Homeostasis, CH 1

Question 1

Pathophysiology

Answer 1

is an abnormal function on the body that causes disease

Question 2

How many body systems, name them

Answer 2

11: Circulatory, integumentary, digestive, respiratory, urinary, skeletal, muscular, immune, nervous. endocrine, reproductive

Question 3

Levels of organization in the Body

Answer 3

Chemical, cellular, tissues, organs, organ systems, organism

Question 4

Four tissue types

Answer 4

CMEN: Connective, Muscular, Epithelial, Nervous

Question 5

Connective tissue types and function

Answer 5

Loose (Areolar), Dense (regular and irregular), adipose, bone, blood, cartilage. Connects supports and anchors body parts

Question 6

What type of tissues are blood and lymph

Answer 6

Fluid Connective

Question 7

Name the types of muscular tissue and function

Answer 7

Smooth- movement of contents through tubes and organs, Cardiac contracts heart to pump blood, skeletal moves the skeleton

Question 8

Name the types of nervous tissue and function

Answer 8

Central and Peripheral nervous systems. Send signals via action potential. Found in brain, spinal cord,nerve, and sense organs

Question 9

Name epithelial tissues

Answer 9

Simple, stratified, pseudostratified

Question 10

Simple

Answer 10

Squamous, cuboidal, columnar

Question 11

stratified

Answer 11

Squamous, cuboidal, columnar

Question 12

pseudostratified types and location

Answer 12

Transitional (bladder), Columnar (trachea)

Question 13

what is PSCCE

Answer 13

pseudostratified ciliated columnar epithelial

Question 14

what type of tissue is used for secretion

Answer 14

epithelial specifically glands

Question 15

the two types of glands

Answer 15

exocrine and endocrine

Question 16

Define endocrine

Answer 16

Secretions are released inside the body into the blood in the from of hormones

Question 17

define exocrine

Answer 17

exocrine glands release secretions outside the body or into a cavity in the from of sweat and digestive juices

Question 18

Define homeostasis

Answer 18

maintenance of a stable internal environment

Question 19

Two types of fluid that are components of cellular homeostasis

Answer 19

ICF and ECF

Question 20

Two components of ECF

Answer 20

Plasma and Interstitial fluid

Question 21

Lymph is an example of ECF true or false

Answer 21

True

Question 22

Components of Homeostasis

Answer 22

concentration of: nutrients, O2, CO2, waste products, electrolytes, water; pH, volume, pressure, temp

Question 23

two homeostatic control systems

Answer 23

Intrinsic and Extrinsic

Question 24

Define Intrinsic and give an example

Answer 24

Intrinsic acts within and organ ie. Muscle tissue releasing chemicals that act on attached blood vessels to cause them to dialate when O2 drops

Question 25

Define extrinsic and give an example

Answer 25

Extrinsic means that regulatory mechanisms that are outside the organ control the organs activity. When blood pressure drops the brain sends signals to the heart and blood vessels to increase heart rate and constrict vessels to bring up BP

Question 26

Most common type of feedback to maintain homeostasis

Answer 26

Negative feedback loop

Question 27

What are the stages of a negative feedback loop

Answer 27

Receptor gets the message (change from baseline), sends the message to the control center (usually the brain), sends the message to the effector, which produces a compensentory response to bring the variable to normal baseline.

Question 28

What is a positive feedback loop

Answer 28

It amplifies the initial change and continues to move further away from the set point.

Question 29

What are examples of positive feedback

Answer 29

oxytocin in childbirth and breastfeeding, and action potentials in cell membrane
