What is tissue in the human body?
A mass of of similar cells that form an organ.
Name two systems the circulatory system work with.
Respiratory system (takes in oxygen from air in your lunds and circulatory systems carries the oxygen to cells in your body0
Digestive system ( the digestive system breaks down food into nutrients and the circulatory system carries the nutrients to the cells)
More than half of our blood is made up of this.
What is red blood cells.
All cells come from other cells?
TRUE
What are the parts of the nervous system?
Brain, spinal cord, nerves
This allows a multi-cellular organism to take in nutrients from the environment and move them throughout the body.
What is a transport system.
What are the 4 parts of blood?
Red blood cells, white blood cells, platelets, plasma
This is the function of white blood cells.
What is to help our immune system fight off infections.
The blood picks up oxygen from the lungs and delivers it to the cells and picks up carbon monoxide from the cells and delivers to the lungs so we can breathe it out.
False (It picks up CARBON DIOXODE)
How are the nervous system and the muscular system related?

This type of cell has a short lifespan.
What is uni-cellular cell

70 % are bones are made of calcium
How does blood move throughout our bodies?
It is pumped throughout the body by the heart.
The heart is the core of the nervous system.
False (The brain is the core of the nervous system.)
The main pathway for messages between the brain and the rest of the body.
What is the spinal cord.
Name one way the unicellular and multi-cellular cells are alike.
made of cells, move, grow, reproduce, gets nutrients, perform all 6 life functions, excretion (gets rid of waste) breathes
What are the building blocks of all living things?
Name 2 functions of the blood in our body.
1. Pick up nutrients from our food and drop it off to the cells that need it
2. pick oxygen from the lungs and drop it off to cells
3. pick up carbon dioxide from the cells and carries it to the lungs so we can breathe it out.
True
How does the nervous system and the digestive system work together?
A part of the nervous system tells the muscles of the digestive systems to move food.
What are the 6 life functions of all living things?
Growth, reproduction, respiration, nutrition, excretion, movement
Name the 6 major systems of the human body.
Digestive, respiratory, muscular, skeletal, cardiovascular, circulatory
What is the function of platelets in our blood?
The platelets are tiny parts of the blood that helps our blood to clot and stop bleeding.
Muscles can have memory?
True - our muscles memorize movements we have done over and over again.
