Biology about com organ systems
The human body is made up of several organ systems that work together to keep the body functioning properly. Each organ system has a specific role and is essential for the overall health and well-being of an individual.
The digestive system is responsible for breaking down and absorbing nutrients from the food we eat. It consists of the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. The mouth is where digestion begins as food is mechanically broken down by the teeth and mixed with saliva, which contains enzymes that start the chemical digestion of carbohydrates. The esophagus is a muscular tube that transports the food to the stomach via muscular contractions called peristalsis. The stomach is a muscular sac that mixes the food with gastric juices, which contain hydrochloric acid and enzymes that continue the process of breaking down the food. The small intestine is where most of the nutrients from the food are absorbed into the bloodstream. The large intestine absorbs water and electrolytes from the remaining indigestible material and stores it until it is eliminated through the rectum and anus.
The respiratory system is responsible for bringing oxygen into the body and removing carbon dioxide. It consists of the nose, pharynx, larynx, trachea, bronchi, and lungs. The nose and pharynx are the passageways for air to enter the body. The larynx, or voice box, contains the vocal cords and helps to regulate the flow of air. The trachea, or windpipe, branches into the left and right bronchi, which lead to the lungs. The lungs are the main organs of the respiratory system and are responsible for exchanging gases with the blood. Oxygen from the air we breathe is absorbed into the bloodstream and carbon dioxide is exhaled out of the body.
The circulatory system is responsible for pumping and transporting blood throughout the body. It consists of the heart, blood vessels, and blood. The heart is a muscular organ that pumps blood to the body's cells. The blood vessels are tubes that carry the blood to and from the heart. Arteries carry oxygenated blood away from the heart to the body's cells and veins carry deoxygenated blood back to the heart. The blood is made up of red and white blood cells and platelets, which are suspended in plasma. Red blood cells carry oxygen to the body's cells and white blood cells help to fight infection. Platelets help with blood clotting.
The nervous system is responsible for coordinating and controlling the body's responses to internal and external stimuli. It consists of the brain, spinal cord, and nerves. The brain is the control center of the body and is responsible for receiving and interpreting stimuli and sending out appropriate responses. The spinal cord is a long, delicate tube of nerve tissue that runs from the brain down through the center of the back. It carries messages to and from the brain and the rest of the body. The nerves are a network of fibers that carry messages to and from the spinal cord and the rest of the body.
The endocrine system is a system of glands that produce and secrete hormones into the bloodstream. These hormones are chemical messengers that help to regulate the body's functions. The endocrine system consists of the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, and gonads (testes in males and ovaries in females). Each gland has a specific role in regulating the body's functions.
The musculoskeletal system is responsible for movement and support. It consists of the bones, muscles, and joints. The bones provide a framework for the body and protect the internal organs. The muscles allow for movement by contracting and relaxing

The hypothalamus secretes hormones that travel directly to cells of the pituitary gland, which is located beneath it. As with most transplant patients, this patient will have to take immunosuppressing drugs for the rest of his life so his immune system will not reject the organ. Most cells in large multicellular organisms do not directly exchange goods such as nutrients and wastes with the external environment; instead, they are surrounded by an internal environment of extracellular fluid—literally, fluid outside of cells. Most of its hormones either turn on or turn off other endocrine glands. Hormones travel throughout the body.
THE ORGAN SYSTEM
Organs exist in most multicellular organisms, including humans, other animals, and plants. An example of connective tissue that might not be very obvious is tendons. It also carries wastes away from cells. These are the brain, heart, kidneys, liver and lungs. But did you ever wonder why we associate love with the heart? You are well on your way toward mastering the basics of organ systems in the body. Vital Organs The human body contains five organs that are considered vital for survival.
Multicellular organisms, such as humans, are made up of a large number of cells. Other animals breathe through gills or even through their skin. Both the systems combined together is known as the neuroendocrine system. Each system is also described in more detail in the text that follows. Circulatory System Image Source: Wikimedia Commons The circulatory system consists of the heart and the blood vessels.
Organ Systems Puzzle
The carbon dioxide produced in cellular respiration leaves the body by the opposite route. Do you know the functions of any of the other organs in the diagram? What is the function of the respiratory system? The human body is made up of a number of inter-related systems that work together to maintain a stable internal environment. An organ is a group of What are Different Organ Systems Made up of? In the lungs, oxygen and carbon dioxide are exchanged between the outside air and the blood. Less advanced organisms of the taxa such as Placozoa, Sponges and Radiata, do not show any such consolidation of tissues into organs. The organ that controls those functions, in actuality, is the brain. Use this shadow diagram of human anatomy to locate the five organs described above: heart, brain, kidneys, liver, and lungs. Human Organ Systems Functionally related organs often cooperate to form whole organ systems.
How many organ systems are there? Explained by FAQ Blog
Male and Female Reproductive Systems The reproductive system is the only body system that differs substantially between males and females. Organ system The many systems of the body serve various functions. Once in the blood, endocrine hormones circulate to cells everywhere in the body. However, you may have never heard of a penis transplant. The cardiovascular system also equalizes body temperature and transports endocrine hormones to cells in the body where they are needed. They are both briefly described below: Tissue Systems The biological definition of tissue places it in-between the cells and organs in the organizational level of the cell.

Organs and Organ Systems
The lymphatic system also includes many small collections of tissue, called lymph nodes, and an organ called the spleen, both of which remove pathogens and cellular debris from the lymph or blood. The immune system B. The classical tools involve the paraffin block or the agarose gel depending on whether the tissue sample is from an animal or plant, in which the tissue is embedded and sectioned as per the requirement, and then after the application of histological stain, it is observed under the microscope. Organs with comparable tasks commonly collaborate to build whole organ systems. For each organ system, identify some of its organs and functions.
It controls all activities of the other systems. It is made up of the penis, testis, prostate gland and scrotum in males and the ovary, uterus, vagina, and fallopian tube in females. Blood is transported in a very specific route because oxygenated blood cannot mix with deoxygenated blood. This organ system is divided into two major groups: the peripheral nervous system and the central nervous system. Vital Organs The human body contains five organs that are considered vital for survival: the heart, brain, kidneys, liver, and lungs.
The human body has 11 different organ systems. The kidneys also produce an enzyme called renin and a variety of hormones. This causes cortisol and adrenaline to be released. An example of an organ system is the circulatory system, which includes the heart, arteries, veins, and capillaries. Female organisms produce eggs through the process of oogenesis. Organs with comparable tasks commonly collaborate to build whole organ systems. All parts of the plant above the ground also include the functionally distinct leaf and flower organs as well which are classified as the shoot organ system.
