How does the Digestive system help maintain homeostasis?
Gnesinka [82]

Answer:

The bacterial flora in the intestines are essential to homeostasis in the body, they not only break down food so the nutrients can be absorbed, they produce vitamins like biotin and vitamin K and guard against harmful bacteria that enter the system. While your heart is a vital organ, the brain (and the nervous system that attaches to the brain) make up the most critical organ system in the human body. The digestive system ordinarily gets 20% to 25% of the oxygenated blood pumped out by the heart and the receptors in muscles provide the brain with information about body position and movement, the brain controls the contraction of skeletal muscle the nervous system regulates the speed at which food moves through the digestive tract.

serious [3.7K]

High littoral zone has greatest abundance of marine organisms.

<h3>What is High littoral zone?</h3>

The intertidal zone, also known as the "littoral zone," refers to the seashore that is covered during high tide and exposed during low tide, revealing a unique biome that survives under such fluctuating conditions.

<h3>Where are most marine organisms found?</h3>

The majority of ocean life can be found in coastal habitats on the continental shelf, despite the fact that this area accounts for only 7% of total ocean area. The majority of open ocean habitats are found in the deep ocean beyond the continental shelf. Species that live in the oceans and on the coasts can help to create new habitats.
