Objectives ! List all of the major body systems and their
main purpose.
! Identify which major organs make up the body systems.
! Compare and contrast the general anatomical location of major organs (Anatomical Reference Terms.)
Organ Systems ! An Organ System is a series of organs
that work together for a common purpose.
! Each organ system is made up of specific organs and tissues that are specifically designed for the job that they do.
! Each tissue is made up of specialized cells that are unique to that system.
The Major Organ Systems ! There are 10 major
organ systems: ! Skeletal System ! Muscular System ! Integumentary
System ! Circulatory
System BOLD are systems that we
will dissect.
! Respiratory System
! Digestive System ! Excretory System ! Nervous System ! Endocrine System ! Reproductive
System
Skeletal System ! Purpose: To
provide structure for an organism.
! Components: Bones, cartilage and ligaments (connective tissue.)
Muscular System ! Purpose: To
provide movement for the organism as well as for materials within the organism.
! Components: Muscles and tendons (connective tissue.)
Integumentary System ! Purpose: To
provide a barrier to protect the organism from the outside world.
! Components: Skin (the largest organ of the body), hair and nails.
Circulatory System ! Purpose: To act as a
transport service to the cells of the body, delivering oxygen and food.
! Components: Heart, blood, and blood vessels.
! Note: The circulatory system includes the Lymphatic system (body fluid regulation.)
Respiratory System ! Purpose: To
exchange gasses with the circulatory system.
! Components: Lungs, nose, mouth, & diaphragm.
Digestive System ! Purpose: To
physically and chemically break down food for the body’s use.
! Components: Teeth, tongue, esophagus, stomach, liver, gall bladder, small intestine & large intestine (colon).
Excretory System ! Purpose: To rid the
body of waste products produced by body processes.
! Components: Kidneys, bladder, anus, lungs, & skin.
! NOTE: Some organs have multiple functions and can belong to more than one system.
Nervous System ! Purpose: To
communicate and control mental and physical activities and maintain homeostasis.
! Components: Brain, spinal cord, & nerves.
Endocrine System ! Purpose: To
produce and regulate chemical messengers (hormones) in the body.
! Components: Glands, pancreas, ovary, testis & hormones.
Reproductive System ! Purpose: To
produce, store, and distribute gametes.
! Components: Male: Testis, penis, & sperm. Female: Ovary, fallopian tubes, uterus, vagina, eggs.
Objectives ! List all of the major body systems and their
main purpose.
! Identify which major organs make up the body systems.
! Compare and contrast the general anatomical location of major organs (Anatomical Reference Terms.)
