Instructions: Peer Responses 

125 Word Minimum

RESEARCH (Label this section)

• Teach the topic to students. Responses must add new      information not previously discussed. Consider new factual information      tied with critical thinking. Share interesting and current research on the      topic.
• Use APA citations in the post to clarify sources.
• Do not simply summarize another student’s post and      agree/disagree.
• Consider starting out posts with, “A research article I      found said,” “Did you know,” or “Three things I found      interesting were… .”

CRITICAL THINKING (Label this section)

• Pose new possibilities or opinions not previously      voiced.
• Connect the dots. Why is this an important topic for      you, your community, society, or the world? How does it relate to other      concepts in the text?
• Add references and word count for all posts.

1. Arteries vs. Capillaries      vs, Veins; Structure and Function

Research

  Arteries ate relatively strong, resilient structured tissue. Arteries are more muscular than veins, they hold their round shape even when they are empty. They appear circular or elliptical in sections of the tissue. Arteries are sometimes called the resistant vessels of the cardiovascular system that consist of three different classes by size. Conducting arteries distributing arteries and resistance arteries are the three different types. Conducting being the biggest resistance being the smallest and distributing binge the middle-sized arteries. The arteries are the vessels that carry blood away from the heart (Saladin, 2020, p.726).

Capillaries are sometimes called the exchange vessels of the cardiovascular system; they consist of endothelium and basal lamina. There are three types of capillaries. Continues capillaries, which occur is most tissues and organs. Fenestrated capillaries that are important in organs that engage in rapid absorption or filtration. Sinusoids are twisted tortuous passageways that conform to the shape of surrounding tissues. Some sinusoids contain microphages or other specialized cells (Saladin, 2020, p.729). Veins are thin walled and flaccid and expand easily. Veins are referred to as capacitance vessels. They accommodate the increase volume of blood and have a better containment of blood then arteries do. The blood flow in arteries is steady and collapse when they are empty. That Is why they have flat irregular shapes. Veins are defined as the afferent vessels that carry blood back to the heart. There are 5 kinds of veins working from the smallest to the largest: postcapillary venules, muscular venules, medium veins, venous sinuous, large veins.  The veins form from smallest to the larger veins as they get closer to the heart (Saladin, 2020, p.729-731).

Critical Thinking

  There are multiple kinds of each type of vessel, as always there is a lot more detail that complicates the structure of the human body. The analogy used in the book will make it easier for me to remember and recognize the different kinds of vessels in the body and what they do for the circulatory system.

What’s in Urine? Tell the story of making Pee: Functions  of each structure

Research 

The urinary  system functions to be able to  filter the blood and create urine as a waste.

The kidneys form the urine and account for the other functions , The ureters then carries    the urine away from  the kidneys to the urinary bladder, which is a temporary storage for the urine.

The nephrons of the kidneys process blood and create urine through a process of filtration.

There are 7 functions of the urinary  system: 

Removal of waste products and medicines from the body , balancing the body’s fluids , and balancing a variety of electrolytes , Release hormones to control blood pressure , Release a hormone to control red blood cell production, Help with bone health by controlling calcium and phosphorus.

Critical Thinking

What’s in our  pee ? and why  does it  change color so often ?

In our urine we have what’s called water urea. There is creatinine, ammonia, and pigmented products of blood breakdown, in the urine . We have  95% of water. The rest is urea  2% creatinine  0.1%  uric acid  0.03% chloride, sodium, potassium, sulphate, ammonium, phosphate. I  believe what  we put  in our  body  is what  comes out so  we should be careful of what  we put  in it  .

What  are the  colors  and why ? Clear mildly yellow urine means you are more hydrated , Means you  are drinking  lots of water I like to  say  , Dark amber urine is at the other end of the spectrum, This means the urine is more concentrated , either you  are not  drinking  enough  water , therefore you’re more dehydrated.

Certain foods and drinks can  change the color of our urine as well  even some medications , Which is  why  it’s very  important  to  talk with  our  doctors about  what  are side effects of our medications .
