I am confused regarding the presence of valves in the superiorvena cava.

The superior vena cava does not possess valves unlike inferiorvena cava, which possesses Eustachian Valve.

Then where are Haversian valves present?

Aren't they present at the opening of caval i.e., superior venacava.

Then why is it said that there is absence of valves in superiorvena cava?

I need to answer questions ( very specifically ) 1. What did each of the bottles represent? What does the water represent? 2. What circulatory system structure do the check valves represent? What is their function in the circulatory system? 3. What do you predict would have happened if there were no valves present in the model? How would this affect the human body? Experiment 3: Modeling the Circulatory System In this experiment you will explore and model the structures and function of the circulatory system. Procedure 1. Use the permanent marker to label the plastic bottles 1 and 2. 2. Use a nail to carefully puncture two holes in the side of each bottle (approximately 3.5 cm from the bottom of the bottle) so that the holes are across from each other and at the same height from the bottom of the bottle. It is best to puncture the bottle with the nail straight through both sides. This will help keep the holes level. LAB SAFETY: BE EXTREMELY CAREFUL WHEN PUNCTURING THE BOTTLE. KEEP IN MIND WHERE YOUR HANDS ARE AT ALL TIMES. 3. You may need to maneuver the nail around the hole to make it large enough to fit the plastic tubing (Figure 7). The goal is for the tubing to fit tightly in the hole. 2 Check Valves 2 Drops of Dye Nail Permanent Marker 2 Plastic Bottles 60 cm of Tubing *Scissors *Water *You Must Provide Materials Figure 7: Maneuver the nail in a circular motion to enlarge the hole so that the tubing fits tightly. 386 The Circulatory and Respiratory Systems 4. Carefully cut the 60 cm tubing into four equal lengths of 15 cm. 5. Attach one end of one piece of 15 cm tubing to the OUT end of a check valve. 6. Attach one end of a second piece of tubing to the IN end of the check valve. 7. Repeat Steps 3 and 4 for the remaining check valve. 8. Construct a closed system by inserting the free ends of the tubes into the holes you created in the plastic bottles to create a loop. The tubes should be far enough into the bottle so that water can flow from tube to bottle to tube. The tubes in each bottle should not touch (Figure 8). Note: Properly assembled models should have the direction of the check valves facing in opposite directions. 9. Fill each bottle ¾ with water. The water level should be higher than the tubing. 10. Place the model on an underpad or paper towel to protect surfaces for the next step. This will also help catch water that leaks from the model. There should be minimal leaking if tubes are tightly in the bottles. 11. Place one drop of dye in each bottle and close the bottle by screwing on the caps. 12. Gently swirl the bottles to allow dye and water to mix. Be careful not to squeeze the bottles! 13. Note where the water is initially before squeezing the bottles and record your observations in Table 2. 14. Squeeze bottle 1 with both hands. Observe the direction of water flow and the water level in each bottle while you are squeezing and right after you stop squeezing. Record your observations in Table 2. 15. Repeat Step 13 for the bottle 2 and record your observations. 16. Squeeze one bottle and then the other back and forth.

Jeff (age 38) and John (Jeff's 18 year old son) are seeking theadvice of a genetic counselor after a family member was recentlydiagnosed with Huntington disease, a progressive and fatal nervoussystem disorder that manifests itself when individuals aregenerally between age 30 and age 50. If Jeff has inherited the genefor Huntington disease, then there is a 50% probability that he haspassed along the gene to Jason. Jeff shows no symptoms of thedisease and he prefers not to know whether or not he has the gene.However, John, who recently became engaged to his girlfriend wantsto know whether or not he possesses the gene for Huntingtondisease. If John is found to carry the gene, it means that Jeffalso has the gene. Jeff and John are very close, and John knowsthat he would be unable to conceal his test results from hisfather.

Discussion Questions:

1. Do you believe that John has a right to know whether or nothe carries the Huntington's disease gene despite Jeff's wishes toremain uninformed about his own status? Instead of just stating'yes' or 'no,' be sure to explain your answer.
2. Does Jeff have the right not to know his status?
3. Would you want to know or not know? Why or why not?
4. What are the signs/symptoms and complications of Huntington'sdisease?

As always, post a minimum of three times. Answer the questionsin your first posting and respond to your classmates in your otherpostings.

Related Information: The process of testing for suspectedgenetic defects before administering treatment is called geneticdiagnosis by genetic testing. In some cases in which a geneticdisease is present in an individual’s family, family members may beadvised to undergo genetic testing. For example, mutations in theBRCA genes may increase the likelihood of developing breast andovarian cancers in women and some other cancers in women and men. Awoman with breast cancer can be screened for these mutations. Ifone of the highrisk mutations is found, her female relatives mayalso wish to be screened for that particular mutation, or simply bemore vigilant for the occurrence of cancers. Genetic testing isalso offered for fetuses (or embryos with in vitro fertilization)to determine the presence or absence of disease-causing genes infamilies with specific debilitating diseases

Tasmanian devils (Sarcophilus harrisii), the world’s largest carnivorous marsupials, are facing extinction. Not from hunting, or habitat loss, but from within; a transmissible cancerous derivative of Schwann cells, responsible for devil facial tumour disease (DFTD). First seen in 1996, the disease has spread widely though the population, and is now estimated to be present in 80% of the population. With the grim prognosis of ~100% mortality in 12-18 months, animals that once went through multiple breeding cycles are now lucky to reproduce once before death, resulting in a 70% decline in their population over the past decade. The cancer is transmitted by biting (a common ritual used by these animals to establish and maintain social position), with cancer cells from one animal (the biter) being implanted in the wound inflicted on the other animal. Equally common in both sexes, the disease itself is more prevalent in animals higher on the social scale, presumably reflecting higher levels of social interaction (biting). The cancer is usually first evident as facial tumors, from which metastasis to cervical lymph nodes occurs, often followed by dissemination to other organ systems. Cause of death is by organ failure or by malnutrition in those with facial tumors large enough to prevent feeding. Based on what we have covered regarding the Major Histocompatibility Complex, you would expect the passage of a cancer from one individual to another* to be a rare event (to see just how rare, read the accompanying popular press piece from the New York Times). Here are some things that you already know: *Yes, some viruses can cause cancer (example: Hepatitis B virus and liver cancer), and you can transmit a virus from one individual to another; but that is not the same thing as passing the cancer itself. v Almost all nucleated cells express high levels of class I MHC proteins on their surface. v Class I MHC proteins collect peptides produced from endogenous proteins and display them at the cell surface. v Different Class I MHC proteins bind and display different peptides. v Developing cytotoxic T-cells that recognize self-antigens are eliminated. v Mature cytotoxic T-cells conduct surveillance by scanning the peptides displayed by class I MHC proteins. v Mature cytotoxic T-cells that recognize an antigen on a cell will kill that cell (recall that cytotoxic T cell activity is important in rejection of tissue transplants).

Before the questions:
v Tasmanian Devils are not immunosuppressed.
v Tasmanian Devil cytotoxic T-cells are not broken, they can kill cells.
So neither of those should be part of your answers.
This is an ongoing research topic with large gaps in our knowledge; we really don’t fully understand how this works
and so there is no “correct” answer. Your job is to provide a logical argument, with some research and details to
support your contention. Note that in questions 1 & 2 class I MHC should be part of your answer, but not in
question 3.

Questions:
1.) Acquiring DFTD is basically like receiving a transplant that is not rejected. How can that be? Suggest a possible
way this could occur. Be sure to explain why you think this would work, and then explain how you would test
that model to determine if it were correct. (10 point question).
2.) Canine Transmissible Venereal Tumor (CTVT) is the other know transmissible cancer in mammals. Unlike
DFTD, CTVT does not usually result in death. Do a little research on this disease and summarize how it is
different from DFTD. Provide an explanation as to why one is lethal and the other is generally not. (10 point
question).
3.) Recently, researchers at Washington State University determined that some Tasmanian devils had developed
resistance to this cancer. By scanning partial genome sequences of resistant and susceptible animals (a
complete devil genome has yet to be assembled) they identified a set of genes where mutations appeared to
enhance resistance. Speculate as to the function of the proteins these genes encode, and explain why that
might provide for resistance (note: they were NOT MHC genes).

Mainly need guidance/ideas for #1's 1 and 3!
