which of the statements is true of the gastric cavity of cnidarians? digestive enzymes released into the gastric cavity allow th
podryga [215]

This sentence is true in the case of gastric cavity of cnidarians - digestive enzymes released into the gastric cavity allow the consumption of whole prey such as fish.

Extracellular digestion is carried out by cnidarians, in which the cells that line the gastrovascular canal receive the nutrients and enzymes split down the food particles. With only one opening, the gastrovascular cavity that doubles as both the mouth and the anus in cnidarians acts as their only digestive system. There is only one entrance in the central gastro-vascular cavity, which serves as both a mouth and a drain for waste. Digestion occurs both within and outside of cells.

Cnidarians consume food through their lips, and the coelenteron then breaks it down. Waste products are subsequently eliminated either via the mouth or via cell surface via water circulation, while nutrients are then sent to other parts of the body for use.

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.
