Human Anatomy Quiz

Heart

• The heart is a muscular organ that pumps blood throughout the body.
• It is located in the chest cavity, slightly to the left of center.
• The heart is made up of three layers: the outer layer (epicardium), the middle layer (myocardium), and the inner layer (endocardium)

Digestive System

• The digestive system is responsible for breaking down food and absorbing nutrients.
• It includes the mouth, esophagus, stomach, small and large intestines, and rectum.
• The digestive system is also responsible for eliminating waste products.

Glands

• Glands are organs that produce hormones.
• Hormones are chemical messengers that regulate many bodily functions.
• Examples of glands include the pituitary gland, thyroid gland, and pancreas.

Muscles

• Muscles are responsible for movement.
• They contract and relax to produce movement.
• There are three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle.
• Skeletal muscle is attached to bones and is responsible for voluntary movement.
• Smooth muscle is found in the walls of organs and is responsible for involuntary movement.
• Cardiac muscle is found only in the heart and is responsible for pumping blood.

Nerves

• Nerves are responsible for transmitting signals throughout the body.
• They are made up of specialized cells called neurons.
• Nerves transmit signals to and from the brain, spinal cord, and other organs.

Electrical Signals & Muscle Contraction

• Muscles require electrical signals to contract
• These signals travel from the surface of the muscle to the inside.
• The electrical current is generated by the nervous system.

Abdominal Cavity

• The abdominal cavity is the space located between the diaphragm and the pelvis.
• The abdominal cavity contains many organs, including the stomach, intestines, liver, and kidneys.

Shivering

• Shivering is a reflex that helps to warm the body.
• When the body is cold, involuntary muscle contractions occur.
• These contractions generate heat, which helps to maintain core body temperature.

Glycogen Storage

• Glycogen is a storage form of glucose (sugar).
• The body stores glycogen in the liver and muscles for energy.
• When blood sugar levels are low, glycogen is broken down into glucose to provide energy to the cells.

Cell Structure

• A muscle cell is composed of one muscle fiber.
• The cell is comprised of bundles of protein filaments.
• These filaments slide past each other during muscle contraction.
