Digestive + Endocrine System
What is the main function of the respiratory system?
The exchange of oxygen and carbon dioxide between the blood and the cells of the body
Regulation of pH and fluid balance helps maintain this overall condition.
What is homeostasis?
The body system that coordinates the body's actions and transmits signals to and from different parts of the body.
The nervous system
Bodies transform glucose as this molecule for longterm storage.
What is the glycogen?
This chemical is exhaled by animals, but plants "breathe" it in and use it to produce oxygen.
What is Carbon Dioxide?
The central nervous system is composed of the brain as well as this long structure that extends down the back and is the connector between the brain and all other parts of the body.
What is the spinal cord?
This nitrogen-containing waste is removed from the blood.
What is urea?
Define homeostasis
Maintaining a stable or healthy environment inside the body
These chemical messengers travel through the bloodstream to target cells.
What are hormones?
What are the 2 main functions of the circulatory system?
1. Transports oxygen to cells
2. Removes carbon dioxide from cells
These proteins bind specifically to pathogens to mark them for destruction.
What are antibodies?
This connective tissue attaches muscle to bone.
What is a tendon?
The body system that is responsible for breaking down your food into usable nutrients.
The digestive system
This hormone causes cells to absorb glucose from your blood.
What is insulin?
This process allows oxygen to move from the lungs into the blood without using energy.
What is diffusion?
Immune cells communicate using these signaling molecules.
What is an cytokines?
This process removes nitrogen waste from the blood.
What is filtration?
What is the relationship between the respiratory system and the circulatory system?
The respiratory system exchanges oxygen and carbon dioxide with the circulatory system.
This process maintains proper water balance in the body.
What is osmoregulation?
List the levels of organization in the human body from simplest to most complex, starting with the cell and ending with organism.
cell --> tissue --> organ --> organ system --> organism
