RUHS / State Nursing Entrance Zoology Flashcards
50 question-and-answer cards covering Zoology as it is examined in RUHS / State Nursing Entrance. 24 of them are printed below, taken from across the deck — no signup, no paywall on the preview.
24 sample cards from the Zoology deck
Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.
Describe the path of blood through the four chambers of the human heart starting from the right atrium.
Right atrium → right ventricle → lungs → left atrium → left ventricle → aorta/body.
What is the function of the SA node in the heart?
It is the pacemaker, generating the impulse that initiates each heartbeat.
What is the definition of cardiac output and its approximate normal value?
Volume of blood pumped by each ventricle per minute (stroke volume × heart rate); about 5 litres.
What is the structural and functional unit of the kidney?
The nephron.
Name the three main processes involved in urine formation.
Glomerular filtration, tubular reabsorption, and tubular secretion.
What is the chief nitrogenous waste excreted by humans, and what does this make us?
Urea; this makes humans ureotelic.
Which part of the nephron is responsible for concentrating urine via a counter-current mechanism?
The loop of Henle (with the vasa recta).
What are the two main proteins responsible for muscle contraction, and which is thick vs thin?
Myosin (thick filament) and actin (thin filament).
According to the sliding filament theory, what causes muscle contraction?
The actin (thin) filaments slide over the myosin (thick) filaments, shortening the sarcomere.
What type of joint is found at the shoulder and hip, allowing movement in all directions?
Ball and socket joint.
What ion is essential for the release of acetylcholine and for muscle contraction at the sarcomere?
Calcium (Ca2+).
What are the two main divisions of the human nervous system?
The central nervous system (brain and spinal cord) and the peripheral nervous system.
Name the three major regions of the human brain.
Forebrain, midbrain, and hindbrain.
What is a synapse, and what chemicals transmit signals across it?
The junction between two neurons; signals are transmitted by neurotransmitters (e.g., acetylcholine).
Which part of the brain controls balance, posture, and coordination of movement?
The cerebellum.
Which gland is called the 'master gland' and what does it regulate?
The pituitary gland; it regulates other endocrine glands and many body functions.
Which hormone regulates blood sugar by promoting glucose uptake, and which gland secretes it?
Insulin, secreted by the beta cells of the islets of Langerhans in the pancreas.
Name the hormone secreted by the thyroid gland that requires iodine, and a deficiency disorder.
Thyroxine; deficiency causes goitre (or cretinism/hypothyroidism).
What is the site of fertilization in the human female, and where does implantation occur?
Fertilization occurs in the fallopian tube (ampulla); implantation occurs in the uterus wall (endometrium).
State Mendel's Law of Segregation.
During gamete formation, the two alleles of a gene separate so each gamete receives only one allele.
In a monohybrid cross of Tt × Tt, what is the genotypic and phenotypic ratio in the F2 generation?
Genotypic ratio 1:2:1 (TT:Tt:tt); phenotypic ratio 3:1 (dominant:recessive).
What evidence did Charles Darwin use to propose natural selection, and what is its key principle?
Survival of the fittest; organisms best adapted to their environment survive and reproduce.
Name the causative organism of malaria and the vector that transmits it.
Plasmodium (a protozoan), transmitted by the female Anopheles mosquito.
What are the two key enzymes used in genetic engineering for cutting and joining DNA?
Restriction endonucleases (molecular scissors) cut DNA, and DNA ligase joins DNA fragments.
What this deck covers
The Zoology deck follows the RUHS / State Nursing Entrance Zoology syllabus — 4 chapters and 15 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 12.5 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 66 characters, which is long enough to carry the reasoning and short enough to say out loud.
A deck like this earns its keep on the second and third pass. Read the syllabus first so you know the shape of the subject, then use the cards to find the specific facts that have not stuck.
Zoology flashcards FAQ
How many Zoology flashcards are in this RUHS / State Nursing Entrance deck?
50 cards. This page previews 24 of them, sampled evenly across the deck so you can judge the difficulty before installing anything.
Are these RUHS / State Nursing Entrance flashcards free?
Yes. The preview here is free to read with no signup, and the full 50-card deck is free inside the Examius app.
What do the Zoology cards cover?
They follow the RUHS / State Nursing Entrance Zoology syllabus — 4 chapters and 15 topics — so the questions track what is actually examinable.
How should I use these flashcards?
Read the syllabus first so you know the shape of the subject, then drill the deck. Examius schedules each card with spaced repetition, so cards you keep missing come back sooner and ones you know drift further apart.
