Study Notes
Anatomy and Physiology
- Anatomy is the scientific discipline that investigates the structure of the body.
- Physiology is the scientific discipline that deals with the processes or functions of living things.
Approaches to the Study of Anatomy
- Systemic Anatomy: studies the body systems, such as the cardiovascular, nervous, skeletal, and muscular systems.
- Regional Anatomy: studies the organization of the body by areas, such as the head, abdomen, or arm.
Goals of Physiology
- To understand and predict the body’s responses to stimuli.
- To understand how the body maintains internal conditions within a narrow range of values in the presence of a continually changing internal and external environments.
Importance of Studying Human Anatomy and Physiology
- Provides the basis for understanding disease.
- Essential for students who plan a career in the health sciences.
- Helps in making informed decisions about personal health care or that of a loved one.
- Allows distinction between useful medical treatments and those that may be harmful.
Levels of Organization for the Human Body
- Human Organ Systems
Overview of Human Organ Systems
Integumentary System
- Consists of skin, hair, and nails.
Endocrine System
- Produces hormones that control many body functions, including metabolism, growth, and sexual development.
- The pituitary gland is the master gland that produces hormones that control other endocrine glands.
Cardiovascular System
- Includes the heart, blood, and three types of blood vessels: arteries, veins, and capillaries.
- Main function is for transport, delivering oxygen and nutrients to cells and removing waste materials.
Urinary System
- Includes the kidneys, which filter excess water and waste from the blood and form urine.
- Kidneys also produce enzymes and hormones that help regulate blood pressure, red blood cell production, and calcium and phosphorus balance.
Respiratory System
- Includes nasal passages, lungs, and trachea.
- Main function is to deliver oxygen to the blood and remove carbon dioxide from the body.
Lymphatic System
- Consists of a network of lymph vessels and ducts that collect excess fluid from tissues and transport it to the bloodstream.
- Includes lymph nodes and the spleen, which remove pathogens and cellular debris from the lymph or blood.
Digestive System
- Consists of the mouth, esophagus, stomach, and small and large intestines.
- Includes accessory organs, such as the pancreas and liver, which produce enzymes and other substances needed for digestion.
Reproductive Systems
- The only body system that differs substantially between individuals.
- Female Reproductive System: consists of the ovaries, uterine tubes, uterus, and other associated structures.
Explore the basic concepts of anatomy and physiology, including the structure and functions of the human body. Learn about systemic anatomy focusing on body systems and regional anatomy studying the organization of the body.
