Question 2

Signaling systems

Answer 2

But there are some hormone-driven messaging systems that are more localized.
For instance, paracrine signaling releases hormone molecules that degrade really quickly and are only received within a small region in the body.

Question 3

Pituitary gland

Answer 3

The pituitary gland, it’s the master gland, the Napoleon of the endocrine system. The pituitary gland makes hormones that instruct other glands to make other hormones, and those hormones actually get the real leg work done. The pituitary is connected to the hypothalamus, the part of the brain that acts as a liaison between the nervous system and the endocrine system. So a big part of its job is to tell your glands what to do based on information it gets from your senses and other nerve functions.

Question 4

Hypothalamus

Answer 4

The pituitary gland sits directly underneath the hypothalamus and has 2 lobes, which are actually two different glands fused together. The posterior pituitary is an extension of the hypothalamus and it secretes two hormones that are actually made by the hypothalamus. On of them is oxytocin, which stimulates contraction of the uterus during childbirth and helps with breastfeeding, but it probably also has a role in things like social recognition, pair bonding, orgasms, and anxiety. Which is interesting and weird. And the other hormone secreted by the posterior pituitary is antidiuretic hormone, which tells the kidneys to retain water. The anterior pituitary on the other hand both manufactures

Question 5

Thyroid

Answer 5

secretes a whole battery of hormones
and one of the places these hormones end up is the thyroid. The thyroid regulates your metabolism, your appetite, muscle function, blood pressure, heart rate, among other things and the way it interacts with the pituitary is a good example of a negative feedback loop, a method of communication that’s common all over the body, and especially in the endocrine system. Basically, the pituitary is like the thyroid’s thermostat. It can read how much thyroid hormone is in your bloodstream, and when its levels are low, it spits out a tiny bit of thyroid-stimulating hormone, or TSH, which travels to the thyroid. The thyroid, in turn, secretes thyroid hormone which boosts our metabolism.

Question 6

Adrenal

Answer 6

Pituitary Gland include adrenal glands. These guys sit right on top of the kidneys and are in charge of making hormones that help the kidneys maintain the level of salt
and water in your body, but they also, you may have heard, respond to stress.

Question 7

Pancreas

Answer 7

the biggest in the body. I’ve mentioned a couple of times that glands regulate the balance of solutes in your blood: This is one of the most important things that the endocrine system does, and no one does it better than your pancreas. Because its job is to regulate the levels of glucose in your blood and since glucose is what makes cellular respiration, and therefore, your life, possible, this is important. the pancreas secretes insulin into the blood. The insulin then travels around your body and stimulates pretty much every type of body cell to absorb glucose
