The adrenal gland, or the adrenal gland, and the adrenal gland is a silent gland, which produces what you produce to the bloodstream directly and not through channels, as found in the body of mammals, the color tends to white, and there are two where each of these adrenal glands above Each kidney of the kidneys was also characterized by renal dysfunction,
The adrenal gland is sometimes referred to as adrenaline, which is its main product.
Each gland of these two days consists of: an external part and an internal part, while the outer part is called adrenal cortex, and the inner part is called adrenal pulp. While the adrenal glands on the right are embolized, the left-hand side is crescent shaped, and the diameter of the two adrenal glands is approximately five centimeters.
The primary function of the alcumin is hormone secretion when it responds to stress by catecholamines such as adrenaline, corticosteroids such as cortisol. It also acts as an effect on the kidneys and its functions, so that it releases the hormone aldosterone.
As we mentioned earlier, each of these two adrenal glands consists of an external part of the adrenal cortex and an inner part of the adrenal core.
The outer part consists of three regions, where this part secrete more than forty secretions are made of steroid compounds, and the hormones that are produced mainly remain:
Aldosterone, Cortisol, Androgen, Androsterone, Androstenedione.
The inner part is the secretion of the adrenaline hormone, the hormone adrenalin.
The nerve core stimulates the core of the adrenal gland to produce adrenalin, and adrenalin in the blood, through which the body is given the ability to cope with sudden stress, such as strength and speed Pulses of the heart, lift blood pressure.
On the side of the adrenal cortex, the outer part of the adrenal gland, this cortex secrete a number of hormones, some of which are essential and necessary for life. These cortical hormones belong to three major groups: the mineral cortex, the glycoproteins, the sex hormones.
The functions of adrenal hormones can be summarized as follows:
- Work to increase the heart rate in order to get the increase in pumping blood to the body.
- Increased breathing through which blood gets enough oxygen.
- The conversion of glycogen to glucose leads to an increase in the amount of sugar in the blood.
- Expansion of alopecia in the blood vessels that are in the skin and muscles so that the blood is sufficient.
- The contraction of the capillaries and blood vessels in the intestines, through which high blood pressure Faisal to those who need parts of the emergency.
