Anatomy and Physiology B/C

Postby BasuSiddha23 » September 20th, 2017, 7:18 pm

Start off with something basic:
1) Describe how oxygen enters the bloodstream and its path
2) What are the "pipes" in the lungs referred to as?
3) Name two differences between the left lung(remember, in the person's perspective) and the right lung

1. Oxygen enters the blood through the lungs, attaches to hemoglobin in the blood. CO2 is knocked off of the hemoglobin and is exhaled. As the blood moves to lower concentrations of oxygen, CO2 will knock oxygen off of the hemoglobin and replace it. Carbonic acid is split into a bicarb and protons, and the protons also replace oxygens in hemoglobin (Bohr effect). The blood returns to the lungs and oxygen knocks off the CO2 and protons; the protons and bicarbs reform carbonic acid, which then becomes CO2 and water (Haldane effect)
2. Primary bronchi, secondary and tertiary bronchi, or bronchioles
3. The left lung has two lobes as well as the mediastinum, right lung has three lobes

I believe you did get it right. Great job!
I was also going for how the oxygen gets to the bloodstream from the lungs, which is by simple diffusion through the ends of the bronchial trees called alveoli.

Ok. Your turn.

Since no one has posted recently, I'll just ask a question...

Define lung compliance and 2 factors that affect it.

Lung compliance is the lung's ability to stretch and expand.

Two factors that affect it are fibrosis and pulmonary hypertension.

Fibrosis is when the tissue around the alveolar sacs thicken and become scarred. This makes it harder for oxygen to diffuse into the blood

Pulmonary hypertension is when capillaries and arteries close to your lungs become narrowed, blocked, or destroyed due to high blood pressure.

Hi,

When you say "factors", I would assume you mean general properties rather than specific disorders?

In this case, two major factors that affect lung compliance are elasticity (thickening of the tissues of the lungs leads to decreased compliance) and surface tension (the water lining the alveoli leads would lead to a very low lung compliance if not for surfactant).

(Increased compliance means the body doesn't have to exert as much force to cause any given change in lung volume.)

Yes, I was going for properties that would affect lung compliance, not anything too specific.
Either of you can post.

I posted since nobody else was.

Using what you know about the lungs and how they developed in the human body, please explain why it is better to breath through your nose as opposed to your mouth when running.

Maybe???
breathing through the nose warms the air in the nasal cavity
You breathe slower since air can't get in as quickly, so more gas exchange can take place per breath

I was actually looking for the fact that the lung is a wet organ that evolved from a fish like ancestor and the nose moisturizes air when it breaths it in, allowing for more efficient breathing.

I guessed on a lot of these but here goes...
1. Negative selection
2. Tidal volume, inspiratory reserve volume, expiratory residual volume, and residual volume. (I hope I spelled that all right. )
3. Transpulmonary pressure
4. Simple diffusion
5. Pyloric Spincter
6. Cardia, fundus, corpus, and pyloric.
7. Myenteric plexus
8. 6-8 hours. It varies between people of different sizes.
9. Hepatic portal vein
10. Some parts of your immune system work better at higher temperatures, making a fever beneficial to you, not just some annoying symptom.
