Introduction to Anatomy and Physiology

What is anatomy?

• The study of plants

• The study of diseases of the human body

• The study of functions of living organisms

• The study of the form and structure of the parts of an organism.

What is physiology?

• The study of plants

• The study of diseases of the human body

• The study of functions of living organisms

• The study of the form and structure of the parts of an organism.

Put in order from most simple to most complex:

• Atoms, Molecules, cells, tissues, organs, organ systems, human body.

• Cells, Molecules, Atoms, tissues, organs, organ systems, human body.

• Molecules, Atoms, cells, tissues, organs, organ systems, human body.

• Atoms, cells, Molecules, tissues, organs, organ systems, human body.

One function of cells is to provide ATP to body tissues.

• True

• False

Human cells do the following: (select all that are correct)

• take in food and oxygen

• eliminate waste

• move and adapt to the environment

• Use photosynthesis

• perform special functions/each cell has a job

Mitosis results in egg and sperm cells

• True

• False

Mitosis is the process that results in cell replication and cell turn over

• True

• False

What is the body's ability to regulate its internal environment?

• metabolism

• homeostasis

• digestion

• sweating

What is the term used to describe chemical reactions constantly going on within the body's cells that result in growth, repair, energy release, use of food and secretions?

• metabolism

• homeostasis

• digestion

• sweating

Most homeostasis works on this system where conditions exceed a "set point" limit and trigger a reaction to restore the condition.

• positive feedback system

• negative feedback system
