About This Chapter
MCAS STE Biology: Respiratory & Musculoskeletal Systems - Chapter Summary
Use the video lessons in this chapter to delve into the human body and gain an understanding of our major anatomical systems. After completing this chapter, you will have explored:
- Anatomy of the airways and lungs
- Process for gas exchange
- Skeletal and muscular systems
- Tissues, epithelium and multicellular organisms
- Muscle and connective tissue
- Bone tissue
- Red and white blood cells
These lessons have been created to help you easily grasp and retain the material being covered. You'll find videos with clickable timelines that allow you to re-watch a particular portion of the lesson. At the end of each lesson, you will find a self-assessment quiz that you can use to test your knowledge and gauge how questions may look on the exam.
MCAS STE Biology Respiratory & Musculoskeletal Systems Chapter Objectives
The MCAS STE Biology exam has been designed to assess Massachusetts high school students' level of proficiency in biology. There are 5 content areas tested on the exam. The lessons in this chapter will prepare you for questions related to anatomy and physiology, which account for 15% of the total score.
The MCAS STE Biology exam is comprised of 5 open-ended questions and 40 multiple-choice questions. High school students need to obtain a scaled score of 220 or higher on 1 of the 4 MCAS STE (Science and Technology/Engineering) exams to qualify for graduation.
1. Gross Anatomy of the Airway and Lungs: Conducting & Respiratory Zones
The respiratory system includes the lungs as well as other organs that help to get oxygen into the blood and carbon dioxide out of the blood. The conducting zone of the respiratory system carries oxygen into the lungs and carbon dioxide out of the lungs. The respiratory zone is where oxygen and carbon dioxide move into and out of the blood.
2. Gas Exchange in the Human Respiratory System
Did you know that the average human lung has a respiratory surface area that is roughly the same size as half of a tennis court? Believe it or not, that's how much surface area an active, healthy human needs to ensure that the body gets plenty of oxygen.
3. Skeletal System and Muscular System
Do you know how many bones are in the human body? Check out this video lesson to uncover the answer, as well as understand the role and importance of the skeletal and muscular systems.
4. Multicellular Organisms, Tissues and Epithelium
In this lesson on multicellular organisms, you'll take a look at what it actually means to be multicellular and how cells are organized into tissues, organs, and organ systems. This lesson also covers one of the four main tissue types: epithelial tissue.
5. Types of Muscle Tissue: Skeletal, Cardiac & Smooth
Have you ever wondered why muscle has different names such as striated, smooth, voluntary, or involuntary? This lesson describes the different types of muscle tissue based on their histology, mechanism of contraction, and regulation.
6. Major Skeletal Muscle Functions
Did you know that skeletal muscle does more than just move our body parts? This lesson describes how skeletal muscles are used for movement, posture, swallowing, defecation, urination and homeostasis.
7. Types of Connective Tissue
In this lesson, you'll learn about the various types of connective tissues in the body. These tissues include bone, fat, cartilage and blood. They form the framework of the body, support organs and much, much more!
8. Bone Tissue: Functions and Types
In this lesson, we will explore bone as a connective tissue. We will discuss the anatomy of bone, as well as the cell types which make up bone, including how bone is formed and broken down.
9. Functions of Red Blood Cells, White Blood Cells & Platelets
Blood is a connective tissue vital to our body's survival. In this lesson, we will explore the three functions of blood by delving into red blood cells, white blood cells and platelets - the three individual components that make up blood as a whole.
