Unit 1
Introduction to the human body
Watch the video below: Unlocking the Mystery of Life, 4 min.
The basic idea: You are not a random assemblage of molecules. You were created in the image of a living and personal God, who obviously loves to design and create incredibly beautiful and complex living things! The last 50 years - 25 years actually - has shed light on the inner workings of the cell and tissues that allow us to see with incredible detail how this "design" plays out. This gives us even more reason to study Anatomy & Physiology - because in doing so we are learning about the "eternal power and divine nature" of our creator.

Ch. 1 Introduction
How to approach each lesson
- Start by reading the 'lecture outline' below.
- Then flip through the chapter and study the pictures. This textbook has excellent pictures, so start with that.
- Then go back and read the sections that correspond to the "lecture outline" below. We aren't covering every single topic in the book.
- Use 3x5 'recipe cards' to make lists of terms. Develop an organized system for studying!
- We will cover everything again at class, and you can ask questions and there will be class discussion.

Lecture outline
You won't be required to memorize all this information, but you do need to know what it means. Don't worry, we will discuss these many times in the class...
Anatomy and Physiology deals with the structure & function of the human body
Levels of organization in the body

Anatomy and Physiology deals with the structure & function of the human body
- Anatomy = structure (of each part)
- Physiology = function (of each part)
Levels of organization in the body
- Chemistry - atoms form the molecules of life
- Cells - molecules combine to form cells; the basic unit of all life
- Tissues - groups of similar cells form tissues; bone tissue, skin, muscle tissue, etc
- Organs - groups of tissues form organs; the heart, lungs, pancreas
- Organ systems - groups of organs form systems; for example the heart, lungs, and blood vessels form the cardiovascular system
The "Eleven Systems" of the human body. At this point, you just need to know what the terms mean. Throughout the course, we will cover each one in turn
Homeostasis
- Integumentary system (skin)
- Skeletal
- Muscular
- Nervous
- Endocrine (hormone producing glands)
- Cardiovascular
- Lymphatic (lymph vessels, nodes, spleen, immune system)
- Respiratory
- Digestive
- Urinary
- Reproductive (to be covered at home with parents)
Homeostasis
- This is a word you will encounter a lot, and means "equilibrium". The body maintains equilibrium through feedback systems, the nervous system, signaling molecules (hormones), and various receptor cells which monitor temperature, blood pressure, blood glucose, and many other things.
The "anatomical position"
Some directional terms you will eventually need to recognize
- This is where the human subject is depicted standing upright, facing the observer, with palms turned forward.
Some directional terms you will eventually need to recognize
- Superior = above
- Inferior = below
- Anterior = front
- Posterior = back
- Medial = nearer the midline
- Lateral = farther from the midline
- Proximal = nearer the body trunk
- Distal = farther from the body trunk
Body planes which the book uses
- Sagittal, Frontal, Transverse
Body cavities. The basic 6 are listed:
- Cranial
- Vertebral
- Thoracic
- Abdominal
- Pelvic
- Also know where the diaphragm muscle is located
