Elephantiasis?!
Are you infected with Elephantiasis?
You actually might not know because the infection is acquired in childhood but manifests later in life.
Elephantiasis actually infects more than 1.4 billion people in 73 countries. This disease is caused by infection with nematodes. Infection happens when parasites are transmitted to humans through mosquitos. When a mosquito has is infected with larvae and bites a person, the parasites become disposited on the skin, where they can enter the body. The larvae migrates to the lymphatic vessels where they develop in the lymphatic system into adult worms. Once the grow into an adult size, worms enter the lymphatic system and interrupts the processes that occur in the immune system. They can live in their for 6-8 years! EEEWWWW!
The symptoms are inflammation of the skin, lymph nodes and lymphatic vessels. When it the disease develops into chronic conditions, limbs have an increase in fluid accumulation. Most body parts are affected. As a result, the body grows larger in size.
The treatment is medication that can clear microfilarie from the bloodstream. Using mosquito nets and mosquito spray can help prevent mosquito bites and prevent infection. Those are who infected with the disease are required to keep and maintain hygiene and take further precautions.
Tip: Mosquitos also cause other diseases so prevent yourself from becoming infected!

Questions: Spirometer
1. My vital capacity is 3.15 liters. My vital capacity is above the average for females. My vital capacity is in the middle of all the ranges in the class because the lowest is 1.6 liters and the highest is 5 liters. I think my vital capacity is what it is because I have been dancing since I was three and I believe cardiovascular activites and running has also helped. I believe the lowest capacities are what they are because those people might not play instruments or exercise. I believe the higher vital capacities are what they are because those people are probably extremely physically active or plays instruments.
2. In a usual breathe there is about 500mL. Males can exhale 4L and females can exhale 2L. Our breaths are the way they are because females have a smaller build than males and therefore have smaller lungs. I also feel a females diaphragm is smaller causing her to inhale/exhale less air.
3. The mechanism of exhaling forcefully differs from the usual exhalation because when we are breathing it is automatic and we do not think about it. We also just expand our diaphragm a little/as much as our body currently needs. We control exhaling forcefully and we push our lungs to hold more air. We make our muscles expand to release air voluntarily.
Practicing at this via exercise/instrument playing/singing makes you better at it because you are making your lungs work harder and as a result they become stronger and have the capability of holding more air. We also take large and longer breaths while doing these activities which help strengthen our breathing abilities.

Questions: Inhale - Exhale
Inspiration is
the process in which the intercostals muscles receive multiple nerve pulses,
which cause them to contract. When the muscles contract the diaphragm does too.
When the volume in the thoracic cavity increases, the elastic lungs stretch out
because they are connected to the walls of the cavity, by a membrane called
pleura. The lungs expand and the thorax expands. The lungs increase in volume
and the expansion lowers the air pressure. The air molecules move from high to
low pressure.
Expiration is
when intercostals muscles and the diaphragm relax. The lungs are able to return
to its original dome shape. During the process of relaxation, the volume of the
thoracic cavity deceases. This causes the lungs to compress so they return to
their original size. The air within the lungs is compressed and the exhaled air
then flows out.
Inflation of the
lungs are caused by the contractions of the thoracic cavity which increase the
size of the lungs. The lungs expand and increase the volume of space within
them.
Deflation of the
lungs are caused by the relaxation of the intercostals muscles and diaphragm.
When the volume of the thoracic cavity decreases the lungs compress/deflate.
Part of the
process requires a muscle contraction of the diaphragm is inhalation.
