    Generally, fertilization takes place in [A] the fallopian tube. After ovulation, an egg is released from the ovary and enters the fallopian tube. If sperm are present in the fallopian tube due to recent intercourse, fertilization can occur when a sperm successfully penetrates and fuses with the egg. The fertilized egg, now called a zygote, undergoes cell division as it moves down the fallopian tube toward the uterus. It takes several days for the zygote to reach the uterus, where it implants into the uterine lining and continues to develop into an embryo.

    While the uterus provides the environment for embryo implantation and development, fertilization typically occurs in the fallopian tube, where the egg and sperm meet. The cervix acts as a passage between the vagina and the uterus, and the vagina serves as the entry point for sperm during intercourse.

    The function of ‘Hanle’s loop’ is related to [A] Excretory system. Hanle’s loop, also known as the loop of Henle, is a vital component of the nephron, which is the functional unit of the kidney involved in urine formation. Its primary role is in the process of urine concentration and the reabsorption of water and electrolytes from the filtrate. As filtrate passes through Hanle’s loop, water and ions are selectively reabsorbed or retained based on the body’s hydration needs. This mechanism allows the kidneys to regulate fluid balance and maintain proper electrolyte concentrations in the body.
    While other systems such as the reproductive system, urinary reproductive system, and nervous system perform distinct functions, Hanle’s loop specifically contributes to the excretory system by facilitating urine concentration and water-electrolyte balance within the body.

    The main chemical compound found in human kidney stones is [C] Calcium oxalate. These stones constitute the most prevalent type, forming when calcium combines with oxalate, a substance naturally found in many foods. When urine contains high levels of calcium and oxalate, they can crystallize, aggregating to form solid stones within the kidneys. Calcium oxalate stones vary in size and may cause significant discomfort and complications if they obstruct the urinary tract.

    While other compounds like [A] Uric acid can also contribute to kidney stone formation, calcium oxalate stones are the most common. Although less frequent, stones composed of [B] Calcium carbonate or [D] Calcium sulphate may also occur, but their occurrence is comparatively rare compared to calcium oxalate stones, which are the predominant type encountered in clinical settings.

    Sweating is important for [D] To regulate body temperature. It serves as the body’s primary cooling mechanism during periods of increased heat or physical exertion. Sweat glands release moisture onto the skin’s surface, which then evaporates, drawing heat away from the body and lowering its temperature. This physiological process helps prevent overheating and maintains a stable internal body temperature, crucial for the proper functioning of various bodily systems.

    While sweating can indirectly contribute to [A] reducing body odor by flushing out bacteria and toxins from the skin, and [C] potentially aiding in opening skin pores by clearing out debris, its primary function remains thermoregulation. Through sweating, the body efficiently manages heat dissipation, ensuring optimal performance and overall well-being, particularly during exercise or exposure to high temperatures.

    Dialysis is used to complete the function of [D] Kidneys. It is a medical procedure employed when the kidneys are unable to adequately perform their vital roles of filtering waste products, excess salts, and fluids from the blood. By mimicking the natural filtration process of the kidneys, dialysis helps maintain the body’s balance of electrolytes and fluids. During dialysis, blood is circulated through a machine that contains a semi-permeable membrane. This membrane allows waste products and excess fluids to pass through, cleansing the blood. The purified blood is then returned to the body.
    While other organs like the lungs, heart, and liver play crucial roles in maintaining overall bodily functions, dialysis specifically addresses the impaired kidney function by providing artificial filtration. Therefore, dialysis completes the function of the kidneys, ensuring essential waste removal and maintaining proper fluid and electrolyte balance in the body.
