Sporozoa Genus : Plasmodium Species : vivax Habit s and habitat:- Plasmodium is an intracellular sporozoan parasite causing malaria in man. The parasite lives in the RBC’s and liver cells of man and alimentary canal and salivary glands of female Anopheles mosquito. Structure:- Structure of plasmodium is different stages of its life cycle. A fully grown malarial parasite is amoeboid and uninucleated structure known as trophozoite. Trophozoite is surrounded by double layered

Cortisol is produced excessively. The excessive production of cortisol occurs when there is a benign (non-cancerous) tumor is formed at the anterior of the pituitary gland. This leads to the secretion of Adrenocorticotrophic Hormone (ACTH). ACTH is normally produced by the pituitary gland‚ and causes the stimulation of the adrenal glands resulting in the production of cortisol also known as the stress hormone (http://pituitary.ucla.edu/cushings-disease).

FUNCTION 1 Mouth The mouth chews food into smaller pieces preparing it for digestion. Once food hits the mouth the brain prepares the body for digestion procedures. It also initiated the swallowing procedures (Wardlaw‚ Smith (2009). 2 Salivary Gland The salivary gland produces saliva‚ which is used as a solvent‚ making the tongue taste food better. The saliva also contains enzymes that assist in the digestion of certain foods (Wardlaw‚ Smith (2009). 3 Pharynx The pharynx‚ also known as the throat

These features include the lips‚ cheeks‚ roof of the mouth‚ floor of the mouth‚ gums‚ teeth‚ tongue‚ and salivary glands (Human Digestive System). The lips‚ cheeks‚ roof of the mouth‚ and floor of the mouth are primarily used for containment of food. The gums secure the teeth. The teeth are used to cut and grind food. The tongue moves the food around in the mouth‚ and the salivary glands secrete a digestive fluid. Once the mastication process has been completed‚ the food is swallowed and it enters

cells‚ destroying them in the process (C.O.). When it reaches the brain it moves through the efferent nerves (they carry impulses from the CNS) to the salivary‚ glands‚ they cause increased salivation. The virus does that because after that the salvia is the method of transmission into new hosts. After the virus made its way to the salivary glands it continues going through the whole

They are located on cardiac pacemakers‚ on the myocardium‚ in salivary duct glands and in sweat glands. (Adrenergic Receptors‚ 2016). Beta 2 has its primary receptors in the gastro tract‚ urinary bladder‚ bronchial tree and in the skeletal muscle arteries.

and chemical digestion begins. First the food is physically broken down by the mechanical process of mastication (chewing)‚ into smaller particles‚ creating a bolus with the tongue against the soft plate. During this phase‚ the salivary glands mix the food with salivary amylase beginning the chemical digestion of starches. The bolus then enters the pharynx (throat) first then is routed to the esophagus. These two tubes are simply passageways for the food to be carried to the holding tank‚ known
