Organs
What is an organ? Provide an example.
An organ is a group of tissues working together to perform a specific function. An example is the heart.
What are the main functions of the respiratory system?
The respiratory system is responsible for breathing, gas exchange, and supplying oxygen to the blood.
What is the basic unit of life?
The cell is the basic unit of life.
What is one characteristic of living things?
energy, waste, reproduction, growth, adaptation, cells
Explain the role of the lungs in the human body.
The lungs are responsible for exchanging oxygen and carbon dioxide in the bloodstream.
Identify the role of the digestive system.
The digestive system breaks down food into nutrients that the body can use for energy, growth, and repair.
Distinguish between plant cells and animal cells.
Plant cells have cell walls and chloroplasts; animal cells have only cell membranes.
Can we describe how a single cell is like an organ system?
Organisms can be described as systems made up of various parts that work together to function, like how the heart, lungs, and blood vessels work together in a human.
What tissues make up an organ?
Organs are made up of different types of tissues, including muscle, connective, epithelial, and nervous tissues.
How do body systems respond to internal stimuli?
Body systems respond to internal stimuli, like hunger, by triggering actions such as eating or hormonal changes.
Give an example of a function that cells perform in multi-celled organisms.
Cells perform functions such as energy production, growth, and repair in multicelled organisms.
List two animals and explain how they gather food and eat it differently.
Examples :Animals like birds use beaks for gathering food, while others like bears use their paws to catch fish.
How do different organs work together?
Organs work together in organ systems, such as the digestive system, where the stomach, intestines, and liver work together to process food.
Describe how the circulatory system supports other body systems.
The circulatory system transports nutrients, gases, and waste products to and from cells, supporting their functions.
How do cells contribute to the overall function of tissues and organs?
Cells group together to form tissues, which then combine to create organs that perform specific functions in the body.
What role do cells play within living things?
Cells are the basic unit of life and perform essential functions necessary for the survival and growth of organisms.
Describe how exercise impacts the functioning of organs like the heart and lungs.
Exercise strengthens the heart and improves lung capacity, leading to better oxygen delivery and overall health.
What kinds of environmental factors can impact a persons organ systems?
Factors like air quality, illness, and smoking can negatively impact the respiratory system's ability to function properly.
Describe how research on cells has improved human health.
Research has led to the development of medicines and treatments that target cell functions, improving overall health and nutrition.
Describe the similarities and differences between single-celled organisms and multicelled organisms.
Both types are made of cells, but single-celled organisms like amoebas consist of one cell, while multicelled organisms like grizzly bears are made up of many cells that perform specialized functions.
