Human Body Systems Quiz

Body's Largest Organ

• The skin is the body's largest organ.
• It acts as a protective barrier against environmental hazards.
• It regulates body temperature.
• It provides sensory information.
• An adult's skin covers approximately 20 square feet on average.
• It plays a crucial role in overall health and well-being.

Brain Function

• The cerebrum controls voluntary movements.
• It's the largest part of the brain.
• It has two hemispheres.
• The motor cortex plans, controls, and executes voluntary actions.
• The cerebrum is responsible for controlling voluntary movements.

High Blood Pressure

• The medical term for high blood pressure is hypertension.
• High blood pressure is when blood pressure against artery walls is consistently high.
• It's a risk factor for heart disease, stroke, and other health problems.
• Hypertension often requires lifestyle changes and medication for management.

Vitamin C Deficiency

• Scurvy is caused by a deficiency of Vitamin C.
• Vitamin C is essential for the synthesis of collagen in humans.
• Scurvy was common among sailors and pirates.
• Sailors and pirates lacked fresh fruits and vegetables.

Red Blood Cells

• Red blood cells (erythrocytes) transport oxygen.
• They carry oxygen from the lungs to the body.
• Hemoglobin binds oxygen for transport.
• Red blood cells are primarily responsible for transporting oxygen from the lungs to the rest of the body.

Type 1 Diabetes

• Type 1 diabetes is caused by autoimmune destruction of insulin-producing cells.

Insulin Production

• The pancreas produces insulin.
• Insulin helps regulate blood sugar.
• Cells absorb glucose from the bloodstream.
• The pancreas is a vital organ behind the stomach that regulates blood sugar levels.

Small Intestine Function

• The small intestine's primary function is nutrient absorption.
• It absorbs vitamins, minerals, and other nutrients.
• Its lining with villi and microvilli increase surface area for absorption.
• The small intestine absorbs nutrients from food.
