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.
