Reproductive System

Reproductive System

hCG is secreted primarily by:

Correct option is B, Placenta. In Reproductive System, the accurate description is Placenta, and that is what you should commit to memory. Keep the definition tight and the role clear — the functional job described in the stem is exactly what Placenta does in Reproductive System. Then Placenta is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Placenta. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.

Reproductive System

Hormone responsible for maintenance of pregnancy in early stages is:

Progesterone (A) is the right choice. This sits at the heart of Reproductive System: the wording points straight to what is happening in the tissue or organ system. A useful study habit is to ask what the structure or process is for: Progesterone is the option that correctly names the structure, process, or principle asked for in Reproductive System. That reasoning supports Progesterone. One solid sentence about why this works is enough for recall — you do not need a long essay for every MCQ. When you practise, cover the choices first, write Progesterone from memory, then reveal the letter — that habit builds real recall for Reproductive System.

LH surge is responsible for:

Pick B: Ovulation. Thinking about Reproductive System in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: Ovulation is the option that correctly names the structure, process, or principle asked for in Reproductive System. Hence Ovulation is correct. Treat this as a building block for the rest of Reproductive System; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Ovulation.

Ovulation in humans is best described as:

Answer: C) Spontaneous ovulation. For Reproductive System, once you lock onto the key mechanism or definition, Spontaneous ovulation is the clear fit. If you restate the concept in your own words, Spontaneous ovulation is the option that correctly names the structure, process, or principle asked for in Reproductive System. So Spontaneous ovulation is the clean, accurate selection. If a similar stem appears later, start from the same core fact and you will land on the same kind of answer. In class notes, highlight this same phrase next to the related diagram so the wording and the picture reinforce each other.

Primary oocytes are arrested in which stage?

Correct option is B, Prophase I. In Reproductive System, the accurate description is Prophase I, and that is what you should commit to memory. Keep the definition tight and the role clear — Prophase I is the option that correctly names the structure, process, or principle asked for in Reproductive System. Then Prophase I is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Prophase I.

Oogenesis differs from spermatogenesis because it produces:

Correct option is B, One functional gamete. In Reproductive System, the accurate description is One functional gamete, and that is what you should commit to memory. Keep the definition tight and the role clear — cause and effect line up with One functional gamete — that is the mechanism or reason the stem is pointing to. Then One functional gamete is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto One functional gamete.

Which ovarian follicle is released during ovulation?

Mature Graafian follicle (C) is the right choice. This sits at the heart of Reproductive System: the wording points straight to what is happening in the tissue or organ system.
