Key Concepts

Alveolus

Minute air sacs in the lungs where the crucial process of gas exchange occurs, allowing oxygen to enter the blood and carbon dioxide to be expelled.

Trachea

A key structure in respiratory anatomy, the trachea is a rigid tube that serves as the primary airway passage, channeling air from the upper respiratory tract down to the lungs.

Pharynx

This muscular tube forms part of the throat and functions as a pathway for both air and food, linking the nasal and oral cavities to the larynx and esophagus.

Hemoglobin

An essential respiratory protein found in red blood cells, hemoglobin binds to oxygen in the lungs and transports it throughout the body, playing a key role in cellular respiration.

Bronchus

These are the larger airway passages that branch from the trachea into the lungs, directing air to various regions of the lung tissue.

Bronchiole

Representing smaller subdivisions within the bronchial tree, bronchioles further channel air to the alveoli and help regulate air distribution in the lungs.

Glottis

A component of the larynx, the glottis is the opening between the vocal cords, important not only for voice production but also for regulating airflow during breathing.

Diaphragm

A dome-shaped muscle that plays a critical role in respiration by contracting and relaxing to create the pressure changes necessary for inhaling and exhaling air.

Transcript

00:02 Okay, so today we're going to start with respiration and we're kind of just going to be doing kind of like a define certain terms.

00:13 We have eight terms here.

00:17 It looks like we're going to be defining.

00:20 So we can start from the top and work our way down.

00:23 It will work with me here.

00:25 So we're going to start with the trachea, which is your windpipe.

00:33 It's different from your esophagus, it's your windpipe because that's where the air and the food split off from each other.

00:47 And of course, your pharynx, which is where your windpipe and all of that stuff lives, is also known as your throat.

01:00 Moving down, we have the alveolus, that is a v, not a u.

01:06 Let me correct that a little bit.

01:09 V, not a u.

01:12 Of course, so that is where gas exchange occurs.

01:18 It is defined as the site of gas exchange, and that is where the gases you inhale, mainly, oxygen, i would hope so, comes in while the gases you exhale, which would be your co2, goes out.

01:47 So there's kind of a little transition point in there.

01:51 Your hemoglobin is part of your respiratory system, but it's not like a full organ or anything.

01:58 It is a special respiratory protein that helps with making sure everything goes properly.

02:20 Next we have your bronchus, which is the airway.

02:27 So you've got your tibus.

02:30 You've got your trachea, which is your windpipe, but then from there it branches off and goes down.

02:39 And then, of course, your lungs, you have two.

02:42 Essentially, you have two different compartments in your lungs.

02:45 You have the left and right.

02:46 So, of course, you've got to have ways to get into that.

02:50 So that is what the bronchus is.

02:52 That is hold up.
