Meningitis is an inflammation of the meninges that can have severe effects on neurological function. Why is infection of this structure potentially so dangerous?
BSC 1005 – Lecture Notes (Unit 1) Dr. P. Bryant Chase Highlight = Important Principle Highlight = Important Concept Highlight = Key Term Chapter 1 Physiology and Movement Physiology: the science of biological function. Why learn about physiology To know how our physiological systems work, develop better understanding of our physical selves. This applies to ourselves and other people, it helps us understand similarities and unique adaptations of other animals and organisms. Homeostasis: to maintain a constant internal environment Examples: Increasing blood supply and oxygen to muscles during exercise, maintaining body temperature in cold (reduce heat loss by reducing blood flow to skin; increase heat production by shivering). Pathophysiology: changes in physiology associated with diseases: mutations, infections, etc. Learn to understand disease mechanisms, understand body response to diseases, find treatments and cures. Chapter 2 Blood Blood: part of the circulatory system. Blood is pumped by the heart through blood vessels. Heat is distributed through the blood. It is also a type of connective tissue (connects cells throughout the body as it circulates within blood vessels). Circulating blood transports molecules (O ,2CO , 2lucose) from one organ to another, and chemical signals (hormones) between cells within different regions of the body.
