When ready, assess your comprehension of the lessons using this chapter's short quizzes and practice exam. All resources in this chapter are accessible 24/7 using any computer, smartphone or tablet with an Internet connection.
1. Blood: Function & Components
You know your heart pumps blood through your blood vessels, but do you know why this is important? Learn why your blood must keep moving, as well as the things that make it up, like plasma, red blood cells, white blood cells and platelets.
2. What Is the Composition of Blood?
This lesson is going to cover the materials of which blood is composed. We will explore the parts that make up the solid and liquid portions of blood and discuss how these are maintained.
3. How Blood Travels Throughout the Body
This lesson is going to cover the different blood vessels that carry blood throughout the body. The route and changes in blood pressure will also be discussed. A short quiz will follow.
4. Gas Transport: Oxygen and Hemoglobin
Did you know that almost all of the oxygen transported in our blood is bound to hemoglobin? Hemoglobin is loaded with oxygen in the lungs and unloaded of oxygen in the metabolizing tissues. This lesson will describe how oxygen is transported in our blood.
5. Gas Transport: Cooperative Binding of Oxygen with Hemoglobin
Our cells need oxygen. Most of the oxygen is delivered to our cells bound to hemoglobin. This lesson describes how cooperative binding of hemoglobin maximizes oxygen delivery to our metabolizing tissues.
6. Carbon Dioxide Transport in the Blood
While carbon dioxide is a metabolic waste product, it plays some important physiological roles as well. This lesson describes how carbon dioxide is transported in our blood, how carbon dioxide is converted into a pH buffer, and how carbon dioxide helps with oxygen transport.
7. Blood Vessels: Arteries, Capillaries & More
In this lesson, you will take a trip around the circulatory system and encounter the various blood vessels, including arteries, veins, and capillaries. Come along as we follow the path to every cell of your body.
8. Capillary Fluid Exchange
How do we get nutrients from blood into the rest of our bodies? The answer is through capillary fluid exchange, and in this lesson we'll discuss what this process is and how it works. Then, test your understanding with a brief quiz.
9. Lipids Digestion and Absorption
Lipids, or fats, are digested and absorbed in the small intestine. In this lesson, you will learn how bile salts emulsify fat so pancreatic lipase can digest it. You will also learn how fats first enter lymphatic capillaries, called lacteals, before entering your blood circulation.
10. Structure of Plant Stems: Vascular and Ground Tissue
You can determine the age of a tree by looking at its rings. In this lesson, we will look at the basic structures of stems and explore what causes the rings in a tree trunk.
11. Xylem: The Effect of Transpiration and Cohesion on Function
Roots absorb water and leaves release water, but how does water move up a plant? In this lesson, we will look at how this happens in vascular plants, including the importance of xylem, cohesion and transpiration in the process.
12. Phloem: The Pressure Flow Hypothesis of Food Movement
Leaves produce sugars and stems; roots and fruits use these sugars for energy. In this lesson, we will look at how these sugars move throughout vascular plants, including the importance of phloem and the pressure flow hypothesis in the process.
