Engagement: no ring needed though it is encouraged

How am I engaged in class...

I would say I am engaged in a different way than others. I am not the type to speak up and ask questions or put in my opinions and thoughts, but I do believe I am engaged in class. 

I like to ask other people in the class questions about what we learn. I also feel like telling my peers what I know helps me learn the topics more. When we share each other's knowledge, I feel I'm encouraged to do just as well as my friends.

I'm the quiet student in the background that stares, laughs when others laugh, and concentrate when others concentrate. I nod my head when I understand and try to make my notes neat so I can read them for review. When I am really stuck, I would ask for teacher help, but that doesn't happen too often because I would ask friends or look in my notes for the answer. 

I am not the extrovert that blurts out my ideas. I don't freely share my thoughts with the rest of the class. And although I don't do those things, my engagement in class is not less than those who do. 

Pee-pee System and A Lot of Sciency Stuff

Hello, we are Keara Laing and Amber Togado.
Here is our little slideshow of photos where we explain the urinary and kidney systems.

Urinary System
What is a Urinary Tract Infection?

UTI is an infection that infect your urinary tract. It causes painful urination and the urge to urinate, or urinate very often. It can also cause fever, or tummy pain. UTI is mainly caused by a bacteria called Escherichia Coli (E. Coli), but it can also be (rarely) caused by other viruses or bacteria.

UTI is more common in women, and reinfection is common as well.
UTI is treated with a short course of antibiotic medicine, but since resistance to the antibiotics is becoming greater, longer courses of antibiotics or other treatment is needed.

When you have UTI, you may pee out urine with pus. PUKEPUKEBLEHHHH

Circulation System Review hnggggggg

Pulmonary:
- pulmonary arteries and pumonary veins.
- transport deoxygenated blood to the lungs, and then take oxygenated blood to the heart.
- pulmonary arteries take deoxygenated blood to the lungs to be oxygenated, pulmonary veins take oxygenated blood back to the heart.

Systemic:
- aorta, superior vena cava, and inferior vena cava.
- heart pumps oxygenated blood through the aorta to be pumped through the rest of the body. 
- deoxygenated blood from the body comes in through the inferior and superior vena cavas to be pumped to the lungs for oxygenation.

Arteries:
- thicker walls
- carry oxygenated blood

Veins:
- thinner walls
- have valves that prevent blood backflow
- carry deoxygenated


Blood Flow:
1) carotid artery - oxygenated
2) jugular vein - deoxygenated
3) superior vena cava - deoxygenated
4) right atrium, av valve - deoxygenated
5) right ventricle - deoxygenated
6) pulmonary semilunar valve, pulmonary trunk/artery - deoxygenated
7) lungs - deoxygenated, gets oxygenated
8) pulmonary veins - oxygenated
9) left atrium, av valve - oxygenated
10) left ventricle - oxygenated
11) aortic semilunar valve, aorta - oxygenated

Fetal Circulation:
Foramenovale - a hole in the fetus heart between the right and left atrium, where blood moves through to bypass the lungs because they are not needed for a fetus in the womb.

Ductus Arteriosis - hole between aorta and pulmonary trunk for blood to, again, bypass the lungs.

Ductus Venosus - oxygen rich blood from the placenta goes through the ductus venosus and in through the inferior vena cava to be pumped through the heart.

I show you my intelligence by answering these questions

1. Compare the structure of the atria and ventricles - how are they different? Why is that?

The left ventricle is larger than the right ventricle because the left ventricle must pump blood to the whole body, while the right ventricle needs only to pump blood to the lungs.
The atriums are smaller than the ventricles because the atrias only need to pump blood to the ventricles, and the ventricles must pump blood to the lungs and the entire body.

2. Did you notice a difference between the veins and arteries entering and leaving the heart? How is their structure different?



3. Describe the valves that you found in the heart - what are their functions?

Tricuspid Atrioventricular (AV) Valves: valves between right atrium and right ventricle.
Mitral/Bicuspid Atrioventricular (AV) Valves: valves between left atrium and left ventricle.
Both AV Valves control the flow of blood between the chambers and keep blood from flowing backwards.
Both also have strong and fibrous strings called chordae tendineae that support the valves and keep them from inverting.

Pulmonary Semilunar Valve: valves between the pulmonary trunk/artery and right ventricle.
Aortic Semilunar Valve: vales between the left ventricle and aorta.
Both semilunar valves are crescent moon-shaped and also prevent back flow of blood into the ventricles.

4. What surprised you about dissecting the heart? Why?

I was surprised that there was so much chordae tendineae and valves to look at and see because I believed they would be slightly larger and have a much less quantity. I was also surprised at how strong the valves were. They looked really thin, but when felt they were very stretchy and tight.
I was surprised that the arteries and veins were so difficult to spot and see which was which. I expected them to be easy to point out because its obviously much easier on paper, but on the real thing it was really hard.

This is a silent video

Ella this is Anna and I's video about blood flow in the heart... it is silent because there is no sound and it is a little asks.
We are kind of missing the semilunar valves but they are the crescent moon shaped flaps (one at the opening of the pulmonary artery and one at the ending of the aorta) that prevent back flow of blood.
Oxygenated blood moves in through the pulmonary vein, through the left ventricle and atrium, and out through the aorta.
Deoxygenated blood moves in through the inferior and superior vena cavas, through the right ventricle and atrium, and exits out the pulmonary artery.
Arteries take blood away from the heart, while veins return the blood to the heart.
