Sobre la pregunta:
Cucigrama. Pregunta 1 vertical. Absorbe nutrientes por medio de micro vellosidades que recubren y aumentan la superficie de absorción
Answer:
Intestino delgado
Explanation:
El intestino delgado es el organi mas largo del tubo digestivo, pudiendo medir 7 metros de longitud y 3 cm de diametro. Se caracteriza por estar sumamente plegado sobre si mismo. La primera porcion, llamada duodeno, recibe secresiones de glándulas biliar y pancreática, y las mezcla con enzimas digestivas. Esta mezcla se encarga de degradar la comida y transformarla en sustancias solubles, como amino ácidos.
Es en el intestino delgado donde ocurre la absorción de nutrientes. Las paredes intestinales estas cubiertas por microvellosidades que aumentan la superficie de absorción.
Las microvellosidades son células que componene el epitelio columnar, y que extienden proyecciones hacia el lumen del organo.
The epithelium with a single layer of tall cells is classified as simple cuboidal epithelium.
Epithelium is one of the major types of body tissue that line the outer surfaces of organs and blood vessels throughout the body.
The epithelium performs the following functions that include:
- protection,
- secretion,
- secretion, absorption,
- excretion,
- filtration,
- diffusion, and
- sensory reception.
There are also different types of epithelium found in different parts of the body. A typical example is the simple cuboidal epithelium.
Simple cuboidal epithelium are single layered epithelium that are as tall as they are wide (cuboidal in shape).
They are found lining areas that are active in secretion and absorption.
Therefore, the epithelium with a single layer of tall cells is classified as simple cuboidal epithelium.

1. Regulation of glucose blood levels is an example of negative feedback mechanism.
Negative feedback mechanism is a control mechanism involved in homeostasis maintain, in this case maintenance of glucose blood levels in normal range.
Negative feedback mechanism contains sensory system that detects the changes, control system that responds to change and activates mechanisms of effector system that reverse the changes in order to restore conditions to their normal levels.
• Pancreatic cells-sensors
• Insulin-control system
• Body cells- effector cells
2. Blood glucose levels change throughout the day because of the food consumption, but in healthy individuals levels of glucose are successfully regulated via the mechanism of hormones such as insulin and glucagon in a process called glucose blood regulation.
This tight regulation of pancreatic hormones is referred to as glucose homeostasis. Insulin lowers blood sugar and glucagon raises it.
3. If the beta cells are destroyed by an autoimmune disease (immune system attacks its own cells), there would be no insulin release, and consequently, the glucose blood levels would be increased.
Diabetes type I is a metabolic disorder caused by the destruction of insulin-producing pancreatic beta cells.
