Organ What You Need to Know

The brain is the control center of the nervous system, and it is responsible for coordinating all of the body's activities. The brain is made up of billions of neurons, which are specialized cells that communicate with each other through electrical and chemical signals. The brain is divided into two hemispheres, the left and right hemispheres, which are connected by the corpus callosum. The left hemisphere is responsible for language, logic, and reasoning, while the right hemisphere is responsible for spatial awareness, creativity, and emotion.

The heart is a muscular organ that pumps blood throughout the body. The heart is divided into four chambers: the right atrium, the right ventricle, the left atrium, and the left ventricle. The right atrium receives blood from the body, and the right ventricle pumps the blood to the lungs. The left atrium receives blood from the lungs, and the left ventricle pumps the blood to the body.

The lungs are two large, spongy organs that are responsible for gas exchange. The lungs are made up of millions of tiny air sacs called alveoli, which are lined with capillaries. The capillaries are tiny blood vessels that allow oxygen from the air to pass into the blood, and carbon dioxide from the blood to pass into the air.

The liver is a large, glandular organ that is responsible for many important functions, including detoxifying the blood, storing glycogen, and producing bile. The liver is also involved in the metabolism of proteins, fats, and carbohydrates.

The kidneys are two bean-shaped organs that are responsible for filtering waste products from the blood and producing urine. The kidneys also help to regulate blood pressure and electrolyte balance.

The stomach is a J-shaped organ that is responsible for breaking down food. The stomach is lined with a layer of mucus that protects it from the acidic stomach juices. The stomach also produces enzymes that help to break down proteins and fats.

The intestines are a long, coiled tube that is responsible for absorbing nutrients from food. The intestines are lined with tiny villi, which are small, finger-like projections that increase the surface area of the intestines and help to absorb nutrients.

The pancreas is a small, glandular organ that is responsible for producing enzymes that help to break down proteins, fats, and carbohydrates. The pancreas also produces hormones, such as insulin and glucagon, that help to regulate blood sugar levels.

The thyroid gland is a small, butterfly-shaped gland that is responsible for producing hormones that regulate metabolism. The thyroid gland also helps to regulate growth and development.

The adrenal glands are two small, triangular glands that are located on top of the kidneys. The adrenal glands produce hormones, such as adrenaline and cortisol, that help the body to respond to stress.
