What does physiology study?
How the body functions and works
What is the purpose of the chemical level in the hierarchy?
Atoms bond to form molecules with three-dimensional structures.
What is the second level of physiological organization?
Cellular level
What is the purpose of the chemical level in the hierarchy?
Atoms bond to form molecules with three-dimensional structures
How do physiology and anatomy complement each other?
Physiology focuses on how the body operates.
Anatomy focuses on the structure of the body.
What are the two main components of a water molecule?
2 hydrogen atoms and 1 oxygen atom
What is the fourth level of physiological organization?
Organ level
Why is understanding physiology important?
It helps learn how the body stays healthy
What is the difference between the cellular level and the tissue level?
Cellular level: A variety of molecules combine to form the fluid and organelles of a body cell.
Tissue level: A community of similar cells form a body tissue.
What is the third level of physiological organization?
Tissue level
What is the simplest level of physiological organization?
Chemical level
What is the purpose of the organismal level in the hierarchy?
Many organ systems work harmoniously together to perform the functions of an independent organism
What defines the tissue level of organization?
Similar cells forming a tissue type
What role do kidneys play in physiology?
They filter waste from the blood
What are the main components of a water molecule?
2 hydrogen atoms
1 oxygen atom
How does the cellular level differ from the tissue level?
Cellular level is molecules combining to form a cell, tissue level is similar cells forming a tissue
What is the function of the immune system in physiology?
To fight infection and protect from illness
How do all organ systems contribute to the human body?
They work together to make a functioning human
What is the resolution limit of a light microscope?
0.2 µm
What do organs work together to form?
Organ systems
What does anatomy study?
Structure of the body
How do muscles contract when running?
Physiology explains the contraction process
What is the role of tissues in physiological organization?
Tissues perform specific jobs
What is the importance of physiology in human health?
It helps maintain health and understand body functions
What are the levels of physiological organization in the human body?
Atoms
Cells
Tissues
Organs
Organ systems
Whole organism
How does physiology differ from pathology and biochemistry?
Physiology studies body functions.
Pathology studies diseases.
Biochemistry studies chemical processes.
What does biochemistry examine?
Chemical processes within the body
What systems does physiology focus on?
Heart, lungs, and brain
What is the stable body temperature maintained by physiology?
37°C
What is the final level of physiological organization?
Whole organism
What happens when things go wrong in the body?
Physiology helps explain the consequences
What is the focus of pathology?
Diseases
What happens at the cellular level of organization?
Molecules combine to form organelles
What is the role of hormones in communication within physiology?
They signal between organs
How do the kidneys contribute to maintenance in physiology?
They remove waste from the blood
What does physiology focus on?
How the body works
What occurs at the organ level of organization?
Multiple tissues combine to form an organ
How do the functions of physiology work together?
They are coordinated across levels of organization
Each function supports overall health and proper functioning
Interdependence ensures effective body responses
How does physiology contribute to understanding body functions?
It explains how the body regulates itself
What are the main components of the urinary tract system shown in the image?
Kidney, ureter, bladder, urethra
