Wht is the structure of the heart
What is the main function of the heart
- between lungs in chest, with apex to the left
- Cardiac muscle and epithelial linings.Pumps blood to the lungs and round the body carrying oxygen and nutrients to cells, removing carbon dioxide

Main functions
Duodenum
C-shaped part of the small intestine lying beyond the stomach.
Two coats of non-striated muscle, lined by columnar epithelium.
Passes chyme to ileum and secretes major digestive secretions.
Ileum Name of organ

structure of organ
Main functions
Long coiled part of small intestines joined to duodenum
- two coats of non straited muscle and vili lined by columnar epithelium
- passes undisgestive to colon , absorbs nutrients to blood stream
Colon Name of organ
Location of organ
structure of organ
Main functions
Joins to ileum in right-hand side of the abdomen, runs up to the liver infront of the stomach down the left side to join with the retum
d side of the abdomen, runs up to the liver in front of the stomach and down the left side to join with the rectum.
Two coats of non-striated muscle, but outercoat not complete.
Absorbs water, producing semi-solid faeces.
Kidney
Name of organ

structure of organ
Main functions
One on each side of the back wall of the abdomen below diagraphm Left kidney is higher than the right, due to position of the liver.
Composed of nephrons.
Eliminate waste products and water, maintaining homeostasis.
