TEAS Review Flashcards

Osteoporosis

• Caused by a decline in osteoblast activity, leading to weakened bone density.

Catalysis

• A catalyst accelerates chemical reactions, allowing them to complete in a shorter time frame.

Urea Production

• Urea forms from the breakdown of amino acids in the liver, playing a crucial role in nitrogen excretion.

Circulatory System Functions

• One primary function is to transport hormones throughout the body.

Scientific Revisions

• Scientists depend on peer review to receive critical feedback for refining scientific explanations.

Chemical Reaction

• The reaction of calcium and sulfuric acid produces calcium sulfate.

Parasitic Worms

• A hypothesis suggests that worm infestations can reduce the severity of some autoimmune disorders.

Enzyme Digestion

• Proteases are enzymes capable of digesting proteins.

Genetic Information

• The genetic information delineating an organism's traits is located within the nuclei of its cells.

Skin Color

• The stratum basale layer of the epidermis is responsible for determining skin color.

Calcitonin Release

• The release of calcitonin from the thyroid gland promotes the building of bone tissue.

DNA Bonding

• Hydrogen bonds link nucleotide base pairs within the double-stranded structure of DNA.

Sweat Gland Excretion

• Urea is excreted by sweat glands as a response to protein breakdown and ammonia formation.

Amylase Release

• Salivary glands are responsible for releasing the enzyme amylase, aiding in carbohydrate digestion.

Ribosome Functions

• An inability to produce encoded proteins while copying genetic information indicates a potential issue with ribosomes.

Insulin Secretion

• The pancreas secretes insulin, which is vital for regulating blood glucose levels.

Connective Structure

• The cervix connects the uterus to the vagina, playing a key role in the reproductive system.

Osmosis

• Osmosis is the movement of water through aquaporins in a hypertonic solution, influencing cell volume.

Blood Glucose Regulation

• Insulin, secreted by B cells, is responsible for lowering blood glucose levels.

Steroid Hormone Production

• Cholesterol serves as the organic compound necessary for the synthesis of steroid hormones in the body.

Myelin Function

• Myelin is the insulating sheath that allows for rapid transmission of action potentials along the axon.

Boron Electrons

• A boron atom with an atomic number of 5 and a mass number of 11 contains 5 electrons.

Graduated Cylinder Measurement

• Measurement from a graduated cylinder shows a volume of 38 units.

Basal Shape of Cells

• Flagella serve as a basal shape structure, enabling movement.

Nervous System Parts

• The two major components of the nervous system are the Peripheral and Central nervous systems.

Gas Exchange

• Gas exchange occurs in the alveoli, where oxygen and carbon dioxide are exchanged.

Bone Repair Process

• The process of bone repair follows this order: hematoma, fibrocartilage callus, bony callus, and remodeling.

Diaphragm Function

• Contraction of the diaphragm increases the volume of the thoracic cavity, facilitating inhalation.

Male Gland Function

• The bulbourethral gland secretes fluid into the urethra to neutralize acidity.

Neuron Function

• Neurons transmit sensory information throughout the nervous system.

Fertilization Site

• Fertilization of the egg typically occurs in the fallopian tube.

Vitamin D Production

• The body synthesizes vitamin D when exposed to sunlight, essential for bone health.

Red Blood Cell Production

• Red blood cells are produced in the bone marrow, crucial for oxygen transport.

Tubular Reabsorption

• During tubular reabsorption, useful materials are reabsorbed back into the bloodstream.

Long Bone Example

• The femur is a classic example of a long bone in the human body.

Pulmonary System Components

• The pulmonary vein is a significant part of the pulmonary system, transporting oxygenated blood to the heart.
