A patient is scheduled for a fiberoptic colonoscopy. what does the nurse know that fiberoptic colonoscopy is most frequently use
Naya [18.7K]
During colonoscopy, a flexible Fiberoptic or video colonoscope is used to visualize, examine and photograph the large intestine including the anus, the rectum and the sigmoid, transverse and ascending colon. This procedure is most frequently used for cancer screening and for surveillance in patients with previous colon cancer or polyps. In addition, tissue biopsies can be obtained as needed and polyps can be removed and evaluated. Other uses of colonoscopy include the evaluation of patients with diarrhea of unknown cause, occult bleeding, or anemia; further study of abnormalities detected after a barium enema and diagnosis clarification and determination of the extent of inflammatory or other bowel disease. Colonoscopy is contraindicated if the patient has a suspected or documented colon perforation, acute severe diverticulitis or fulminant colitis.

how do you think living systems, such as sea stars, carry out life functions and respond to changes in their environment
pychu [463]

Answer:

Sea stars carry out life functions in diverse -and unique- ways (<em>read below</em>) and are able to respond to environmental changes through adaptations such as temperature regulation.

Explanation:

Sea stars are invertebrate organisms that belong to the Phylum Echinodermata and are adapted to life in the ocean. They carry out life functions in diverse kind of ways. Here are some examples:

  • <u>Limb regeneration</u>: they are known for the impressive ability to regenerate their limbs, which they accomplish because almost all of their vital organs are located in the arms.
  • <u>Feeding</u>: sea stars are generally carnivorous creatures. They use their suction-cupped feet to open clams, mussels, and oysters. On the other hand, there are some species that prefer to feed on detritus or organic matter.
  • <u>Locomotion</u>: these organisms are able to move thanks to their water vascular system, as they do not possess a circulatory system. Water circulates throughout their body into their feet, allowing it to extend and move.

Response to environmental changes:

According to new research evidence, these marine creatures possess unique adaptations that are extremely helpful in regard to environmental changes. They are able to regulate their own temperature during changing tides. During high tides, sea stars absorb cold water that is later used when temperatures are too hot due to warm water and sunlight. This adaptation is crucial to respond to environmental changes such as climate change.

Coral reefs only form in ocean waters between 30 N and 30 S. The reefs are confined to shallow water because?
Viktor [21]
Reef-building corals were confined to relatively shallow depths because many of these corals have microscopic algae called zooxanthellae living inside their soft tissues.
 These algae are often important for the corals’ nutrition and growth, but require sunlight for photosynthesis. There is no sunlight deep in the water.
