Bones are held together by these.
What are ligaments?
This system acts as your transport system, moving materials to and from the cells.
What is the circulatory system?
These are the smallest blood vessels that carry materials to and from individual cells.
What are capillaries?
This organ holds urine until it is ready to pass out of the body.
What is the bladder?
This is the liquid part of the blood. It is straw-colored and contains sugars and dissolved nutrients.
What is plasma?
Muscles are connected to bones with these tough bands of connective tissue.
What are tendons?
This system helps rid our body of waste.
What is the excretory system?
These blood vessels transport blood away from the heart.
What are arteries?
This organ produces urine as it filters waste from our bloodstream.
What is the kidney? (...or "kidneys"-We actually have two.)
This blood component carries oxygen throughout the body.
What are the red blood cells?
The alveoli are tiny air sacs that help gases move between these two systems.
What is the circulatory system and the respiratory system?
These chemical messengers produced by the endocrine system regulate growth and many other bodily processes.
What are hormones?
These blood vessels carry blood back to the heart from all parts of the body.
What are the veins?
This part of the bone produces blood cells.
What is the bone marrow?
These two forms of digestion begin in the mouth.
What is mechanical digestion (breaking food into smaller pieces with teeth, etc.) and chemical digestion (dissolving food with enzymes, acids, etc.)?
Food is pushed down the esophagus by these muscles.
What are involuntary, smooth muscles?
This system helps support our body, protects vital organs, produces blood cells, and stores minerals.
What is the skeletal system?
This part of blood helps form blood clots and stop bleeding when you are injured.
What are platelets?
These joints allow us to move in one direction. Examples include the elbow and knee.
This organ absorbs nutrients into our bloodstream through finger-like projections called villi.
What is the small intestine?
While Stella is running a race, she must move her leg muscles. These muscles must receive more oxygen. To help with this, Stella's blood circulates faster and her breathing rate increases. Name at least 3 systems working together in this example.
Acceptable responses include: nervous system, muscular system, respiratory system, and circulatory system.
This system includes skin, hair, and nails. It acts as a barrier to keep in moisture and keep out harmful invaders.
What is the integumentary system?
This organ helps with digestion by producing bile to break down fatty foods and also filters our blood.
What is the liver?
These joints allow for a wide range of motion and are found in the hip and shoulder.
What are ball-and-socket joints?
These photoreceptors in the eyes can sense colors.
What are cones or cone cells?
Skeletal muscles work in pairs. When one ____________, the other __________________.
What is contracts (gets shorter) and extends (relaxes or gets longer)? Either order is acceptable.
These specialized cells carry messages to and from the brain as part of the nervous system.
What are neurons?
This type of muscles keeps our hearts beating.
What is involuntary, cardiac muscle?
This organ secretes the hormone insulin to regulate blood sugar and also provides enzymes to help with digestion.
What is the pancreas?
These photoreceptors in the eyes detect light and shadow and can see black, white, and gray.
What are rods or rod cells?
