Ch 45: Holt McDougal Modern Biology Chapter 46: Cirulatory and Respiratory Systems

About This Chapter

The Circulatory and Respiratory Systems chapter of this Holt McDougal Modern Biology textbook companion course helps students learn the essential modern biology lessons of the circulatory and respiratory systems. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Circulatory and Respiratory Systems textbook chapter.

How it works:

  • Identify the lessons in the Holt McDougal Modern Biology Circulatory and Respiratory Systems chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the circulatory and respiratory system topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Parts and purpose of the human circulatory system
  • Types of blood vessels
  • Anatomy of the heart
  • Functions of the lymphatic system
  • Functions of platelets, red blood cells and white blood cells
  • Blood types
  • Gross anatomy of the airway and lungs
  • Internal and external respiration in the lungs
  • Function of ventilation muscles

The Human Circulatory System: Parts and Functions

1. The Human Circulatory System: Parts and Functions

The human circulatory system has many parts that enable blood to move throughout the body. Learn about the circulatory system, how provides oxygen to cells, and explore the many other parts and functions, including the pulmonary and systemic circuits.

Blood Vessels: Arteries, Capillaries & More

2. Blood Vessels: Arteries, Capillaries & More

Blood vessels enable blood to flow through the body. Learn about blood vessels, including arteries, arterioles, capillaries, veins, and venules. Understand the functions of blood vessels and explore how blood backflow is prevented.

Anatomy of the Heart: Blood Flow and Parts

3. Anatomy of the Heart: Blood Flow and Parts

The heart is a complex organ that regulates a body's blood flow. Explore the anatomy of the heart and learn about its different parts, including the four chambers and heart valves, the heartbeat, as well as the process and importance of blood flow.

Functions of the Lymphatic System

4. Functions of the Lymphatic System

A healthy lymphatic system is necessary for a properly functioning cardiovascular system. Learn about the lymphatic system (lymphatic capillaries, lymph nodes, lymph, lymphatic vessels, & lymphatic drainage), the functions of each structure within the lymphatic system, and how edema occurs if the lymphatic system fails to return leaked fluids to the blood.

Functions of Red Blood Cells, White Blood Cells & Platelets

5. Functions of Red Blood Cells, White Blood Cells & Platelets

The blood is a connective tissue and it is made up of red blood cells, white blood cells, and platelets and these cells each have a specific function that helps the blood transport minerals, protect the body from germs, and heal wounds. Learn about the functions of red blood cells, white blood cells, and platelets.

Blood Types: ABO System, Red Blood Cell Antigens & Blood Groups

6. Blood Types: ABO System, Red Blood Cell Antigens & Blood Groups

Blood types are determined by antigens found in red blood cells. Learn about the blood types, red blood cell antigens, agglutination, the ABO system, the blood groups, and the definitions of universal donor and universal recipient blood types.

Gross Anatomy of the Airway and Lungs: Conducting & Respiratory Zones

7. Gross Anatomy of the Airway and Lungs: Conducting & Respiratory Zones

The respiratory system ensures the body has sufficient oxygen while removing carbon dioxide. Learn about the gross anatomy of the airway and lungs, including the upper and lower respiratory system, and explore the conducting and respiratory zones by reviewing air movement and gas exchange in the respiratory zones.

External and Internal Respiration in the Lungs: Definition & Process

8. External and Internal Respiration in the Lungs: Definition & Process

External respiration is gas exchange in the lungs while internal respiration in the lungs occurs in the metabolizing tissues. This lesson looks at the definition and process of respiration, external respiration, and internal respiration.

How Ventilation Muscles Cause Inspiration and Expiration

9. How Ventilation Muscles Cause Inspiration and Expiration

Inspiration and expiration are the processes of ventilation, which is how air enters and exits the lungs. Learn about ventilation muscles and how they cause inspiration and expiration, explore Boyle's Law, and the definitions of quiet ventilation and forced ventilation.
