Describe the neural and renal mechanisms that control blood pressure.

Andrei [34K]

Answer:

The autonomic nervous system is the main neural regulator of circulation and blood pressure in the short term and beat by beat and exerts its function through various reflexes that regulate vasomotor tone, heart rate and cardiac output. At the renal level, the renin–angiotensin–aldosterone system is possibly the most important in the maintenance of arterial homeostasis.

Explanation:

Blood pressure is regulated by a series of interrelated autonomic systems and humoral reflexes, which continually adjust the determining elements of the system (heart rate, stroke volume, total peripheral resistance and circulating volume).The effective circulating volume is controlled by a series of reflex systems, which obtain information about the perfusion pressure (baroreceptors in the carotid bulb and aortic arch), plasma osmolarity (hypothalamus) and urinary sodium (distal tubule).The kidney has its own self-regulatory mechanisms. The reduction in renal blood flow is detected at the level of the mesangial cells of the juxtaglomerular apparatus, starting the renin-angiotensin system. The increase in angiotensin II produces on the one hand local vasoconstriction, and on the other hand stimulates the production of aldosterone by the adrenal cortex with the consequent tubular reabsorption of sodium and water.Antidiuretic hormone or vasopressin (released from the hypothalamus by stimulation of arterial baroreceptors and also by stimulation of angiotensin II) also acts at the renal level, which acts as a powerful and water-saving vasoconstrictor in the distal tubule.

White matter is found in all of the following locations EXCEPT the ________. a) cerebral cortex b) corpus callosum c) corticospi

Eddi Din [679]

Answer:

cerebral cortex

Explanation:

The tissue through which the messages are relayed between different areas of the grey matter is termed the white matter.
The nerve fibers present in the white matter are surrounded by myelin due to which they appear white and hence, the name.
White matter is present in deeper parts of the brain and on the superficial parts of the spinal cord in the central nervous system.
White matter under normal conditions is absent from the cerebral cortex.

erma4kov [3.2K]

Based on the assumption that individuals seek to maximize the return (in calories and nutrients) on their labor,<u> age and gender </u>is a model used by anthropologists to how food collectors decide which animals and plants to hunt or collect and which to ignore.

<h3>What is the meaning of "Labor"?</h3>

In its most basic sense, the term "labor" refers to employment that requires heavy manual labor, typically performed by unskilled laborers. However, the term "labor" in economics refers to manual labor. It also requires mental effort. In other words, work that is done physically or mentally in exchange for payment is considered labor.

<h3>What exactly does an anthropological do?</h3>

When it comes to human origins, physical, social, linguistic, and cultural development, behavior, and the cultures, organizations, and institutions that people have built over time, anthropologists study, assess, and help shape public policy.
