pee

DID YOU KNOW


That urine leaving a healthy body is odourless? And also, urine leaving a healthy body is sterile! Surprising. It does contain metabolic wastes and salts and fluids, but it doesn't contain bacteria or viruses or fungi. In fact, the smell of urine is actually due to bacteria in the air reacting with the urine, converting some of the chemicals in urine to smelly chemicals such as ammonia.

Playland post FROM THE PAST

So here is an overdue playland post, with pictures! I only went on one ride (I was hacking and coughing all day) so I was often left watching...people's....stuff (EXHILARATING) but I did go on the wooden rollercoaster, so I'll base my question answers off of that experience.

1. Heart Rate: Waiting in line is almost always the toughest part- you're waiting in anticipation, and you're getting nervous. Your heart is beating fast because you're dragging on the fear. My heart rate app didn't really work all that well, but while I was on the ride, I did feel my heart beat insanely.

2. Breathing rate: Some people either hyperventilate, or hold their breath. I ended up holding my breath- I was almost too scared to breathe (well, I was nearly falling out of the rollercoaster...).

DID YOU KNOW (respiratory system version)

Did you know that breathing through the mouth is a no-no?

Breathing through the mouth can cause your jaw to shrink, which can cause crooked teeth or relapse after having braces removed. It's also the biggest cause of children developing lisps when they're young. Additionally, when you breathe through your mouth, your bladder shrinks- which is why a lot of people get up in the middle of the night to use the bathroom. 

So...don't breathe with your mouth. That's bad.

so I totally did not procrastinate sort of

Getting around to finishing all the drafts I've got back here. So...expect spam.

The blood cell's JOURNEY OF LIFE

Legend: Deoxygenated, Oxygenated

The blood cells flow through the common carotid artery, to the brain. There, the oxygen is drawn out of the blood. The now deoxygenated blood flows down through the jugular veins, then into the superior vena cava, and into the heart. There, it flows into the right atrium, and is pumped through the AV (atrioventricular) tricuspid valve, and into the right ventricle. Next, it is pumped through the pulmonary semilunar valve, and into the pulmonary trunk. The deoxygenated blood goes through the pulmonary arteries, and into the lungs. Gas exchange occurs, and the blood becomes oxygenated. It goes into the heart through the pulmonary veins, and into the left atrium. It goes through the AV bicuspid valve, into the left ventricle, through the aortic semilunar valve, then finally into the aorta, to the body. 

Pulmonary vs. Systemic

- transports deoxygenated blood to the heart, then the oxygenated blood back to the heart
- pulmonary arteries and veins

- Heart pumping blood to the rest of the body through the aorta
- Superior/Inferior Vena Cava


Arteries and Veins

- thick walls
- carry oxygenated blood
- blood away from heart

- thin walls
- valve to prevent blood flowing backwards
- carry deoxygenated blood
- blood towards to heart

Fetal Circulation

There are 3 major modifications to the fetal circulatory system-

Formenovale  - A hole in the fetus' heart which allows blood to bypass the lungs

Ductus Venosus - Oxygenated blood from the placenta goes through the Ductus Venosus, then to the inferior vena cava

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

Boy you've got my heartbeat runnin' away.....

Our heart is pretty strong.

DID YOU KNOW...


That daily, a heart creates enough energy to drive a truck 20 miles?

WHAAAAAAAAAAAAAAAAAT?


And if you measured the amount of energy over a lifetime....you'd have enough energy to go to the moon and back?



WHAT????!!!?!???!?!?!


The heart is pretty powerful, isn't it?

engaged (insert wedding theme)

At first glance, I don't seem very engaged.
I don't participate in discussions often, and I don't ask questions often.

I'm the kid that makes eye contact and nods
:'( I'm shy! I don't like talking very much because i'm awkward and quiet and I stutter and ....insert awkwardness here. And i'm definitely behind in my blog, but i'm a good student, I promise! I just....show it in unconventional ways.

I really do enjoy class discussions, and I enjoy having question periods! While i may not ask much, I do listen.









And for the record, I've only dozed off in class once!
