Did you know…..
Atherosclerosis is the hardening of the coronary arteries
Thrombosis is the blood clotting in the arteries that blocks the blood flow.
Angina is the discomfort in your chest or chest pain caused by the poor blood flow through the coronary arteries to the myocardium.
Coronary heart diseases which is caused by the building of plaque in the arteries an this can lead to a HEART ATTACK
After that class are SUPER DUPER AWESOME Teacher Mr. Morrison had us listen to this awesome song!

The heart is made up of four different blood-filled areas, and each of these areas is called a chamber. There are two chambers on each side of the heart. One chamber is on the top and one chamber is on the bottom. The two chambers on top are called the atria (say: AY-tree-uh). If you’re talking only about one, call it an atrium. The atria are the chambers that fill with the blood returning to the heart from the body and lungs. The heart has a left atrium and a right atrium.
The two chambers on the bottom are called the ventricles (say: VEN-trih-kulz). The heart has a left ventricle and a right ventricle. Their job is to squirt out the blood to the body and lungs. Running down the middle of the heart is a thick wall of muscle called the septum (say: SEP-tum). The septum’s job is to separate the left side and the right side of the heart.
The atria and ventricles work as a team — the atria fill with blood, then dump it into the ventricles. The ventricles then squeeze, pumping blood out of the heart. While the ventricles are squeezing, the atria refill and get ready for the next contraction. So when the blood gets pumped, how does it know which way to go?
Well, your blood relies on four special valves inside the heart. A valve lets something in and keeps it there by closing — think of walking through a door. The door shuts behind you and keeps you from going backward.
Two of the heart valves are the mitral (say: MY-trul) valve and the tricuspid (say: try-KUS-pid) valve. They let blood flow from the atria to the ventricles. The other two are called the aortic (say: ay-OR-tik) valve and pulmonary (say: PUL-muh-ner-ee) valve, and they’re in charge of controlling the flow as the blood leaves the heart. These valves all work to keep the blood flowing forward. They open up to let the blood move ahead, then they close quickly to keep the blood from flowing backward.
Today we learned that the heart has four chambers: two atria and two ventricles.
- The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
- The right ventricle pumps the oxygen-poor blood to the lungs.
- The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
- The left ventricle pumps the oxygen-rich blood to the body

Dr Helen Nash First Black Female Pediatrician at St. Louis Children’s Hospital
Dr. Helen Nash, a Meharry Medical School graduate and Spelman College alumna, became the first black pediatrician at St. Louis Children’s Hospital in 1949.
In her childhood days, Dr. Nash became interested in science. Nash followed her dads lead; as he was a general practitioner in the ATL. Her father was against her interest to go to medical school, nevertheless, her mother beckoned her on to follow her dreams and desires. Dr. Nash graduated from Meharry Medical School in 1945.
She began her training at historic Homer G. Phillips hospital in St. Louis, Mo. It was what many other black physicians did also.
At Homer G. Phillips, Dr. Nash immediately lobbied to the all-male hospital board to increase the number of hand washing stations at the hospital and provide new incubators for the newborns. This change strictly reduced the rate of infections and premature death rates at the hospital. She also made sure the hospital stayed cool, especially during hot summers. No, she wasn’t into heating and air conditioning, but she lobbied for these to be done. She worked with the city mayor to decrease the amount of car batteries leaking lead in the local dumpster to improve air and life quality in the community.
Dr. Nash advocated for child abuse prevention services, and was very vocal in the policy changes that led to physicians reporting mistreatment of children by parents or caretakers.
Her work led to a new job at St. Louis Children’s hospital. She was the first black female pediatrician. Dr. Nash quickly changed the nursery policy to separate newborns rather than allowing them to sleep in groups. The rates of infection, once again, decreased sharply. Her distinguished performance led to an invitation to join the staff at the Washington University School of Medicine. She was the first black woman to receive this honor.
As the first black pediatrician in a european male-dominated practice, Dr. Nash would see the discrimination against her on the patient charts, written by other doctors. When she admitted her first patient to Children’s Hospital, who was a little girl with typhoid, she found a note on the girl’s chart from a doctor that read, “too bad [Dr. Nash] started treating the patient, because now we’d never know what she had.” The comment was a deliberate accusation that Dr. Nash was improperly diagnosing her patients.
Despite the few pitfalls of racism, Dr. Nash was a well-respected physician in her community.
Dr. Helen Nash passed away in October 2012 at 91 years old
Today at MIM we learned about the different parts of the body system (shown in the previous blog :)), how to speak like a medical professional (learn more at http://www.nlm.nih.gov/medlineplus/medicalwords.html) and also we met some very amazing doctors who told us about their experience of being a medical professional, and before they were a medical professional. The people we met today included Dr. Victor from Nigeria, Dr. Holden, Dr. Andrew and Dr. Lisa Cabrera. ( Who showed us some very…. uh let’s just say GRUESOME pictures of different diseases that you would see on a rather normal day at the hospital ) Also we found out something VERY exciting! We are going to make a dance video!!! The whole purpose of this exercise is to show what dance we would do after we find out that we got accepted into the career that we love (for example me, a pediatrician :)Don’t worry, I’ll post the video on my blog! Also we got to see some rapping teachers! SAY WHAAAAT! These teachers were thebomb.com! I mean they were rapping about science! Isn’t that cool? Overall I had an AWESOME day at MIM Summer Camp! Can’t wait ’till the next class!
I would love to become a Pediatric Nurse is because, I love to take care of younger children in need. I would love to help children around the world fight different diseases or even do something as small as put a band aid on a child’s knee from playing outside 🙂 I hope to go to Lehman College in New York with a Ph.D. or bachelors degree in biochemistry, zoology, anatomy, statistics, microbiology, physiology, immunology, genetics, and cell physiology. Or at least one of these :).
Here are the 11 body systems:
