Circulatory System• Carries substances through
the body: oxygen, nutrients, hormones, wastes, and water.
Roll: Go To: Connection:
1 or 2 Respiratory System
O2 is absorbed and CO2 is released as waste as blood passes through the lungs.
3 or 4 Immune System
White blood cells of the immune system are transported to infection sites via the circulatory system.
5 or 6 Excretory System
Wastes produced in cells throughout the body and transported to the excretory system via the circulatory system.
Digestive System• Breaks down food for
nutrient absorption into the bloodstream.
• Water absorption takes place in the large intestine.
Roll: Go To: Connection:
1 or 2 Excretory System
Solid wastes left over after digestion are eliminated through the large intestine.
3 or 4 Circulatory System
Nutrients broken down in the small intestine are absorbed as blood passes through and transported to the rest of the body.
5 or 6 Muscular System
Smooth muscled lining the entire digestive tract work together to push food items through the system.
Integumentary System• Hair, skin and nails• Best defense to
keep bacteria from entering your body
Roll: Go To: Connection:
1 or 2 Muscular System
Arrector pili muscles in the skin cause hairs to stand on end.
3 or 4 Circulatory System
Increased blood flow to the skin is used to promote sweating and cooling, while blood flow is reduced when the body needs to conserve heat.
5 or 6 Respiratory System
While not found in mammals, many types of amphibians, some fish and some reptiles are able to breath through their skin surface.
Muscular System• Skeletal- for movement of
limbs• Smooth- helps move stuff
through body• Cardiac- heartRoll: Go To: Connection:
1 or 2 Excretory System
Muscles surrounding bladder wall and sphincter muscles control flow of liquid wastes.
3 or 4 Circulatory System
Cardiac muscle and smooth muscles surrounding the arteries control flow of blood throughout the body.
5 or 6 Nervous System
Triggering a specific sensory nerve causes a rapid muscle contraction known as a reflex arc. example: knee jerk
Respiratory System• Exchange of gases
between body and environment
• Ends at the lungsRoll: Go To: Connection:
1 or 2 Endocrine System
Production of adrenaline causes rapid breathing to increase oxygen flow to the muscles.
3 or 4 Muscular System
Diaphragm and muscles of the ribs act to expand and contract the lungs.
5 or 6 Digestive System
Food traveling down the esophagus is blocked from entering the respiratory system by a structure called the epiglottis, when this malfunctions, choking can result!
Reproductive System• Sperm and egg
come together to produce offspring
Roll: Go To: Connection:
1 or 2 Endocrine System
Hormones like estrogen and testosterone control development of reproductive organs, reproductive cycles and the progress of contractions during labor.
3 or 4 Nervous System
ASK YOU PARENTS
5 or 6 Immune System
The mother’s immune system acts to protect the baby during pregnancy, even after birth, immunity to diseases is continued through the mother’s milk.
Immune System• Protects our body
from infectionsRoll: Go To: Connection:
1 or 2 Integumentary System
Your skin acts as a barrier from pathogens while also secreting acids that destroy most pathogens on contact.
3 or 4 Excretory System
Destroyed pathogens and dead immune cells are removed from the body via the excretory system.
5 or 6 Respiratory System
Mucus produced in the sinuses and nasal passages act to trap dirt and pathogens that enter the body when you inhale.
Endocrine System• Glands that produce
hormones- chemical messages sent through the blood
Roll: Go To: Connection:
1 or 2 Circulatory System
Carries hormones produced by the endocrine system to the locations where they are needed.
3 or 4 Digestive System
Hormones of the endocrine system regulate your metabolism and signal when you are hungry.
5 or 6 Skeletal System
Human Growth Hormone (HGH) signals the body and skeletal system to begin growing during each major growth spurt.
Nervous System• Controls everything in the
body• Carries messages through
the nervesRoll: Go To: Connection:
1 or 2 Muscular System
Electrical signals produced by the nervous system control the contraction of muscles throughout the body.
3 or 4 Endocrine System
The brain acts to control the timing and amount of hormones released to the body.
5 or 6 Integumentary System
Nerve endings imbedded in the skin provide the sense of touch and pain signals that warn of harm.
Skeletal System• The framework that
gives our body structure and support.
• Where blood is produced
Roll: Go To: Connection:
1 or 2 Muscular System
Muscles attached to the skeleton act as levers and pulleys to move the body.
3 or 4 Circulatory System
New red blood cells are produced by special cells in the bone marrow.
5 or 6 Immune System
The white blood cells necessary for locating and destroying pathogens in the body are first produced in the bone marrow.
Excretory System• Elimination of wastes
produced by cells throughout the body.
Roll: Go To: Connection:
1 or 2 Respiratory System
Waste CO2 produced in cells during cellular respiration, is carried to the lungs and exhaled.
3 or 4 Nervous System
Pain signals from the brain indicate the need to eliminate liquid and solid wastes.
5 or 6 Integumentary System
Small amounts of urea are excreted through the skin as salts.
