TEAS version 7 quizlet science
1. What is the main function of the small intestine?
- A. To store food and break it down into smaller pieces
- B. To absorb nutrients into the bloodstream
- C. To produce enzymes that help digest food
- D. To eliminate waste products from the body
Correct answer: B
Rationale: The small intestine is a crucial part of the digestive system responsible for absorbing nutrients into the bloodstream. This absorption primarily occurs through the villi lining the small intestine, which increases the surface area available for nutrient absorption. Nutrients like carbohydrates, proteins, fats, vitamins, and minerals are absorbed into the bloodstream to support various bodily functions such as energy production, growth, and repair. Choices A, C, and D are incorrect as they do not accurately depict the primary function of the small intestine, which is nutrient absorption.
2. Which of the following is the main organ responsible for storing energy?
- A. Liver
- B. Heart
- C. Kidneys
- D. Adipose tissue
Correct answer: D
Rationale: Adipose tissue, commonly known as body fat, is the main organ responsible for storing energy in the form of triglycerides. It serves as a reserve of energy that can be utilized when needed. The liver primarily regulates glucose levels and stores glycogen for short-term energy needs but is not the main organ for long-term energy storage. The heart's main function is to pump blood throughout the body and is not involved in energy storage. The kidneys are essential for filtering blood and maintaining fluid balance but are not responsible for storing energy.
3. Which of the following anatomical terms is not part of the knee?
- A. Medial collateral ligament
- B. Patella
- C. Lateral malleolus
- D. Lateral meniscus
Correct answer: C
Rationale: The lateral malleolus is a bony prominence on the lateral side of the ankle and is not part of the knee anatomy. The other options - medial collateral ligament, patella, and lateral meniscus - are all structures within the knee joint. The medial collateral ligament is located on the inner side of the knee, the patella is the kneecap, and the lateral meniscus is a cartilage structure within the knee joint. Therefore, the correct answer is C, lateral malleolus.
4. What is the scientific term for scar tissue?
- A. Epithelial tissue
- B. Fibrous connective tissue
- C. Cartilage
- D. Adipose tissue
Correct answer: B
Rationale: The correct scientific term for scar tissue is fibrous connective tissue. Scar tissue is primarily composed of fibrous connective tissue, which forms as part of the body's natural healing process in response to injury or trauma. Epithelial tissue, cartilage, and adipose tissue are not typically involved in scar formation. Therefore, the correct answer is fibrous connective tissue, as it is the specific type of tissue that makes up scar tissue.
5. Which of the following structures is responsible for gas exchange in the lungs?
- A. Bronchi
- B. Alveoli
- C. Trachea
- D. Diaphragm
Correct answer: B
Rationale: The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. Oxygen from inhaled air diffuses into the blood vessels surrounding the alveoli, while carbon dioxide from the blood is released into the alveoli to be exhaled. The bronchi are air passages that carry air into the lungs but do not participate in gas exchange. The trachea is the windpipe that connects the larynx to the bronchi and serves as an airway for breathing. The diaphragm is a muscle that aids in the breathing process by contracting and relaxing to change the volume of the chest cavity.
