Human Body Into

Cytoogy

Study of Cells

Histology

Study of tissue

Regional Anatomy

interrelationships of all the structures in specific body region

Systemic Anatomy

Structures that make up discrete body system. Structures that work together to perform unique function

6 Levels of Organization to the Human Body

Chemical, Cellular, Tissue, Organ, Organ System, Organism

Chemical (6 Levels of Organization)

Atoms bond to form molecules with three dimensional structues

Cellular (6 Levels of Organization)

Molecules combine to form fluid and organelles of cells

Tissue (6 Levels of Organization)

Community of similar cells to form tissue

Organ (6 Levels of Organization)

2 or more tissues combine to form an organ

Organ System (6 Levels of Organization)

2 or more organ work to perform body systems

Organism (6 Levels of Organization)

Many organ system work together to perform the functions of an independent organism.

Integumentary System

Hair, Skin, Nails.

Function: Encloses internal body structures. Site of many sensory receptors.

Skeletal System

Cartilage, Bones, Joints.

Function: Supports the body, enable movement with muscular system.

Muscular System

Skeletal muscles, tendons.

Function: Enables movement with skeletal system. Helps maintain body temp.

Nervous System

Brain, Spinal Cord, Peripheral Nerves.

Function: Detects and processes sensory info, activates bodily responses.

Endocrine System

Pituitary gland, thyroid gland, pancreas, adrenal glands, testes, ovaries.

Function: Secretes hormones, regulates bodily processes.

Cardiovascular System

Heart and blood vessels.

Function: Delivers oxygen and nutrients to tissue, equalizes temp in body.

Lymphatic System

Thymus, Lymph nodes, Spleen, Lymphatic vessels.

Function: Returns fluid to blood, defense again pathogens.

Respiratory System

Nasal Passage, Trachea, Lungs.

Function: Removes carbon dioxide from the body, delivers oxygen to the blood.

Digestive System

Stomach, liver, gall bladder, large and small intestine.

Function: Process food for use by the body. Removes wastes from undigested foo.

Urinary System

Kidneys, Urinary bladder

Function: controls water balance in the body. Removes wastes from blood and excretes them.

Male Reproductive System

Epididymis, Testes.

Function: produce sex hormones and gametes. Deliver gametes to female.

Female Reproductive System

Produces sex hormones and gametes. Supports embryo/fetus until birth. Produces milk.

List 11 Organ Systems

Integumentary, Skeletal. Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, Male Reproductive System, Female Reproductive System.
