The cell placed within the hypertonic solution will quickly become dehydrated due to the concentration gradients and osmosis.

Though I cannot provide the drawing of the cell, I can describe what a hypertonic solution is and what effect it would have on the cell.

A hypertonic solution is a solution that when compared to another solution or object, has a higher concentration of solute. If made into a drawing, this would look like the cell is in water, but said water contains a large amount of solute, like sugar for example.

Hypertonic solutions can cause water to move. The water moves through a process known as Osmosis, which is the tendency of water to move towards a location that has a higher concentration of solute, in order to dissolve this concentration. Since the liquid inside the cell has a lower concentration of solute than the environment, the water inside the cell will escape through osmosis and can severely dehydrate the cell.

Some substances that were not initially filtered in the glomerulus, but must be eliminated from the blood, become a component of

dolphi86 [110]

Some substances that were not initially filtered in the glomerulus, but must be eliminated from the blood, become a component of urine through the process of urine formation.

Urine: A liquid excrement consisting of water, salts, and urea, which is made in the kidneys then released through the urethra.

The process of urine formation involves 3 major steps:

Filtration:- Blood enters the afferent arteriole during filtration, flowing into the glomerulus where filterable blood components—such as water and nitrogenous waste—move toward the interior of the glomerulus and nonfilterable blood components—such as cells and serum albumins—exit via the efferent arteriole.
Reabsorption: During this, ions and molecules will be returned to the bloodstream. As the fluid's osmolarity (ion concentration) fluctuates, water and ions are eliminated as it moves through the proximal/distal convoluted tubules, the loop of Henle, and the collecting duct.
The process of secretion involves the removal of various substances from the blood into the collecting duct, including hydrogen ions, creatinine, and medications. Urine, the final result of all these procedures, is essentially a collection of chemicals that have not undergone tubular or glomerular reabsorption.

Widespread coagulation and subsequent bleeding from a deficiency of clotting factors occurs in

jeka94

Hello!! Your answer would be Disseminated Intravascular Coagulation (DIC). In some cases of DIC, it can cut off blood supply to your liver, brain, and kidneys when you are cut. In other cases of DIC, you have a high risk of serious bleeding with a big injury or just a small one, you can also bleed spontaneously. I hope I helped and gave you the right answer you were looking for. Have a great night!!

Which hormone is secreted during periods of stress and is related to increased risk of disease?

gulaghasi [49]

Stress is a condition that tends to disturb the equilibrium of the individual with the environment. There are hormonal changes which occur during stress and have their impact in the endocrine system.

Reaction to stress is associated with increased hormone secretions of several hormones such as glucocorticoids, growth hormone, prolactin and catecholamine. The elevated levels of these hormones increase the risk of infections and also decrease the innate immunity as well as increase the autoimmune responses.

There are endocrine disorders related with the increased hormone secretion during stress conditions such as psychosexual dwarfism, obesity, Grave’s disease and gonadal dysfunction. The effect of increased secretion of the hormones is increase in mobilization of energy and adaption of the individual to current circumstances.

Activation of the pituitary adrenal axis is an important and dominant response due to stress. On stimulation of the pituitary adrenal axis results in hypothalamic secretion of the CRF (corticotrophin-releasing factor) which further stimulates the pituitary to ACTH, 3-endorphin and 8-lipotropin.

During stress, the plasma levels of these hormones increase up to five times.

The stimulation of the pituitary adrenal axis is also associated with the release of hormone catecholamine. The increased level of catecholamine leads to increased skeletal muscle flow of blood increased cardiac output and glucose levels, bronchiolar dilation, cutaneous vasoconstriction etc.

Acute stress releases vasopressin rapidly from the Para ventricular nucleus of hypothalamus together with corticotrophin releasing hormone.

During stress there is also suppression of gonadotropins and gonadal steroidal hormones which disrupt the normal menstrual cycle and prolonged stress can also lead to impairment of reproductive functions.

Thyroid functions are down regulated during stress conditions. T3 and T4 levels decrease whenever there is any stress condition.

The growth hormone level increases due to physical stress and prolactin level may increase or decrease depending on the conditions of regulatory environment locally.
