Q1. MCQ Answers (7 x 1 = 7 Marks)

---

Q2. Long Answer - Choose ONE (1 x 10 = 10 Marks)

Option (i): Mechanism of Urine Formation

• Occurs at the glomerulus (tuft of capillaries) inside Bowman's capsule
• Blood pressure drives fluid from glomerular capillaries into Bowman's capsule
• Glomerular Filtration Rate (GFR) = ~125 mL/min = ~180 L/day
• Filtrate contains water, glucose, amino acids, urea, creatinine, ions - NO large proteins or cells
• Driving force: Net filtration pressure = hydrostatic pressure - (oncotic pressure + capsule pressure)

• ~99% of filtrate is reabsorbed back into blood
• Proximal Convoluted Tubule (PCT): reabsorbs ~65% of Na+, water, all glucose, amino acids, bicarbonate (active transport + osmosis)
• Loop of Henle: concentrates urine; descending limb - permeable to water; ascending limb - active NaCl reabsorption (impermeable to water) - creates concentration gradient in medulla
• Distal Convoluted Tubule (DCT): Na+ reabsorption regulated by Aldosterone; water reabsorption by ADH
• Collecting duct: final water reabsorption controlled by ADH (antidiuretic hormone)

• Substances move from peritubular capillaries INTO the tubular lumen
• Secreted: H+ ions (acid-base balance), K+ ions, NH3, drugs, creatinine
• Helps regulate blood pH

• Volume: ~1.5 L/day
• Contains: urea, creatinine, uric acid, excess salts, water
• Urine flows: renal pelvis → ureter → bladder → urethra

---

Option (ii): Blood Pressure - Definition + Factors Regulating

• Systolic BP (SBP): Pressure during ventricular contraction
• Diastolic BP (DBP): Pressure during ventricular relaxation
• Mean Arterial Pressure (MAP): DBP + 1/3 pulse pressure ≈ ~93 mmHg

• Determined by heart rate x stroke volume
• Stroke volume affected by: preload, contractility, afterload
• β-adrenergic stimulation increases HR and contractility

• Regulated at the level of arterioles
• Vasoconstrictors: angiotensin II, catecholamines (noradrenaline), endothelin
• Vasodilators: nitric oxide (NO), kinins, prostaglandins, histamine

• Low BP → juxtaglomerular cells release Renin
• Renin converts angiotensinogen → Angiotensin I
• ACE converts Angiotensin I → Angiotensin II
• Angiotensin II: powerful vasoconstrictor + stimulates Aldosterone release
• Aldosterone: increases Na+ and water retention → increases blood volume → increases BP

• More blood volume = more preload = higher CO = higher BP
• Controlled by: aldosterone (Na+ retention), ADH (water retention), ANP (atrial natriuretic peptide - promotes Na+ excretion when BP too high)

• Baroreceptors (in carotid sinus and aortic arch) detect stretch → signal to vasomotor center in medulla
• High BP → parasympathetic activation (vagus) → decreased HR + vasodilation
• Low BP → sympathetic activation → increased HR + vasoconstriction

• Vasopressin (ADH): vasoconstriction + water retention
• Atrial Natriuretic Peptide (ANP): vasodilation + Na+ excretion (decreases BP)

---

Q3. Short Answer - Attempt Any THREE (3 x 5 = 15 Marks)

(i) Functions of the Placenta

• Immunoglobulins (IgG): pinocytosis (passive immunity to fetus)
• Waste products (urea, bilirubin): fetus→mother by diffusion
• Mechanisms: simple diffusion, facilitated diffusion, active transport, pinocytosis

• hCG (Human Chorionic Gonadotropin): maintains corpus luteum in early pregnancy, basis of pregnancy test
• hPL (Human Placental Lactogen): alters maternal metabolism, promotes fetal growth
• Progesterone: maintains uterine lining, prevents contractions
• Estrogen: uterine growth, breast development
• Relaxin: loosens pelvic ligaments for birth

• Synthesizes glycogen, cholesterol, fatty acids in early pregnancy as energy source for embryo

• Prevents some harmful substances and microorganisms from reaching fetus
• However: not absolute - alcohol, certain drugs, rubella virus, syphilis, and some medications can cross

• Fetal metabolic waste (urea, CO2, bilirubin) excreted into maternal circulation

---

(ii) Refractive Errors of the Eye

• Light focuses in FRONT of retina
• Cause: eyeball too long OR cornea/lens too curved
• Can see near objects clearly; distant objects blurry
• Correction: Concave (diverging) lens

• Light focuses BEHIND the retina
• Cause: eyeball too short OR lens too flat
• Can see far objects; near objects blurry
• Correction: Convex (converging) lens

• Uneven curvature of cornea or lens - different focal points in different planes
• Objects appear blurry/distorted at all distances
• Correction: Cylindrical lens

• Age-related loss of lens elasticity (after age 40)
• Cannot accommodate (focus on near objects)
• Correction: Reading glasses (convex lens)

• Absence of lens (post cataract surgery)
• Corrected by thick convex lens or intraocular lens implant

---

(iii) Functions of the Hypothalamus

• Posterior hypothalamus: activates sympathetic ("fight or flight") responses - increases HR, BP, pupil dilation
• Anterior hypothalamus: activates parasympathetic responses

• Anterior hypothalamus: responds to heat - promotes sweating, vasodilation (heat loss)
• Posterior hypothalamus: responds to cold - promotes shivering, vasoconstriction (heat conservation)
• Fever: pyrogens raise hypothalamic set point

• Lateral hypothalamus: hunger center (lesion → starvation)
• Ventromedial nucleus: satiety center (lesion → obesity)

• Lateral hypothalamus: thirst center
• Controls ADH (vasopressin) release from posterior pituitary to regulate water reabsorption

• Releases releasing and inhibiting hormones:
  • GnRH, TRH, CRH, GHRH, Somatostatin, Dopamine
• Controls anterior pituitary (master gland) → controls thyroid, adrenals, gonads, growth

• Suprachiasmatic nucleus (SCN) - biological clock, regulates sleep-wake cycle

• Involved in rage, fear, sexual behavior

• Produced in hypothalamus, stored and released from posterior pituitary

2. INTRODUCTION TO COMPUTER

Definition

Characteristics of Computer

• Speed - processes millions of instructions per second
• Accuracy - no errors if input is correct ("GIGO" - Garbage In, Garbage Out)
• Storage - stores large volumes of data
• Versatility - performs many types of tasks
• Automation - works without human intervention once programmed
• Diligence - no fatigue, works 24/7

Types of Computers

Basic Components

• CPU (Central Processing Unit) - brain; has ALU + Control Unit
• Input devices - keyboard, mouse, scanner, barcode reader
• Output devices - monitor, printer, speaker
• Storage - RAM, ROM, hard disk, USB drive

---

3. RAM vs ROM (Hardware - Memory)

RAM - Random Access Memory

• Volatile = data LOST when power is switched off
• Temporary working memory
• Stores programs and data currently in use
• Example: when you open a patient file on screen, it is in RAM
• Can be read AND written

ROM - Read Only Memory

• Non-volatile = data is PERMANENT, not lost when power off
• Stores boot/startup instructions (BIOS)
• Cannot be changed by the user
• Example: instructions that start the computer
