PSL300 Lecture 1
- What is physiology? It is the science of how the body functions. We care more about how
things work rather than where things are i.e the study of anatomy. However, it is
important to know where things are in order to study how they work

- With reference to the case study from lecture 1:
The principle being demonstrated was homeostasis.
There is a tremendous regulation of blood pressure; the body maintains blood
pressure by involving the nervous, cardiovascular, r
molecules pressed together and spread out in one place -> creates a pressure difference

- FINISHING OFF LAST LECTURE:
Diabetics have a problem with insulin secretion and/or signalling. There are two types
of diabetics: Type 1 tends to be found in children who are not overweight. These
children develop an autoimmune di

- Case study from last time: The PTH levels are higher because of low calcium levels. The
calcitonin levels will be low because there is low calcium in the blood. The cause is a
genetic defect in the calcitriol receptors; although c

- Last lecture:
Conns syndrome too much aldosterone so there is a tumor in the glomerulus (part
of adrenal cortex that makes aldosterone); this means that potassium is lost in the
urine and retaining sodium, weakness in muscles, hyper
