Worked Solution & Example Answer:Answer the following questions in relation to systems of response to stimuli in the human body - Leaving Cert Biology - Question c - 2005
Step 1
Explain the underlined terms.
Answer
The pancreas serves dual functions as both an exocrine gland and an endocrine gland. An exocrine gland is defined as a gland that releases its secretions through ducts to a particular site, such as those that produce digestive enzymes which are secreted into the small intestine. Conversely, an endocrine gland releases hormones directly into the bloodstream without the use of ducts, facilitating the regulation of various physiological processes throughout the body.
Step 2
Name a product of the endocrine portion of the pancreas and state one of its functions.
Answer
A primary product of the endocrine portion of the pancreas is insulin. Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose by cells, thereby lowering blood sugar concentrations after meals.
Step 3
Name a disorder other than cancer for each of the following and indicate a possible cause and a means of treatment: 1. Musculoskeletal system
Answer
One disorder of the musculoskeletal system is arthritis. A possible cause of arthritis could be injury or a hormonal imbalance. Treatment options include the use of anti-inflammatory drugs or analgesics, along with rest and exercise to manage symptoms.
Step 4
Name a disorder other than cancer for each of the following and indicate a possible cause and a means of treatment: 2. Nervous system
Answer
A disorder of the nervous system is Parkinson's disease. The potential cause may include genetic factors and a lack of dopamine in the brain. Treatment can involve therapies such as physiotherapy, medications to boost neurotransmitter production, or in some cases, surgical interventions like implants.
