lymphatic system (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 oflymphocytes, which includes the spleen, thymus, bone marrow and the lymphoid tissue associated with the digestive system..

if i were to explain lymphatic system to others it is the one that protect us from virus and bacterias.. the 1st layer of defense is the skin. next protection is the saliva it has many parts of you explore it furthermore..

respiratory system

the respiratory system's function is to allow gas 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

if i were to explain respiratory system to others i will explain that respiratory system has many parts .

the major function of the respiratory system is gas exchange between the external environment and an organism's circulatory system. In humans and mammals, this exchange facilitatesoxygenation of the blood with a concomitant removal of carbon dioxide and other gaseous metabolic wastes from the circulation. As gas exchange occurs, the acid-base balance of the body is maintained as part of homeostasis.

the heart

The heart is a muscular organ found in all vertebrates that is responsible for pumping blood throughout the blood vessels by repeated, rhythmic contractions. The term cardiac (as in cardiology) means "related to the heart" and comes from the Greek καρδιά, kardia, for "heart."

The vertebrate heart is composed of cardiac muscle, which is an involuntary striated muscle tissue found only within this organ. The average human heart, beating at 72 beats per minute, will beat approximately 2.5 billion times during an average 66 year lifespan. It weighs on average 250 g to 300 g in females and 300 g to 350 g in males

the five sense of the human body..

the five senses of the human body.if i were to explain this topic the sight, smell, sound, taste and touch. Each one of them is really important in your everyday life. You use at least one of your five senses every moment of every day and they are on duty even when you are asleep! Your senses work together to let your brain know what is going on around you. They help to keep you safe by warning you of any danger. the report for this topic would have been better if patrick show some visual aids.

endocrine system

The 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.

The brain

The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.^[1] Most of the expansion comes from the cerebral cortex, a convoluted layer of neural tissue that covers the surface of the forebrain. Especially expanded are the frontal lobes, which are involved inexecutive functions such as self-control, planning, reasoning, and abstract thought. The portion of the brain devoted to vision is also greatly enlarged in human beings.

if i were to explain brain to someone i would say to them that brain has many different parts if you will study it more further

i would like to congratulate jezzali occeno our reporter for this topic i understand the brain clearly.
