The lungs are two sponge-like, cone-shaped structures that fill most of the chest cavity. Their essential function is to provide oxygen from inhaled air to the bloodstream and to exhale carbon dioxide. The liver lies on the right side of the abdominal cavity beneath the diaphragm. Its main function is to process the contents of the blood to ensure composition remains the same. This process involves breaking down fats, producing urea, filtering harmful substances and maintaining a proper level of glucose in the blood.
The bladder is a muscular organ located in the pelvic cavity. It stretches to store urine and contracts to release urine. The kidneys are two bean-shaped organs located at the back of the abdominal cavity, one on each side of the spinal column. The heart is a hollow, muscular organ that pumps blood through the blood vessels by repeated, rhythmic contractions. The stomach is a muscular, elastic, pear-shaped bag, lying crosswise in the abdominal cavity beneath the diaphragm.
Its main purpose is digestion of food through production of gastric juices which break down, mix and churn the food into a thin liquid.
The intestines are located between the stomach and the anus and are divided into two major sections: the small intestine and the large intestine. The function of the small intestine is to absorb most ingested food. An organ is made of several types of tissue and therefore several types of cells Cells Often thought of as the smallest unit of a living organism, a cell is made up of many even smaller parts, each with its own function. Human cells vary in size, but all are quite small. For example, the heart Biology of the Heart The heart and blood vessels constitute the cardiovascular circulatory system.
The heart pumps the blood to the lungs so it can pick up oxygen and then pumps oxygen-rich blood to the body The eye Structure and Function of the Eyes The structures and functions of the eyes are complex.
Each eye constantly adjusts the amount of light it lets in, focuses on objects near and far, and produces continuous images that are instantly Even an organ as apparently simple as the gallbladder Gallbladder and Biliary Tract The gallbladder is a small, pear-shaped, muscular storage sac that holds bile and is interconnected to the liver by ducts known as the biliary tract. Exclusive : Comprehensive analysis finds harm from head to toe, including dementia, heart and lung disease, fertility problems and reduced intelligence.
Damian Carrington Environment editor. Air pollution may be damaging every organ and virtually every cell in the human body, according to a comprehensive new global review. The research shows head-to-toe harm, from heart and lung disease to diabetes and dementia, and from liver problems and bladder cancer to brittle bones and damaged skin. Fertility, foetuses and children are also affected by toxic air, the review found.
The systemic damage is the result of pollutants causing inflammation that then floods through the body and ultrafine particles being carried around the body by the bloodstream. New analysis indicates 8. If something is missing [from the review] it is probably because there was no research yet. There are more than 70, scientific papers to demonstrate that air pollution is affecting our health.
This results in breathing problems, from asthma to emphysema to lung cancer. There is now overwhelming evidence that air pollution results in serious harm not only to the lungs, but also to the heart. The nervous system allows us to perceive, comprehend, and respond to the world around us.
The female reproductive system encompasses all necessary female organs needed to conceive and bear a child. The male reproductive system consists of a series of organs used during sexual intercourse and procreation. The primary organs are the gonads, or sex glands, which produce sperm.
In men, these are the testes. We break down some of the basics surrounding what masculinity is, how it harms men, and what we can do about it. Ruined orgasms are about control, domination, and power. And with the right partner s , these aspects of kink can all be super sexy. Autosexual people are mainly sexually attracted to themselves. They typically experience little to no sexual attraction to other people.
To embody a healthy sexual self, you must actively engage in yourself.
