Physiology Flashcards
(12 cards)
The major determinant of the resting potential of all cells is?
K+ gradient between the blood and interstitial fluid.
What is physiology?
The science of the body and their functions.
Cells?
Structural and functional unit of an organism ( building blocks of the human body)
Physiology is an?
Interdisciplinary science with many levels of organization.
Tissues?
Groups of cells that are similar in structure and perform a related function.
How many types of main tissues are there?
There are 4 main types of tissues. Epithelial covering) Connective(support) Muscle (movement) Nervous(control)
Organs?
Groups of tissues that combine and perform a specific function.
Organ systems?
A group of organs working together to perform a specific function.
What is the nervous systems main function?
The control and communication of the body systems.
When an atom of an element gains or loses one or more electrons, it is called?
An ion of that element.
If the Na+ chemical gradient between the ICF and the ECF diminishes to zero, what is the most likely predicted effect on the resting membrane potential of a cell?
The resting membrane potential of a cell will eventually reach the equilibrium potential of K+.
How does the body maintain a fairly constant internal environment?
Homeostasis
