Overview of Gaseous Exchange
Chapter 8 discusses the mammalian transport system of oxygen and blood. Mammals have a double circulatory system which is the combination of pulmonary circulation and systematic circulation. Blood is able to be transported throughout the body because of the heart. The blood is carried away from the heart in arteries and become very narrow tubes that pass through tissue called capillaries. The capillaries then become larger again forming veins that return the blood to the heart. Another important topic discussed in this chapter was how red blood cells carry oxygen. The haemoglobin in the red blood cells absorbs the oxygen in the lungs and then releases it at low partial pressures of oxygen in respiring tissues.
Chapter 10 describes the transportation system in multicellular plants. Like animal cells, plant cells need a regular supply of oxygen and nutrients, but they obtain these matters differently. Water, for example is transported through the plant's xylem vessels. Water enters the root by osmosis in the soil, crosses the root by either the apoplast pathway or symplast pathway, and it then enters into the xylem vessel. Due to pressure differences caused by the loss of water from transpiration in the leaves, the water is able to move up the xylem. Transpiration was another key term in this chapter. Transpiration is the loss of water vapor from the leaves of a plant. Plants have air spaces in the leaves called stomata that allow carbon dioxide and oxygen to be exchanged with the environment.
Chapter 12 described how smoking effects the lungs and causes various diseases. Cigarettes are the most smoked product in the world an are made of tobacco. The three main componentes in cigarettes are tar, nicotine, and carbon monoxide. Additionally, scientist have discovered over 4000 chemicals used in the production of this habit. Many of these chemicals caused cancers that would usually result in a slow, cruel death. Patients who smoked typically had symtoms like shortness of breath, frequents colds, and chest pains. Chapter 12 was also full of facts and statistics to deter students from using the deadly product.

Chapter 8: Mammalian Transport System Vocabulary Quiz
I got a 100% on this vocabulary quiz.
Carrot Lab Report
In this experiment I was asked to cut a carrot open and observe its transport system. I had to identify the phloem, xylem, and vascular cambium and describe their function in the carrot and I got a 100%.

Review Packet
The picture to the left are some questions I had to answer with the review packet, "gaseous exchange".
AICE Example Questions
On this difficult exam, I scored an 80%. It was supposed to simulate an actual AICE test and I was deducted some points for not fully answering a question and not plotting the point on the graph correctly.
