Insulin Production and Liver Response

Which type of pancreatic cells produce insulin?

What triggers the release of insulin from beta cells?

How does the liver respond to insulin?

What is the primary mechanism of cholesterol transport in the bloodstream?

How can excess cholesterol contribute to heart attacks?

What is the primary function of aldosterone?

Which hemisphere of the brain would be most affected if a person experiences numbness on the right side of their body?

What is the primary role of osteoblasts in bone remodeling?

Why is Jane at a high risk of bone fractures?

What is the effect of high altitude on breathing?

How does atmospheric pressure affect the inhaling process?

What type of muscle fibers would be more prevalent in an endurance runner like Jane?

Insulin and Pancreatic Cells

Beta cells in the pancreas produce insulin in response to high blood sugar levels.

Insulin's Effect on the Liver

Insulin triggers the liver to convert glucose to glycogen for storage.

Cholesterol Transport

Cholesterol is transported in the bloodstream by lipoproteins.

Cholesterol's Role in Heart Attacks

Excess cholesterol can lead to the formation of plaques that narrow arteries and restrict blood flow, increasing the risk of heart attacks.

Aldosterone's Function

Aldosterone increases sodium and water reabsorption in the kidneys, raising blood pressure.

Brain Hemispheres and Stroke

A stroke affecting the right hemisphere, parietal lobe can cause loss of sensation on the left side of the body.

Brain Hemisphere Control

The right hemisphere controls sensory input from the left side of the body.

Bone Remodeling

Osteoclasts break down bone tissue, while osteoblasts build it up.

Osteoporosis and Bone Fractures

High activity of osteoclasts leading to bone resorption and reduced bone density increases the risk of bone fractures.

Muscle Fiber Types

Endurance running, like Jane's, leads to a higher amount of type I fibers.

High-Altitude Breathing

Breathing becomes harder at high altitudes due to the lower air pressure and reduced oxygen availability.
Inhaling involves muscle contraction and is harder at lower atmospheric pressures.
