General Knowledge
All of your body systems work together to achieve this, a stable balance of energy, resources, and waste, that helps an organism stay alive.
What is homeostasis?
This is one of the digestive systems three functions, the breaking down of food to extract its nutrients.
What is digestion?
Your skeletal and muscular system are attached to each other, to allow the body to perform this important function.
What is movement?
This is the main muscle of the circulatory system, it pumps blood.
What is the heart?
This organ is the main control center of the nervous system.
What is the brain?
All of our body systems work together. For example, the digestive system is mostly made up of this kind of tissue, the main tissue for our muscular system.
What is muscle tissue?
In the intestines, nutrients are spread to the rest of the body, in this process, which is one of the three main functions of the digestive system.
What is absorption?
The heart is made of this special type of muscle.
What is cardiac muscle?
This is the muscle in the respiratory system that controls air coming in and out! (It is *not* the lungs)
What is the diaphragm?
This is the part of the nervous system that sends out all the messages from the brian.
What is the spinal cord?
One of the main forces our bodies protect us from is this, a force that is always pressing down on us and keeping us attached to the ground.
What is gravity?
A significant amount of chemical digestion occurs in this organ, which produces acid to chemically break down food.
What is the stomach?
This is a type of skeletal tissue that makes up your ears, nose, and the space between joints. Sharks are almost entirely made of this!
Cartilage.
This is the main element brought in by the respiratory system and spread throughout the body by the circulatory system.
What is Oxygen? (O2)
The nervous system is responsible for this, instructing the other body systems on what to do.
What is control?
All of our body systems are made of different types of this, the building block that makes up all of life.
What are cells?
This type of digestion mostly occurs in the mouth, with your jaw and teeth physically breaking down food into smaller pieces.
What is mechanical digestion?
This is the parts of bones that connect to each other to allow for movement.
What are joints?
This is the main element brought back to the lungs by the circulatory system. It is then breathed out and used by plants for photosynthesis.
What is Carbon Dioxide? (CO2)
This is the name for the brain and spinal cord, the main control center of the nervous system.
What is the Central Nervous System?
Our body systems are sustained by macromolecules. Name two of the four we've learned in this class!
What are carbohydrates, lipids, nucleic acids, and proteins.
This is the third function of the digestive system, to remove waste products from the body.
What is elimination?
These are the names of the two parts of your skeleton.
What are the appendicular and axial skeleton?
This is the name of the process where the circulatory system gets or gives oxygen & carbon dioxide. It happens in capillaries.
This is the name for all the nerve cells throughout the body that communicate their needs to the brain.
What is the Peripheral Nervous System?
