Gastrointestinal System


If I were to explain the gastrointestinal system it is the system by which ingested food is acted upon by physical and chemical means to provide the body with nutrients it can absorb and to excrete waste products; in mammals the system includes the alimentary canal extending from the mouth to the anus, and the hormones and enzymes assisting in digestion.

Lymphatic System


If I were to explain the lymphatic system it is the vertebrates is a network of conduits that carry a clear fluid called lymph. It also includes the through which the lymph travels. Lymphoid tissue is found in many organs, particularly the lymph nodes, and in the lymphoid follicles associated with the digestive system such as the tonsils. The system also includes all the structures dedicated to the circulation and production of lymphocytes, which includes the spleen, thymus, bone marrow and the lymphoid tissue associated with the digestive system.

Respiratory System


If I were to explain the respiratory system it is the function is to allow oxygen exchange through all parts of the body. The space between the alveoli and the capillaries, the anatomy or structure of the exchange system, and the precise physiological uses of the exchanged gases vary depending on organism. In humans and other mammals, for example, the anatomical features of the respiratory system include airways, lungs, and the respiratory. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood. This exchange process occurs in the alveolar region of the lungs.

Cardio Vascular

I have learned that this system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system which distributes lymph.

I will summarize this chapter and understand it. And i will explain it to other students.

Allen was not able to report his topic. So sir gregg reported his topic.
Sir gregg discuss it to us very clearly.

Diffrent Senses

I have learned that this article is about the empirical or natural senses of living organisms (vision, taste, etc.).

Senses are the physiological methods of perception. The senses and their operation, classification, and theory are overlapping topics studied by a variety of fields, most notably neuroscience, cognitive science, and philosophy of perception. The nervous system has a specific sensory system, or organ, dedicated to each sense.

I will summarize the chapter before i discuss it to other students.

I was the reporter. NOTHING!!

Endocrine

I have learned that endocrine system is a system of glands, each of which secretes a type of hormone to regulate the body.

The field of study that deals with disorders of endocrine glands is endocrinology, a branch of the wider field of internal medicine. The endocrine system is an information signal system much like the nervous system. Hormones regulate many functions of an organism, including mood, growth and development, tissue function, and metabolism.

I will first summarize the chapter of endocrine system. And explain it to other student clearly.

Sir gregg, expalin it well to us and we understand it very clearly.
