1In Class 12 vocational health care theory, which system is primarily responsible for gas exchange between air and blood?
A.Digestive system only
B.Respiratory system (lungs and airways)
C.Skeletal system only
D.Integumentary system only
Explanation: The respiratory system moves air into the lungs and exchanges oxygen and carbon dioxide across alveolar membranes into/from blood. Digestion, bone, and skin support life but do not perform pulmonary gas exchange.
2Which chamber of the heart receives oxygenated blood from the pulmonary veins?
A.Right atrium
B.Right ventricle
C.Left atrium
D.Right ventricle via the aorta
Explanation: Pulmonary veins return oxygen-rich blood from the lungs to the left atrium. The left ventricle then pumps that blood into the systemic circulation via the aorta. The right side handles deoxygenated blood.
3Which blood component is primarily responsible for clotting after vessel injury?
A.Mature erythrocytes only
B.Plasma albumin alone
C.Lymphocytes only
D.Platelets (thrombocytes)
Explanation: Platelets adhere and aggregate at injury sites and help form a haemostatic plug as part of clotting. Red cells mainly carry oxygen; albumin maintains osmotic pressure; lymphocytes are immune cells.
4The functional units of the kidney that filter blood and form urine are called:
A.Alveoli
B.Nephrons
C.Neurons
D.Hepatocytes
Explanation: Nephrons are the microscopic filtering units of the kidney. Alveoli are lung air sacs; neurons are nerve cells; hepatocytes are liver cells.
5Which statement best describes the role of insulin in normal physiology?
A.It raises blood glucose by breaking down glycogen only in muscle for storage as fat
B.It is a digestive enzyme that digests starch in the mouth
C.It helps lower blood glucose by promoting cellular uptake and storage of glucose
D.It is produced only by the adrenal medulla to raise heart rate
Explanation: Insulin, produced by pancreatic beta cells, promotes glucose uptake into cells and storage as glycogen, lowering blood glucose. It is not a salivary enzyme and is not an adrenal medullary catecholamine.
6Homeostasis in healthcare theory most accurately means:
A.The body maintaining relatively stable internal conditions despite external changes
B.Complete absence of any physiological variation at all times
C.Only the ability to increase body temperature without limit
D.A legal document signed on hospital admission
Explanation: Homeostasis is the maintenance of relatively stable internal conditions (e.g., temperature, fluid balance, pH) through regulatory mechanisms. It allows controlled variation, not absolute rigidity, and is a physiological concept—not a consent form.
7Which structure is the main site of nutrient absorption in the digestive tract?
A.Oesophagus
B.Large intestine only
C.Gall bladder lumen
D.Small intestine (especially jejunum/ileum regions)
Explanation: Most nutrient absorption occurs in the small intestine, whose large surface area (villi/microvilli) supports transfer into blood and lymph. The oesophagus mainly transports; the large intestine mainly absorbs water and electrolytes; the gall bladder stores bile.
8Voluntary skeletal muscle differs from cardiac muscle mainly because skeletal muscle:
A.Is found only in the walls of the heart chambers
B.Contracts only under hormonal control with no nerve supply
C.Is under conscious control and is attached to the skeleton for movement
D.Cannot fatigue and never needs rest
Explanation: Skeletal muscle is voluntary, innervated by somatic motor nerves, and moves bones at joints. Cardiac muscle is involuntary and forms the heart wall; both muscle types can fatigue under extreme demand.
9The central nervous system (CNS) consists of:
A.Only peripheral nerves of the limbs
B.Brain and spinal cord
C.Only sensory receptors in the skin
D.Only the autonomic ganglia outside the skull
Explanation: The CNS comprises the brain and spinal cord. Peripheral nerves, receptors, and many autonomic ganglia belong to the peripheral nervous system (PNS).
10Which cells mainly carry oxygen bound to haemoglobin?
A.Erythrocytes (red blood cells)
B.Leukocytes
C.Platelets only
D.Plasma cells only
Explanation: Mature red blood cells contain haemoglobin that binds oxygen for transport. Leukocytes defend against infection; platelets aid clotting; plasma cells produce antibodies.
