Hormones are chemical molecules produced by endocrine glands. One such endocrine gland is the thyroid gland, which synthesizes t
he thyroid hormone, which in turn affects the heart muscles. Which two statements describe the probable reason for the function of the hormone? 1.The cells in the heart have specific receptors that allow for the intake of hormones.
2.The heart and the endocrine glands have the exact same types of cells.
3.All cells make the same types of hormones.
4.Thyroid hormones show their effect on the heart by means of specialized cells. 5.Thyroid cells and cardiac cells have different DNA.
A hormone is a biologically active chemical substance, synthesized by a glandular cell secreted into the internal environment where it circulates, acting remotely and by blood on receptors specific to a target cell. It transmits a message in chemical form and therefore plays a role of messenger in the body.
The emitting organ thus acts at a distance on all of the target organs of the organism or of neighboring organisms of the same species, or even of symbiotic organisms whose receptors are activated in contact with specific hormones (lasting interactions).
α-type receptors of thyroid hormones (TRα, NR1A1) are widely expressed in all cells but particularly cardiac and skeletal cells.
Tapeworms (Cestoda) are called flatworm (Platyhelminthes) while hookworms are roundworms (Nematodes). Both are parasites and live within the intestines of animals and feed on the nutrients digested in the organ. When these worms migrate to other parts of the body, they cause complications, The more of this parasite one has the heavier the symptoms they will exhibit – such as asthma-like symptoms.
Before the rise of the Mongols in the 13th century, it is now
called central and western Inner Mongolia, particularly the Hetao region,
change back and forth in control between Chinese agriculturalists in the south
and nomadic Mongol of the north. is known through Chinese chronicles and
historians.
