Body Foundations
A medical assistant studies the physical location and shape of the kidneys before assisting with a procedure. Which field is being applied?
Anatomy
A provider documents an injury on the back surface of the patient's leg. Which directional term should be used
Posterior
A cellular structure acts as a selective barrier and regulates which substances enter and leave the cell.
Plasma membrane
A substance moves from an area where it is highly concentrated to an area where its concentration is lower without requiring cellular energy.
Diffusion
This major tissue type covers body surfaces and lines many organs and cavities.
Epithelial tissue
A medical assistant is learning how the kidneys filter blood and form urine. Which field is being studied?
Physiology
The patient's mouth is located below the nose. Which directional term describes the mouth in relation to the nose?
Inferior
A cell requires large amounts of usable energy to perform its functions. Which organelle produces most of its ATP?
Mitochondria
Water moves through a selectively permeable membrane because the concentration of water differs on the two sides.
Osmosis
Bone, cartilage, blood, and adipose tissue all belong to this major tissue category.
Connective tissue
A group of similar cells performs a common function. Which level of body organization has been formed?
Tissue
The patient's thumb is farther away from the body's midline than the little finger when the body is in anatomic position. Which directional term applies
Lateral
A cell is rapidly producing proteins. Which cellular structures are directly responsible for assembling those proteins?
Ribosomes
A substance is moved from a lower concentration to a higher concentration, requiring the cell to use ATP.
Active Transport
A patient's skin is healing after an abrasion. Which cellular division process produces replacement body cells?
Mitosis
Several different tissues work together to form the stomach. Which level of organization does the stomach represent?
Organ
The shoulder is closer to the point where the upper extremity attaches to the trunk than the wrist. Which term describes the shoulder?
Proximal
Proteins produced within a cell must be modified, packaged, and prepared for transport. Which organelle performs this function?
Golgi Apparatus
A red blood cell is placed into a solution and begins to swell because water enters the cell. How should the surrounding solution be classified?
Hypotonic
During cell division, chromosomes have moved to opposite ends of the cell and two new nuclei begin forming. Which mitotic stage is occurring?
Telophase
A patient inhales oxygen through the respiratory system. Which system is primarily responsible for delivering that oxygen to cells throughout the body?
Cardiovascular (Circulatory) System
An imaging study divides a patient's body into right and left portions. Which anatomical plane was used
Sagittal Plane
Damage occurs to the organelle containing the cell's chromosomes and genetic information. Which structure has been damaged?
Nucleus
A patient's body temperature rises. The body begins sweating and increasing heat loss until temperature returns toward its normal range. What regulatory mechanism is being demonstrated?
Negative Feedback
A membrane lines a movable joint such as the knee and helps reduce friction between the joint surfaces.
Synovial membrane
