Lateef9961: let us tak 4 example,lacteal.
Lacteal is a lymph dat absorb digested fat known as chyle,it also transfer the digested fat 4rm the point of digestn to whr day ar needed

Chyle or Chyme?

[color=green]u guys shld check out these simple questions grin



(1) Which component of
plasma decreases the
water potential of
blood by the greatest
amount?
Me thinks its CARBONDIOXIDE

(2) A parasite which lives in tissue fluid can block lymph capillaries,
cuasing swelling of the
tissues, particularly in
the leg. Explain why
blockage of the lymph
capillaries leads to
swelling in the tissues.

(3) Explain how the lymph system is
involved in the absorption of the
products of digestion.
Hahahaha! Na wa u oh!....
1. In the case of plasma sha , decrease in solute potential, causes decrease in water potential (I don't even know what that means grin but I saw it somewhere once...).
2. If the lymphatic system is blocked by a parasite, the movement of lymph (fluid) becomes restricted and since the lymph cannot move freely anymore it accumulates, causing swelling.
3. Hmm lymphatic system helps to transport digested fat from the intestines to the cells that need it...but to explain it na long tin oh we'll start talking abt osmosis ,diffusion, intercellular fluid...kai!!!!
Guy! Why ur questions dey always be like german? Relax na ask simple biology....

Thyroid gland get parts? Na wa o....I didn't know that...kai

Undersecretion of thyroid gland...in children cretinism...in adults it causes reduced metabolic rate, makes them lethargic and causes a condition known as myxodema (I hope that's the spelling oh)

Oversecretion of thyroid leads to...hyperplastic goitre and exophthalmic goitre depending on what's going on...
Hyperplactic goitre is caused by prolonged stimulation of the thyroid by TSH
While exophthalmic goitre is caused by oversecretion of thyroxine

Na wetin I cram for exam oh....

u got 1 and 2 but 3 over secretion causes exophthalmos(bulging of the tissues behind d eyes) under secretion cause goitre(swollen of the neck) and cretinism in infant.

1. By consist, do you mean the thyroid hormones? If yes; the hormones are triiodothyronine, tetraiodothyronine, and another hormone involved in calcium regulation(cant remember the name).
2. The most important is T3- triiodothyronine.

Abeg sumbody clap for this my guy.
You're on point, the third is Calcitonin. But bro, the number 2 na tetraiodothyronine easily called THYROXINE. Kudos once more.

consist of? Or do u mean secretes and bros thyroid gland is not secreted o.. Rather it secretes hormonesmiley

Anyway, lemme answer to the best of my knowledge

1). It secretes thyroxine, calcitonin and
.................
2)it z thyroxine

3) under secretion of thyroxine cause cretinism and over secretion causes goiter


And bro don stay on the sidelines oo shocked
