About This Chapter
Human Digestion, Respiration, Circulation & Excretion Systems - Chapter Summary
Learning about the systems of the human body can sometimes seem daunting, but these brief video lessons make it easy to reinforce what you might already know or learn new facts about various systems, including digestion, respiration and circulation. You will go over functions, terminology and diseases and conditions relating to each system. When you have completed this chapter, you should have the ability to:
- Define the digestive process and relate terms about vomiting and indigestion
- Explain the effects of too much or too little protein in a diet
- Compare the human respiratory system to that of birds, amphibians and other mammals
- Detail the gas transport function of the circulatory system
- Identify terms and causes of asthma, COPD and restrictive lung disease
- Name the parts and functions of human circulatory and excretory systems
- List the phases of the heartbeat or cardiac cycle
- Discuss types of heart conditions and diseases
- Relate information about the regulation of blood pressure
- Describe causes and effects of kidney disease
Each lesson is taught by professionals with backgrounds in medicine, anatomy and physiology education. They present the material in simple terms and use examples and illustrations. Measure the depth of your knowledge with self-assessment quizzes, use your Dashboard to keep track of which lessons you have completed and which you need to review and use an online form to contact instructors with lesson-specific questions.
1. What is Digestion? - Definition & Process
This lesson will define the process of digestion. All parts of the gastrointestinal system will be discussed. Examples will be given when possible, and you'll have an opportunity to test your knowledge.
2. Terminology of Indigestion and Vomiting
Have you ever been sick or just had too much to drink or eat? How did you feel? Maybe it made you vomit or belch. This lesson defines the terms related to all of this unpleasant feeling.
3. Health Effects Associated with Proteins
If a diet is deficient in protein, it can lead to a type of protein-energy malnutrition (PEM), such as kwashiorkor or marasmus. If a diet is too high in protein, it can lead to dehydration or increase the risk of heart disease or cancer. Learn about all of this and more in this lesson.
4. Amphibian, Bird & Mammal Respiratory Systems
While something as basic as breathing may sound universal, the fact is that amphibians, birds, and mammals all do it differently. In fact, even humans can't always control their breathing.
5. 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.
6. Terminology of COPD & Asthma
This lesson will define two famous respiratory disorders: COPD (encompassing chronic bronchitis and emphysema) and asthma (including wheezing and bronchospasms).
7. Intrinsic Causes of Restrictive Lung Disease
What does popcorn have to do with lung disease? Well, this lesson will help you find out as we venture into the world of the intrinsic causes of restrictive lung disease.
8. The Human Circulatory System: Parts and Functions
In this lesson, you will take a ride on the transportation system of the body called the circulatory system and its two parts: the pulmonary circuit and the systemic circuit. Take a look inside and see how every inch of your body receives the oxygen and nutrients it needs.
9. The Cardiac Cycle: Phases, Explanation & Terms
In this lesson, you will learn what happens during each heartbeat, or cardiac cycle. You will also learn that the heartbeat involves periods of relaxation and contraction, known as diastole and systole, respectively.
10. Types of Heart Conditions and Diseases
Your heart muscle receives a rich blood supply from the coronary arteries. If the coronary arteries become blocked, it can result in coronary heart disease, angina, heart attack or congestive heart failure. Learn how these conditions get started.
11. Excretory System
Each year in the U.S., close to 400,000 people with kidney failure undergo dialysis treatment in order to remove waste, remove excess fluid and restore electrolyte balance. Kidneys, the workhorses of the excretory system, perform these same functions more effectively than any machine. In this lesson, we'll talk about how the excretory system removes toxic substances from the body.
12. Renin Angiotensin Aldosterone System (RAAS): Pathway, Functions & Terms
The renin-angiotensin-aldosterone system is one of the most complex and important systems in controlling the blood pressure in your body. As we go over this system, you'll also learn about the many hormones involved in the control of your body's glomerular filtration rate and blood pressure.
13. Pathologies of the Kidneys
We will look at the most common conditions that affect the kidneys and their causes. The diseases that infect the kidneys will also be covered. The lesson will go over the signs and symptoms associated with each pathology.
