Benefits of Segmentation Biology
Segmentation biology either refers to gastrointestinal motility or division, or the repetitive segmentation of plant and animal body. While the body is divided into different parts, each part has a different mechanism for growth. In other words, segmentation allows different body regions to develop for different purposes or uses.
1. Efficient movement
Segmentation plays an essential role in how animals move from one place to another. For example, segmented animals such as worms and centipedes remain segmented. On the other hand, others like humans or flies adapt a segmented arrangement which is then modified until the structure disappears.
2. Detect prey
Segmented animals somehow resemble a train and use their segments effectively between specialized compartments. They have a typical mouth and head, as well as sensory organs that help to detect prey from behind thus ward off imminent danger. However, the digestive system is not a classic segment.
Segmentation also allows for specialization with respect to bodily regions. Specialization is evident in annelids and is more pronounced in the body structure of arthropods. For example, the worms occupy different niches. They include crawlers and swimmers preying upon smaller animals, as well as the sitters and so forth.
4. Soil aeration
Oligochaete worms on the other hand include water segmented animals. This group consists of earthworms, which extract nutrients directly from the dirt, recycling and aerating soil at the same time.
5. Medicinal purposes
Leeches are used for medicinal purposes as they act as anti-clotting agents. In most cases, they are used during the reattachment of detached fingers and limbs ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ their attachment point prevent excessive blood loss.
6. Better adaptation
Segmented animals such as arthropods and annelids are adapted to suit different niches. For example, horsetails provide a clear illustration of segmentation.
Segmentation is an adaptive feature that allows body organs to grow differentially, each suited for a specific purpose.
