The study of the human body
• Anatomy – The study of the structure of the body
• Physiology – The study of the function of the body
• Understanding the normal body is basis for analyzing disease
• Pathology – The study of disease processes in the human body
![Page 5: Required Media/Equipment/Software:](https://reader035.fdocuments.net/reader035/viewer/2022062812/568163f6550346895dd58496/html5/thumbnails/5.jpg)
Levels of Organization:
Chemicals -living matter is derived from simple
chemicals
Cells – basic unit of biological organization; performs all the
activities necessary to maintain life
Tissues – a specialized group of cells form tissue;
4 types – muscle, nerve epithelial and connective
Organs – organized tissues functioning together
Systems – a group of organs that perform a
common function

Metabolism• Metabolism includes all life sustaining reactions that go on in the
body• Consists two types of activities:
– Catabolism – complex substances broken down into simpler compounds to deliver energy– Anabolism – the building phase of metabolism (for growth, tissue repair, function)
• ATP – adenosine triphosphate - energy unit the body uses
![Page 29: Required Media/Equipment/Software:](https://reader035.fdocuments.net/reader035/viewer/2022062812/568163f6550346895dd58496/html5/thumbnails/29.jpg)
Homeostasis• Maintenance of the internal environment of
the body• Body temperature, body fluids, heart rate, blood pressure, etc must be kept within
set limits to maintain health This steady state within the organism is
called Homeostasis • Homeostasis is maintained through
balance of intracellular and extra cellular fluids and a series of feedback loops
![Page 30: Required Media/Equipment/Software:](https://reader035.fdocuments.net/reader035/viewer/2022062812/568163f6550346895dd58496/html5/thumbnails/30.jpg)
Fluid balance
• Extracellular fluid:– Transport nutrients into and out of the cell– It includes all body fluids outside the cells– Example: blood, interstitial fluid
• Intracellular fluid:– Contained within the cell
![Page 31: Required Media/Equipment/Software:](https://reader035.fdocuments.net/reader035/viewer/2022062812/568163f6550346895dd58496/html5/thumbnails/31.jpg)
Feedback• Is a control system based on information
returned to the source• Negative Feedback Loop – most body systems
are regulated this way – An action causes the body to reverse the trend of that
action– Examples include temperature regulation: Body
temperature rises, alerting the brain, causing sweating and other cooling mechanisms
• Positive Feedback Loop – An action produces more of the same action– Examples include childbirth: stretching the uterus
causes contraction of the uterus causes stretching…
