What does the integumentary system do?
Provides protection, regulates temperature, reduces water loss, and produces vitamin D.
What does the skeletal system do?
Provides protection and support, allows body movements, produces blood cells, and stores minerals and fat.
What does the muscular system do?
Produces body movements, maintains posture, and produces body heat.
What does the lymphatic system do?
Removes foreign substances from the blood and lymph, combats disease, maintains tissue fluid balance, and transports fats from the digestive tract.
What does the respiratory system do?
Exchanges oxygen and carbon dioxide between the blood and air and regulates blood pH.
What does the digestive system do?
Performs the mechanical and chemical processes of digestion, absorption of nutrients, and elimination of wastes.
What does the nervous system do?
A major regulatory system that detects sensations and controls movements, physiologic processes, and intellectual functions.
What does the endocrine system do?
A major regulatory system that influences metabolism, growth, reproduction, and many other functions.
What does the cardiovascular system do?
Transports nutrients, waste products, gases, and hormones throughout the body. Plays a role in the immune response and the regulation of body temperature.
What does the urinary system do?
Removes waste products from the blood and regulates blood pH, ion balance, and water balance.
What does the female reproductive system do?
Produces milk, hormones that influence sexual functions and behaviors, and ooxytes and is the site of fertilization and fetal development.
What does the male reproductive system do?
Produces and transfers sperm cells to the female and produces hormones that influence sexual functions and behaviors.
What does the integumentary system consist of?
Skin, hair, nails, sweat glands
What does the skeletal system consist of?
Bones, cartilage, ligaments, and joints
What does the muscular system consist of?
Muscles and tendons
What does the lymphatic system consist of?
Lymph nodes, lymphatic vessels, and lymphatic organs (spleen, thymus, tonsils)
What does the respiratory system consist of?
Lungs and respiratory passages (pharynx, larynx, trachea, bronchi)
What does the digestive system consist of?
Mouth, esophagus, stomach, intestines, and accessory organs (liver, gallbladder, appendix)
What does the nervous system consist of?
Brain, spinal cord, nerves, and sensory receptors
What does the endocrine system consist of?
Glands that secrete hormones (hypothalamus, pituitary, thyroid, thymus, adrenal, pancreas, ovaries, testes)
What does the cardiovascular system consist of?
Heart, blood vessels, blood
What does the urinary system consist of?
Bladder, kidneys, urinary ducts (ureter, urethra)
What does the female reproductive system consist of?
Vagina, uterus, mammary glands, ovaries, and associated structures
What does the male reproductive system consist of?
Penis, testes, ducts, prostate gland, and accessory structures
An organism’s ability to sense changes both internally and externally and adjust to that change.
When cells increase in size or number
The changes an organism goes through from conception to death.
A change in cell structure and function from generalized to specialized.
The change in the shape of tissues, organs, and the entire organism.
The formation of new cells or new organisms.
A relatively constant environment within the body.
Volume, temperature, and chemical content.
The ideal normal value.
A slight increase and decrease of variables.
Maintains homeostasis. Provides a counter-reaction to bring the body back to homeostasis.
Does not maintain homeostasis. Provides a reaction to make the deviation greater creating a cycle that leads away from homeostasis.
Monitors the value of a variable.
Receives information about the variable from the receptor.
Produces responses that change the value of the variable.
