Blood flows throughout the body in order to supple the organs with nutrients and oxygen. In order for that to happen the blood has to be pumped. The heart does the pumping of the blood to ensure the organs receive the blood. Blood enters the heart through the superior vena cava and the inferior vena cava. From the vena cava the blood flows into the right atrium. There is a right atrioventricular valve that is between the right atrium and the right ventricle to prevent the blood from flowing into the ventricle. When there is enough pressure in the right atricum the right atrioventricular valve opens and the blood rushes into the right atrium. In order from the blood to get oxygenated the blood then leaves the right ventricle by the pulmonary semilunar valve which directs the blood to the pulmonary trunk. The pulmonary trunk leads the blood to the lungs where the blood is oxygenated. From the lungs the blood enters the right and left pulmonary veins into the left atrium. There is a left atrioventricular valve that prevents the blood in the atrium from flowing into the ventricle. When there is enough pressure built up by the blood in the left atrium the left atrioventricular valve opens and blood flows into the left ventricle. From the left ventricle the blood flows through the aortic semilunar valve and into the ascending aorta. From the aorta the blood goes to all parts of the body.

Scientists tackle the question whether probiotics are worth taking. The answer is that it depends on the situation of the person. If someone is healthy and are taking probiotics, there is actually no point in taking the probiotics. The probiotics ingested would not compared to the number of microbes in the gut. The ingested probiotic would just be kicked out of the system in general. As compared to a person that is taking an antibiotic that is going to wipe out the person’s microbes, the good and the bad. Consuming probiotics would allow good microbes to settle in the person’s body. Thus, allowing a defense mechanism against other microbes and bacteria. So it really depends on who is consuming the probiotics. When a healthy person consumes it the probiotics are just going to waste. While others who have a weakened immune system would find benefits of consuming probiotics.  Probiotics were marketed because of people trying to profit off others for staying “healthy”. 

I woke up at 6 in the morning. I brushed my teeth and changed into some warm clothes. I went to work making coffee for people for three hours. I got grab and go which consisted of a bacon egg and cheese english muffin and a yogurt. Then I went to class for an hour. After class I went back to work and made more coffee for another hour. I had lunch for half an hour with a friend. After lunch I walked to my writing class which lasts for two hours and twenty minutes. 

I don’t know how many of you kept the larvae from last week but I did. When I took the larvae back to my dorm room I found out that the larvae feed off of decaying vegetation. I put an orange peeling into the cup to see what would happen. A day later the larvae started to move slower around the perimeter of the cup and eventually stayed in one spot. I thought that I had killed the larvae due to the acidity in the orange peel, but the larvae was just moving in a slower rate. Two days after the larvae turned into a cocoon. The cocoon is a dark brown color similar to that of a coffee bean. The cocoon is smaller in size from the initial larvae stage, around 5 segments in length. It has been four days since the larvae turned into a cocoon. 

The article from Neuroscience News (https://neurosciencenews.com/sleep-pain-10648/) explained the consequences of not having enough sleep and how that affects pain sensitivity. Researches were attempting to find out if sleep was necessary for a full recovery. Their main focus was on how to make the hospital a better place for people to recover better. The study that was conducted was a behavioral intervention. The researches put heating pads on the participants lower legs and measured their brain activity with an fMRI. The somatosensory cortex, which is the part of the brain where pain signals were received showed a 126% increase when the participant did not get a full nights rest. My question is that the knowledge is used to discharge patients back to their homes to allow for fuller nights rest due to the fact that the hospitals are too loud to induce sleep. If that is the case would it still take just as long for the patient to get well enough to be discharged from the hospital?

The worm is approximately half an inch in length and is made up of 10 segments. One end of the worm is smaller than the other end, similar to that of a cone. The end that is smaller has a darkened tip which appears to be the head. On the larger end there are two dark end spots. The two dark spots are dorsally placed when the worm is moving. The skin of the worm is transparent, which makes it possible to see inside. Inside the worm is a white fluid that moves when the worm moves. The worm moves by inching forward starting with the head, first by lifting it up and the rest of the body follows, similar to a wave. When the container was shaken the worm shrinks into itself and stays still for a few minutes. After, the worm just resumes squirming around the perimeter of the container. The worm takes 1 minute to travel the perimeter of the container. There are side bumps that may assist with movement, when it doesn't have a perimeter for it to follow, the worm rolls when it moves. The worm just moves forward in one direction. The way the worm moves just changes its direction, it doesn’t appear to be intentional. When the container is flipped upside down and then back up, the worm was able to stick to the surface for a few seconds before falling.
