NURS207 Exam With All Questions And CorrectAnswers A+ Graded
Anatomy - The process of learning the structures of the body and the relationship
between them. Dissections or medical imaging are used to show detailed structures of
the human body. Physiology - A study of the functions of the body. It explains how the
body would react to certain stimuli and how it would work. Pathophysiology - A study of
how disease processes affect the function of the body. Cranial Cavity - The cavity
contains the brain within the skull and even parts of the spinal cord.
thoracic cavity - Answer includes heart, lungs
abdominopelvic cavity - Answer includes both abdominal and pelvic cavities
- includes the organs within these cavities
intracellular fluid - Answer fluid inside of cells
extracellular fluid - Answer fluid outside of the cell
total body mass - Answer lean tissue mass plus fat mass
- in females - 45% solid, 55% fluid
- in males - 40% solid, 60% fluid
electrolytes in fluid- Answer make cells more excitable and can respond to stimulus that
need to carry out a specific function
-intracellular fluids contain potassium
-extracellular fluids contain more sodium and chlorine
Cells- Answer collection of molecules enclosed by a cell membrane
,Tissues- Answer collection of cells with structural and function specializations
Organs- Answer collection of tissues with a structure and function
Integumentary system- Answer Comprise skin, mucous membranes, hair, and nail
- protect the body, maintain temperature and senses stimulus from the external
environment
blood circulatory system- Answer heart, blood vessels, lymphatic vessels and nodes,
spleen, thymus gland
- transport material maintaining pressure gradient necessary for exchange within the
body, for immunity
respiratory system- Answer Comprise the nasal cavity, airway and lungs
- transport gases between internal and external environments
Digestive System - Answer Mouth, pharynx, oesophagus, stomach, intestine, galbladder
- Ingested and broken down food particles for the purpose of absorption
Renal System -Answer Kidney, ureters, bladder, urethra
- maintain fluid, electrolytes, production of eryhtrocytes
Endocrine System -Answer Glands secrete hormones that regulate processes such as
growth, reproduction, and nutrient use (metabolism) by body cells.
Immune System -Answer Thymus, spleen, lymph and leukocytes
- defense against foreign invaders
,nervous system-Answer the network of nerve cells and fibers that transmits nerve
impulses between parts of the body.
- brain, spinal cord, peripheral nervous system
musculoskeletal system-Answer the system of bones and skeletal muscles that support
and protect the body and permit movement
- used for support
reproductive system-Answer ovaries, uterus and testes
- produces offspring
Homeostasis -Answer to maintain nearly constant conditions in the internal environment
state of equilibrium with respect to bodily functions and chemical composition
Maintained through a feedback mechanism of positive and negative
positive feedback - A reinforces the stimuli, increasing in intensity, sending the variable
farther from the setpoint
negative feedback - A decrease in function in response to a stimulus
shuts down the respond loop
three parts of the cell - plasma membrane, cytoplasm, nucleus
plasma membrane- Answer highly selective permeable membrane enclosing all the
internal contents of a living cell
- separates the intracellular from the extracellular
cytoplasm- Answer consists of all the cellular contents inside the cell between the
plasma membrane and the nucleus
- Cytosol and Organelles
, Cytosol- Answer Fluid portion of cytoplasm
organelles- Answer A tiny cell structure that carries out a specific function within the
cell
- mitochondria
Smooth and rough endoplasmic reticulum
Golgi
Lysosomes
Nucleus - ANSWER - structure involved in gene expression and cell division
Genetic information storage
Plasma membrane functions - ANSWER - structural support
Physical isolations
Regulation of the exchange
Communication between cells and external environment
Structure of the Plasma Membrane - ANSWER - a phospholipid heads (sides) containing
lipid bilayer
The layer facing the exterior and interior of the cell are lipids
amphipathic molecules - Answer containing hydrophobic and hydrophilic regions
- both have polar and non polar parts
- hydrophilic ends face water fluid to avoid water spilling through the cell
Types Membrane Proteins - Answer integral proteins and peripheral proteins
