Physiological Processes Quiz

Study Notes

Put (v) Or (X): A series of statements about physiological processes, each followed by a true/false answer choice.

HCl and Pepsinogen: Hydrochloric acid (HCl) in the stomach activates pepsinogen into pepsin.
Salivary Amylase and Proteins: Salivary amylase does not digest proteins.

Hypoxia: Hypoxia is a deficiency of oxygen at the tissue level.
Tachycardia: Tachycardia is an increase in heart rate, not a decrease.
Cyanosis: Cyanosis is characterized by a bluish coloration of the skin and mucous membranes, not a yellowish coloration.

Anemic Hypoxia: Anemic hypoxia is a result of a deficiency in normal hemoglobin.
Ovaries and Testosterone: Ovaries do not secrete testosterone; testes do.

Pneumothorax: Collection of air in the pleural cavity is called pneumothorax.
Nervous System Structure: The reflex arch is not the unit structure of the nervous system. The unit structure is the neuron.
Farsightedness: Farsightedness is called hyperopia.
Macrocytic Anemia: Macrocytic anemia is often linked to deficiencies in folate or vitamin B12, not solely folic.
Expiration: Expiration is a passive process, not an active one.
Plasma Proteins: All plasma proteins are produced by the liver.
Thyroid Hormones: Exposure to cold increases the secretion of thyroxine and adrenaline.
Gonadal Hormones: Testes secrete testosterone, not estrogen and progesterone.
Sympathetic Stimulation: Sympathetic stimulation increases the heart rate.
Pupil Response: The reactive pupil is the pupil that constricts and dilates.
Cardiac Contraction: Cardiac contraction to eject blood is called systole, not diastole.
Gastric HCl Role: Gastric HCl aids in the absorption of iron and calcium.
Red Blood Cells and Anemia: Anemia is a decrease, not an increase, in red blood cells.
Cardiac Output: Cardiac output is the volume of blood pumped by each ventricle per minute.

Cell Membrane: The cell membrane controls cellular activities and division, while the nucleus controls both.
Cellular Energy: Cell energy is generated by the mitochondria.
Polycythemia: Polycythemia is an abnormal increase in the number of red blood cells, not a decrease.

Body Temperature: A constant body temperature means heat gain is equal to heat loss.
Heart Rate (continued): Rhythmicity and automaticity are properties of cardiac muscle.
Digestive Process: HCL in the stomach aids in digesting proteins and fats.
Blood Pressure: Systolic blood pressure is the maximum pressure reached within the arteries.
Blood Type: The blood types are red blood cells, white blood cells, platelets, all created in the bone marrow.
Reflex Arc: The reflex arch is composed of a receptor, afferent neuron, center, efferent neuron, and effector organ.
Types of Hypoxia: Types of hypoxia include hypoxic, stagnant, anemic, and histotoxic hypoxia.
Hemostasis: Hemostasis is the stopping of blood bleeding through vasoconstriction, platelet aggregation, and coagulation.
Cardiac Muscle Properties: Cardiac muscle properties include excitability, contractility, conductivity, and automaticity (rhythmicity).
Ventricular Contraction and Relaxation: Ventricular contraction is called systole, and relaxation is called diastole.
