Period 2 – Human Body Systems
Name: Lymphatic: (immune)
Function: transports lymphatic fluids carrying antibodies, proteins, and white blood cells through the
body. Drains extra fluids from tissues. Attacks invaders and fights infection.
Parts: nodes , lymphatic ducts, spleen,
Secondary Systems:
Urinary – filter fluids from blood and effects fluid levels in lymphatic vessels.
Digestive system – liver filters out dead blood cells (including white blood cells)
Cardiovascular – pumps fluids with proteins through the body and exchanges these fluids with
lymph vessels.
Skeletal - produce white blood cells that are carried in the lymphatic system to attack invaders
Name: Digestive:
Function: To take in and break down food so chemical bonds can be put into the blood to provide
energy and materials for growth and repair.
Parts: mouth, liver, esophagus, stomach, large and small intestines, pancreas, gallbladder
Secondary System:
Lymphatic – absorb fatty acids from the digestive system
Endocrine – Pancreas is part of both systems producing insulin to control blood sugar levels
Cardiovascular – transport all the nutrients and fluids taken in
Urinary – extract excess water and ions from the blood
Skeletal – bones protects the digestive system organs and use calcium to grow
Name: Respiratory
Function: Gas exchange to produce energy. You take in oxygen and release carbon dioxide
Parts: Lungs, nose, mouth, bronchi, alveioli,
Secondary System:
Skeletal – jaw opens to allow airflow, ribs protect lungs
Nervous – needs oxygen to provide energy to work.
Endocrine – produces adrenaline that will affect breathing rate
Cardiovascular – bring in air to be transported by blood.
Muscular – diaphragm contracts to allow for lungs to take in oxygen to the lungs
Name: Muscular
Function: movement, maintain posture, body heat production, store minerals such as calcium. Three
types of muscles – smooth, skeletal, cardiac
Parts: biceps brachii, quadriceps, hamstrings
Secondary system:
Endocrine system – bone growth is regulated by hormones
Respiratory – diaphragm is a muscle that controls breathing
Skeletal – provides bones something to pull against to produce movement
Cardiovascular – heart is a muscle and arteries have smooth muscles in their walls
Reproductive – uterus is a large muscle involved in birth
Urinary – bladder has sphincter muscles that control the release of urine.
Name: Reproductive
Function: sexual reproduction to produce genetic diversity
Parts: seminal vesicles, vas deferens, penis, fallopian tube, vagina, uterus, prostate gland, and ovaries
Secondary Systems
Endocrine – produce hormones that control the reproductive system
Skeletal – pelvic bones support baby during pregnancy
Cardiovascular – provide blood to a developing baby through vessels in the placenta
Muscular – uterus is a muscle involved in birth
Digestive – muscles along the digestive tract push food through.
Respiratory – takes in oxygen to provide energy to father, mother and developing baby
Name: Cardiovascular System
Function: Transports nutrients, oxygen, and hormones to the cells of the body and removes carbon
dioxide from the body Parts: heart, arteries, veins, capillaries, pulmonary artery,
Secondary System:
Digestive – absorbs nutrients into the blood
Endocrine – produces hormones into the blood stream, transported to the body
Reproductive – transport, oxygen, nutrients, and hormones to the reproductive
Respiratory – extracts oxygen from air and deposits it into the blood
Skeletal – ribs protect the heart and bone marrow produces blood cells.
Urinary – transports extra water and ions out of the body
Name: Urinary
Function: gets rid of liquid waste in the body regulates ion con
Parts: kidneys, bladder, urethra, ureters
Secondary Systems:
Digestive: also waste removal, takes in the
Cardiovascular: trans
Reproductive: male urethra is part of both systems
Nervous: messages sent to brain when bladder is full
Lymphatic : lymph
Name: Skeletal System
Function: support, movement, stores calcium, produce blood cells
Parts: femur, patella, femur, tibia,
Secondary:
Cardiovascular – bone marrow makes blood
Respiratory – protect the lungs
Endocrine – hormones regulate bone growth
Digestive – provides structure to hold organs in place, extracts calcium to build strong bones
Nervous – skull and vertebral column protects the brain
Muscular – attach to bones and produce movement
Name: Nervous
Function: sends electrical signals throughout the body
Parts: Brain, spinal cord, nerves
Secondary System:
Respiratory system – tells the body to breathe
Digestive system – nervous system tells muscles to contract and move food through system
Cardiovascular – heart gets info from brain,
Endocrine – adrenaline is produced when scared, chemical messaging system.
Skeletal – protect the brain and spinal cord, bones have nerves
Urinary – bladder is full the nervous system tells the body to release.
Name: Endocrine System
Function: Collection of glands that produce hormones that regulate growth, reproduction, metabolism,
sleep and mood
Parts: Hypothalamus, adrenal, thalamus, testes, ovaries
Secondary System
Digestive – food is broken down based on your metabolism, regulates hunger
Reproductive – hormones control development, share the testes and ovaries
Skeletal – growth hormone regulates bone growth, protects glands
Urinary – adrenal gland is located on top of the kidney, regulates ions that are used by nerves
to pass the message.
Cardiovascular – distribute the hormones throughout the body
Nervous - sends signals to release hormone, also a messaging system.
