    Which glands helps to maintain immunity
    Solution
    Thymosins secreted by thymus  play a major role in the differentiation of T-lymphocytes, which provide cell-mediated immunity. In addition, thymosins also promote production of antibodies to provide humoral immunity.
  • Question 5
    1 / -0
    Hormone of pituitary
    Solution
    Option $$D$$ is correct.
    Follicle stimulating hormone is produced by the pituitary gland. Follicle stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone which is secreted and synthesized by the gonadotropic cells of the anterior pituitary gland.
    The FSH hormone regulates the development, growth, pubertal maturation, and reproductive process of the body.
  • Question 6
    1 / -0
    Growth hormone and thyroxin increase the length of -
    Solution
    A. Bone
    Reason: Growth hormone (secreted from pituitary gland) is the most important factor for the growth of the human body. It increases the length of the bones. On the other hand, Thyroxin (secreted from Thyroid gland) increase the metabolism rate which in turn promotes the growth. 
    So, the correct option is A.
  • Question 7
    1 / -0
    Which of the following hormones coordinate with each other to maintain ideal blood $$Ca$$ level?
    Solution
    • In addition, tetraiodothyronine or thyroxine (T4) and triiodothyronine (T3) Thyroid gland also secretes a protein hormone called thyrocalcitonin. 
    • Thyrocalcitonin(TCT) lowers blood calcium levels. It counters the actions of parathyroid hormone which increases the blood calcium level.
    • The parathyroid glands monitor the calcium in the blood 24 hours per day. The four parathyroid glands make more or less parathyroid hormone (PTH) in response to the level of calcium in the blood. When the calcium in our blood goes too low, the parathyroid glands make more PTH in order to increase the blood calcium levels.
    • Hence Thyrocalcitonin and Parathyroid hormones coordinate with each other to maintain ideal blood Ca level.
    • So, the correct answer is 'Thyrocalcitonin and Parathyroid hormone'.
  • Question 8
    1 / -0
