Skeletal, Nervous, Integumentary & Muscular
This body system allows voluntary movement of your arms and legs.
What is the muscular system?
This organ is responsible for absorbing most nutrients from digested food.
What is the small intestine?
This organ pumps blood throughout the body.
What is the heart?
This system controls growth, metabolism, and puberty using hormones.
What is the endocrine system?
This organ is commonly used as a model during frog dissection to how study gas exchanges in humans.
What are the lungs?
These attach muscle to bone, allowing movement to occur.
What are tendons?
Stomach acid breaking down food into smaller molecules is an example of this type of change.
What is a chemical change?
These tiny air sacs are surrounded by capillaries and allow gas exchange to occur.
What are alveoli?
This gland is known as the “master gland” because it controls other endocrine glands.
What is the pituitary gland?
One advantage of using a frog as a model is that its organ systems are organized similarly to this organism.
What is a human?
This system both protects vital organs and provides structure that allows muscles to create movement.
What is the skeletal system?
The length and folded structure of the large intestine increases this process in the digestive system.
What is water absorption?
This organ helps move oxygen from the alveoli into the bloodstream.
What are capillaries?
The pancreas plays a role in digestion and also produces this hormone that regulates blood sugar.
What is insulin?
3 disadvantages of using frogs as models when studying human bodies.
What 1)size or complexitity of organs, 2) placement of organs 3)different body processes (function of organs vary)
Damage to these two structures can prevent signals from traveling between the brain and muscles.
What are the nerves and spinal cord?
This body system delivers absorbed nutrients from the small intestine to cells throughout the body.
What is the circulatory system?
This muscle contracts to increase chest cavity volume, allowing air to enter the lungs for oxygen exchange.
What is the diapgragm?
These two systems work together to regulate puberty and reproductive development.
What are the endocrine and reproductive systems?
This hierarchical level of organization consists of multiple organs working together to perform a specific function.
What is an organ system?
An athlete tears a part in their knee. This structure connects bone to bone and its damage affects both joint stability and movement.
What is a ligament?
If the kidneys fail to filter waste from the blood, this system becomes overloaded with toxins.
What is the circulatory system?
During an infection, these cells travel through the bloodstream to identify and attack pathogens.
What are white blood cells?
In a female frog, these structures produce eggs and release them into the body cavity during reproduction.
What are ovaries?
When the lungs cannot properly exchange oxygen, the heart must work harder to pump blood. This explains how two body systems are directly affected when gas exchange fails.
What are the respiratory and circulatory systems?
