The SA Node is the heart's normal pacemaker. When the SA Node depolarizes, electrical signal spreads through the atrial muscle causing contraction.
Explanation:
Inherent rhythmicity / automaticity - The property of the pacemaker cells of the heart to start electrical sequence of depolarization and repolarization.
SA Node or Sino-atrial Node generates the electrical signal.
The electrical signal passes through internodal pathways, atrial fibres, atrioventricular node (AV Node), the bundle of His, Purkinje fibres, right bundle branch, left bundle branch.
Systole - Contraction of cells when the electrical signal of depolarization reaches the contractile cells.
Diastole - Relaxation of cells when the electrical signal of repolarization reaches the myocardial cells.
Answer:
One thing most parents can agree on is that parenting is challenging, whether you are a parent of a baby, toddler, or teenager. One day you may feel as if you've figured it all out and then the next you feel like the worst parent in the world.Many parents spend too much time searching for ways to change their child's behavior. This method of parenting often backfires and parents are perplexed when they are left with crying babies, toddlers having major meltdowns, and disrespectful teenagers.
Think about something your child does that makes you lose your cool. We are all triggered by different things. Is it when your toddler raises her voice in public? Or is it when 10-year-old refuses to clean his room? Think about why the behavior bothers you. Are you embarrassed in front of others?
Was this behavior unacceptable when you were a child?
Many of these behaviors are frustrating, but they are also developmentally appropriate. Think about what your child may be getting out of this behavior you consider “bad." A negative reaction from a parent is good enough for a kid who is trying to get any attention, but it will only keeping the behavior going. The less you stress about the behavior, the sooner it will come to an end. Sometimes the power struggle is the reason the behavior continues.
Explanation:
What if we stopped trying to change our kids and, instead, changed how we thought about parenting? What if we chose to view parenting through rose-colored glasses? What if we decided not to take everything so seriously?
Answer: The squamous epithelial layer of tissues forms an important layer that lines the organs in the human or animal body.
Explanation:
The squamous epithelium ensures the absorption or transport of the materials, diffusion, filtration, and osmosis. It forms the part of the walls of the capillaries and that of alveoli of the lungs. If the squamous epithelium fails to function then capillaries may disintegrate, lung alveoli may rupture, and chances of organ failure will increase.
Smoking or drug addiction for an expecting mother is more dangerous because not only are the chemicals affecting her but they are affecting her baby as well if addiction continues through to the birth of the child the baby can experience withdrawal symptoms and can be underdeveloped
