Cells and Homeostasis
This smallest structural and functional unit can carry out all basic life processes
What is the cell?
The chin is above the abdomen. State the correct directional term.
What is superior?
In this standard reference posture, a person stands upright with arms at the sides and palms facing forward.
What is anatomical position?
The cranial and vertebral cavities are the two subdivisions of this major cavity
What is the dorsal body cavity?
The head, neck, and trunk form this major body region
What is the axial region?
What is a mitocondrion?
The sternum is located in front of the vertebral column. State the correct term.
What is anterior?
This vertical plan divides the body into right and left portions
What is sagittal plane?
Fluid surrounds a lung but not the heart. Name the thoracic subdivision involved.
What is a pleural cavity?
The arms and legs belong to this major body region
What is the appendicular region?
A membrane allows oxygen to pass easily bus requires a protein channel for many polar molecules. This property controls what enters and leaves.
What is selective permeability?
The heart lies closer to the midline than the lungs. State the heart's position relative to the lungs.
What is medial?
A brain image shows equal right and left halves. Name the specific plan.
What is the midsagittal or median plane?
This cavity subdivision contains the stomach, liver, spleen, and most of the intestines.
What is the abdominal cavity?
This organ system collects sensory information and coordinates a rapid withdrawal reflex.
What is the nervous system?
A rise in body temperature triggers sweating, which lowers temperature toward the set point. Name the type of feedback.
What is negative feedback?
A shoulder injury is closer to the limb's attachment than an elbow injury. State the correct term.
What is proximal?
A scan separates the anterior chest from the posterior back. Name the plane.
What is the frontal or coronal plane?
After a car accident, the ER team checks the brain and spinal cord. Name the two dorsal-cavity subdivisions that contain these organs.
What are the cranial and vertebral cavities?
The lungs exchange gases, while this system transports those gases between the lungs and body cells.
What is the cardiovascular system or circulatory system?
Insulin activates liver and muscle cells but not every cell because only its target cells possess this matching structure.
What is an insulin receptor or matching receptor protein?
A puncture reaches muscle beneath the skin. State the muscle's position relative to the skin.
What is deep?
A horizontal CT cross section separates structures above the image from those below it.
What is a transverse plane?
The patient has a punctured right lung, a lacerated spleen, and an injured urinary bladder. name the three cavities involved in that order.
What are the right pleural (thoracic), abdominal, and pelvic cavities?
Kidney failure disrupts blood filtration, waste removal, and water balance in this system.
What is the urinary system?
