CARDIOVASCULAR Dsyrhythmias * Etiology * Disturbances in automaticity – initiation of impulse is altered * Disturbances in conduction – alteration in the speed the impulse travels * Reentry of impulses – cardiac tissue is depolarized multiple times by the same impulse * Speed‚ distance and location can be changed or affected (blockages cause change in heart rhythm) * Risk factors * Cardiovascular disease‚ MI * MI – death of tissue – no electricity

early stage of digestion: Tongue — a muscle that is covered by taste buds. It assists the process of chewing and man oeuvres food to a position where it can be swallowed easily. Salivary glands — begin the process of chemical digestion through the secretion of the enzyme‚ salivary amylase. This enzyme begins the process of breaking down carbohydrates. Saliva also moistens food which helps it to be swallowed more easily. Teeth — break food down mechanically into smaller particles that may be ingested

The Reproductive System The female and male reproductive systems share many similarities and many differences. . Each system has different parts‚ problems and care. Each system has different purposes‚ the male reproductive system’s function is to produce sperm‚ while the female reproductive system’s function is to produce ova‚ store ova and house a fertilized egg. The effects of various hormones modulate both. Some of these include gonadotropin-releasing hormone‚ follicle-stimulating hormone‚
