Hypothalamus
Click here for an animation on the relationship of the hypothalamus to the anterior and posterior pituitary glands and on the relationship of the hormones made in the hypothalamus (ADH, oxytocin, releasing hormones, and inhibiting hormones) to the anterior and posterior pituitary glands. Pituitary (also called Hypophysis)
Hormones of the Anterior Pituitary Gland (Adenohypophysis)
Hormones of the Posterior Pituitary Gland (Neurohypophysis)
What hormone decreases the blood volume?Renal Physiology
ADH, also known as vasopressin (see Chapter 35). ADH is released from the posterior pituitary (neurohypophysis) in response to increased osmolality (sensed by magnocellular neurons in the hypothalamus), decreased circulating plasma volume and/or angiotensin II.
What is released in response to low blood volume?A decrease in blood volume or low blood pressure, which occurs during dehydration or a haemorrhage, is detected by sensors (baroreceptors) in the heart and large blood vessels. These stimulate anti-diuretic hormone release.
Which of the following hormones are released in response to a decrease in blood volume quizlet?Renin is a peptide hormone secreted from the kidneys in response to low blood pressure or plasma volume. It acts as an enzyme activating the renin-angiotensin mechanism of aldosterone release, causing blood pressure to rise.
Which of the following hormones is released in response to an increase in blood volume?When blood volume and blood pressure increase, the stretched atria release Atrial Natiuretic Peptide (ANP), a cardiac hormone.
