Takes in food, breaks it down to molecule size and absorbed nutrients and excrete wastes
What is the function of blood?
A type of connective tissue that circulates through All parts of the body and is the fluid carrying medium
What is the function of the Brain?
The brain cells volunteering involuntary signals throughout the body for daily functions and movements.

What muscle moves through the digestive system
Smooth muscle tissue moves food through the digestive system
Name the system that enables structure
The musculoskeletal system
Name what the musculoskeletal system enables
The movement Of the body
What system is responsible for transporting nutrients throughout the body
The circulatory system in the main organ is the heart
What is the difference between embryonic cells and stem cells?
Embryonic cells come from embroys cells, and stem cells come from adult cells
How can some cells help cure bone diseases
The bone marrow from the stem cells can be used to repair non-functioning bone marrow
What does regeneration mean
To grow new cells to replace damage or loss body parts
What is transplantation
It is the chance for a living tissues or organs from one person to another

What are the functions of the red blood cells
They contain a protein called haemoglobin, which causes oxygen and carbon dioxide to stick to the RbC’s
What is the function of white blood cells
They destroy invading bacteria and viruses, they have a nucleus and can we reproduce themselves
What is the function of plasma
It is a food portion of the blood, and allows red blood cells and white blood cells and platelets the flow to All parts of the body
What is a cardiac muscle tissue
It is a smooth muscle that contracts all at once for a powerful pump
What is a nerve bundle
Nerve bundle is something that regulates heart beats this part of the automatic nervous system which allows the heart of the beat without you having to think or command it
What is a epithelial tissue
It lined out the outside and inside cells of the heart and that is to reduce friction in the movement going on and helps blood flow
What are blood vessels
They are the pathways of the blood which carry nutrients and goes to and from body cells.
What are arteries
They carry blood away from the heart, they are thick walled. And have smooth muscles tissues so they work without thinking about it
What is aorta?
It is a very large artery leading out of the heart
What are arterioles
They are smalls, branching arteries
What are capillaries
They are gas exchange sites where the blood vessels meet the cell. By diffusion
