Any Ideas on How to Make/Build a 3-d Model on the Cardiovascular System?

Get 2 small balloons and two slightly larger ones. Get 4 one way valves (from party toys or otherwise) and some tape and some tubing. small, large, (tubing loop), small, large, bigger loop. Red food colouring in the water. tape all 4 balloons together. Then you can squeeze the top, then the bottom and watch the system flow. (you will need some air in the proto system that is not there in real life, but it should still work great)

1. what are the organs in a cardiovascular system?

As "norton" said, the only organ of the CV system is the heart. The accessory structures are arteries, veins, arterioles, venules and capillaries

2. What are five assumptions made when modeling the human cardiovascular system?

The modeling describes the transportation of various substances such as oxygen or anesthetic agents in the human body. In order to develop such a model one must think of a generic human body in two distinct ways: As an average human being and as a simplified and idealized object. One simplification is that blood is a homogeneous fluid. Another is that various body tissues can be grouped together into a few compartments, e.g. in the respiratory model, the complex branching of the airways are lumped into four compartments depending on the diameter of the airways. In this way we think of the human body not as it is in reality, but as an idealized and simplified object. All measurements and mathematical models use such idealized versions of real objects. It is important to notice that physical measurements always must be interpreted based on a set of assumptions that makes sense relative to the model object. For example, when an invasive blood pressure is measured in a large artery it is assumed that the catheter is placed in a smooth laminar blood stream and that the blood is a well-behaving incompressible fluid. Impurities and interfering features are eliminated or included in a negligible amount of noise. Furthermore, fundamental laws of nature only hold for generic model objects and not for objects as they are in themselves. Consider, for instance, the incompressible Navier-Stokes equations. They can be derived from the Boltzmann equation of non-equilibrium statistical mechanics under some simplifying assumptions: that the flow field varies only in length and time scales much greater than the microscopic scales associated with the mean free path and mean free time of particles, and that velocities are much less than the speed of sound. Therefore, when we apply Navier-Stokes equations we tacitly assume that our fluid is a system of particles complying with such general assumptions. Consequently, when we embark on the task of building a mathematical model of a physiological process in accordance with fundamental laws, we have already made far-reaching generalizations. We are considering a generic human being as a model object. However, in order to construct a mathematical model which is computationally accessible we must make even more radical idealizations and simplifications. As an example, consider the arterial tree. When a clinician is measuring the blood pressure somewhere in a large artery it is assumed that there is a definite well-defined pressure at that place, e.g. that the blood flow is regular and smooth enough to allow a well-defined pressure. But when we want to construct a mathematical model of the arterial tree which can predict pressure and flow profiles we must make a series of simplifications. First, we must make the assumptions underlying the Navier-Stokes equations. Second, we must simplify the arterial tree such that we have a manageable number of equations. Finally, the equations must be simplified so they are accessible to numerical solution.

3. Why is the cardiovascular system important for overall health?

The cardiovascular system is a circulatory structure composed of the heart, each layer of arteries, a huge network of capillaries, and layers of veins. Our blood will eject from the left ventricle, pass through the aorta, aorta, middle artery, and small arteries, and finally reach the capillaries that only allow the smallest cells of the human body to pass through. It is only one tenth the thin of a hair. The capillaries bring oxygen and nutrients to the 37. 2 trillion cells of the body without falling to the ground, and then recover them from the capillaries to the small veins, middle veins, and central veins, and finally return to the right atrium and flow to the right ventricle. As the heart contracts, the blood ejected from the right ventricle passes through the arteries, capillaries, and veins of the lungs to bring oxygen back to the left atrium and flow to the left ventricle. If you add up the blood vessels of the whole body, from arteries to veins, it is 176,000 kilometers, and it goes around the earth's equator about 4 and a half times. The blood vessels of our body are like a road system extending in all directions. The roads carry the responsibility and burden of transporting oxygen and nutrients day after day. The damage to the road is like the accumulation of blood vessel problems. Once blocked, "traffic accidents" are prone to occur. The well-known coronary heart disease, myocardial infarction, cerebral stroke, lower extremity artery occlusion. Myocardial infarctions and strokes that make us feel so anxious are actually chronic diseases of the cardiovascular system (natural damage). Therefore, different blood vessel blockages cause different diseases:Cerebral vascular blockage: Stroke After a stroke, hemiplegia, slurred speech, loss of mobility, and bedridden may occur.Cardiovascular blockage: Myocardial infarction If the degree of blockage is mild, it may only be affected by the heart's pumping ability; and severe myocardial infarction may be fatal at any time.Blockage of blood vessels in the legs: arteriosclerosis, venous thrombosis. Severe blockage of the arteries may lead to avascular necrosis of the legs and feet, even requiring amputation. If venous thrombosis falls off and enters the pulmonary blood vessels, it may cause pulmonary embolism.Pulmonary embolism: Pulmonary embolism is usually acute. When the blood vessels are blocked too much, people may suffocate and die.If someone unfortunately has a myocardial infarction at the age of fifty, then the first "plaque" has begun to grow on the wall of his blood vessel in his twenties. This "plaque" will continue to grow in the future until it blocks blood vessels and myocardial infarction breaks out. Why is it important to have a healthy cardiovascular system?

What Are Some Ways to Keep My Hair Really Healthy?
Use professional shampoo & conditioner. I know it may seem like a rip-off, however all the shampoos like Pantene, Garnier, etc. have a high alcohol content....since the normal pH of your hair is 4.5-5.5, things containing high amounts of alcohol throw your hair all out of whack and cause breakage, split-ends, fly-aways, etc. The reason these shampoos make your hair feel soft is because they contain high amounts of humectants, which are just a cover for how damaging they really are! Another tip is ALWAYS use a thermal protector while applying heat. Heat appliances cause tons of damage to your hair. Usually this is a cream/clear gel you apply before blow drying. Never use a flat iron on hair that is not completely dry!1. Split End Help. ( 10 Points) !!!!!!!!!!!!!!!!!!!!!!?For sure you should get a trim and maybe even cut your hair as short as you are comfortable doing it. You should for no reason straighten or dye your hair. Look for some Garnier Fructis or Pantene shampoos and conditioner for curly hair so that it extra moisturizes it and helps the split ends repair themselves. I say from experience that ppl with curly hair have really bad split ends, which is why we have special stuff in our hair products. The split ends wont magically go away in like a month or a few weeks, but you will see improvement after a while. Oh, and for sure DO NOT PICK THEM OFF!! It will just make it worse. Every two months until your hair is healthy get a trim. just maybe half an inch or an inch will be just fine. Eventually your hair will go back to normal. Good luck with that!.2. Whats the best shampoo conditioner for cheap?clever or V05 are solid inexpensive ($a million) shampoos, yet whilst it is composed of conditioner i could bypass Tresemme ($6) it does an somewhat solid interest. i take advantage of salon shampoo because of the fact i am form of a hair snob, yet I nonetheless use the cheap conditioner. Pantene is undesirable on your hair (too plenty protein and reasons alot of greater build up on the hair) so i does not bypass there. desire this permits! My hair is oily, superb, and colour-taken care of if that helps you any!3. How can I get my curly hair to be nice like Taylor Swift?Haha i have the same hair long and curly..but not pretty curly! im completely obsessed with taylor and her hair so i did so playing with it and what you really NEED to get is the conair hot sticks!! they are these little flexible curlers and they are not very expensive and i would look like a frizz ball without them!! you can like get them at walmart. anyways what i do when iwear my hair curly is like i get up and get in the shower and wash it and condition it and this may sound weird but dont use a whole lot of conditioner just enough to get it done cause it will help your hair hold the curl the just get out and towel dry your hair till it is just damp and then put a curling mouse in it and frizz serum then finish blow drying it straight! and you know have the curlers on like when your gettin in the shower and then just make sure the little light is on meaning that they are hot enough and then seperate your hair into pretty small peices (if you have really thick hair then you might need to buy two sets cause they only have 14 in them and you use small sections) and then start from the botom of your hair and role it through your hair and pin it together youll see the instructions on how to pin them together and make sure you wrap it all the way to the top of your head and leave them for like 15 or 20 minutes while your finishin gettin ready and then use like a light hairspray about 5 minutes before you take them out then your done. i know this thing was really long but its not that hard lol!!!! hope i helped good luck!!!!!!!!
