When a human body is stressed an organ named the hypothalamus starts sending signals to the nervous system as well as to the pituitary gland of the body. When the process starts all these elements start to make epinephrine which is commonly known as the stress hormone. This process helps the human body to deal with stress and to run if any dangerous situation occurred. The endocrine system and the nervous system are linked to each other and the hypothalamus is the major element to connect these two organs (Henley, Kaye & Lightman, 2011). The working of the hypothalamus includes the control of pituitary glands, and it regulates the sleep, rest, as well as stress factors of the human body system. When the hypothalamus starts controlling the pituitary glands, it leads to the production and release of the hormone through which the human body reacts in a certain way. The function of the hypothalamus is important in both conditions either sleep or stress factors.
2. Discuss the importance of lymphocytes and describe where they are found in the body. What are some issues or diseases that affect lymphocytes?
Lymphocytes are considered the types of white blood cells, and due to their importance in the human body system, these are significant for the immune system. These can analyze the immune responses, especially to the infectious germs of elements. In adults, the lymphocytes can make more than 40 percent of the human body’s white blood cells. They are available in the circulation system and help to participate in the lymphoid organs and tissues actively. A disease named leukocytosis is one that creates a high number of lymphocytes in the body system. Lymphocytes always respond against infectious diseases and try to decrease their rate if attacked by some infectious disease. Viral infection is also a major reason behind the increased number of lymphocytes in the body (Territo, 2018). When diseases such as bacterial diseases attacked the human body system, then it leads to a higher rate of lymphocytes.
3. What are the roles of the various components of the digestive system? How are ingested materials moved through the digestive tract?
There are several components of the digestive system including the esophagus, stomach, gallbladder, small and large intestine, rectum, and anus. The esophagus is present in the human throat, and its responsibility is to deliver the food to the human stomach. The human stomach is the food processor of the human body, and its tasks included breaking down food into small parts and processing them. The component of the gallbladder can store the bile, and after its processing measures, it releases it to the duodenum to help the fats to digest effectively. The rectum is like a small chamber in which the colon connects with the anus. It can provide the stool to color and shift into the anus. The anus is the ending part of the digestive system through which the waste of the human body is released (“Digestive System | Cleveland Clinic,” n.d).
Through the mouth, the ingested materials move through the digestive tract. It starts digesting the food whenever it entered the human body system.
4. Based on studies what constitutes a balanced diet, and why this is important? Provide a small example of a vegetarian lunch menu that includes all the amino acids necessary for a vegetarian diet.
A balanced diet is a healthy and nutritious food that can maintain the human body system healthily and active. In this pattern, food is eaten by humans in the most appropriate proportions. It helps to maintain healthy body weight and makes the body more active. It is important because it significantly provides a healthy lifestyle. People who want to maintain a perfect weight of the body and want the perfect shape of their body use a balanced diet routine. In this way, people maintain their active and healthy lifestyle. Vegetable smoothies are ones that include amino acids and are filled with proteins that are healthy for the human body. The vegetable smoothies are not only filled with nutrients but also help to add a refreshing taste to the food patterns of humans. Spirulina is a type of vegetable smoothie in which blue, and green microalgae are added with the extract of chia seeds.
