Blood pressure falls with distance from the heart. Using this information, which of the following properly lists the type of blo
Angelina_Jolie [31]

Answer:

The correct answer will be- arteries→capillaries→veins

Explanation:

The circulation of blood in the closed circulatory system flows through blood vessels. These blood vessels show structural differences in response to the pressure exerted by the blood on the surrounding medium.

The blood pressure varies in the circulatory system because the heart pumps the blood with a greater force, so the blood vessel called arteries which carries the blood from the heart posses thicker walls.

The blood pressure reduces until the blood reaches the organs, the blood pressure reduces. Thus the blood in the capillaries has lower pressure.

When blood exits from the organs back to the heart, then the blood pressure is highly reduced as a result, the veins carry the blood with lower pressure.

Thus, arteries→capillaries→veins are the correct answer.

List tim''s symptoms and identify the organ system (or specific organ) associated with those symptoms. (your may need to referen
pantera1 [17]
1. Tim's symptoms include deteriorated coordination, stamina and school performance, nausea, painful joints and an abnormal increase in growth rate. His personality also changed which manifested as depressive mood, introversion, anxiety and tension. These symptoms could indicate an endocrinological problem, therefore the organ system which could be associated with them is the thyroid gland.

2. The thyroid gland is an organ of the endocrine system which is located in the neck, behind Adam's apple. It regulates metabolism, protein synthesis and development. It does so by producing a number of hormones: calcitonin, thyroxine and triiodothyronine. The two thyroid hormones (thyroxine and triiodothyronine) regulate the body's metabolism by controlling the way cells produce and consume energy.

3. Hyperthyroidism is an endocrine condition in which there is an overproduction of thyroid hormones by the thyroid gland. Under these conditions, the thyroid gland proves to be overactive and the main symptom is the acceleration of the metabolism. Tim's sudden increase of growth rate and inability to gain weight, along with his nervousness and mood swings, and his fatigue and loss of energy could indicate a problem of hyperthyroidism.

4. Cortisol is a steroid hormone which is produced by the thyroid gland. It is often called as the "stress hormone" as it is released in response to a stressful situation. It is also released in response to low blood glucose concentration. Some of cortisol's functions are the increase in blood sugar, the suppression of the immune system and bone formation. Cortisol is also involved in the metabolism of macronutrients.
