Body Systems
This system provides a protective barrier against injury and pathogens and includes the skin.
integumentary system
Bring oxygen into the body and carry it to cells.
respiratory and circulatory
Osteoporosis weakens bones and increases the risk of fractures.
skeletal system
This term describes the body’s process of keeping internal conditions stable.
homeostasis
When the body gets too hot, this process helps cool it as moisture evaporates from the skin.
sweating
This system includes the brain, spinal cord, and nerves, and coordinates the body’s responses.
nervous system
Absorb nutrients and transport them throughout the body.
Asthma affects the airways and can make breathing difficult.
respiratory system
When body temperature rises, sweating helps cool the body. This is an example of this type of feedback loop, which counteracts a change.
negative feedback
This organ pumps blood and works with blood vessels to deliver oxygen and nutrients around the body.
heart <3
This system breaks down food and absorbs nutrients.
digestive system
Regulates our body temperature throughout the day.
(double points if you can name ALL three systems involved)
circulatory, integumentary, and nervous
Coronary artery disease affects blood vessels that supply the heart.
circulatory system
During childbirth, contractions stimulate hormone release that intensifies contractions until birth. This is an example of this type of feedback, which amplifies a change.
positive feedback
When you inhale, this muscle contracts and flattens, increasing the space in your chest so air moves into your lungs.
the diaphragm
This system transports oxygen, nutrients, hormones, and wastes through the body.
circulatory system
Fights off pathogens and forms a physical barrier to block them from entering the body.
integumentary and immune
Crohn's disease causes inflammation in the intestinal lining.
digestive system
When blood glucose rises, the pancreas releases insulin, which helps lower it. This response is an example of this kind of feedback.
negative feedback
Chewing breaks food into smaller pieces without changing its chemical makeup. This is an example of what kind of digestion? (chemical or mechanical)
mechanical digestion
This system produces hormones that regulate processes such as growth and metabolism.
endocrine system
Release of hormones that support the development of an embryo.
endocrine and reproductive
Diabetes can involve problems with insulin, a hormone that helps regulate blood sugar.
endocrine system
During blood clotting, activated platelets release signals that attract and activate more platelets at the injury site. This self-amplifying response is an example of which type of feedback loop?
positive feedback
What organ absorbs the most nutrients in the digestive system?
the small intestine
