Anatomy, and Physiology: Chapters 1.2-1.6

Which sequence correctly represents the levels of organization in the human body?

• Atom → Macromolecule → Molecule → Organelle → Cell → Tissue → Organ → Organ system → Organism

• Atom → Molecule → Macromolecule → Organelle → Cell → Tissue → Organ → Organ system → Organism

• Atom → Cell → Tissue → Organ → Macromolecule → Organ system → Organism

• Atom → Organelle → Molecule → Organ → Organ system → Tissue → Organism

Which of the following statements about the levels of organization is true?

• Cells are composed of tissues.

• Tissues are smaller than organelles.

• Organs are made up of two or more tissues working together.

• Organ systems are less complex than organs.

Which is the simplest level of organization in the human body?

• Atom

• Cell

• Tissue

• Organ

Which level of organization is defined as a group of similar cells performing a specialized function?

• Organ

• Tissue

• Organelle

• Macromolecule

Which level of organization consists of very large molecules, such as proteins and nucleic acids?

• Atom

• Molecule

• Macromolecule

• Organelle

Anatomy is best defined as:

• The structure and organization of body parts

• The study of the body's chemical processes

• The continuous regulation of body systems

• The function of anatomical parts

Physiology is best defined as:

• The form of body parts

• The functions of anatomical parts

• The chemical composition of matter

• The study of cavities and membranes

Which of the following statements about the study of the human body is true?

• Anatomy examines structure; physiology explains function.

• Physiology studies organs only; anatomy studies cells only.

• Anatomy and physiology are unrelated fields.

• Physiology describes only microscopic detail, not body systems.

An organ differs from a tissue in that an organ:

• Contains only one cell type

• Is made up of two or more tissues working together

• Is the structural and functional unit of life

• Is less complex than a cell

What does Movement mean?

• Changing body position or moving internal parts.

• Sensing and reacting to internal or external changes.

• Increasing size without changing shape.

• Producing offspring.

• Nutrient cycling and energy production; it includes: respiration, digestion, circulation, and excretion.
