Who may apply through the 2026 direct route?

The signed UCAD notice addresses Senegalese candidates with a baccalauréat in series L or S or an accepted equivalent, with the required identity, diploma and recent medical documents. It does not state an age ceiling. Professional applicants have a separate route; do not copy its service requirements into the direct route.

Does this bank reproduce the official examination?

No. These are independent English-language MCQs, not an official translation or format simulation. Current detailed paper rules and permitted response languages should be confirmed with ENDSS. Practice French essay writing and complete written science or mathematics problems separately.

Does the question mix follow official percentages?

No current detailed blueprint was found. The 2019 notice gave equal coefficients to the essay and the chosen scientific paper, but this small bank is a partial study resource, not a proportional mock exam or complete mathematics/SVT syllabus.

1Which heart chamber ejects oxygenated blood through the aortic valve into the systemic circulation?

A.Right atrium

B.Left ventricle

C.Left atrium

D.Right ventricle

Explanation: The left ventricle generates the pressure that drives blood through the aorta to the body. The pulmonary circulation instead begins at the right ventricle.

2During an acute threat, a person's heart rate rises and the bronchioles dilate. Which division of the autonomic nervous system most directly coordinates these responses?

A.Parasympathetic division

B.Enteric division

C.Sympathetic division

D.Somatic motor division

Explanation: Sympathetic activation prepares the body for increased activity, including increased heart rate and bronchodilation. These involuntary responses differ from somatic control of skeletal muscle.

3Which endocrine tissue contains the cells that secrete insulin and glucagon?

A.Adrenal cortex

B.Thyroid follicles

C.Anterior pituitary

D.Pancreatic islets

Explanation: Pancreatic islets contain insulin-secreting beta cells and glucagon-secreting alpha cells. Their complementary actions help regulate blood glucose.

4A diagram shows a renal corpuscle followed by a proximal tubule, loop and distal tubule. Which functional unit is represented?

A.Nephron

B.Renal pelvis

C.Ureter

D.Renal calyx

Explanation: The nephron combines filtration at the renal corpuscle with selective reabsorption and secretion along its tubule. Collecting ducts subsequently receive fluid from multiple nephrons.

5For the essay prompt 'Informer suffit-il à améliorer la santé ?', which plan best addresses the question rather than merely listing health messages?

A.Describe three communication media without considering their effects

B.Explain information's contribution, examine barriers to action, and evaluate complementary measures

C.List diseases in alphabetical order and end with a prevention slogan

D.Assume information always changes behavior and give only confirming examples

Explanation: The question asks whether information is sufficient, so a good discussion evaluates both its value and its limits. Access, resources and social conditions can be examined before reaching a reasoned conclusion.

6In a concentration calculation, a liquid contains 250 mg of a dissolved substance per 5 mL. What volume contains 500 mg?

A.2.5 mL

B.5 mL

C.10 mL

D.15 mL

Explanation: The concentration is 250 / 5 = 50 mg/mL. The required volume is 500 / 50 = 10 mL.

7In a dissertation, what is the main purpose of the conclusion?

A.Introduce a major argument that the body has not examined

B.Repeat the introduction without incorporating the discussion

C.Present a new collection of unrelated examples

D.Synthesize the reasoning and give a justified answer to the problem

Explanation: A conclusion brings the developed reasoning together and answers the problem posed. Any broader perspective should follow from that reasoning rather than replace it.

8Reduced renal perfusion stimulates release of which enzyme that starts the conversion of circulating angiotensinogen to angiotensin I?

A.Renin

B.Aldosterone

C.Erythropoietin

D.Angiotensin-converting enzyme

Explanation: Renin released by juxtaglomerular cells cleaves angiotensinogen to form angiotensin I. Angiotensin-converting enzyme acts at the next major step, producing angiotensin II.

9Which example illustrates natural passive immunity?

A.Producing antibodies after vaccination

B.Receiving maternal IgG across the placenta

C.Developing immune memory after infection

D.Receiving an injected antibody preparation

Explanation: Placental transfer supplies the fetus with antibodies made by the mother, so the protection is passive. It occurs naturally rather than through a medical administration of antibodies.

10An actively respiring tissue becomes more acidic while oxygen pressure is held constant. How does the Bohr effect help that tissue obtain oxygen?

A.Acidity increases hemoglobin's oxygen affinity and reduces unloading

B.Acidity prevents oxygen from dissociating from heme

C.Acidity reduces hemoglobin's oxygen affinity and favors unloading

D.Acidity converts hemoglobin directly into dissolved oxygen

Explanation: An increase in hydrogen-ion concentration reduces hemoglobin's affinity for oxygen, shifting the dissociation curve to the right. This promotes oxygen release at a given oxygen partial pressure.
