Question

As a student in an esthetic program, Hannah is tasked with building a three-dimensional model of the layers of the skin. Her model must include captions describing each skin layer and connect skin histology and physiology to esthetics. Hannah visits a craft store to purchase supplies from which she will construct her model.

Hannah adds thin straws to her model to represent the _____ in the dermis, which provide the skin with oxygen and nutrients.

A) Nerves
B) Blood vessels
C) Lymphatics
D) Sweat glands

Answer 1

Hannah uses thin straws to represent the blood vessels in the dermis of her skin model, which are required to supply the skin with oxygen and nutrients.

Step-by-step explanation:

Hannah adds thin straws to her model to represent the blood vessels in the dermis, which provide the skin with oxygen and nutrients. The correct answer is B) Blood vessels. The dermis is the inner and thicker layer of skin situated underneath the epidermis, containing connective tissue, and houses various structures including blood vessels, hair follicles, sweat glands, and sebaceous glands.

These blood vessels are crucial for supplying oxygen and essential nutrients to the skin. The dermis also connects to the hypodermis, which contains adipose tissue for fat storage and protection and provides the skin with strength and elasticity through collagen and elastin fibers.
