Endocrine Vs Nervous System The endocrine system acts with nervous system to coordinate the body’s activities. Both systems enable cells to communicate with others by using chemical messengers. The endocrine system uses chemical messengers called hormones that are transported by the circulatory system (blood). They act on target cells that may be anywhere in the body. The endocrine system is slower than the nervous system because hormones must travel through the circulatory system to reach their target

(BRMs) due to their ability to activate the human innate immune system. Activation of the innate immune system occurs through recognition of β-glucans polymers expressed on cell surfaces of certain pathogens which are known as pathogen-associated molecular patterns (PAMPs). The PAMPs expressed on the cell surface of pathogens bind to complementary receptors called pattern recognition receptors (PRRs)‚ such as Dectin-1‚ which initiates an immune response. Conclusions drawn from investigations aimed

The inflammatory pathology of the nervous system Any of the etiologic agents of infection may give determinations to the nervous system. Usually these are secondary locations of other infections in the body: infectious diseases‚ endocarditis‚ pulmonary and urinary infections‚ regional inflammations etc. The pathways by which pathogens reach the bodies nervous system are: through blood pressure‚ arteries or veins‚ dissemination of nearby (eg the sinuses‚ internal ear‚ etc..) or through neuronal

good for our physical health. It triggers the release of endorphins‚ which is also known as natural painkillers. This helps to produce a general sense of well-being. Laughter also boost our immune system. It decreases stress hormones like cortisol and adrenaline that constrict blood vessels and suppress immune activity. A laugh is also thought of as exercise for the heart and is very often likened to “an internal jogging”. This helps to strengthen our heart and protect us against cardiovascular problems

Lab 28B: Endocrine System Physiology Computer Simulation Introduction The endocrine system is the second greatest control system of the body and has many effects on the tissues and organs. The thyroid gland‚ which is a part of the endocrine system‚ releases a hormone that maintains metabolism. This hormone is thyroxine. Thyroxine production is controlled by thyroid stimulating hormone‚ which is released by the pituitary gland. TSH stimulates the thyroid gland to produce thyroxine. In

Transport System of Organisms Problems faced by Multicellular Organisms: a)Big size-the total surface area to volume (TSA/V) is decreased . Rate of diffusion of substances into and out of all body cells is low. b)Cells are often located far away from the external surface of the body. How multicellular organism overcome these problem? a)Have specialized structure to increase the surface area for the exchange of respiration gases. b)Have transport system to get gases respiration in and

PART A: 1. The main difference between coding outpatient and inpatient is the procedure codes. Current Procedural Terminology (CPT) codes are used for outpatient coding and the International Classification of Diseases Ninth Revision Clinical Modification (ICD-9-CM) is used for inpatient coding. CPT codes are published by the American Medical Association and The World Health Organization (WHO) is responsible for ICD codes. The ICD-9 diagnoses codes are used for both outpatient and inpatient

The human body has eleven main body systems. They are groups of bodily organs coming together to keep the human body going; they can perform one or more functions. The eleven body systems consist of the skeletal system‚ muscular system‚ nervous system‚ circulatory system‚ immune system‚ endocrine system‚ digestive system‚ excretory system‚ respiratory system‚ integumentary system‚ and the reproductive system. The skeletal system is the foundation to the body containing 206 bones and movable and
