Can you name at least 3 renctions ized allergie renctions and for systemic allergic reactions that cardinal signs and symptoms? 4(c)It is a little harder to find on p.795 and p.815 but part of the description for asthma also overlaps those and p not talking about of inflammation. What are those symptoms that overlap? (Hint: we are triction). 4(d)Prostaglandins are ofen released by cells during inflammatory responses in respesults in damaged (Ch. 20).

For example, in certain insects transmitting infectious disease agents such as the malaria parasite, w cycle infects human red blood cells. S(a)lt is mentioned in the blood chapter in the textbook what impact increase as part of its this malaria infection has on us.

Ground level ozone can also have an impact of your blood clotting interfering with the function of plasminogen (see p. 641, ed. 2). pyd If plasminogen can't be activated into plasmin, what is likely to happen in your blood vesselst 6(b)Ground level ozone and exposure to PM2.5s also have been associated with heart arrhythmias. If an individual suffers from cardiac arrhythmias at a significant enough level, clinical problems appear when arrhythmias reduce the pumping efficiency of the heart. If arrhythmias occur, what do you think could have in so-called sensitive populations such as those with a preexisting heart condition and the elderly? 7.GCC more and more have been implicated in being able to cause damage to the ozone layer in the stratosphere (upper layer of the atmosphere). With less ozone in the upper atmosphere, more UV light can make it to the planet surface.

This is called a 7(b)What can happen to the cell . and eventually to the tissue that the cell is part of? Can the change affect cell replication? 7(c)What happens if cell replication is affected so that cells replicate more? Explain your answer using some of the terms mentioned on pages 126 to 127 of your textbook. 7(d)Our bodies are not totally unprotected against the effects of this type of damage. What molecule found in your skin helps to prevent this DNA damage and what is it? Hint: This molecule increases in amount upon sun exposure, i.e. tanning. 7(e)How does this molecule (in its cell compartments) protect you from the UV damage? 8.On p. 758-59 ed. 2, the book discusses a certain type of immune cell that is directly involved in protecting us against damage that can arise from replication of "abnormal" cells. 8(a)Can you name the immune cell whose job it is to protect us? 8(b)The constant monitoring of normal tissues for cells that replicate abnormally fast is referred to as 8(c)These immune cells secrete which can kill the targeted abnormal cell. 8(d)If these abnormal cells avoid detection or secrete chemicals that kill the protective cells, these abnormal cells have undergone the process of and divide and spread to other body sites. and are free to grow

Explanation / Answer

5 a)

The organism responsible for malaria, Plasmodium has some of its life cycle stages associated with the red blood cells. As we know the main task of red blood cell is to carry oxygen. Thus the effect would be anemia. It is also characterized by fever due to the release of pyrogens in the blood system.

5 b) It may destroy both affected and unaffected cells further causing hemoglobinopathies.

5c)

Sickle cell anemia, a genetic disorder causes the RED BLOOD CELLs to be of sickle-shaped. This is deleterious for the survival of parasite and gives so some extent protection from malaria.
