Chapter 1 Flashcards
Anatomy and Physiology are about what?
Anything that is related to the human body, for example :nursing or dermatology
How do you examine the human body? What are the different ways ?
It is what a doctor does during a checkup. Cadaver dissection, Comparative Anatomy, exploratory surgery, gross anatomy,histology.
What is physiology ?
branch of biology that deals the normal functions of living things.
Robert Hooke
He made many improvements to the microscope
Anthony van Leeuwenhoek
simplified it(microscope) with a single lens
What are the characteristics of life?
Organization, Cellular composition, Metabolism, Responsiveness, movement, Homeostasis,development, reproduction, evolution of population.
What is the Hierarchy of Complexity?
Reductionism- large complex systems can be understood by studying their simpler components.
Holism-“emergent properties of the whole organism cannot be predicted from the properties of the separate parts.
What does anatomical variation mean?
No two humans are exactly alike, we are all like by 98% but our slight variation in proteins is what makes us different.
What are examples to Physiological Variation?
sex, age, diet,weight,physical activity. Any type of basic physiological values.
What are some Homeostasis and Negative Feedback examples?
If it is too warm, vessels dilate in the skin and sweating stars(heat-losing mechanism) Or
If too cold, vessels in the skin constrict and shivering begins (heat-gaining mechanism)
What is a strong example of Rapid Change and Positive Feedback?
Childbirth
What is gradient ?
A difference in chemical concentration, charge, temperature, or pressure between two points.
Matter and energy have a tendency to do what?
it tends to flow down, if it is going up then it requires spending metabolic energy.
