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 →

Diabetes Mellitus – Homeostasis Ep 4

In the last article we looked at how the body uses negative feedback mechanisms to control the concentration of glucose in the blood. Diabetes mellitus is a condition where these feedback systems fail and blood glucose is not controlled, with potentially fatal consequences if left untreated. In this article we will look at the two... 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...
