Expert Solution

18a. Homoeostasis is the physiological processes that maintain the internal chemical,physical environment in a stable state

20b.The homoeostatic mechanism of the body functions as follows

The Stimulus or a change occurs in the steady state of the body.
The receptor senses the change in the physiological state of the body.The receptor then sends the information to the control center.
Control center analyses the stimulus recieved and acts to maintain the steady state of the body. The response to the stimulus is send by the control centre into the effector parts as signals.
Once the signal reches the effector organ it acts accordingly to bring the change to normal and thereby maintain a steady state

30f. The goblet cells are the glands that are modified epithelial cells.Their function is to secrete the mucus which is rich in mucin.The name refers to their cup like structure.They come under the category of unicellular EXOCRINE glands

Explain the mechanism of blood pressure homeostasis. Your answer should state the name of the reflex that maintains constant blood pressure and identify all 5 components of the negative feedback loop. Also, describe in detail how the body would compensate for a rise in blood pressure, including the division of the autonomic nervous system stimulated.
