Human biology including physiology, anatomy, organ systems and more. Anatomy is the analysis of the structure of living organisms. This subdiscipline of biology could be further classified into the analysis of large scale anatomical structures (gross anatomy) and the research of microscopic anatomical structures (microscopic anatomy).
The human body is composed of several organ systems that all interact as a unit to ensure the body maintains functioning. You can find some major organ systems in the human body, each of which performs a different part in helping the body function.
This system is comprised of the blood, heart, lymphatics and blood vessels. It is the bodyís delivery system, focused on circulating blood to supply oxygen and nutrients to each part of our bodies.
The goal of the digestive system is always to change the food you eat into something useful for our bodies. When you eat, your body utilizes this system to digest food so your cells can utilize it to make energy. The organs involved in this system contain the stomach, mouth and intestines.
This system is comprised of a collection of glands, such as the thyroid glands and pituitary, as well as the testes and ovaries. It coordinates, regulates and controls several body functions by secreting chemicals to the bloodstream. These secretions assist control growth, moods and development and metabolism.
The skeleton gives support and structure for the body. Joints are the areas in which bones come together. They permit the skeleton to be flexible for motion. In a joint, bones do not straight contact one another. Instead, they are cushioned by cartilage within the joint, synovial membranes round the fluid and joint.
Muscles & Nerves
Muscles allow you to move your eyes. Ocular nerves enable you to interpret exactly what you see and blood vessels maintain your eyes oxygenated. Six muscles, collectively referred to as the extraocular muscles, move the eyeball. A 7th muscle moves the eyelid and is also present in the orbit.
Circulatory System and Blood
The circulatory system is actually a vast network of vessels and organs that is in charge of the blood circulation, oxygen, nutrients and other gases and hormones to and through cells. With no circulatory system, our bodies would not be capable of fight disease or maintain a stable inner environment for example proper temperature and pH called homeostasis.
The respiratory system is comprised of tissues and organs that assist you breathe. The primary parts of this system are the lungs, the airways and linked blood vessels, as well as the muscles that allow breathing.
Digestive SystemThe human digestive system is a complicated series of glands and organs that processes meals. In order to make use of the food we consume, the body has to break the food down into smaller molecules that it can easily process; it also needs to excrete waste.
Excretory and reproductive systems each have essential but various functions in animals. The excretory system keeps ion, water and nitrogen balance inside the body and removes wastes. The reproductive system generates new individuals of a species. Both excretory and reproductive systems are under endocrine control however are also influenced by the exterior environment.
