In this clip from the BBC’s Natural World: Ant Attack, we see central and east Africa’s powerful dorylus or driver ants hard at work. Watch as construction and ground workers begin to move up to 80 pounds of soil from the base of a fallen tree. It will become their new home in just a few days. Previous soil residents, beware! Plus, note how their sizes vary greatly, dependant on their role in the colony. A few fascinating facts: Seasonally, when food supplies become short, they leave the hill and form marching columns of up to 50,000,000 ants, which are considered a menace to people, though they can be easily avoided; a column can only travel about 20 metres in an hour… Their presence is, conversely, beneficial to certain human communities, such as the Maasai, as they perform a pest prevention service in farming communities, consuming the majority of other crop-pests, from insects to l
How are chemicals or stimuli used in animals as a serpent of instruction? Take some animals like squirrels. What does he experience when he is in a hostile situation? He prepares his body to fight or to flee. Both are very complex tasks that require a lot of energy to control. Many different types of different tissues are used and their aggregated (aggregated) functions come together to function. Like fighting or running, two alternating actions are very different from each other. Thus, here is a condition in which some common preparations are beneficial to the body. These preparations ideally facilitate any action in the near future. How can all this happen?
If the squirrel's anatomy is based solely on electrical impulses through the neurons, the scope of the tissue ready to perform the next action will be limited. On the other hand, if even a chemical signal could be sent, it could reach all the cells of the body and the required changing environment would be enlarged. This function can occur in many animals, including humans, through the adrenaline secretion secreted from the adrenal gland. These organs are located in the body.
The epinephrine is absorbed directly into the bloodstream and reaches various parts of the body. These target organs or specialized tissues, including the heart. As a result, the heart rate increases so that our muscles get more oxygen supply. The availability of blood in the digestive tract and skin is reduced. This is because the muscles around the small arteries contract. This directs the blood towards our skeletal muscles. The contraction of the muscles of the ribs and ribs also increases the respiratory rate. All these responses together prepare the animal body to fight the situation. This animal is part of the endocrine glands which is another way of control as well as coordination in our body.
Plants have endothelium. Which controls growth in a certain direction. What do animal hormones do? In his case we cannot imagine his role for the growth of a particular direction. Sometimes we don't see an animal growing more in one direction based on light or gravity, but, if we think about it more, it will be true that the animal body also grows in carefully controlled places. For example, leaves grow in many places on the body of a plant, but we cannot grow fingers on our face. Our body structure is carefully maintained even during the growth of children.
Here are some examples to help you understand how intuition helps in integrated growth. We have all seen on the salt packet, ‘iodized salt’ and ‘iodine-enriched’ Why do we need to include iodized salt in our diet? Iodine is needed to make thyroxine endothelium in the thyroid gland. Thyroxine regulates the metabolism of carbohydrates, proteins and fats in our body so that it can have an excellent balance for growth. Iodine is indispensable for the synthesis of thyroxine. If we are iodine deficient in our diet then there is a possibility that we may be suffering from goiter. Swelling of the neck is a symptom of this disease.
Sometimes we come in contact with people who are very dwarf (small in size) or overly tall. Have you ever wondered how this happens? Growth Hormone (GI) is a growth hormone secreted by the pituitary gland. As it is named. Growth hormone (GH) regulates the body's growth and development. If this endocrine deficiency occurs in childhood, it causes dwarfism.
By the time you and your friends are 10-12 years old, you may have noticed some amazing changes in their appearance. This change is related to the onset of puberty. This is because testosterone in males and estrogen in females are completely depleted. Do you know anyone in your family or friends who has been advised by a doctor to have low sugar in their diet? Because he is a diabetic. He also takes insulin injections as a treatment. This is an endocrine. Which is produced in the pancreas and which helps in controlling the blood sugar level. If this is not absorbed in the right amount, the blood sugar level rises and causes many harmful effects.
If the right amount of hormones needs to be secreted, it is important to understand the proper mechanism for this to happen. The time and amount of secretion released is controlled by the reaction-based mechanism. For example, if blood sugar levels rise, it causes the pancreatic cells to become aware of it and secrete more insulin in response. When blood sugar levels fall, so does insulin.
