Human Digestive System Quiz

The process of breaking down food into a form the body can absorb and use.

The lower part of the large intestine that stores waste products until elimination.

Part of the digestive system that absorbs water from undigested food and stores waste.

Rhythmic muscle contractions that move food through the digestive system.

Where digestion begins; the food is broken down and moistened by saliva.

A liquid in the mouth that moistens food and changes starch to sugar.

A long muscular tube that carries food from the mouth to the stomach.

A muscular pouch that secretes gastric juice and breaks down food into smaller pieces.

The part of the skeleton that forms the central axis of the body, including the skull, vertebral column, and rib cage.

The part of the skeleton that includes the limbs (arms and legs) and the girdles that connect them to the axial skeleton.

The irregular bones that make up the spinal column, protecting the spinal cord.

The protective structure around the chest, protecting the lungs and heart.

26. As a child, there are 33.

The upper 7 pairs of ribs, connected directly to the breastbone.

The last two pairs of ribs that are not connected to the breastbone.

The soft tissue inside bones that produces blood cells.

A group of organs that work together to perform a specific function in the body.

The system responsible for breaking down food into nutrients the body can absorb.

The system that takes in oxygen and releases carbon dioxide.

The system that carries oxygen, nutrients, and waste throughout the body.

The system that controls and coordinates body functions, including senses, movement, and thoughts.

The system responsible for movement, support, and protection of the body.

Different organ systems depend on each other to keep the body functioning properly.

If one organ system fails, other systems may be affected, leading to health problems.

The main part of the nervous system, made up of the brain and spinal cord.

The primary organ of the central nervous system, housed within the skull. It receives sensory information, controls movement, emotions, and thought.

The largest part of the brain, responsible for sensory processing, emotions, consciousness, learning, and voluntary movement.

Located beneath the cerebrum, this part coordinates muscle movement, balance, and helps with learning new skills.

The base of the brain that connects to the spinal cord and controls essential functions like breathing, heart rate, and digestion.

A long cord of nerve tissue extending from the brain stem down the backbone, transmitting signals between the brain and body.

The network of nerves branching out from the spinal cord to all parts of the body, collecting sensory information and delivering motor commands.

Ptyalin is an enzyme found in saliva that breaks down starch into sugar. It helps in the initial digestion of carbohydrates in the mouth.

The esophagus is a muscular tube that carries food from the mouth to the stomach. It uses muscle contractions (peristalsis) to move food down.

The stomach is a muscular pouch that churns and mixes food with gastric juices. It breaks down food into smaller pieces and helps digest proteins.

The anus is the lower part of the digestive system where waste products are expelled from the body.

The large intestine absorbs water from undigested food and forms stool. It plays a crucial role in waste elimination.

A 'true' statement is one that is accurate and corresponds to reality.

A 'false' statement is one that is inaccurate or does not correspond to reality.

Additional activities refer to extra tasks or exercises that extend learning beyond the basic material.

The nervous system is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, while the PNS consists of nerves connecting the CNS to the rest of the body.

The central nervous system (CNS) is composed of the brain and spinal cord. It serves as the body's control center, processing information and sending out commands.

The peripheral nervous system (PNS) consists of nerves that connect the central nervous system (CNS) to the rest of the body, relaying information and carrying out commands.

The brain acts as the body's control unit, responsible for interpreting messages, making judgments, processing sensations, and enabling creative thinking.

The spinal cord, encased in the spinal column, acts as a link between the brain and the peripheral nervous system. It also handles reflex actions, protecting the body from immediate harm.

Neurons, or nerve cells, are the fundamental working units of the nervous system. They transmit information between nerve cells, muscles, and glands.

The nervous system interacts with the skeletal system in several ways: the skull protects the brain, the brain controls bone movement, the spinal column safeguards the spinal cord, and bones supply calcium essential for nervous system function.

Reflex actions are instantaneous movements that protect the body from harm. They are controlled by the spinal cord without conscious thought.
