CRITICAL THINKING (Label this section)
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).
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
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.
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 .
