An Introduction to the Structure and Function of the Body Flashcards

A complete 200-card vocabulary study set covering Chapter 1: An Introduction to the Structure and Function of the Body.

Anatomy

The study of the structure of the body and its parts.

Physiology

The study of how the body and its parts function.

Relationship between Anatomy and Physiology

A body part's structure affects how it functions, so anatomy and physiology work together.

Primary Concern of Anatomy

Structure.

Primary Concern of Physiology

Function.

Lung Structure and Function Example

Lungs contain millions of tiny air sacs, giving them a large surface area for exchanging oxygen.

Heart Chamber Arrangement Study

An example of studying anatomy because it focuses on the structure of the heart.

Heart Blood Pumping Study

An example of studying physiology because it focuses on how the heart works.

Anatomy and Physiology Memory Check

A = Anatomy = Arrangement; P = Physiology = Performance.

Levels of Organization Order

Chemical -> Cellular -> Tissue -> Organ -> Organ System -> Organism.

Levels of Organization Memory Trick

C C T O O O ("Cool Cells Team Up Organizing Organisms").

Chemical Level

Atoms and molecules that make up the body.

Cellular Level

Cells, the smallest living units of the body.

Tissue Level

Groups of similar cells working together.

Organ Level

Two or more tissue types working together.

Organ System Level

Multiple organs working together.

Organism Level

The entire living person.

Chemical Level Example

Water molecule.

Cellular Level Example

Muscle cell.

Tissue Level Example

Muscle tissue.

Organ Level Example

Heart.

Organ System Level Example

Cardiovascular system.

Organism Level Example

Human.

Traced Example: Chemical

Proteins.

Traced Example: Cellular

Cardiac muscle cell.

Traced Example: Tissue

Cardiac muscle tissue.

Traced Example: Organ

Heart.

Traced Example: Organ System

Cardiovascular system.

Traced Example: Organism

Human.

Organ vs Tissue Complexity

An organ contains multiple tissue types working together, while a tissue is mainly similar cells.

Organ Systems Interconnection

Cells form tissues, tissues form organs, and organs form systems that work together to keep the organism alive.

Eight Necessary Life Functions List

Maintaining boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, and growth.

Life Functions Memory Idea

Protect -> Move -> Respond -> Eat -> Use -> Remove -> Reproduce -> Grow.

Maintaining Boundaries

Keeping the body's internal environment separate from the outside.

Movement

Moving the body or substances within the body.

Responsiveness

Detecting and reacting to changes.

Digestion

Breaking food into smaller nutrients.

Metabolism

All chemical reactions occurring in the body.

Excretion

Removing waste.

Reproduction

Producing new cells or new organisms.

Growth

Increasing the size or number of cells.

Maintaining Boundaries Example

Skin protects the body.

Movement Example

Walking.

Responsiveness Example

Pulling away from something hot.

Digestion Example

Stomach breaking down food.

Metabolism Example

Cells using glucose for energy.

Excretion Example

Kidneys producing urine.

Reproduction Example

Cells dividing.

Growth Example

Bones growing.

Five Survival Needs List

Nutrients, oxygen, water, normal body temperature, and appropriate atmospheric pressure.

Survival Needs Memory Acronym

NOW Temperature & Pressure (Nutrients, Oxygen, Water, Temperature, Pressure).

Purpose of Nutrients

Provide energy and materials needed for growth and repair.

Purpose of Oxygen

Cells use oxygen to release energy from nutrients.

Importance of Body Temperature

Body reactions and enzymes only work properly within a certain temperature range.

Importance of Atmospheric Pressure

Proper pressure allows normal breathing and oxygen exchange in the lungs.

Importance of Water

Helps chemical reactions, transports substances, regulates temperature, and removes waste.

Life Function vs Survival Need

A life function is something the body does, whereas a survival need is something the body requires.

Standard Anatomical Position

Standing upright, facing forward, arms at the sides, palms facing forward, and feet facing forward.

Anatomical Position: Head and Eyes

Facing forward.

Anatomical Position: Arms

Positioned at the sides.

Anatomical Position: Palms

Facing forward.

Anatomical Position: Legs

Straight or upright.

Anatomical Position: Feet

Facing forward.

Importance of Anatomical Position

Gives everyone a standard reference point for describing body locations.

Superior

Above; toward the head.

Inferior

Below; toward the feet.

Anterior

Toward the front.

Posterior

Toward the back.

Medial

Toward the body's midline.

Lateral

Away from the body's midline.

Intermediate

Between two structures.

Proximal

Closer to the point where a limb attaches.

Distal

Farther from the point where a limb attaches.

Superficial

Closer to the body's surface.

Deep

Farther from the body's surface.

Directional Pair: Superior and Inferior

Up and down.

Directional Pair: Anterior and Posterior

Front and back.

Directional Pair: Medial and Lateral

Middle and side.

Directional Pair: Proximal and Distal

Close and distant.

Directional Pair: Superficial and Deep

Surface and inside.

Nose to Mouth Direction

The nose is superior to the mouth.

Heart to Lungs Direction

The heart is medial to the lungs.

Skin to Muscles Direction

The skin is superficial to the muscles.

Elbow to Wrist Direction

The elbow is proximal to the wrist.

Stomach to Heart Direction

The stomach is inferior to the heart.

Utility of Proximal and Distal

They describe how close or far something is from where the limb attaches to the body.

Body Plane

An imaginary flat surface used to divide the body into sections.

Sagittal Plane

Divides the body into right and left portions.

Midsagittal Plane

Divides the body into equal right and left halves.

Parasagittal Plane

Divides the body into unequal right and left portions.

Frontal (Coronal) Plane

Divides the body into front and back portions.

Transverse (Horizontal) Plane

Divides the body into upper and lower portions.

Right and Left Plane

Sagittal plane.

Anterior and Posterior Plane

Frontal plane.

Superior and Inferior Plane

Transverse plane.

Sagittal Plane Memory Trick

S = Sides (Sagittal -> left/right).

Frontal Plane Memory Trick

F = Front (Frontal -> front/back).

Transverse Plane Memory Trick

T = Top (Transverse -> top/bottom).

Four Abdominopelvic Quadrants

RUQ (Right Upper Quadrant), LUQ (Left Upper Quadrant), RLQ (Right Lower Quadrant), LLQ (Left Lower Quadrant).

Quadrant Right and Left Convention

Right and left refer to the patient's right and left.
