Physiological Processes Quiz

Physiological Processes and Conditions

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

Digestive System

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

Respiratory System

• 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.

Hematological

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

Systemic Processes (continued)

• 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.

Cellular Processes

• 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.

Other Concepts

• 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.

Test your knowledge on various physiological processes and conditions related to the digestive and respiratory systems, as well as hematological factors. This quiz includes true/false statements to challenge your understanding of key concepts in human physiology.
