What else can I help you with?
Where can secretion and absorption be found in the body?
Secretion and absorption processes primarily occur in the digestive system. Secretion of digestive enzymes and acid takes place in the stomach, pancreas, and small intestine, while absorption of nutrients occurs mainly in the small intestine through its lining known as villi.
What is the role of nerves tissue in the small intestine?
You have local nerve plexus in case of small intestine. The small intestine is also supplied by nerves from parasympathetic and sympathetic nervous system. The parasympathetic supply augments the peristalsis, secretion of enzymes. Sympathetic nerves inhibit the same. Together they work better.
Describe a digestive secretion that behaves similarly to a detergent?
Bile is a digestive secretion that behaves similarly to a detergent. It emulsifies fats, breaking them into smaller droplets to increase surface area for digestive enzymes to act upon. This helps in the digestion and absorption of fats in the small intestine.
Which nervous system division controls smooth muscle contraction and secretion in the digestive system?
Autonomous nervous system. Consisting of Parasympathetic nervous system and Sympathetic nervous system. Parasympathetic nervous system increases the secretions of digestive tract and Sympathetic system decreases the secretions. Parasympathetic system increases the contractions of smooth muscles and increases the rate and force of peristalsis and Sympathetic system does vise verse.
What effects would the sympathetic and parasympathetic system have on insulin secretion?
The sympathetic system tends to inhibit insulin secretion, as it is involved in the "fight or flight" response where energy is needed quickly. On the other hand, the parasympathetic system stimulates insulin secretion, as it is known as the "rest and digest" system that promotes nutrient absorption and storage.

What is an example of secretion?
An example of secretion is the release of digestive enzymes by the pancreas into the small intestine to aid in the digestion of food.
What is the effect of parasympathetic stimulation on this salivary glands?
Parasympathetic stimulation increases saliva production in the salivary glands by causing the release of acetylcholine, which binds to receptors on the gland cells and triggers the secretion of saliva. This response helps with digestion and keeps the mouth moist.

What is the parasympathetic and Sympathetic effect on the stomach?
The parasympathetic is stimulatory to stomach , increase the gastric secretion and motility while the sympathetic is inhibitory , decrease the gastric secretion and motility

Parasympathetic system increases the contractions of smooth muscles and increases the rate and force of peristalsis and Sympathetic system does vise verse.
What nervous system initiates internal secretion contraction and absorption?
The parasympathetic nervous system is responsible for initiating internal processes like secretion, contraction, and absorption. It is often referred to as the "rest and digest" system because it promotes activities that help the body conserve energy and promote digestion. Activation of the parasympathetic nervous system leads to increased digestive enzyme and acid secretion, smooth muscle contraction in the digestive tract, and enhanced nutrient absorption.
How does PNS stimulation affect the lungs?
parasympathetic system (PSNS) will a)vasoconstrict the lumen of airway by contracting smooth muscle cells along the conducting passage via M3 Receptor, b)increase mucus secretion via M3 Overall it'll interfere with normal breathing pattern and obstruct normal breathing.
What best demonstrates an example of cooperation of the parasympathetic and sympathetic nervous systems?
The best example of cooperative autonomic effects is seen in controls of the external genitalia. Parasympathetic stimulation causes vasodilation of blood vessels in the external genitalia, and is responsible for erection of the male penis or female clitoris during sexual excitement. Sympathetic stimulation then causes the ejaculation of semen by the penis or reflex contractions of the vagina during an orgasm.
What nervous system controls glandular secretion?
sympathetic and parasympathetic
What effects would the sympathetic and parasympathetic system have on insulin secretion?
The sympathetic system tends to inhibit insulin secretion, as it is involved in the "fight or flight" response where energy is needed quickly. On the other hand, the parasympathetic system stimulates insulin secretion, as it is known as the "rest and digest" system that promotes nutrient absorption and storage.
