The accessory digestive system is a big part of the mechanism of the digestive gland because without it the digestive system would not function properly.

A disorder in the endocrine system may lead to hormonal issues. For example, an inbalance in growth hormones can affect growth while thyroid disorders may affect metabolism.

The stomach is an organ in the digestive system that primarily functions to temporarily store food, mixing it with stomach acid and enzymes, and partially breaking it down into a liquid consistency called chyme before releasing it into the small intestine for further digestion and absorption of nutrients; essentially, it is the primary site for mechanical and chemical digestion of food.

An example of an endocrine disorder is hyperthyroidism, also known as an overactive thyroid, which occurs when the thyroid gland produces too much thyroid hormone which controls how the body uses energy. When the thyroid is overactive, the body's metabolism speeds up, which can impact many bodily functions.

Diabetes and hyperthyroidism are disorders that can be caused by endocrine dysfunctions. Diabetes side effects can be excessive thirst, urination and fatigue. For overproduction of pituitary gland thyroxine and side effects can be.unexpected weight loss, irregular heartbeat. Treatments is usually medication.

An example of an endocrine disorder is hypothyroidism, results of which causes fatigue and weight gain. The flip side of this disorder would be increased hair growth, hyperthyroidism, side effects include weight loss, a decrease in hair growth, or even hair loss, and an anxious demeanor. Both of these disorders involve the thyroid.

After this video, I learned that the digestive system is divided into two groups; the alimentary canal and the accessory digestive organs. The mouth is part of the alimentary canal, and it is also where digestion begins. The first step takes place when we are about to put food or drinks in our mouth. This process is called ingestion. After that, some accessory digestive organs such as teeth, tongue, and salivary glands are used to break down starch in the food we eat. They also help to move the food down through the rest of the digestive system.

A dysfunction in the endocrine system can cause some disorders due to high or low levels of growth hormones. For example; to much ACTH may cause crushing disease, to little TSH may cause cretinism in children and myxedema in adults & to much may cause hyperthyroidism, which effects are similar to Graves;' disease, in which antibodies minic TSH.

Adrenal insufficiency, gland that releases cortisol and aldosterone. When these hormones are not properly being released, can potentially cause health problems. Health problems such as Addisons disease. Which causes severe fatigue, stomach upsets, dehydration, and skin breakdown.

Dysfunction in the endocrine system can lead to various disorders, including Diabetes Mellitus, hypothyroidism, hyperthyroidism, Cushing's syndrome, Addison's disease, Polycystic Ovary Syndrome (PCOS), growth hormone deficiency, hyperparathyroidism, hypoparathyroidism, and thyroid nodules or cancer. These conditions arise from imbalances in hormone production or action, affecting many bodily functions and overall health.

The kidneys produce the erythropoietin hormone which stimulates/increases red blood cell formation. If the kidneys are damaged and can't produce enough of this hormone, red blood cell production decreases, leading to anemia.

The growth hormone can be affected when there is a dysfunction in the endocrine system. If there are low levels of growth hormone in children before the closure of the epiphyseal plate, it can lead to dwarfism. In contrast, if there are high levels, or more than normal levels of the growth hormone in children after the closure epiphyseal plate , it can lead to gigantism. What's interesting is that the bones won't just keep growing because that's done when the epiphyseal plate closes. Instead the bones begin to widen. That condition is then called acromegaly. That is something new I learned!

The visceral reflex arc involves two motor neurons, preganglionic neuron and a postganglionic neuron, which affect smooth muscle, cardiac muscle and glands ( non voluntary movements). The somatic reflex arc involves only one motor neuron, which affects the skeletal muscle that voluntary movements.

The most interesting part of this chapter for me was learning about the different types of white blood cells and how they protect the body from infections. I also found it surprising that blood is considered a connective tissue, not just a fluid. Another thing that stood out was how red bone marrow produces new blood cells, while yellow bone marrow mostly stores fat.

I found it interesting to learn about the 5 different types of white blood cells, as they are the cells that function to protect the body from infectious microorganisms and are the only formed element that can function outside of the bloodstream in other tissues.

The most interesting thing in this chapter that stood out to me was the fact that erythrocytes have no organelles or nuclei. For some reason, it feels that for erythrocytes to have such an important job as transporting oxygen and carbon dioxide molecules, they would need to have more "parts" to them.

After watching this video, I learned that there are three main proteins in the blood plasma: Albumin, globulins, fibrinogen. -Albumin helps water from diffusing out of the blood into the extra cellular matrix of tissue -globulins contain antibodies that helps defend the body against infection. They also transport the protein that carry lipids, iron, and copper -Fibrinogen is crucial for blood clotting. It’s converted to fibrin to form a clot when there is bleeding

Before going over this video, I didn’t really think that learning about blood would be that interesting, but I was wrong! Blood is an essential part of our well being, and it plays a bigger role than I thought. One of the things I found interesting was that blood helps us fight infections! The most important cells of the immune system are called lymphocytes. They’re considered the most important because they can recognize and target pathogens. I also learned that blood is a liquid connective tissue. I always thought it would be classified as a cell, not a type of connective tissue.

One thing I found interesting is that Plasma is not considered a "formed element" in the blood. It is the liquid portion of blood, composed mostly of water, proteins, electrolytes, and waste products. Actual formed elements of blood include: Leukocytes (white blood cells), Thrombocytes (platelets), Erythrocytes (red blood cells).

In the visceral reflex arc it is involuntary with how the way our body reacts for things such as hunger, fullness, pain, and nasuea. It can also monitor stretch, temperature, and chemical changes. The somatic reflexes are voluntary, examples would be flexing our muscles and using our muscles for everyday tasks such as walking
