Cells
What is a cell?
A basic unit of life and the smallest part of a living organism.
Name at least 3 parts of the respiratory system.
Nose, mouth, trachea, lungs, diaphragm, nasal passage
The function of the digestive system.
What is to break down food so it can be used by your body.
What is the function of the circulatory system?
The circulatory system carries oxygen, food and wastes throughout the body. (It delivers nutrients throughout our bodies.)
What is the function of the skeletal system?
Gives your body structure and support.
1. provide structure for the body
2.take in nutrients
3. carry out important tasks
What are the lungs?
Name at least 3 parts of the digestive system.
mouth, esophagus, stomach, large intestine, small intestine
What is the function of the heart?
To pump blood through the arteries.
What is the function of the muscular system?
The muscles pull the bones to control the movement in our bodies.
An organism made of many cells
What is multicellular?
This body system works with the respiratory system to bring oxygen into the body and deliver it to the cells.
What is the circulatory system?
How long does food remain in your stomach?
Name the parts of the circulatory system.
heart, blood vessels (veins,arteries, capillaries) and blood
Name the parts of the skeletal system
Tendons, ligaments, cartilage
An organism made of only one cell
What is unicellular?
True or false? The circulatory system is located throughout most of the body.
What is true? (The circulatory and nervous systems are located throughout most of the body.)
Why is each stage in the digestive process important?
Each stage prepares the body for the next stage of digestion.
What are the three types of blood vessels?
arteries, veins, capillaries
What happens when muscles expand and contract?
When muscles expand they become larger and when they contract they become smaller and pulls the bone closer to the body.
Give one example a unicellular organism and one example of a multicellular organism.
Unicellular - (bacteria, ameoba, paramoecium)
Multicellular - (plants, animals, humans)
Fill in the blanks:
When you breathe - ______________ is taken into your body and _________________ is removed from your body.
Oxygen, Carbon dioxide
Name the five stages of the digestive system.
Chewing, swallowing, the stomach, the small intestine, the large intestine
What 2 other systems does the circulatory system work with?
Respiratory (takes in the oxygen that the circulatory system carries throughout the body.
Digestive - (breaks down the food so the circulatory system can absorb and carry the nutrients to the rest of the body)
Explain how the skeletal system and the muscular system work together?
Bones would not work without muscles. Muscles pull the bones to produce movement.
