Jy het
lugweë wat bestaan uit neusgange, mondholte, keel (farinks), 'n
trachea (lugpyp) en twee
bronchi (longpype).
Jy het
twee longe bestaande uit duisende longsakkies/blasies of alveoli – die oppervlakte word dus vergroot tot so groot soos 'n pluimbalbaan!

Indien moontlik, moet jou onderwyser bogenoemde dele aan jou toon deur gebruik te maak van 'n skaap of vark se longe.
Die asemhalingsisteem van die mens
Prosesse
Behalwe voeding, is daar nog ander stelsels of sisteme in die mens wat belangrik is vir die doeltreffende funksionering van die liggaam. Ons gaan kyk na asemhaling, ekskresie, voortbeweging en die skelet, asook na voortplanting.
Elke sel in die liggaam van 'n lewende organisme moet suurstof hê vir
RESPIRASIE . Dit is die
ENERGIEGEWENDE PROSES waartydens glukose "verbrand" word in die teenwoordigheid van suurstof. Die afvalproduk is koolstofdioksied.
Die plek waar hierdie verbranding plaasvind binne-in selle, is die
MITOCHONDRIA .
Die manier waarop al hierdie stowwe by die selle in- en uitkom, is met behulp van die bloedstroom.
Die manier waarop suurstof in die bloed beland, is deur ASEMHALING en GASWISSELING.
ASEMHALING : die proses waardeur lug in die longe in en daaruit beweeg met behulp van spiere. Ons noem dit
INSPIRASIE (inaseming) en
EKSPIRASIE (uitaseming).
GASWISSELING : die proses waardeur gasse soos koolstofdioksied en suurstof in die longe tot in die bloed beweeg, asook by die selle.
RESPIRASIE : die energiegewende proses in mitochondria in selle.
Aanpassing vir die prosesse:
Vir
ASEMHALING is daar 'n
DIAFRAGMA of spierplaat onder die longe wat inbult en drukking in die borskas verander; daar is ook
TUSSENRIBSPIERE wat die ribbekas kan laat beweeg.
Vir
GASWISSELING is daar duisende longblasies of
ALVEOLI met baie dun bloedvatryke oppervlaktes wat klam is.
Vir
RESPIRASIE is daar fyn bloedkapillêre wat tot by elke sel strek met
WEEFSELVLOEISTOF wat elke sel omring; daar is ook vele mitochondria .

Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities.
before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these

continue..
sometimes due to these physical problems..the diagnosis may be misdiagnosed.
treatment for autism.
well it depends on the severity.
since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child
Jharna
child interact with other kids under doc supervision.
play therapy.
speech therapy.
Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game.
string and beads game.
the more you interact with the child the more effective
Jharna
results you'll get..
please consult a therapist to know what suits best on your child.
and last as a parent. I know sometimes it's overwhelming to guide a special kid.
but trust the process and be strong and patient as a parent.
