B) Shivering and vasoconstriction C) Increased heart rate D) Increased breathing rate Scenario 2: Regulation of Blood Sugar Levels After eating a meal,blood sugar levels rise.The pancreas detects this increase and releases insulin, a hormone that facilitates the uptake of glucose by cells for energy or storage. When blood sugar levels drop the pancreas releases glucagon, which promotes the release of glucose stored in the liver back into the bloodstream. Multiple-Choice Questions: 1. What role does insulin play in blood sugar regulation? A) It raises blood sugar levels B) It helps lower blood sugar levels C) It stores glucose in the liver D) It blocks glucose uptake 2. What triggers the release of glucagon? A) High blood sugar levels B) Low blood sugar levels C) Increased insulin production D) Eating a meal 3. How does the pancreas respond to high blood sugar levels? A) It releases glucagon B) It releases insulin C) It releases water D) It stops producing hormones 4. What might happen if the body becomes resistant to insulin? A) Blood sugar levels decrease B) Elevated blood sugar levels may occur C) The pancreas will stop working D) The body will produce more insulin 5. How does the body maintain blood sugar levels during fasting? A) By releasing insulin B) By releasing glucagon C) By absorbing glucose from food D) By storing more glycogen Definition of Homeostasis: 6. Homeostasis is the process by which your body keeps its internal stable and balanced, even when Meet outside change. It's body's way of maintaining very what conditions for things to work properly, such as keeping mainingy temperature, balances fuilds and levels of nutrients. For example, when you get too hot, your body to cool down. When you're cold, your body shivers to warm up. Homeostasis helps ensure that your body's systems function well, so you can stay healthy and active! a situation where your body might experience accident in nomoriostasis.

Answer 1

**Respuestas a las Preguntas de Opción Múltiple:**1. **B) Disminuye los niveles de azúcar en la sangre.** La insulina facilita la absorción de glucosa por las células, reduciendo así la glucosa en sangre.2. **B) Bajos niveles de azúcar en la sangre.** La liberación de glucagón se desencadena cuando los niveles de azúcar en la sangre son bajos.3. **B) Libera insulina.** El páncreas libera insulina en respuesta a niveles altos de azúcar en la sangre.4. **B) Pueden ocurrir niveles elevados de azúcar en la sangre.** La resistencia a la insulina impide que las células absorban la glucosa de manera eficiente, lo que resulta en hiperglucemia.5. **B) Liberando glucagón.** El glucagón estimula la liberación de glucosa almacenada en el hígado, manteniendo los niveles de azúcar en sangre durante el ayuno.**Definición de Homeostasis y Ejemplo de Desequilibrio:**6. La definición proporcionada es correcta. La homeostasis es el proceso de mantener un ambiente interno estable.**Ejemplo de desequilibrio homeostático (hipotermia):**Imagina una situación donde una persona se pierde en la montaña en un día frío y con nieve. Su cuerpo experimentará una pérdida de calor más rápida de lo que puede generarlo, llevando a la hipotermia.**Síntomas:*** **Temblores:** El cuerpo intenta generar calor a través de contracciones musculares involuntarias.* **Vasoconstricción:** Los vasos sanguíneos en las extremidades se contraen para reducir la pérdida de calor.* **Confusión y letargo:** La disminución de la temperatura corporal afecta la función cerebral.* **Piel fría y pálida:** Debido a la vasoconstricción.* **Frecuencia cardíaca y respiratoria lentas:** A medida que la hipotermia progresa, las funciones corporales se ralentizan.**Respuesta del cuerpo:**Además de los temblores y la vasoconstricción, el cuerpo intentará:* **Aumentar el metabolismo:** Para generar más calor, aunque esto es menos efectivo en hipotermia severa.* **Liberar hormonas del estrés:** Como la adrenalina, que puede aumentar temporalmente la producción de calor.**Importancia de la intervención:**Si la hipotermia no se trata, puede llevar a la pérdida del conocimiento, daño a órganos vitales e incluso la muerte. Es crucial buscar atención médica inmediata si se sospecha de hipotermia.
