Maintenance of our bodies' optimal conditions
A chunk or section/ slice from a sample to look at what is inside or what something is made up of
How does the energy usage of brown fat compare to white fat?
Brown fat need alot of mitochondria to generate heat
What is the primary function of carbohydrates in the body?
To provide short term energy

Which macromolecule serves as the primary energy source for cells?
Carbohydrates
What is the primary function of the dermis?
To help our bodies with thermoregulation by sensing changes in the environment and responding
What is the role of positive feedback in the birthing process?
It helps us continuously push out oxytocin to push the baby out
What is the function of melanin in the skin?
Protect from UV rays, provide us our skins pigment/ color
What role does brown fat play in infant thermoregulation?
Creates heat for our bodies
How do proteins help our bodies?
Describe the role of the hypodermis in relation to the skin.
The hypodermis provides cushioning and insulation to our skin layers
How does the body respond to elevated blood glucose levels?
It will release insulin to lower blood sugar

Connective tissue
Discuss how the integumentary system contributes to homeostasis.
Regulates temperature, protects our skin from bacteria or contaminants and senses changes
How does aging affect the integumentary system?
Skin becomes thinner and your connective tissue loses elasticity
