Respiration
Glands produce enzymes that are used to break down large molecules into smaller ones that are ready for abortion
...
Major parts of the digestive system
The Oesophagus is made up of a thick muscular wall and is adapted so that food can pass down it easily from the mouth to the stomach
...
The stomach is a muscular sac with an inner layer that produces enzymes
...
There are glands within it that produce enzymes to digest protein
...
The mucus prevents the
stomach being digested by its own enzymes
...
Food is further digested by enzymes in the small intestine
...
The inner walls of the small intestine are folded into villi, giving them a larger surface area
...
The microvilli are found on the epithelial cells
of each villus
...
The large intestine absorbs water
...
Because there is little water within
the large intestine, the food becomes drier, thus forming faeces
...
The salivary glands are positioned near the mouth
...
This secretion will contain the
enzyme amylase
...
Aerobic respiration needs oxygen
...
Note that respiration is different to breathing (ventilation)
...
Blood
Blood transports materials and heat around the body, and helps to protect against disease
...
Hemoglobin enables red blood cells to carry
oxygen from your lungs to all parts of your body and to carry carbon dioxide from other parts of the body to your lungs so that it can be
exhaled
...
All white blood cells are produced and derived from a multipotent cell in the bone
marrow known as a hematopoietic stem cell
...
Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen
...
Anaerobic respiration is in the absence of air
...
Although oxygen is not used as the final electron
acceptor, the process still uses a respiratory electron transport chain; it is respiration without oxygen
