lymph and immune system

The lymphatic system in vertebrates is a network of conduits that carry a clear fluid called lymph. It also includes the lymphoid tissue 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.

The immune system is the body's defense against infectious organisms and other invaders. Through a series of steps called the immune response, the immune system attacks organisms and substances that invade body systems and cause disease.
The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. The cells involved are white blood cells, or leukocytes, which come in two basic types that combine to seek out and destroy disease-causing organisms or substances.

- in this i will differentiate so they will know the difference of this two system.

respiratory system

The respiratory system's 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. 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.

- in this i will visual also because you will explain clearly and not like just read it so the listener will not confuse to your explaination.

digestive system

The food must be broken down into chemicals that the body can use. This whole process is called digestion. Some of the organs involved in digestion are the mouth, esophagus, stomach, small and large intestines, gallbladder, pancreas and liver.

- in this topic it easy to understand and to explain clearly with a use of visual so they will see and manipulate it.

cardiovascular system

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,.




- will explain this if i summarize so i can understand more and explain everything to them and they understand it.

different senses

this senses have 4 type
*sight or vision is the ability of the brain and eye to detect electromagnetic waves within the visible range (light) which is why people see interpreting the image as "sight.
*hearing or vibration is the sense sound of perception.
*taste is one of the two main "chemical" senses
* smell is the other "chemical" sense.
* touch also called tactition , is a perception resulting from activation of neural receptors, generally in the skin including hair follicles, but also in the tongue , throat and mucosa.

- this i will explain this by using visual or power point to explain clearly and my classmate will understand clearly.

endocrine

Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into theblood rather than through a duct. The main endocrine glands include the pituitary gland, pancreas, ovaries, testes, thyroid gland, and adrenal gland. The hypothalamus is a neuroendocrine organ. Other organs which are not so well known for their endocrine activity include the stomach, which produces such hormones as ghrelin.
