Cells of the body are organized into four fundamental tissues; epithelial‚ connective‚ muscle and nerve. Epithelial tissues line all surfaces of the body: the skin‚ cavities‚ ducts‚ vessels. They are named according to the cell shape on the free surface. Cells of a tissue are held together by the basement membrane and intercellular fibbers. These tissues receive their nutrition by diffusion‚ for they are without blood vessels. Simple squamous epithelium lines all blood and lymphatic vessel‚ including

An introduction to enzymes Enzymes are the foundation of energy and the life force in all living things. They are responsible for building‚ detoxifying‚ and healing the body. They are also the force that allows your body to digest and absorb food. Enzymes also regulate tens of thousands of other biochemical functions that take place in the body every day. Without enzymes‚ seeds would not sprout‚ fruit would not ripen‚ leaves would not change color‚ and life would not exist. Therefore‚ the study

Homeostasis is the control of internal conditions‚ be it temperature‚ specific blood conditions or other variables within living organisms‚ the purpose of homeostasis is to provide a consistent internal environment for set processes to occur. The endocrine system is made up of glands that produce hormones and release them into the blood‚ they cause certain reactions to occur in specific tissues. The endocrine system affects a large number of the body’s functions‚ including‚ metabolism‚ sexual function

Endocrine system or endocrine disruptor is not something we commonly hear or discuss about in our society. However‚ they both play a big role in humans. Many people have no insight of endocrine system or endocrine disruptor. The endocrine system is glands secreting different types of hormones that go directly into bloodstream to transfer information and instruction to one set of cells to another certain cells. Hormones are the body’s chemical messenger which regulates growth and development‚ body’s

Digestion define as a process where foods been breaking down by enzymatic action in the Gastrointestinal tract (GI tract) into nutrients in preparation for absorption. GI tract is the flexible muscular tube from mouth to anus. The digestion of carbohydrates begin in the mouth‚ where an enzyme‚ salivary amylase (α-amylase;ptyalin) starts to breaking the polysaccharides (starch) into short polysaccharides (dextrin). Dextrin is a partial degradation of starch‚ shorter chains of maltose units. Salivary

The first half of module seven discussed protein digestion‚ absorption‚ and metabolism; while the second half focused on pathological stress and kidney disease. Protein digestion occurs in the stomach and small intestine. When a protein reaches the stomach it is denatured by hydrochloric acid. Once the protein is digested pepsin breaks apart the denatured protein into peptides. Peptides move into the small intestine where they encounter an enzyme that digest the peptides into di- or tripeptides‚

During protein digestion‚ a water molecule is added which breaks down the carbonyl-carbon-nitrogen sin the peptide bonds of proteins causing the liberation of amino acids. This process is referred to as proteolysis. Water molecules break down the carbonyl-carbon-nitrogen single bond (peptide bond) that holds single amino acid molecules together (Caroline Ritchie‚ 2013. This process is called hydrolysis and is catalysed by protease. The three main protease enzymes produced during digestion are pepsin
