Which statement regarding the endocrine system is incorrect? 1. Hormones are transported by the blood. 2. The parathyroid regulates metabolism. 3. The pituitary used to be called the “master gland. ” 4. The endocrine system regulates body processes.

The structures that neurotransmitters and hormones attach to are 1. villi 2. white blood cells 3. alveoli 4. receptors

Which substances are found on cell surfaces and respond to nerve and hormone signals? 1. starches and simple sugars 2. subunits of DNA 3. vitamins and minerals 4. receptor molecules

Identify the gland being described. 1. Produces thyroxine Thyroid 2. Regulates calcium levels in the blood Parathyroid 3. Called the master gland. Pituitary 4. Releases adrenaline. 5. The female gonads. Adrenal Ovaries glands 1. The male gonads Testes 2. Regulates Thyroid metabolism

1. According to this diagram, a gland secretes a chemical. What is the name of this chemical? Hormone 2. The organs and tissues that the chemical is transported to by the blood is made up of what kind of cells? Target cells 3. What do hormones attach to on these cells? Receptors

An important method of communication between cells is shown in the diagram. What is the chemical referred to in the diagram? 1. a hormone important in maintaining homeostasis 2. an enzyme detected by a cell membrane receptor 3. DNA necessary for regulating cell functions 4. a food molecule taken in by an organism

1. What does structure B represent? receptors 2. Explain why cell C is the target cell. Cell C has receptors that fit perfectly with the hormone.

Identify all glands labeled in the diagtam. Pituitary gland Parathyroid gland Thyroid gland Adrenal glands Pancreas Ovaries
