Do you think that the symmetry test conducted on the baby was flawed? How? Describe how you would design an experiment that could fool the baby and skew the results. I mean a baby is going to look at the most colorfulness thing that they see and the prettiest thing that they see. I would put a whole lot of colors on an ugly person and put all black on a beautiful person and see who the baby looks at.
What is missing from this video about beauty? That all people look different and are pretty in their own little way.
What are features that might break the “typical” beauty rules? How are these different from the “typical” beauty rules? Features like deformity and scars, I guess that the “typical” rule is that you can’t have any scars.
How does this video make you feel about beauty? Really it doesn’t make me feel any different because I have my own beliefs and thoughts on beauty, everyone is beautiful in their own little way.
What is it about the skin that makes it return to its place? What property is this? After it is stretched its like a rubber band.
What are the risks of cosmetic surgery? Would you ever do it? What would you be willing to risk for cosmetic surgery? How long will it last? The risk could be that everything could go all wrong and you could wake up during the surgery and it would just be crazy. No I wouldn’t do it, and it wouldn’t last because I wouldn’t do it.
Someone in the video is quoted as saying that “make-up can make anyone prettier.” Do you agree with this? Support your answer. Nope, because I fell that everyone is pretty with or without make-up. Make-up doesn’t make or break a person because beauty is only skin deep. Its what’s on the inside that counts.
Do you think that there are cultural differences in how cosmetic surgery is viewed? YES IT IS!!!!!

The stem cell research is bout detecting different types of disease in humans and finding out ways to cure them. I think that this is a good idea because that might be me one day in that situation and I might have Alzheimer’s and I might need to be cured. Hopefully by then they would have been found something where they might be able to find it early or cure it. This could be helpful in so many ways and it could stop a lot of things that has happened and prevent things that would have happened if they didn’t have this system. I hope that in the future they do find ways to cure this and maybe I might decide to major in it.

basic anatomy system worksheet
1. What does CNS and PNS stand for? CNS stands for the Central Nervous System, and PNS stands for Peripheral Nervous System.
2. What are the parts of the CNS? It consists of the spinal cord, and the brain. It controls the thinking the memory and the behavior.
3. Describe something that you do on a regular basis that your PNS controls. It sends messages and nerve sensory to the rest of my body.
4. What are the two divisions of the autonomic nervous system and what does each control? It is divided into the Sympathetic and the Parasympathetic Nervous system. The sympathetic branch controls the body in time of stress and worry, fear, and emergency. The parasympathetic branch brings the body back to a normal state and allows the rest and relaxation to occur.
5. What are the three main types of neurons? What is the function of each? Sensory Neuron, Motor Neuron, Interneuron. Sensory neurons help to sent the message to the motor neuron and the motor neuron helps to send the sense to the interneuron and that’s where it is then sent to the brain.
6. What is the function of the axon of a nerve cell? The dendrite? The axon is the sending end of the neuron, and the dendrite is the receiving end of the neuron.

Blood Tales
the chambers of the heart the blood enters
the chambers of the heart the blood exits
when the blood goes to the lungs
what the blood carries between the lungs and the body
name the main veins and arteries the blood travels
name the main element contained in red blood cells
Today as i took a stroll down the street i saw something that might have been cool. It was the circulartory and respiratory system. So me being th type of person i am i decided to take a little field trip and explore what stood before me. As i jumped on a bllod platelet that i found in streaming on top of some blood i found in the surperior and inferior vena cavae, it started to take me on a ride. It took me on through these pretyty colorful tubes that i found out are called the atria which also goes through the ventricles and the arteries. As i thought i came closer to the exit because thats where it leads to i ended up going to the pulmonary artery that also has something to do with the lungs. From there we took a left turn and went into the artia, then after that we went to the aorta which we had to go through the body to get too. From there we went to the Vena cavae and that was the end and thats when i hopped off and there someone was to greet me. He explained to me the tour i had taken and explained t starts all over.

Circulatory and respiratory system questions in text
Critical Thinking
6) If a woman whose blood is Rh-negative and contains anti-Rh antibodies is carrying a fetus with Rh-negative blood, will the fetus be in danger of developing erythroblastosis fetails? Why or why not?
Answer: Yes, because these antibodies called hemolysins, cross the placental membrane and destroy the fetal red blood cells.
Review Exercises:
3) Describe a red blood cell.
Answer: They are biconcave disks which mean that they are thin near the centers and thicker around their rims. This special shape is an adaption for the red blood cells function of transporting gases.
6) Describe the life cycle of a red blood cell.
Answer: Red blood cell formation initially occurs in the yolk sac, liver, and spleen. After an infant is born, these cells are produced almost exclusively by tissue lining the spaces in bones, filled with red blood marrow.
10) List two sources of iron that can be used for the synthesis of hemoglobin.
Answer: An iron protein complex called ferritin, and the biliverdin is converted into and orange pigment called bilirubin.
14) Describe a blood platelet, and explain its functions.
Answer: Platelets or other known as thrombocytes, are not complete cells. They arise from very large cells in the red blood marrow, called megakyrocytes, that fragment a little like a shattered plate, releasing small sections of cytoplasm platelets into the circulation. Platelets help to repair damaged blood vessels by sticking to broken surfaces.
18) Distinguish between low-density lipoprotein and high density lipoprotein.
Answer: Low density lipoproteins have a relatively high concentration of cholesterol and are the major cholesterol-carrying lipoproteins. High-density lipoproteins have a relatively high concentration of protein and a lower concentration of lipids.
27) List the major steps leading the formation of a blood clot.
Answer: Platelets stick to each other forming a platelet plug in the vascular break.
Break in the vessel wall, blood escaping through the break; platelets adhere to each other, to the end of the broken vessel, and exposed collagen, platelet plug helps control blood loss.
38) Explain why a person with blood type AB is sometime called a universal donor recipient?
Answer: Because they can receive a blood transfusion of any other type of blood.
39) Explain why a person with the blood type O is sometimes called a universal donor?
Answer: Because it contains both anti-A and anti-B.
Pages 647 and 648 Review Exercises: 2, 4, 6, 10, 19, and 36
2) Describe the Pericardium.
Answer: it is the closing that encloses the heart and the proximal ends of the large blood vessels to which it attaches.
4) Identify and describe the locations of the chambers and the valves of the heart.
Answers: The heart is bordered laterally by the lungs, posteriorly by the spinal cord and anteriorly by the sternum. Its base, which is attached to several large blood vessels, lies beneath the second rib. Its distal end extends downward and to the left, terminating as bluntly pointed apex at the level of the fifth intercoastal space. It is divided into the pericardium, epicardium, myocardium, and endocardium.
6) Trace the path of blood through the heart
Answer: It goes from The blood from the systemic circuit into the vena cavae, to the right atrium, right ventricle pulmonary trunk, pulmonary arteries, alveolar capillaries,, pulmonary veins, left atrium, left ventricle, aorta, and the blood to systemic circuit.
10) Explain the origin of the heart sounds.
Answer: The sounds of the heart whenever the vibrations in the tissue are sped up or slowed down when the heart chambers contract or relax and when the valves open or close.
19) Describe the structure and function of a capillary.
Answer: Capillaries are the smallest diameter blood vessels. It also connects the arterioles and the smallest venules.
36) Describe the relationship between the major venous pathways and the major arterial pathways.
Answer:

1) Describe the general functions of the respiratory system.
The movement of air in and out of your body, the exchange of gases between the air, the transport of gases, and oxygen utilization and production of carbon dioxide.
3) Explain how the nose and nasal cavity filter incoming air.
Heat radiates from the blood to warm the air, and the mucous lining controls the air.
5) Distinguish between the pharynx and the larynx.
The pharynx is at the back of the oral cavity and between the nasal cavity and the larynx is at the superior of the trachea and the inferior of the pharynx.
9) List the successive branches of the bronchial tree, from the primary bronchi to the alveoli.
Secondary bronchus, bronchi, right and left primary bronchi, segmental bronchi, interlobular bronchioles, terminal bronchioles, respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli.
16) Define surfactant, and explain its function.
A substance the lungs produce that reduces the surface of the tension within the alveoli.
22) Compare the mechanism of coughing and sneezing and explain the difference of each.
A sneeze clears the upper respiratory system, and a cough clears the lower ones.
23) Explain the function of yawing.
The low blood oxygen concentration somehow triggers the yawn reflex, prompting a very deep breath that ventilates alveoli.
31) Define hyperventilation, and explain how it affects the respiratory system.
Hyperventilation- is where it lowers the blood carbon dioxide concentration below normal. In a person this causes in irregular breathing.
35) Describe how oxygen is transported in blood.
As oxygen dissolves into the blood it rapidly combines with hemoglobin forming new oxygen called oxyhemoglobin.
36) List three factors that increase release of oxygen from the blood.
6) If a woman whose blood is Rh-negative and contains anti-Rh antibodies is carrying a fetus with Rh-negative blood, will the fetus be in danger of developing erythroblastosis fetails? Why or why not?
Answer: Yes, because these antibodies called hemolysins, cross the placental membrane and destroy the fetal red blood cells.
