Endocrine Gland = is a ductless gland that releases its secretions directly into the bloodstream Exocrine realeses into ducts 2.sweat tastes salty because it contains dissolved body salts and minerals known as electrolytes. 3.Fingernails are a modification of the epidermis. 4. The dermis is a strong‚ flexible connective tissue layer. Which of the following cell types are likely to be found in the dermis? fibroblasts‚ macrophages‚ and mast cells 5. Keratinocytes

nerves‚ and other pulp structures to enter the pulp cavity of the tooth. Salivary Glands * Three pairs of salivary glands empty their secretions into the mouth. Parotid glands- lie anterior to the ears. Mumps- a common childhood disease‚ is an inflammation of the parotid glands. * Submandibular glands and Sublingual glands empty their secretion into the floor of the mouth through tiny ducts. * Saliva is a mixture of mucus and serous fluids. The mucus moistens and helps to bind

The filtrate flows from the Bowman’s capsule into the renal tubule called the proximal convoluted tubule then into the loop of Henle‚ and finally into the distal convoluted tubule: a. Proximal Convoluted Tubule b. Loop of Henle c. Distal Convoluted Tubule 4. When the radius of the afferent arteriole was decreased‚ the pressure and the filtration rate both decreased

temperature‚ and androgens and estrogens. Some factors that decrease the release of GH include; carbohydrate-rich diet‚ obesity‚ free fatty acids‚ and increased serum glucose level (Adams and Koch‚ 2009). Thyroid-stimulating hormone (TH) controls the secretion of thyroid hormones and targets the thyroid gland. TH is a peptide hormone. Thyroid hormone is produced in the thyroid. It is stimulated by the thyroid-stimulating hormone from the thyroid gland and inhibition occurs when there is negative feedback

Ancillary drugs used in surgery Ancillary drugs are drugs that are used in conjunction with general anaesthetics. Although termed as ancillary drugs‚ these drugs play an integral role in every surgical operation. Ancillary drugs serve multiple functions in surgery and can enhance the surgical procedure and patient safety. To most patients‚ the prospect of an impending surgical operation leads to preoperative anxiety‚ especially given that the outcome of the surgery is unpredictable (Valenzuela

function of the nephron? Filtration of blood and the reabsorption of secreted materials What does the capsule do?It supports and protects the kidney What is the function of the cortex? It is the main sight for filtration‚ reabsorption‚ and secretion What are renal pyramids? Triangular shaped units in the medulla that house the loops of Henle and collecting ducts of the nephron. This is also the site for the counter-current system that concentrates salt and conserves water and urea Where

reticulum is to synthesize lipids in the cell. The smooth ER is also helpful in the detoxification of harmful substances in the cell. Golgi complex- It is organelle in the cell that is responsible for modifying and sorting proteins into vesicles for secretion or transport. These vesicles then deliver the proteins to other cell organelles and to the plasma membrane for cell

protein-digesting enzyme‚ mucus‚ and strong acid” (Reece‚ Taylor‚ Simon‚ & Dickey‚ 2012‚ p. 436) The result of this process occurring in the stomach produces a thick acidic liquid called chyme‚ which is the partially digested food and the digestive secretions. Peristaltic waves will continue to push the chyme toward the small intestine. The small intestine has two major functions; to break down food into smaller molecules and to absorb these molecules into the blood

skull and vertebral column‚ which protect the central nervous system- few pathogens are able to penetrate bone. The skin also is a major anatomical barrier to microorganisms. The surface layer of dead‚ hardened cells is relatively dry‚ and skin secretions make the surface somewhat acidic. When sweat evaporates‚ salt is left behind on the skin. All of these conditions (low moisture‚ low pH‚ and high salinity) prevent most microorganisms from growing and multiplying on the skin. The major medical challenge

One of the ways to downregulate VEGF secretion is by downregulating the cellular sources of VEGF. In other words‚ we can downregulate VEGF at its source by downregulating immune cells‚ such as macrophages via immunosuppressant such as dexamethasone (DEX)‚ a glucocorticoid. Glucocorticoids‚ a
