Endocrine system

An example of Maintenance of homeostasis in humans is the action of glucagon and insulin in regulating the

Concentration of blood sugar

After a hormone enters the bloodstream, it is transported throughout the body, but the hormone affects only certain cells. only certain cells are affected because the membranes of these cells have what specific structure?

Receptors

The failure of a cell to react in a normal manner to insulin is most likely the result of a problem with

Receptors

Pituitary growth hormone can affect cells in various parts of the human body because the hormone is secreted directly into

The bloodstream

The secretion of hormones from gland F is regulated by hormones secreted from gland

A

Which gland secretes a hormone that stimulates the development of egg cells in ovaries and influences the secretion of other hormones involved in human reproduction?

A

What will most likely result if a diabetic injects an overdose of insulin?

A dangerous drop in blood sugar levels

An increase in the level of insulin in the blood would most directly result in

A decrease in the amount of glucose in the blood

In a certain community a number of humans have an abnormally enlarged structure under the skin of the lower front side of their necks. The cause of this conditions is most likely

A lack of iodine in the diet, which has caused the development of a goiter

Which gland could become enlarged due to lack of iodine in the diet?

B

Which gland produces parathormone, which regulates the metabolism of calcium?

C

Which structure contains specialized cells that secrete the hormones insulin and glucagon?

D

The level of glucose in the blood is regulated by secretions from glands

D and E

Which pair of terms is most closely associated with the human endocrine system?

Ductless glands and Hormones

The hormone that is important to the development of female secondary sex characteristics and is produced by the structures labeled 6 is

Estrogen

An enlargement of the thyroid gland often associated with an iodine deficient diet

Goiter

When a person´s level of physical activity changes, the circulatory system supplies body cells with amounts of nutrients and oxygen that are appropriate to sustain the new level of activity. This statement best illustrates the concept of

Homeostasis

which hormone does not directly regulate human reproductive Cycle?

Insulin

The maintenance of proper blood sugar level involves the storage of excess sugar in the

Liver

A similarity between the nervous system and the endocrine system in humans is that they both

Maintain Homeostasis

Some pituitary hormones cause the ovaries to secrete hormones. there ovarian hormones then influence the production of the pituitary hormone. This type of control mechanism is known as

Negative Feedback

Which structures secrete hormones that influence proper bone structure and development

Pituitary and Parathyroid

One reason for the change in wound healing time in a diabetic is that

Poor circulation reduces the supply of glucose by healthy cells

The hormone TSH stimulates the production of

Thyroxin
