Answer:
a. QRS
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
The QRS complex represents the time necessary for the impulse to travel through the bundle of His, the bundle branches, and the Purkinje fibers to complete ventricular activation or contraction, known as ventricular depolarization. QRS is simply a combination of the Q-wave, R-wave and the S-wave which represents electrical impulses.
A patient is admitted to the rehabilitation unit five days after having a stroke. the nurse assesses his muscle strength and determines that he has right-sided weakness. based on this assessment data, what part of the brain was injured?
There was damage to localized areas of the primary motor cortex in the left cerebral hemisphere.
1. Answer: What I learned from my Local Health department website is that if I were to help an area of need I should start by picking up any trash and litter, I should also help recycling to help the environment. I also learned that I should recreate the area by seeing if it needs extra biking trails or exercise trails, I should also see if there needs to be any walking paths so people can walk, I should also add little riddles on signs and spread them throughout the area so they could also do a little bit of walking. There is also smoking problems so I think that putting a sign that ban's smoking in that area. I feel like the area should also check to see if anybody is sick so they wont get anybody else infected and keep the area clean and healthy.
2. Answer: I learned that we should care for ourselves and the things around us to have a better environment and a healthier life. If we don't do so the world won't be healthy and neither will we be.
3. Answer: The plan I came up with to help with health and safety is to make sure that we have a stand where we check to see if anybody is sick, the safety is where if kids don't have knee pads or anything to protect themselves we have another stand where we sell all of that only for a dollar, we also have a first aid kit. The reason why I chose to address the issue is because I want to make the world a better place no matter what. Me and my family would love to help out to see the children smiling in a clean environment. I will try my best with all I got and pick up trash, recycle, and help as much as possible. Maybe when I'm old enough so I can be mature and the place would most likely be a park or just a random area and turn it into something nice.
4. Answer: How I plan to monitor and measure my progress is a before and after picture! How I put up smaller tasks to accomplish, schedules, deadlines, and manage time is just by playing little mini games that have a timer so we can have fun and get more done.
