- The maintenance of a stable internal environment in the body is homeostasis.
- What is a collection of tissues that work together to carry out a specialized function in the body?
c. an organ - Muscle tissue helps your stomach digest food by c. breaking up food.
- What can happen to cells if homeostasis is disrupted?
If homeostasis is disrupted, cells may become damaged or function improperly, leading to illness or disease. They might swell or shrink, depending on changes in their environment, and metabolic processes can become unstable, impacting overall body function. - How is your body like a soccer team?
Your body is like a soccer team because various parts (like organs and systems) work together towards a common goal of maintaining health and function. Just as players have different roles (defense, offense, etc.), different cells, tissues, and organs have specialized functions that contribute to the overall performance of the body. Teamwork and coordination are essential in both scenarios for effective outcomes. - A group of similar cells working together forms a(n) tissue.
Match the correct description with the correct term: - joins, supports, and insulates organs - d. connective tissue
- covers and protects underlying tissue - c. epithelial tissue
- sends electrical signals through the body - a. nervous tissue
- produces movement - b. muscle tissue
- How does your body know when your stomach is full?
Your body knows when your stomach is full through signals sent by stretch receptors in the stomach wall that communicate with the brain, along with hormonal signals that indicate fullness. These signals inform the brain to reduce appetite and stop food intake. - The wall of the stomach contains blood and another connective tissue called collagen.
- The inside of your stomach is lined with epithelial tissue.
- Organs that work together make up a(n) organ system.
Match the correct description with the correct term: - includes the heart, blood vessels, and blood - circulatory system
- removes wastes from blood - excretory system
- sends out chemical messages - endocrine system
- includes skin, hair, and nails - integumentary system
- supports and protects body parts - skeletal system
- helps get rid of bacteria and viruses - immune system
- absorbs oxygen through the lungs - respiratory system
- breaks down food into nutrients - digestive system
- helps the body move - muscular system
- produces eggs and protects the fetus - reproductive system
- sends and receives electrical messages throughout the body - nervous system
- How do organ systems work together to maintain homeostasis? Give an example.
Organ systems work together to maintain homeostasis by coordinating their functions to respond to changes within the body and its environment. For example, when you exercise, the muscular system works to provide movement, while the respiratory and circulatory systems increase oxygen and nutrient delivery to the muscles, and the sweat glands (part of the integumentary system) help cool the body to maintain a stable internal temperature.
