Structural Levels of Organization of the Human Body

Justin has learned that the mouth, esophagus, stomach, small intestine and large intestine work together. What do they combine to form?

• a cell

• organ

• tissue

• organ system

Cells are.....

• a group of tissues that together carry out a specific function

• the smallest units of all living things

• groups of organs that together carry out a specific function

• are only found in animals.

Which of the following is the correct order of organization in humans from the most basic (simple) to the most complex?

• Organismal, Cellular, Tissue, Organ, Organ System, Atom, Molecule, Macromolecule

• Atom, Macromolecule, Molecule, Organ System, Organ, Cellular, Organismal, Tissue

• Cellular, Organ, Tissue, Atom, Macromolecule, Molecule, Organ System, Organismal

• Atom, Molecule, Macromolecule, Cellular, Tissue, Organ, Organ System, Organismal

Which of the following best describes a tissue?

• a group of similar types of cells working together to perform a specific function

• a group of organs that work together to perform a specific function

• the smallest units of all living things

• a specialized unit within a cell that has a specific function

What is the difference between a cell and a tissue?

• cell is the smallest unit of life; tissue is a group of similar types of cells that work as one

• cell is basic unit of life; tissue is groups of different cells

• cell is group of tissues; tissue is basic unit of life

• cell is group of organs; tissue is group of different cells

Organs that work closely together to perform a related function is called _____________?

• cells

• tissues

• organ

• organ system

In the human body, this type of tissue is involved in movement and making facial expressions:

• epithelial

• muscle

• nervous

• connective

Lindsey tripped and cut her knee while she was competing in a track event. When Lindsey went to the doctor, the doctor told her she may have bruised her kneecap. The cut on Lindsey's knee and her bruised kneecap best represent injuries to which levels of organization within her body?

• They represent injuries to skin and bone. Skin and bone are both organs

• They represent injuries to blood and nerves. Blood is an organ and nerves are a tissue.

• They represent injuries to bone and muscle. Bone is an organ system and muscle is a cell.

• They represent injuries to blood and nerves. Muscle and nerves are both organ systems

The drawing shows the esophagus, liver, stomach, large intestine etc. What level do they represent when they work closely together.

• Organ

• Cell

• Organ System

• Tissue
