organ systems
This system, composed of bones, cartilages, and ligaments, provides structural support and protection for the body.
What is the skeletal system?
The largest internal organ, responsible for detoxifying chemicals, metabolizing drugs, and producing bile
What is the liver
The body's ability to maintain a stable, constant internal environment despite changes in external conditions.
What is homeostasis?
his vertical plane divides the body or an organ into equal right and left halves.
What is the sagittal plane
The anatomical term referring to the anterior region of the knee, commonly known as the kneecap.
What is the patellar region?
Responsible for transporting oxygen, nutrients, and hormones to cells, this system includes the heart, blood, and blood vessels.
What is the cardiovascular (or circulatory) system?
Located in the thoracic cavity, these paired organs exchange carbon dioxide for oxygen in small sacs called alveoli.
What are the lungs?
The primary homeostatic mechanism where the output of a system counteracts or reduces the original stimulus (e.g., body temperature regulation).
What is negative feedback?
Also called the horizontal plane, this cuts across the body to divide it into superior (upper) and inferior (lower) portions.
What is the transverse plane?
The anatomical term describing the armpit area.
What is the axillary region?
This body system includes the skin, hair, and nails, acting as the primary barrier against external pathogens.
What is the integumentary system?
These bean-shaped retroperitoneal organs filter blood to eliminate waste products and regulate fluid balance.
What are the kidneys
This region of the brain acts as the body's main control center for regulating homeostatic functions like body temperature, hunger, and thirst.
What is the hypothalamus?
This vertical plane divides the body into anterior (front) and posterior (back) portions.
What is the frontal (or coronal) plane?
This term refers to the posterior region of the neck.
What is the nuchal (or cervical) region?
This system uses ductless glands to secrete chemical messengers directly into the bloodstream to regulate metabolism and growth.
What is the endocrine system?
Situated behind the stomach, this dual organ acts as an exocrine gland producing digestive enzymes and an endocrine gland releasing insulin.
What is the pancreas
Blood clotting and childbirth contractions are classic examples of this feedback mechanism, where the response amplifies the original stimulus.
What is positive feedback?
A section cut made diagonally across a body part or organ at an angle other than 90 degrees.
What is an oblique plane?
Located in the center of the abdomen, this region directly surrounds the navel.
What is the umbilical region?
Composed of vessels, nodes, and organs like the spleen, this system returns leaked fluid to the blood and defends against pathogens.
What is the lymphatic system?
Located in the right upper quadrant, this small sac stores and concentrates bile produced by the liver until needed for digestion.
What is the gallbladder
In a homeostatic control loop, this component detects a change in an environmental variable and sends input to the control center.
What is a receptor
A medical imaging scan that takes a series of transverse plane cross-sectional X-rays of the body.
What is a CT (Computed Tomography) scan?
Located inferior to the umbilical region and superior to the pubic region, it houses parts of the small intestine and urinary bladder.
What is the hypogastric region?
