Overview of Human Body Systems and Tissues

These flashcards cover the main systems of the human body, their functions, and the basic types of tissues.

Integumentary System

Composed of skin, hair, nails, and glands; primary function includes protection, sensation, and thermoregulation.

Muscular System

Consists of skeletal muscles that provide movement, maintain posture, and generate heat.

Skeletal System

Made up of bones and cartilage; provides support, protects internal organs, and facilitates movement.

Nervous System

Includes the brain, spinal cord, and nerves; responsible for control and communication within the body.

Endocrine System

Comprises glands that secrete hormones to regulate bodily functions such as growth and metabolism.

Cardiovascular System

Responsible for transporting blood, nutrients, and oxygen throughout the body; includes the heart and blood vessels.

Respiratory System

Involved in gas exchange; includes structures such as the trachea, lungs, and diaphragm.

Digestive System

Breaks down food for nutrient absorption; includes the mouth, esophagus, stomach, and intestines.

Urinary System

Filters blood to form urine; regulates fluid balance, electrolytes, and blood pressure.

Reproductive System (Male)

Produces sperm and hormones; includes structures like the testes and prostate.

Reproductive System (Female)

Produces oocytes and hormones; enables fertilization and fetal development, includes structures like the ovaries and uterus.

Tissue

A group of similar cells working together to perform a specific function; includes epithelial, connective, muscle, and nervous tissues.

Histology

The study of tissues at the microscopic level.

Epithelial Tissue

Covers body surfaces and lines cavities; functions include protection, secretion, and absorption.

Connective Tissue

Provides support and binds other tissues; includes various types like bone and blood.

Muscle Tissue

Composed of contractile cells; responsible for movement.

Nervous Tissue

Consists of nerve cells and supporting cells; responsible for transmitting impulses.
