Lecture 2 Flashcards
What is health?
A state of complete physical and social well- being and not merely an absence of disease or infirmity
How can we strive to achieve health?
- everyone has equitable information and access to health care
- striving to have the same amount/access to medical and health care as everyone in the world
-element of cooperation between government and health care workers
What are the 7 characteristics of life?
- Responsiveness to the environment
- Growth and change
- Ability to reproduce
- Have a metabolism and breathe
- Maintain homeostasis
- Being made of cells
- Passing traits onto off springs
Each adult human can be considered as a unique biological system, why?
- Our emergent properties as an adult human make us unique, despite our remarkable genetic similarity to other species
The control and communication network
What coordinates our function (ie networking) in the adult human biological system
Central nervous system
- Made up of the brain and spinal cord
(part of the CCN)
The peripheral nervous system
-Somatic (voluntary) nervous system
-Autonomic (involuntary) nervous system
(part of the CCN)
The endocrine system
-Endocrine tissues and exocrine glands
- Hormones
(part of the CCN)
The support and defense systems
-Support, movement, maintenance, repair, adaptation, defenses (non-specific and specific)
Properties of the CNN
-It controls and coordinates the function of all physiological systems and individual organs, including itself
-It is always on (even in vegetative state)
- It is distributed throughout the entire body
-Each component of the network has multiple functions; the network has redundancy
- Information flow within the network is via chemical-based, cell-cell communication
-(the mind is not separate from the body)
The CNN is the integrator of inputs to:
-Health, disease, and aging - genetics environment and lifestyle
-the 7 dimensions of health
Aging and disease are processes which represent compromised function/structure of the CNN
-Many disease processes which represent compromised function/structure of the CCN
-There is a reduced function of the CCN with aging
