Alcohol
may positively affect the cardiovascular system of people over 50 years old by
reducing the risk of clot formation.
<span>Just like with the other body systems, excessive alcohol can have lethal
effects on the cardiovascular system. Chronic alcohol use can upsurge the
workload of the heart which can then lead to arrhythmia's or what is called an irregular
heart beat, inflammation of the heart muscle or myocarditis, weakening of the
heart muscle or cardiomyopathy, increased cholesterol, and even hypertension.
Other problems are prominent with blood clotting and an increased workload of
the heart that is linked to cirrhosis of the liver.</span>
Answer: B. secrete enzymes that kill bacteria
Explanation:
Paneth cells, so-called because they were first described by Dr. Josef Paneth in 1888, are pyramidal cells, with the nucleus in the basal position, and with large granules in the apical position. Its first isolated specific product was the lysozyme, a bactericidal substance, by Alexander Flemming. These cells play an important role in innate immunity in the small intestine, producing a wide diversity of antimicrobial peptides and enzymes such as lysozyme itself, cryptidines, defensins and a lectin with bactericidal properties.
The correct term to fill in the blank would be cortisol. In the context of stress hormones and the brain, cortisol has a profound effect on the hippocampus, a brain structure that plays a pivotal role in memory. Cortisol is classified as a steroid hormone which is produced by the adrenal gland. It is deemed as the stress hormone as it is released as a response to stress as part of the fight or flight process. From studies, cortisol was found to have effect on the hippocampus when present in high levels. It damage and kill the cells in that area of the brain. The hippocampus is the area of the brain that is responsible for the long term memory storage. So, when this part is damage then the storage for our memories would surely be affected.
