process of gaseous exchange and how living organisms are
    adapted to be effective in this process

  • Gaseous Exchange Part 2

    Episode 2

    n this lesson we look at gaseous exchange in the human respiratory system. We are
    going to look at the anatomy of different parts of the respiratory system and how they are adapted
    for this function

  • Gaseous Exchange : Inhalation and Exhalation

    Episode 3

    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.

  • Gaseous Exchange: Homeostasis

    Episode 4

    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.

  • Excretion: The Urinary system

    Episode 5

    In this lesson, we look at the anatomy of the organs that make up the excretory system
    and facilitate the production of waste.

  • Excretion: Ultrafiltration & Function of Urinary System

    Episode 6

    In the lesson, we take an in-depth look at the kidneys and how they process waste in our
    bodies through the process of filtration, reabsorption, tubular secretion, pH control, and urine

  • Excretion: Renal Disease

    Episode 7

    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.

  • Population ecology: Population

    Episode 8

    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.

  • Population and Ecology

    Episode 9

    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.

  • Population and Ecology: Social Organisation

    Episode 10

    In this lesson, we will look at social organizations in populations. We delve into how different species are organized and their tactics for survival.
