Q
Integumentary System
A
- Forms external body covering
- Protects deeper tissues from
injury - Temperature regulation
- Synthesizes vitamin D
- Site of cutaneous receptors
– (Pain, pressure, etc.) and sweat and oil glands
3
Q
Skeletal System
A
- Protects and supports body organs
- Provides a framework for muscles
- Blood cells formed within bones
- Stores minerals
4
Q
Muscular System
A
- Allows manipulation of the environment
- Locomotion
- Facial expression
- Maintains posture
- Produces heat
5
Q
Nervous System
A
- Fast-acting control system
- Responds to internal and external changes
- Activates muscles and glands
6
Q
Endocrine System
A
- Glands secrete hormones that regulate:
– Growth
– Reproduction – Nutrient use
– Maintain temperature, day/night cycles, calcium, blood pressure, blood glucose, heart rate, breathing, etc.
7
Q
Cardiovascular System
A
- Blood vessels transport blood
– Blood carries oxygen and
carbon dioxide
– It also carries nutrients and wastes - Heart pumps blood through blood vessels
8
Q
Lymphatic System / Immunity
A
- Picks up fluid leaked from blood vessels
- Returns fluid to blood
- Disposes of debris in the
lymphatic system - Houses white blood cells (lymphocytes)
- Mounts attack against foreign substances in the body
9
Q
Respiratory System
A
- Keeps blood supplied with oxygen
- Removes carbon dioxide
- Gas exchange occurs through walls of air sacs in the lungs
- Produce vocal sounds
10
Q
Digestive System
A
- Breaks down food into absorbable units
- Indigestible foodstuffs eliminated as feces
11
Q
Urinary System
A
- Eliminates nitrogenous wastes
- Regulates water, electrolyte, and acid-base balance of the blood
12
Q
Reproductive System
A
- Produce offspring
- Produce gametes (sperm and eggs)
- Produce sex hormones
- Female structures serve as sites for fertilization and development of the fetus
- Male ducts and glands aid in the delivery of sperm to the female reproductive tract
- Mammary glands produce milk
