Study Notes

Scientific Method

Sequence: problem identification, question asking, developing a hypothesis, experimentation, data analysis, conclusion

Data Collection Steps

Involves observation, measurement, samples, and organization

Reasoning Types

Deductive reasoning: draws specific conclusions from general principles
Inductive reasoning: formulates general principles from specific facts

Atoms and Molecules

Atoms: smallest unit of an element, essential for forming molecules
Molecules: formed by the chemical bonding of atoms, essential building blocks of cells

Organs and Tissues

Organs: structures made of two or more tissue types working together for specific functions
Four types of tissues: epithelial, connective, muscular, and nervous

Epithelial Tissue

Functions: provides coverings and produces secretions, depends on capillaries for nutrients via diffusion
Types:
- Simple epithelium: single layer, involved in absorption, secretion, filtration
- Stratified epithelium: multiple layers, provides protection
Shapes: squamous, cuboidal, and columnar

Connective Tissue

Forms the framework for tendons, ligaments, bones, blood, and adipose (fat); some lack a blood supply

Types of Muscle Tissue

Skeletal: voluntary movement, attached to bones
Cardiac: involuntary control, found in the heart
Smooth: involuntary control, present in hollow organs (intestines, blood vessels, bladder, uterus)

Nervous Tissue

Comprises the brain, spinal cord, and nerves

Circulatory System

Composed of heart, blood vessels, and blood; functions to circulate oxygen, hormones, and nutrients throughout the body

Digestive System

Extends from mouth to anus, includes organs such as esophagus, stomach, intestines, liver, pancreas; functions to digest and break down food

Small Intestine

Comprised of duodenum, jejunum, ileum; primary site for nutrient absorption

Colon Function

Removes water from waste after nutrient absorption in the small intestine

Liver Function

Produces bile necessary for fat breakdown

Pancreas Function

Delivers enzymes to the small intestine to aid in digestion

Endocrine System

Controls growth and metabolism; consists of glands that secrete hormones into the bloodstream

Endocrine Glands

Includes pineal, pituitary, thalamus, hypothalamus, thyroid, thymus, adrenals

Integumentary System

Composed of skin, mucous membranes, hair, and nails; protects internal tissues from injury, waterproofs the body, and regulates temperature
