Transport and GASEOUS EXCHANGE transport
In this chapter we learned about different mammalian transport systems and the components of these different systems. The gaseous exchange system links the circulatory system with the atmosphere.
It is adapted to
It is adapted to
- Clean and warm the air that enters during breathing
- Maximize the surface area for diffusion of oxygen and carbon dioxide between the blood and atmosphere
- Minimize the distance for this diffusion
- Maintain adequate gradients for this diffusion.
This was a Prezi presentation a group of students and I made dealing with this gaseous exchange unit. This presentation talks about the risks of smoking and the components of smoke's effect on the human's gaseous exchange system.
Gas exchange in humans
The Lungs
Lungs are the site of gaseous exchange between air and blood and they present a huge surface area to the air that flows in and out. They are in a chest cavity. The lungs are ventilated with air which passes through a branching system of airways.
Essential vocabulary
252. ALVEOLI - Any of the many tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place
253. TRACHEA - Each of a number of fine chitinous tubes in the body of an insect, conveying air directly to the tissues
254. GOBLET CELLS - A column-shaped cell found in the respiratory and intestinal tracts, which secretes the main component of mucus.
255. CILIATED EPITHELIUM – surface tissue with cilia on it
256. RESIDUAL VOLUME – air, which still remains in the alveoli and the airways
257. BRONCHUS - Any of the major air passages of the lungs that diverge from the windpipe
258. RESPIRATORY BRONCHIOLE - The respiratory bronchioles are interrupted by alveoli, which are thin walled evaginations

Transport in plants
Plants like animals need a constant and regular supply of oxygen and nutrients. Plants need things such as carbon dioxide, oxygen, organic nutrients and inorganic ions and water. Plants have two transport systems: one for carrying mainly water and inorganic ions from roots to the parts above ground, and one for carrying substances made by photosynthesis from leaves to other areas.
This was a vocabulary assessment we took during class to test how much important terms we retained during class lectures.
This was a webquest we did on the unit at hand. It helped reinforce information given during the chapter and prepared us greatly for the upcoming chapter test.
This was a lab we did during the transport in plants unit. We dissected a carrot and examined the internal structures.

This also was a vocabulary assessment we took during class. This was a chapter ahead of the gaseous exchange but many terms were linked by relevance.
This is the unit test from the transport in plants unit. I received an 85% on the test meaning i mastered a large portion of the unit.
This was the unit test for the gaseous exchange unit. I had received an 88% on this test.
