4. What is an example of positive feedback?

Shtirlitz [24]

Answer:

Explanation:

It is known as lactation. The suckling action of an infant produces prolactin, which leads to milk production; more suckling leads to more prolactin, which in turn leads to more lactation. This is a positive feedback system as the product (milk) produces more suckling and more hormone. When the child is no longer breast feeding, the prolactin drops off and milk production goes down.

Explain the importance of immunological memory cells. Describe in detail how and when memory cells arise and explain how they fo

Vlad1618 [11]

Explanation:

Immunological memory is the property of the immune system to store information about a stimulus so it can mount an effective response if it encounters the same stimulus again being this second response quicker and stronger even after years since the first encounter.

This kind of response is dependent on many subpopulations within T and B lymphocytes and NK cells. When encountering an antigen, B cells recognize it by membrane antibody specifically binding to the antigen and then being activated to expand rapidly with their progeny clones differentiating into plasma and memory B cells, these last ones have a long life span to remain in the body, ready when another encounter with the same stimulus occurs, this is how the basis for effective immunizations happens.

I hope you find this information useful! Good luck!

When the vasomotor center of our brain wishes to increase blood pressure, it increases ____________ signals causing ______.

dlinn [17]

When the vasomotor center of our brain wishes to increase blood pressure, it increases the heart rate signals causing The greater contraction of the heart causes more blood vessels to constrict, increasing the blood vessels' resistance.

By speeding the heartbeat, making the heart beat harder, and constricting some blood vessels, the sympathetic nervous system increases blood pressure. This will enhance the vessels' resistance.

What controls blood pressure by the vasomotor center?

The vasomotor center modifies the tone of the vascular smooth muscle. Both the local and systemic blood pressure are impacted by this. The vasomotor center produces increased sympathetic tone when blood pressure lowers. This causes an increase in blood pressure.

How is blood pressure regulated?

The autonomic nervous system has short-term control over blood pressure (ANS). Baroreceptors are capable of detecting changes in blood pressure. These are situated in the carotid sinus and aortic arch. High arterial pressure causes the blood vessel wall to stretch, activating the baroreceptors.

What systems regulate peripheral resistance in the vasomotor center?

The vasomotor center in the tunica media regulates smooth muscle contraction or vessel tone. Circulating output is impacted by changes in peripheral resistance, pressure, and flow. The majority of these neurons are in charge of causing sympathetic neurons to release the neurotransmitter norepinephrine.
