Cells & Tissues
What is the basic unit of life?
Cells
An ________ is a group of tissues that work together to perform a specific function.
organ
The respiratory and circulatory systems work together by
exchanging oxygen and carbon dioxide.
_____________is the process of maintaining a stable internal environment.
Homeostasis
A model in scientific terms is a
representation of a system or process that helps explain or predict its behavior.
Name the process by which cells become specialized for different functions.
Cell differentiation
Three organs involved in the digestive system are the
The excretory system helps maintain homeostasis by
removing waste products and regulating water balance.
The body maintains temperature through interactions of different systems by
regulating blood flow and sweating.
Models help us understand how systems interact by
simplifying complex processes into visual or conceptual representations.
The relationship between cells and tissues is that
tissues are made up of groups of similar cells that work together.
Organs are grouped into organ systems based on their
functions and interactions
The muscular and nervous systems interact during physical activity by
the nervous system sending signals to muscles to contract.
The cardiovascular and excretory systems work together to regulate blood pressure by
adjusting blood volume and removing excess fluids.
An example of a model used to demonstrate the interaction of two organ systems is a
diagram showing how the respiratory and circulatory systems work together.
Tissues work together to form organs by
combining to perform specific functions.
One organ that is part of both the respiratory and circulatory systems is the
lungs
The immune system protects the body by
identifying and attacking pathogens.
The nervous system processes information from the environment by
receiving sensory input and sending signals to the brain.
Evidence that might support the argument that organ systems work together includes
observations and data showing their interdependence.
Stem cells can develop into different types of tissues through the process of
differentiation
The heart functions as part of the cardiovascular system by
pumping blood throughout the body.
The digestive and circulatory systems collaborate by
absorbing nutrients from digested food and transporting them to cells.
The importance of cellular respiration in providing energy for life processes is that it
converts glucose and oxygen into ATP, which powers cellular activities.
Developing models can lead to greater understanding of biological interactions by
allowing scientists to visualize and test hypotheses about system functions.
