Chapter 1
Classification of living things
Taxonomy
The rest of story
Organization of human Body
Kingdom Atoms organism
Phylum Molecules population
Class Organelles community
Order Cells ecosystem
Family Tissues biosphere
Genus organs
Species organs system
Chapter 2: Functions of cellular structure
Eukaryote = true nucleus
Prokaryote = No nucleus
Plasma membrane = outer covering of cell
cytoplasm = everything inside besides nucleus
organelles = cary out functions such as digestion nutrients.
Golgi apparatus = refines packages and ships macromolecule products
Ribosomes= site of protein synthesis
Lysosomes = digests damaged organelles and cellular debris.
Peroxisome= destroys cellular toxic waste.
Mitochondrion = Produces energy for cell.
Chapter 3: Tissues
Epithelial
Sheet of cells that lines or covers various space/surfaces and body cavities.
simple and statiffied
Simple Squamous: Lines blood vessels, air sacs lungs.
Simple Cuboidal: Lines kidneys, Secretes, reabsorbs water/small molecules.
Simple Columnar: Lines most digestives organs, absorbs nutrients/produces mucus.
Stratified Squamous: Outer layer of skin, mouth, vagina. abrasion, infection.
Stratified Cuboidal: Lines ducts sweat glands secretes water.
Stratified Columnar: Mammary glads, larynx, secretes mucus.
Connective tissues
Special connective tissues
Fibrous: Connective tissues
Loose: Surround internal organs, blood vessels.
Dense: Tendons, ligaments
Elastic: Stretches hollow organs
Reticular Lymphoid: internal framework for liver, spleen, tonsils, lymph glands.
Cartilage: Primarily collagen, fibers in ground substance containing water. (Resistance, compression)
Bone: Hard mineral deposits of calcium and phosphate. (Very strong)
Blood: Blood cells, platelets and blood fluid called plasma (Transports materials, helps defense mechanisms).
Adipose tissue: Filled with fat deposits. (Stores energy)
Muscle
Skeletal: Attached to muscle/move bones
Cardiac: Muscle that pumps the heart
Smooth: Stomach lungs, intestines, blood vessels, uterus.
Nervous System
Nervous tissue: Cells generate and trasmite electrical impulses throughout the body. (Neurons).
Cell body = location nucleus
Dendrites = extension from cell body/ receive from other neurons.
Axon = transmits electrical impulses over long distance.
Organ System
Integumentary System: Protects form injury, infection, dehydration. Temp control, receive sensory input.
Skeletal System: Protects, supports. produces blood cells/minerals
Muscular system: Produce movement/resists movement. Generates heat.
Nervous System: Detects external/internal stimuli
rapid responses to stimuli
Endocrine System: provides body with water, nutrients. Liver synthesizes some proteins lipids + inactivates chemicals like: hormones, drugs, poison.
Circulatory System: Transports materials from cells. Control Temp, helps defense against disease/injury.
Lymphatic System: Return excess tissue fluid to circulatory system.
Respiratory System: Exchanges gases (oxygen/carbon dioxide) between air/blood. Production of sound (Voice).
Urinary System: Maintains volume/ composition body fluids. Excretes wastes.
Chapter 4 Skeletal
Parts of long bone:
Epiphysis: spongy bone, red bone marrow.
Diaphysis: Shaft, yellow marrow (fat).
Ligament
Cartilage
Tendons
Joints
Attach bone to bone.
smoother/more flexible.
Attach Bone to muscle.
Fibrous joints are immovable.
Cartilaginous joints are slightly movable allowing some movement.
Synovial joints are freely movable.
