Homeostasis and body systems test review

The cardiovascular system is responsible for transporting _____,_____ and ______ throughout the body

Oxygen, Nutrients, and hormones

How does the cardiovascular system help maintain homeostasis?

-Carrying oxygen and nutrients to cells

-Removing waste like carbon dioxide

--Controlling body temp

Integumentary system: This system includes the ____,___ and ____

Skin, hair, and nails

Integumentary system: It helps protects the body, regulate, temperature, and produce ____ when exposed to sunlight

vitamin D

Why is Vitamin D important for homeostasis?

-Absorbs calcium from food, which is needed for strong bones and teeth.

-Maintain healing muscles and nerves.

-Support the immune system to fight off illness.

The hypothalamus is located in the ____ and serves as the body’s main ____ for maintaining homeostasis

Brain, Control center

Normal blood glucose levels before eating should be between ____ and ___ mg/dL

90 and 130

Blood Glucose Regulation: The _____ monitors and regulates theses levels releasing ____ to lower blood sugar and ____ to raise it

Pancreas, Insulin, and glucagon

After you eat a large meal, which hormone increases—insulin or glucagon?

Insulin increases. A large meal raises your blood sugar levels in response, the pancreas releases insulin to help move sugar from the blood into your cells for energy or storage. This helps lower blood sugar and keeps it in a healthy range
