Explain how autonomic nerves that innervate the smooth muscle layer around bronchioles can influence the volume of air reaching a particular region of the lung

The autonomic nervous system or visceral nervous system (also called the vegetative nervous system) is the part of the nervous system responsible for functions not subject to voluntary control.

The information converges at the level of an integrative center, the nucleus of the solitary tract, located in the central nervous system. This one sends information in the efferent ways to modify among others the dilation and retreat of the bronchi.

The dilation of the bronchi and bronchioles makes that the passage of air in the lungs is more important (as the diameter grows). The shrinking bronchi and bronchioles that the diameter is reduced and therefore the passage of air will be less important.

The Autonomic nervous system( of the sympathetic, parasympathetic and enteric  nervous system) is concerned  with innervation of muscles concerned with  involuntary control of breathing, heart rate, urination,digestion etc,

it is under the control of the brain stem and the spinal cord. Structurally, the integration of sensory inputs from the limbic sytem for coordinated response by the autonomic system    takes place in the hypothalamus.

Smooth muscles in the walls of the bronchioles are innervated by both sympathetic and parasympathetic nervous system.Thus the volume of the bronchioles is regulated by these innervation. Constriction of these smooth muscles is stimulated by parasympathetic nerves. Innervation by the latter from the brain stem through the spinal cord, leads to contaction of smooth muscles which constricts the bronchioles, reducing the  diameter (bronchocontriction),and therefore the volume of airflow  through through it ( bronchioles.)

Explanation:

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
