Study Notes

Respiratory System

Function includes intake of oxygen and removal of carbon dioxide.
Key organs are the lungs, pharynx, larynx, and trachea.

Integumentary System

Provides protection from external environment and pathogens.
Regulates body temperature and eliminates waste.
Comprises skin, nails, and hair.

Muscular System

Responsible for the movement of cardiovascular, digestive, and skeletal systems.
Contains cardiac muscle, smooth muscle, and skeletal muscle.

Circulatory System

Delivers nutrients and oxygen to cells while removing carbon dioxide waste.
Main organs include the heart, arteries, veins, and blood.

Digestive System

Functions to bring nutrients and water into the body.
Organs involved are mouth, pharynx, esophagus, stomach, small intestines, rectum, and salivary glands.

Urinary System

Eliminates liquid waste from the body.
Composed of kidneys, bladder, and urethra.

Nervous System

Facilitates communication via electrical impulses and regulates other body systems.
Key structures include the brain, spinal cord, nerves, and sensory organs (eyes, ears, tongue, nose).

Immune System

Functions to kill and remove foreign invaders such as pathogens.
Primarily consists of white blood cells.

Skeletal System

Provides support, protection, facilitates movement, stores minerals, and produces blood cells.
Made up of bones, cartilage, joints, and ligaments.

Endocrine System

Sends messages throughout the body using chemical signals (hormones).
Key organs are the hypothalamus, thymus, thyroid, adrenal gland, pancreas, testis, and ovary.

Reproductive System

Transmits genetic information by producing offspring through sexual reproduction.
Organs include testes, epididymis, urethra, prostate, ovary, and vagina.

Lymphatic System

Drains excess fluid and supports immune response by producing immune cells.
Comprised of the spleen, lymph nodes, thymus, and tonsils.
