Study Notes
Integumentary System
- Forms the external body covering, including skin, hair, and fingernails
- Waterproofs the body
- Acts as a physical barrier to protect the body from invading pathogens and injury
- Produces vitamin D with the help of sunlight
- Excretes salts in perspiration
- Helps regulate body temperature
- Location of cutaneous nerve receptors
Skeletal System
- Consists of bones, cartilages, ligaments, and joints
- Gives the body structural framework
- Provides muscle attachment for movement
- Protects vital organs
- Site of blood cell formation
- Stores minerals
Muscular System
- Consists of skeletal muscles attached to the skeleton
- Produces movement of bones
- Supports and stabilizes certain body structures
- Generates heat for the body (a byproduct of contraction)
Nervous System
- Consists of the brain, spinal cord, nerves, and sensory receptors
- Responds to internal and external stimuli
- Sensory receptors detect changes
- Messages are sent to the central nervous system
- Central nervous system assesses information and activates effectors (muscles and glands)
Endocrine System
- Comprised of many glands that secrete chemical messengers (hormones) into the blood
- Works closely with the Nervous System to regulate and control bodily functions
- Body functions controlled by hormones include growth, reproduction, and use of nutrients
- Endocrine glands include the hypothalamus, pituitary gland, thyroid and parathyroids, adrenal glands, thymus, pancreas, pineal gland, and ovaries (females) and testes (males)
Cardiovascular System
- Includes the heart, blood, and blood vessels
- Heart pumps blood
- Vessels transport blood to tissues
- Pumps and transports blood around the body, containing oxygen, carbon dioxide, nutrients, hormones, and metabolic waste products
Lymphatic System
- Includes lymph, lymphatic vessels, lymph nodes, and lymphoid organs (spleen, thymus, MALT tissue)
- Re-absorbs leaked fluids from the extracellular spaces and returns it back to the bloodstream
- Absorbs lipids and lipid-soluble vitamins directly from the digestive tract
- Plays a huge role in immune function
Respiratory System
- Includes the nasal passages, pharynx, larynx, trachea, bronchi, and lungs
- Gases are exchanged with the blood through air sacs (alveoli) in the lungs
- Supplies the body with necessary oxygen (absorption)
- Removes carbon dioxide (excretion)
Digestive System
- Includes the oral cavity (mouth), esophagus, stomach, small and large intestines, rectum, and accessory organs
- Breaks down and digests food
- Allows for nutrient absorption into blood
- Eliminates indigestible material as feces
Urinary System
- Includes the kidneys, ureters, urinary bladder, and urethra
- Eliminates nitrogenous wastes
- Maintains acid-base balance
- Regulates water and electrolyte balance
- Helps regulate blood pressure
