Nutrition in human beings
Not only water but a fluid called saliva secreted by salivary gland
If it is to be observed from the elementary Canal it has to be broken into smaller molecules this is done with the help of biological catalysts called enzymes The Saliva amylase that breaks down starch which is complex molecule to give sugar .
The peristaltic movements occur all along the gut is hydrochloric acid a protein digesting enzymes called with him and mucus hydrochloric acid creates an acidic medium which facilitates the action of enzyme pepsin the mucus protects the inner lining of the stomach from the action of the acid under normal conditions the exit of food from the stomach is regulated by spinster muscle which releases it in small amounts into the small intestine
This is the longest part of the alimentary canal which is fitted into compact space because of extensive coiling tinto meat is easier to digest hence carnivorous like tigers have a shorter small intestine
Small intestine is the site of the complete digestion of Carbohydrates proteins and fats
Acidic and has to be made Alkaline for the pancreatic enzymes to act by us from the liver accomplishes this in addition to acting on face fats are present in the intestine in the form of large globules which make it difficult for enzymes to act on them by short break them down into smaller globules increasing the efficiency of enzyme action
Pancreatic juice times like trypsin for digesting proteins and lipase for Breaking Down emulsified fats
When was president in IT finally convert the protein into amino acids Complex carbohydrates into glucose and fatty acids and glycerol
The inner lining of the small intestine has numerous finger like projections called Villi increase the surface area for absorption
The unabsorbed food is sent into large intestine there more wheeler abs of water from this material the rest of the material is removed from the body by the anus the exit of this waste material is regulated by the anal sphincter
Respiration
Diverse organisms use oxygen to breakdown glucose completely into carbon dioxide and water some use other Pathways that do not involve oxygen in all cases the first step is breakdown of glucose a 6 carbon molecule into three carbon molecules called pyruvate this this process takes place in cytoplasm
Pirate maybe converted into ethanol and carbon dioxide later this process takes place in yeast during fermentation
Breakdown of pyruvate using oxygen takes place in mitochondria process breaks of the three carbon pyruvate molecule to give 3 molecules of carbon dioxide .
The other product is water save this process takes place in the presence of air it is called aerobic respiration when there is lack of oxygen in our muscle cells another pathway for The breakdown of pyruvate is Tejas pirate is converted into lactic acid which is also a three carbon molecule this build of lactic acid in our muscles during sudden activity causes cramps
Molecule called ATP which is used to fuel all other activities in the cell. In this process ATP is broken down australiagiving rise to a fixed amount of energy which can drive the endothermic reactions taking place in the cell .
ATP
ATP the energy currency for most cellular processes . The energy released during the process of respiration is used to make and ATP molecules from ADP and inorganic phosphate.
When the terminal for speed link it in ATP is broken using water the energy equivalent to 30.5 kilo joule per mole is released.
ATP can be used in the cell for the contraction of muscles protein synthesized conduction of nerve impulses and many other activities
At night where and when there is no photosynthesis occurring co2 elimination is the major exchange activity going on. Carbon mono oxide generated during respiration is used for photosynthesis hence there is no carbon dioxide released.
In human beings is taken into the body through the nostrils their passing through the nostrils is preserved by 5 years that line the passage the passage is also lined with mucus which helps in this process from here the air passes through the throat into the lungs rings of cartilage are present in the throat this ensure that the air passage does not collapse.
Within the lungs the passage divides into smaller and smaller tubes which finally terminate in balloon like structure which are called alveoli.
Instead respiratory pigments take up oxygen from the air in the lungs and carry it tissues which are deficient in oxygen before releasing it.
In human beings a respiratory pigment is haemoglobin which has a very high affinity for oxygen this pigment present in the red blood .
Transportation
Blood consists of a fluid medium called Plasma in which the cells are suspended plasma transport food and nitrogenous waste in dissolved form.
And have only two chambers to their hearts and the blood is pumped to the gills is oxygenated their and fastest directly to the rest of the
Blood goes only once through the heart in the field doing one cycle of passage to the body on the other hand it goes through the heart twice during each cycle in other vertebrates this is known as double circulation.
Arteries are the vessels which carry blood away from the heart to various organs of the body
Thick elastic walls.
Where is collect the blood from different organs and bring it back to the heart.
The smallest vessels have valves which are one cell thick and are called capillaries. Exchange of material between the blood and surrounding cells explain across this thing was the capillaries then joined together to form veins that convey the blood away from the organ or tissue .
Lymph
Should also involved in transportation this is called lymph tissue fluid.
