Question

1. what is the primary goal of the endocrine system? 3.7

a) to communicate with the outside of the body by sensing, interpreting, and responding to signals
b) to maintain homeostasis
c) to breakdown food and absorb nutrients
d) to transport nutrients to all cells throughout the body

1. identify the two types of hormones found in the body. 3.2

a) protein hormones & steroid hormones
b) lipid hormones & fatty hormones
c) protein hormones & peptide hormones
d) cell hormones & local hormones

1. which of the following is true regarding the location of the pituitary gland? 3.4

a) it is located in the abdominopelvic cavity
b) it is connected to the hypothalamus in the brain
c) it is located in the throat
d) the anterior pituitary is in the brain, the posterior pituitary is in the stomach

1. the endocrine system maintains homeostasis of the hormones by using which of the following mechanisms? 3.7

a) positive feedback mechanism
b) synaptic transmission
c) negative feedback mechanism
d) action potentials

1. which is generally true of hormones? 3.1

a) exocrine glands produce them
b) they travel throughout the body in the blood
c) they affect only non - hormone producing organs
d) all hormones produce the same response

1. which of the following is true of steroid hormones? 3.2

a) they are made up of amino acids
b) they are unable to enter cells directly
c) they are made up of lipids
d) they are tyrosine based

Explanation:

1. The endocrine system's main job is to maintain homeostasis by secreting hormones.
2. The two main types of hormones are protein hormones and steroid hormones. Protein hormones are made of amino - acids and steroid hormones are made of lipids.
3. The pituitary gland is connected to the hypothalamus in the brain.
4. The endocrine system uses a negative feedback mechanism to maintain hormone homeostasis. Positive feedback amplifies a response, synaptic transmission is in the nervous system, and action potentials are also related to the nervous system.
5. Hormones are produced by endocrine glands and travel throughout the body in the blood.
6. Steroid hormones are made up of lipids. They can enter cells directly as they are lipid - soluble.

Answer:

1. B. to maintain homeostasis
2. A. Protein hormones & steroid hormones
3. B. It is connected to the hypothalamus in the brain
4. C. Negative feedback mechanism
5. B. They travel throughout the body in the blood
6. C. they are made up of lipids
