Grade 11 Life Sciences
Excretion: The Urinary system
In this lesson, we look at the anatomy of the organs that make up the excretory system
and facilitate the production of waste.
Up Next in Term 3
Excretion: Ultrafiltration & Function...
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
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
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.
