Anatomy And Physiology-lesson 1 Part 1 Flashcards
Body Organization
What are the 5 body cavities?
Cranial, spinal, thoracic, abdominal, pelvic cavity
In regards to the 5 body cavities, what organs are contained in them and what separates them.
Cranial and spinal–>lining and mengines
Thoracic - - >heart and lungs, plural membranes and pericardial membranes abdominal and pelvic cavities
–>protected by bones!!
Abdominal–> liver, stomach and intestines, peritoneum and mesentery
–>NOT protected by bones!!
Pelvic–>bladder and reproductive organs and covers free surfaces of several organs
Define homeostasis. What are it’s control mechanisms?
A state in which the internal environment of the body remains relatively stable by responding appropriately to changes.
It’s control mechanisms are…
How is the abdomen described for nursing assessments?
The 4 quadrants:RUQ, LUQ, RLQ, LLQ
right, left, upper, lower
Hypo
Slower
Hyper
Faster
What is the universal carrier of energy in the body?
ATP
Aerobic cellular respiration
Requires oxygen
Anaerobic
Does not require oxygen
Mitosis
Process of cell division in which one cell with the diploid # of chromosomes divides once to form 2 identical cells, each with the diploid # of chromosomes
Mieosis
Process of cell division where one cell with the diploid number of chromosomes divides twice to form 4 cells, each with the haploid # of chromosomes: forms gametes
Difussion
Movement of molecules from an area of GREATER concentration TO area of LESSER concentration
Active transport
Uphill movement of a substance thru a living cell membrane (lower conc. - - >higher conc.)
**Requires energy of ATP
Glutial region
Buttocks
Aduction
Movement to the midline of the body
Anticubital
The front of the elbow
What part of the body is a beef tenderloin?
Skeletal muscle
Isotonic
A solution with a Salt concentration equal to that in the cell (happy cell)
