Levels of Organization
Life is Organized in what order
Small To Large
Which process of life is being displayed when humans sweat to cool down
Name the five basic needs for the maintenance of life
Water, food, oxygen, heat, and pressure.
What is the name of the cavity that contains the brain?
Cranial cavity
What is the anatomical position?
Must be able to Demonstrate
Standing upright, facing forward, arms at sides, palms forward
Which level of organization comes directly after cells
Which characteristic refers to producing offspring?
Reproduction
Which maintenance factor provides energy and raw materials for building new cells?
Food
Which cavity contains the heart and lungs?
Thoracic cavity
Which term means “toward the head”?
Superior
What is the simplest level of organization in the human body?
Chemical / molecular level ( Atoms )
Which characteristic is demonstrated when your body breaks down food for energy?
Metabolism (Catabolism)
Which maintenance factor removes waste products from the body?

Which body cavity contains the stomach, liver, and intestines?
Abdominopelvic cavity.
____ plane divides the body into right and left portions? _____ plane divides the body into superior and inferior parts?

What level of organization includes groups of organs working together?
Organ system.
Which characteristic OF LIFE involves the ability to sense changes in the environment?
Responsiveness.
This substance makes up about 60–70% of the human body and is required for nearly every chemical reaction
water
What organs are located in the mediastinum?
(At least)
Heart, trachea, esophagus, thymus, major blood vessels.
Differentiate between superficial and deep with examples
Superficial = closer to surface (skin is superficial to muscles). Deep = farther from surface (bones are deep to muscles).
Explain how the levels of organization progress from chemical to organism in correct order.
Chemical → Cellular → Tissue → Organ → Organ System → Organism
Give an example of how two different characteristics of life interact in everyday living.
Eating food (digestion) provides energy for muscle contraction (movement).
2 Examples where pressure is important for maintenance of life
Atmospheric pressure allows breathing; hydrostatic (blood) pressure allows circulation
Explain how the thoracic and abdominopelvic cavities are separated and why this is important
Diaphragm
important for breathing and organ compartmentalization
Which plane would show both lungs in full view?
Frontal (coronal) plane.
