100

This type of tissue covers and protects body surfaces and organs.

What is epithelial tissue?

100

This organ pumps blood through the body, helping to circulate oxygen and nutrients.

What is the heart?

100

This system regulates body functions through electrical signals and helps respond to stimuli. 

What is the nervous system?

100

Name the two types of digestive mechanisms and give an example for both.

What are chemical (ex, saliva) and mechanical (ex, chewing)?

200

This tissue joins and supports other tissues. Examples include bones and cartilage. 

What is connective tissue?

200

This organ contains air sacs called alveoli which help with gas exchange. 

What are the lungs?

200

This system works with the digestive system to deliver oxygen and nutrients to cells.

What is the circulatory system? 

200

This part of the skeleton includes bones like the skull, spine, and ribs. This skeletal system protects vital organs.

What is the axial skeleton? 

300

This tissue allows for body movement by contracting and relaxing. 

What is muscle tissue?

300

This organ filters waste from the blood and maintains water balance in the body. 

What are the kidneys? 

300

This system eliminates waste and maintains water and salt balance in the body.

What is the excretory system?

300

1) This part of a neuron carries electrical signals away from the cell body.
2) This structure in a neuron receives signals from other cells. 

What is the axon and dendrite?

400

This tissue sends electrical signals throughout the body to control functions. 

What is nervous tissue?

400

This organ absorbs nutrients from food and is lined with tiny villi to increase surface area.

What is the small intestine?

400

This system helps the body maintain internal stability by regulating temperature and nutrient levels.

What is the circulatory system?

400

This fatty tissue stores energy and insulates the body.

What is adipose tissue? 

500

This component is found in connective tissue and provides structural support to the cells. It consists of proteins and polysaccharides and plays a role in allowing tissues to withstand stretching, compressing, and other physical stresses. 

What is the matrix? 

500

This organ is responsible for producing bile, which aids in the digestion of fats and plays a crucial role in detoxifying the blood. It helps regulate blood sugar levels and processes nutrients absorbed from the digestive tract. 

What is the liver?

500

This system is vital in defending the body against disease and maintaining overall health. It consists of vessels, nodes, the spleen, and tonsils and works closely with the circulatory system. It helps maintain homeostasis by filtering out harmful things, producing defense cells, and regulating fluid balance.

What is the lymphatic (or immune) system?

500
This substance surrounds nerve fibers and speeds up the transmission of electrical signals. 

What is myelin?
