• Inspection
• Looking at the bodies appearance

Feeling a structure with the hands, such as popping a swollen lymph node or taking a pulse

Listening to the natural sounds made by the body

The examiner tap from the body feels for abnormal resistance and listens for signs of abnormalities

Cutting And separation of tissues to revealthe relationship

Dissecting a dead human body

Study of more than one species in order to examine structural similarities

The study of function

the study of structure

Change in the genetic composition of a population of organisms

A single complete individual, the baby

a group of organs with a unique Collective function. example the circulation respiratory or digestive

A structure composed of two or more tissue types at work together to carry out a particular function examples skin pancreas

• Mass of similar cells and cell products that forms a discrete region of an organ and performs a specific function
• 4 classes - epithelial, connective, nervous, and muscular tissue

• Are the smallest units of an organism that carry out all of the basic functions of life.
• Most cells have one nucleus an organelle that contains its Dna

Microscopic doctors in a cell that carry out its individual functions example mitochondria, centrioles, and lysosomes

Composed of two atoms

• Is the sum of all this internal chemical change
• Consists of two classes of reaction anabolism and catabolism

Molecules are synthesized together

• Molecules are broken down into simpler ones
• examples protein digestion

The separation of waste from tissues and their elimination from the body

The ability of organisms to sensr and react to stimuli

• Keeping internal conditions able
• Dynamic equilibrium

• Any change in former function over the lifetime of the organism involves two major processes differentiation changing cells into cells are committed to a particular task
• Growth an increase in size

Passing the genes over

Population changing as a whole their genetics change

• A process which the body senses a change and activates mechanisms or reverses it.
• Example thermo stat
• Vasoconstriction when cold (shivering)
• Vasodilation when hot (sweating)

• 3 components
• Receptor- this is a change in the body
• Integrating center- control center
• Effector- cell organ carries out the action

Producing rapid change example stimulating contractions
