What Are The Four Primary Tissues In Adult Vertebrates
Bio 112 Exam #4 Homework
Animal Body and How It Moves
1. Briefly describe the body of all vertebrates? A tube within a tube, a digestive tract- long tube from mouth to anus that is suspended in coelom, coelom subdivided into two cavities- separated by diaphragm in mammals and some reptiles. Peritoneal cavity- stomach, intestines, liver. Thoracic cavity- heart and lungs. All vertebrate bodies supported by internal skeleton skill around brain and vertebra around spinal cord and dorsal nerve cord.
2. What are the four levels of organization in vertebrate bodies? Cells, tissues, organs, organ systems.
3. What are tissues? Groups of cells similar in structure and function are organized into tissues. What are the four primary tissues in adult vertebrates? Epithelial, connective, muscle, nerve. …show more content…
Explain the regulatory functions of the liver. Liver chemically modifies substances absorbed in the gastrointestinal tract before they reach the rest of the body, alcohol and drugs metabolized in liver, also removes toxins and poisons and converts them into less toxic forms, liver regulates many compounds such as steroid hormones, and produces most proteins found in blood plasma.
18. How is blood glucose regulated? After a carbonhydrate-rich meal, the liver and skeletal muscles remove excess glucose from blood and store it as glycogen, stimulated by insulin, when glucose levels decrease the liver secretes glucose in the blood, breakdown of glycogen stimulated by glucagon, gluconeogenesis- process of converting other molecules into glucose.
19. What are two purposes of ingested food? Provides source of energy, and provides raw materials that cannot be manufactured by the organism When is excess energy stored as glycogen and fat? If the amount of food energy taken in is greater than the energy consumed per day, the excess energy will be stored in glycogen and fat, as glycogen reserves are limited, ingestion of excess food energy results primarily in the accumulation of
