Heart - Pumps blood and provides oxygen to rest of body

Veins - Highway for blood to be transported from body to heart

The CV System provides nutrients & oxygen, carries away wastes, & helps fight disease…

Provides oxygen to the blood and removes carbon dioxide from the body… 1. External Respiration: oxygen moves from lungs into the blood & carbon dioxide moves from blood into lungs. 2. Internal Respiration: oxygen moves from the blood into the cells & carbon dioxide moves from the cells into the blood.

Your nose lets you smell and it's a big part of why you are able to taste things. The nose is also the main gate to the respiratory system, your body's system for breathing.

Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system's main job is to move fresh air into your body while removing waste gases.

Bronchitis- inflammation of the bronchi caused by infection or exposure to irritants such as tobacco and air pollution.

Pneumonia- inflammation of the lungs caused by a viral or bacterial infection.

Asthma- an inflammatory condition in which the trachea, bronchi, and bronchioles become narrowed, causing difficulty in breathing.

Tips for a healthy respiratory system don't smoke. avoid harmful environmental factors such as smoke, dusts and chemicals. exercise (check with your doctor first if you have a health condition), preferably away from busy roads with high air pollution. wash your hands regularly to prevent infections.

Also known as the oral cavity, the mouth is the hollow cavity that allows food and air to enter the body. The mouth contains many other organs - such as the teeth, tongue, and the ducts of the salivary glands - that work together to aid in the ingestion and digestion of food

The esophagus is the muscular tube that carries food and liquids from your mouth to the stomach. You may not be aware of your esophagus until you swallow something too large, too hot, or too cold. You may also notice it when something is wrong. You may feel pain or have trouble swallowing.

The small intestine, or small bowel, is a hollow tube about 20 feet long that runs from the stomach to the beginning of the large intestine. The small intestine breaks down food from the stomach and absorbs much of the nutrients from the food.

The large intestine is much broader than the small intestine and takes a much straighter path through your belly, or abdomen. The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over.

Constipation- a condition in which feces (poop) becomes dry and hard and bowel movements are difficult. Cause- lack of water and/or fiber in the diet.

The hypothalamus is a part of the brain that has a vital role in controlling many bodily functions including the release of hormones from the pituitary gland.

Pituitary gland Despite its small size, the gland influences nearly every part of your body. The hormones it produces help regulate important functions, such as growth, blood pressure and reproduction.

The thyroid gland is a vital hormone gland: It plays a major role in the metabolism, growth and development of the human body. It helps to regulate many body functions by constantly releasing a steady amount of thyroid hormones into the bloodstream.

The parathyroid glands, which lie behind the thyroid, manufacture the parathyroid hormone, which plays a role in regulating your body's levels of the minerals calcium and phosphorus.

Diabetes Mellitus- a disorder in which the pancreas produces too little or no insulin, resulting in high blood glucose levels.

Graves’ Disease- also called hyperthyroidism/hypothyroidism. It is a disorder in which an overactive and enlarged thyroid gland produces excessive amounts of thyroxine.

Cushing's Disease- overproduction of the adrenal hormones which causes a round face, humped upper back, thin & easily bruised skin, as well as fragile bones.
