Quiz 5 - Cell Organization: Tissues and Organs (lectures) Flashcards
What anchors cells together? what connects them?
cytoskeleton
cytoskeleton
joins cells together
T/F: Most cells are connected to other cells
T
cells form together to make __ and__
tissues and organs
4 types of tissues
- epithelial
- connective
- muscle
- nervous
function of epitheleal cells
deal with one set of cells that aren’t you
function of connective tissues
- hold things together
T/F all connective tissues fall in the same category
F
function of muscle tissue
- allows the body to do work
- causes cytoskeleton and muscle contraction
function of the nervous tissue
- allows for rapid communication throughout the body
example of epithelial tissue
- skin
- lung tissue
- ## digestive tract
T/F stem cells can form into different types of cells
T
T/F stem cells are found in only one place
F: stem cells are found throughout the body
exampes of connective tissues
- tendons
- ligaments
- cartilage
- fat
- blood
- bone
T/F: bones are alive
T
T/F: there are both bone making and bone eating cells
T
What are voluntary movements of muscle tissue?
you decide the movements
what are involuntary movements within the body?
- automatic movements
- you don’t have to think about them for them to happen
cardiac muscle: voluntary or involuntary?
involuntary
example of a cardiac muscle
- heart muscle
example of involuntary muscle movement
- eating
- breathing
T/F: muscles work/fire on their own
F: they are initiated by an electrical signal which comes from your nerves through communication with your brain
main function of nerves:
- send electrical signals
nervous tissue
- allows for rapid voluntary and involuntary communication through electrical signals
- example of problems with nerves: multiple sclorosis
- problem with cells that provide insulation and protection
what causes the muscles to contract?
nerves
types of organ systems (11)
- digestive
- respiratory
- circulatory
- immune/lymphatic
- excretory
- endocrine
- nervous
- integumentary
- skeletal
- muscular
- reproductive
digestive systems
- secrete things
- release chemicals to break food down
- absorb what is broken down
What drives the circulatory system?
the blood which is moved by the heart
function of excretory system
- waste removal
function of endocrine system
- produce hormones
- deals with organs and cells that deal with hormone production
hormones
- cells produced in one place of your body (ex: thyroid)
- travel through the blood to reach another location in the body
nervous system
- fires signals allowing communication
function of integumentary system
- deals with what is on the outside of you (hair nails skin)
function of reproduction
- producing gametes
- meiosis
