00:01 The general principle of the endocrine system and the hypothalamic pituitary axis. 00:08 Let's first start off by looking through some of the major components of the endocrine system. 00:16 The hypothalamus and the pituitary go together quite well. 00:20 The hypothalamus control many of the pituitary secretions. 00:24 These are both from the anterior and posterior pituitary. 00:28 The thyroid and parathyroid glands are going to be very important for releasing T3,T4 and parathyroid hormones. 00:37 The adrenal glands located just above the kidney as well as the pancreas, which have both an endocrine component and an exocrine component. 00:47 And finally the gonads for both the male and female all part of the endocrine system. 00:52 And let's talk through many of those different hormones individually. 00:59 There are a few other tissues in the body that do produce hormones. 01:05 And again a hormone is a signaling molecule that is put into the blood, travels around in circulations and binds to a target tissue. 01:14 Beside the major one, adipose tissue can serve as a place in which hormones are derived and secreted. 01:24 Leptin is the primary hormone here. 01:28 The heart produces a couple of hormones. 01:31 ANP Atrial natriuretic peptide and BNP Brain natriuretic peptide. 01:37 The kidney also produces some hormones. 01:39 Things like EPO Erythropoietin. 01:44 The liver participates in endocrine control by releasing insulin like growth factors. 01:51 And then the intestines and the stomach round it out as there are many different hormones released such as gastrin and secretin. 01:59 They're going to be very important in the digestive process but really only act pretty locally in the GI system.
The lecture Endocrine System and Hypothalamic-Pituitary Axis (HPA) by Thad Wilson, PhD is from the course Endocrine Physiology.
Which of the following hormones is produced by the heart?
What is the source of leptin?
