cells

-Vary in size, shape, and function

-Need food, water, and oxygen to live and function

- Contain three basic structures: cell membrane, nucleus, and the cytoplasm

Tissues

are a group of cells with specialized functions

-Four basic types: Connective, Epithelial, Muscle, and Nerve

Organs

Groups of tissues that work together to perform a specific function

EX: Kidneys: maintain water and salt balance

EX: Stomach: breaks down food

Muscle tissue

is able to contract and expand, allowing the body to move

Connective tissue

The fibrous substance that holds and connects body parts together

EX: bones, ligaments, and tendons

Nerve tissue

tissue that carries messages to and from the brain and spinal cord from all parts of the body

epithelial tissue

covers the internal and external body surfaces.

EX: Skin and internal organs (such as the intestines)

Systems

When a group of organs all work together for a common purpose, a system is formed

integumentary system

consists of the skin and the accessory structures derived from it (hair, nails, sweat glands, and oil glands)

musculoskeletal system

system that supports the body; protects organs; provides body movement; and includes muscles, bones, and cartilage

cardiovascular system

system includes the heart and blood vessels, which pumps and transports blood throughout the body, carrying nutrients to and removing waste from tissues

Respiratory system

body system that includes the lungs and airways and performs breathing

Nervous system

regulates most body activities and sends and receives messages from the sensory organs. This system consists of the brain, spinal cord, and peripheral nerves

urinary system

system that includes the kidneys, ureters, bladder, and urethra. It eliminates metabolic waste, helps to maintain acid-base and water-salt balance, and helps regulate blood pressure

Reproductive system

system that controls reproduction and heredity and is either male or female

Blood system

system includes blood and all its components

lymphatic system

Composed of a network of vessels, ducts, nodes, and organs. Provides defense against infection.

digestive system

the organs that digest and excrete waste

immune system

A system (including the thymus and bone marrow and lymphoid tissues) that protects the body from foreign substances and pathogenic organisms by producing the immune response

endocrine system

system that includes the glands that secrete the hormones that regulate many of the body's activities

sensory system

system covers the eyes and ears and those parts of other systems that are involved in the reactions of the five systems

cell

Groups of these basic elements form

tissue

Tissue that covers the body or its parts is called

epithelial tissue

Body cavities

are the spaces that hold organs

- is divided into the thoracic cavity and the abdominal cavity

thoracic cavity

holds the heart, lungs, and major blood vessels

abdominal cavity

holds the organs of the digestive and urinary systems

Diaphragm

is the muscle that separates the thoracic and abdominal cavities

pelvic

the bottom portion of the abdominal cavity, which contains the reproductive system

vertebral cavity

the spinal and cranial cavities make up the

system that helps eliminate fluids
