Control of Blood Water Potential – Homeostasis Ep 6

In the first article about the kidneys, we learnt how blood is filtered and substances are reabsorbed in the Bowman's capsule and the proximal convoluted tubule. Today we will focus on the loop of Henle, distal convoluted tubule, and collecting duct, and look at how blood water potential is controlled. The loop of Henle, distal... Continue Reading →

Feedback Mechanisms – Homeostasis Ep 1

Homeostasis is the maintenance of a stable internal environment. The conditions inside the body must be stable so that cells can function properly. For example, if the temperature or pH are too high, enzymes can become denatured. It is also important to maintain blood glucose concentration and water potential, which we will look at in...

The Immune Response – Immunity Ep 1

Sometimes the body comes under attack from pathogens (microorganisms that can cause disease). If pathogens get into our body, it is down to our immune system to spring into action and destroy them. In this article we will be looking at how foreign antigens trigger our immune response, and how that results in the pathogens... Continue Reading →
