Levels of Organization
This is the smallest chemical unit of matter.
What is an atom?
This system includes the heart and blood vessels and transports oxygen and nutrients throughout the body.
What is the Circulatory (cardiovascular) system?
In the standard anatomical position, the palms of the hands face which direction?
What is forward/anterior?
This region is located directly above the stomach, in the center of the top row.
What is the epigastric region?
This type of feedback loop reverses a change in the body to maintain stability, like regulating body temperature.
What is negative feedback?
Two or more atoms bonded together form this level.
What is a molecule?
This system protects the body, helps regulate temperature, and includes skin, hair, and nails.
What is the integumentary system?
This plane divides the body into anterior (front) and posterior (back) parts.
What is the frontal plane?
This region refers to the upper arm, between the shoulder and elbow
What is the brachial region?
This type of feedback loop enhances or amplifies a change, like the release of oxytocin during childbirth.
What is positive feedback?
Organelles inside these structures allow life processes to occur. They are the smallest unit of life.
What is a cell?
This system breaks down food into nutrients that can be absorbed by the body.
What is the digestive system?
The elbow is __________ to the shoulder but __________ to the wrist.
What is distal to the shoulder but proximal to the wrist?
This region is located directly below the stomach, in the center of the bottom row.
What is the hypogastric region?
In a feedback loop, this component detects changes in a variable (like temperature or blood sugar) and sends information to the control center.
What is a receptor?
This level consists of groups of similar cells working together to perform a common function.
What is a tissue?
This system is made up of glands that secrete hormones to regulate body processes.
What is the endocrine system?
This directional term means “toward the midline of the body,” while its opposite means “away from the midline.”
What are medial and lateral?
This region is on the lower left side of the abdomen, above the left leg.
What is the left iliac (inguinal) region?
In a feedback loop, this component receives information from the receptor, processes it, and determines the response.
What is the control center?
Place the following in the correct order from simplest to most complex: molecule, tissue, organ, cell, organism, atom, organ system
Atom-> Molecule-> Cell-> Tissue-> Organ-> Organ system-> Organism
This system supports and protects the body, provides attachment for muscles, stores minerals, and makes blood cells.
What is the skeletal system?
The thumb is __________ to the pinky, and the knee is __________ to the ankle.
What is lateral to the pinky, and proximal to the ankle?
Which of the following regions is not located in the lower half of the abdomen: Right Iliac, Hypogastric, Umbilical, Left Iliac?
What is the Umbilical region? (It’s in the middle row, not the lower row)
This component of a feedback loop carries out the response, like muscles contracting to generate heat or glands secreting hormones.
What is the effector?
