Respiratory system From Wikipedia‚ the free encyclopedia See also: Respiratory tract Respiratory system A complete‚ schematic view of the human respiratory system with their parts and functions. Latin systema respiratorium The respiratory system (or ventilatory system) is the biological system that introduces respiratory gases to the interior and performs gas exchange. In humans and other mammals‚ the anatomical features of the respiratory system include airways‚ lungs‚ and the respiratory

they travel through the organs throughout the digestive system. • Carbohydrates are the body’s preferred energy source‚ and are found in the forms of starch‚ sugar and fibre. Additionally‚ carbohydrates move into the small intestine‚ where enzymes released by the pancreas break those carbohydrates into simple forms‚ so they can be absorbed into the bloodstream. • Lipids that are consumed‚ are mainly fats.

The Nervous System The nervous system is the most complex part of the body‚ as they govern our thoughts‚ feelings‚ and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease‚ stroke‚ accidents‚ etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous

The Endocrine System FOCUS: The endocrine system is one of the major regulatory systems in the body‚ along with the nervous system. However‚ the endocrine system responds more slowly‚ and has a longer-lasting‚ more general effect on the body than the nervous system. Endocrine tissues internally produce hormones which are released into the blood‚ where they are carried to target tissue and produce a response. Some hormones bind to receptors on the surface of the cell membrane‚ producing permeability

The lymphatic system The lymphatic system belongs to the circulatory system; it consists of a network of lymphatic vessels which carry around fluid which is known as lymph. These carry the fluid towards the heart in different directions. These vessels are spread out the human body. The vessels are similar to that of the circulatory systems vessels as it consists of smaller lymphatic capillaries that form vessels. Lymph fluid is when the tissue fluid is collected though the lymph capillaries. When

Muscle System Human Biology The human body is covered by muscles‚ made up of more than 650 of them. The purpose of the muscular system is for the body to move‚ maintain posture‚ and produce heat. There are three different types of muscles tissues; cardiac‚ smooth‚ and skeletal. There are also two types of muscles are in the body; voluntary and involuntary. The ones which we can move are the voluntary muscles; the ones which move on their own‚ like the heart‚ are involuntary muscles. When muscles

The Circulatory System The Circulatory System consists of the heart‚ blood and blood vessels. It performs many vital functions. It plays an important role in respiration. The circulatory system is also important in nutrition‚ in the removal of wastes and poisons‚ and in several other body processes. The functions are; Transport gases‚ like oxygen from the lungs to cells around the body and carbon dioxide from the cells to the lungs. Transport nutrients like glucose. Transport wastes from cells

How does the immune system react to pathogens? It fights off the pathogen by Leukocytes also known as white blood cells. When a pathogen enters the body the immune system becomes alert to it and sends out sends out the Phagocytes (a type of Leukocytes) which engulf the pathogens. If the body has a weak immune system‚ the pathogens eventually overtake the body which can result in a disease. How do the different pieces of the immune system work together? The bone marrow‚ the lymph nodes‚ the spleen

What is the Urinary System? The urinary is system is a system of production‚ storage‚ and the elimination of urine. Formation and elimination of the urine is important for the human body because it contains nitrogenous wastes of the body that must be eliminated to maintain homeostasis. The urinary system is important for keeping the internal environment of the body clean. This particular system maintains proper homeostasis of water‚ salts and nitrogenous wastes (Iqba‚ 2010). There are four major
