Overview of Anatomy and Physiology: Introduction To Anatomy And Physiology Worksheet
Anatomy and physiology are two closely related fields of science that study the structure and function of living organisms.
Anatomy is the study of the physical structure of organisms, while physiology is the study of how these structures function.
The study of anatomy and physiology is important because it provides a foundation for understanding how living organisms work. This knowledge is essential for a variety of professions, including medicine, nursing, and physical therapy.
Basic Anatomical Terminology
Before we can begin to study anatomy and physiology, we need to learn some basic anatomical terminology.
The anatomical position is the standard position in which the body is held for the purpose of describing its anatomy. In the anatomical position, the body is standing upright, with the feet flat on the floor and the arms at the sides.
The planes of the body are imaginary lines that divide the body into different sections. The three main planes are the sagittal plane, the coronal plane, and the transverse plane.
The terms used to describe body parts are based on their location in relation to the anatomical position. For example, the anterior (front) surface of the body is opposite the posterior (back) surface, and the superior (upper) surface of the body is opposite the inferior (lower) surface.
Organization of the Human Body
The human body is organized into a hierarchy of levels, from the smallest to the largest.
The smallest level of organization is the cell. Cells are the basic building blocks of all living organisms.
Cells are organized into tissues, which are groups of similar cells that perform a specific function. For example, muscle tissue is made up of cells that contract to produce movement.
Tissues are organized into organs, which are groups of tissues that perform a specific function. For example, the heart is an organ that pumps blood throughout the body.
Organs are organized into organ systems, which are groups of organs that work together to perform a specific function. For example, the circulatory system is made up of the heart, blood vessels, and blood.
The Integumentary System
The integumentary system is the outermost layer of the body. It consists of the skin, hair, nails, and glands.
The skin is the largest organ of the body. It protects the body from the environment, helps to regulate body temperature, and produces vitamin D.
Hair, nails, and glands are all appendages of the skin. Hair helps to insulate the body, nails protect the fingertips and toes, and glands produce sweat and other secretions.
The Skeletal System
The skeletal system is made up of bones, which provide support and protection for the body.
Bones are also involved in movement, blood production, and calcium storage.
The skeletal system is divided into two main parts: the axial skeleton and the appendicular skeleton.
The axial skeleton consists of the skull, vertebral column, and rib cage. The appendicular skeleton consists of the bones of the limbs and girdles.
The Muscular System
The muscular system is made up of muscles, which are responsible for movement.
Muscles are attached to bones by tendons. When a muscle contracts, it pulls on the bone, causing it to move.
There are three types of muscles: skeletal muscles, smooth muscles, and cardiac muscles.
Skeletal muscles are attached to bones and are responsible for voluntary movement.
Smooth muscles are found in the walls of internal organs and are responsible for involuntary movement.
Cardiac muscle is found in the heart and is responsible for pumping blood.
The Nervous System
The nervous system is made up of the brain, spinal cord, and nerves.
The nervous system controls all of the body’s functions, including movement, sensation, and thought.
The brain is the center of the nervous system. It is responsible for processing information, making decisions, and controlling movement.
The spinal cord is a long, thin bundle of nerves that runs from the brain down the back. The spinal cord carries messages to and from the brain and the rest of the body.
Nerves are bundles of fibers that carry messages to and from the brain and spinal cord.
The Endocrine System
The endocrine system is made up of glands that produce and secrete hormones.
Hormones are chemical messengers that travel through the bloodstream and control a variety of body functions.
The endocrine system is responsible for regulating metabolism, growth, reproduction, and mood.
The Cardiovascular System
The cardiovascular system is made up of the heart, blood vessels, and blood.
The heart is a muscular organ that pumps blood throughout the body.
Blood vessels are tubes that carry blood from the heart to the rest of the body and back again.
Blood is a fluid that carries oxygen, nutrients, and waste products throughout the body.
The Respiratory System
The respiratory system is made up of the lungs, airways, and diaphragm.
The lungs are two large, spongy organs that are located in the chest cavity.
The airways are a series of tubes that carry air to and from the lungs.
The diaphragm is a large muscle that separates the chest cavity from the abdominal cavity.
The respiratory system is responsible for exchanging oxygen and carbon dioxide between the blood and the air.
The Digestive System
The digestive system is made up of the mouth, esophagus, stomach, small intestine, large intestine, and rectum.
The mouth is the first part of the digestive system. It is where food is chewed and mixed with saliva.
The esophagus is a tube that carries food from the mouth to the stomach.
The stomach is a muscular organ that secretes acids and enzymes to break down food.
The small intestine is a long, coiled tube where most of the digestion and absorption of nutrients takes place.
The large intestine is a shorter, wider tube where water and electrolytes are absorbed from the remaining food.
The rectum is the final part of the digestive system. It stores waste products until they are eliminated.
The Urinary System, Introduction to anatomy and physiology worksheet
The urinary system is made up of the kidneys, ureters, bladder, and urethra.
The kidneys are two bean-shaped organs that filter waste products from the blood.
The ureters are two tubes that carry urine from the kidneys to the bladder.
The bladder is a muscular organ that stores urine until it is released through the urethra.
The urethra is a tube that carries urine from the bladder to the outside of the body.
The Reproductive System
The reproductive system is made up of the organs that are responsible for reproduction.
In males, the reproductive system includes the testes, penis, and seminal vesicles.
In females, the reproductive system includes the ovaries, uterus, fallopian tubes, and vagina.
The reproductive system is responsible for producing gametes (eggs and sperm) and for nurturing a developing fetus.
