Both corpus luteum and macula lutea are
Show Hint
The region in the eye responsible for the center and detailed vision is the macula lutea region of the retina. This region has several cones. During the woman's menstrual cycle, the prominent phases are the follicular phase and the postovulatory or luteal phase. The corpus luteum forms inside the ovary during this time.
- found in human ovaries
- a source of hormones
- characterized by a yellow colour
- contributory in maintaining pregnancy
The Correct Option is C
Solution and Explanation
Both corpus luteum and macula lutea are characterized by a yellow colour.
In the human anatomy, the macula lutea is a tiny yellowish spot of the retina that facilitates central vision near the optic disc of the retina. In the ovaries, the Corpus luteum is made up of follicles that house mature eggs. Yellow lutein is found in both the corpus luteum and the macula lutea. It appears as a yellow spot on the skin. Once the egg is released from the ovary, the cells that line the ovarian follicle change shape and colour to become a corpus luteum (yellow body). Lutein, zeaxanthin, \(\alpha\)-carotene and \(\beta\)-cryptoxanthin are responsible for its yellow colouration.

Concepts Used:
Human Reproduction
Reproduction in human beings involves the fusion of male and female gametes that produces in their reproductive system.
Male Reproductive System:
The male reproductive system comprises:
- Testicles (testes): A pair of oval-shaped organs masked in a pouch known as the scrotum. They manage the production of sperms and the male hormone testosterone.
- Scrotum: It is a sac-like organ that hangs under the penis and behind it. It is the house of the testes, or testicles, and maintains a temperature that is needed for the production of sperm by it.
- Vas deferens: The sperms produced in testes are stored in a tube known as the epididymis. Here the sperms get matured and pass to the urethra via the muscular tube known as vas deferens.
- Accessory glands: This includes three glands, namely the prostate gland, seminal vesicles, and Cowper’s gland. The secretions from the mentioned three glands mix to form a fluid known as semen. Semen nourishes the sperm, raises the volume, and helps in lubrication.
- Penis: The penis is a cylindrical tube that serves as both an excretory organ, and a reproductive organ. It transfers sperms into the vagina during sexual intercourse.
Female Reproductive System:
The female reproductive system is active before, during, and after fertilization as well. It comprises the following parts:
- A pair of ovaries: A pair of ovaries produce and stores ovum in them. They also produce a female hormone known to be estrogen.
- Fallopian tubes (Oviducts): They are the area of fertilization. They connect both the ovaries with the uterus.
- Uterus: Uterus is the place of development for the embryo.
- Vagina: The part that connects the cervix to the external female body parts is called a vagina. It is the passage for the penis during coitus as well as a fetus during transfer.
