Alveoli
|
Thin air sacs that are sites for gas exchange between environment and the blood via passive diffusion.
|
|
What is the pleurae?
|
The outer lining of the lungs. It is filled with pleura fluid that lubricates the lungs.
|
|
What is the trachea?
|
Is the region of the air intake pathway between the glottis and the bronchi.
aka. windpipe. |
|
Oxygen content is greatest in the fluid, in which structure?
|
The left ventricle.
|
|
Pulmonary Vein
|
Only vein that carries oxygenated blood.
It is released in the left ventricle. |
|
Pulmonary Artery
|
Only artery that is deoxygenated blood.
On its way to the lungs to be oxygenated. |
|
Thoracic Duct
|
- Lymph vessel
- Returning lymphatic fluid back to the venous circulation. |
|
Right Atrium
|
- Low O2 content.
- Blood returning from body is collected here before heading to the lungs. |
|
Inferior Vena Cava
|
Returns deoxygenated blood to the heart.
|
|
Medulla Oblongata
|
|
|
The Cerebrum
|
Sensory interpretation, memory, and thought.
|
|
The Hypothalamus
|
Regulates
|
|
The Cerebellum
|
|
|
Hydrostatic Pressure
|
|
|
Osmotic Pressure
|
|
|
Starling's Hypothesis
|
All of the fluid cannot be returned to the vessel. Instead some of the fluid travels in to the interstitial spaces until is picked up lymphatic system where it is filtered through the lymph nodes and returns to the circulatory system via thoracic duct.
|
|
Epiglottis
|
The cartilaginous structure that prevents food from going down the trachea.
|
|
Glottis
|
The opening at the top of the trachea that is closed by the epiglottis.
|
|
Larynx
|
- aka. Voice box
- Located below the glottis. |
|
Esophageal Sphincter
|
- aka. Cardiac Sphincter
- Separated the esophagus from the stomach. |
|
How is Carbon Monoxide be lethal?
|
Like O2, CO2 is attracted by hemoglobin molecules. Carbon monoxide binds to hemoglobin strongly, and its almost irreversible.
|
|
Passive Process
|
1. Exhalation
2. Gas Exchange |
|
Exhalation
|
- Passive process
- Relaxation of both diaphragm and the external intercostal. |
|
Gas Exchange
|
Gases diffuse their partial pressure gradient.
|
|
Inhalation
|
- Active process
- Contraction of the diaphragm and external intercostal. |
|
Describe Veins
|
|
|
Blood Flows
|
Depends on compression between neighboring skeletal muscles.
|
|
Blood Components |
Cells

|
Blood Cells |
Erythrocyte (RBC)
Leukocytes (WBC)
Thrombocytes (Blood Clot) |
|
Plasma |
|
|
Blood Type |
Your blood type equals the antigen you will recognize.
|
