This is very important as this allows osmosis occurs in our bodies. Plasma is forced out of the capillaries under high hydrostatic pressure to form tissue fluid. Some of the tissue fluid is return in capillary ends and some is returned to the blood by the lymphatic system. Plasma carries glucose, ions, waste product, respiratory gases and hormones around the body. Small molecules such as oxygen and carbon dioxide can diffuse in and out of the cells through the phospholipid bilayer; ions and glucose molecules enter and leave the cell via the channel proteins.
The air which we breathe in which is kept in the lungs, is the transferred into blood. The blood then goes around the heart, which then pumps oxygenated blood from lungs back into the body. The 2 systems also work together in order to get rid of carbon dioxide which is there as a metabolic waste product. D1
From the stomach the food travels through the small intestine, which transfers water and nutrients into the blood and then other parts of the body. The liver processes the nutrients and decides where they will be sent in the body. It filters out all the waste harmful substances, some are which are made into digestive juices. Finally whatever is waste and cannot be digested moves through the large intestine. When the body has taken
In the exogenous path the Epithelial, cell lining also known as the small intestines, readily takes in lipids from the food. These lipids including phospholipids, cholesterol and triglycerides, merge with apolipoprotein B-48. In their circulation via the lymphatic vessels, the nascent chylomicrons pass the liver circulation and draining through the thoracic duct and into the bloodstream follows. In the bloodstream, High Density Lipid particles donate apolipoprotein E and apolipoprotein C-II to the nascent chylomicron that is now mature. Through apolipoprotein C-II, the mature chylomicrons activate lipoprotein lipase (LPL).
The circulatory system, also called the cardiovascular system, is an organ system that permits blood to circulate and transportnutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis. The study of the blood flow is called hemodynamics. The study of the properties of the blood flow is called hemorheology. The circulatory system is often seen to comprise both the cardiovascular system, which distributes blood, and the lymphatic system, which circulates lymph. [1] These are two separate systems.
The human respiratory system is composed of the nasal passage, the pharynx, larynx, the trachea, bronchi and lungs. It is responsible for the process of respiration that is vital to the survival of living beings. Respiration is the process of obtaining and using oxygen, while eliminating carbon dioxide. It is the process by which human beings take in the oxygen from their environment and give out the carbon dioxide that is produced as a result of chemical reactions within the cells. The specialized system that brings about this critical process of respiration in human beings is known as the human respiratory system.
Aerobic respiration is oxygen-based cellular respiration that uses oxygen to generate energies through the breakdown of carbohydrates, fats, and proteins. Anaerobic respiration is a form of respiration using electron acceptors to generate energy by the oxidation of nutrients and using an external electron acceptor other than oxygen. Anaerobic respiration is a common occurrence. Microbes that carry out this process are common in the environment and their activities plays a major role in the global cycling of elements such as Nitrogen, Sulfur, and Carbon. There are 5 different types of Anaerobic Respiration: 1.
(Insert diagram 1 below) This is the exchange of gases occurring within our bodies by diffusion. It is necessary or vital to occur since we need oxygen from the air in the blood to remove the waste from our carbon dioxide. This explains why therefore a large surface area is required for the alveoli as it increases the rate at which oxygen is diffused. The large surface area of alveoli is also used and useful for energy
The circulatory system plays an important role in controlling body temperature. The blood supplying the muscles with oxygen and nutrients absorbs much of this heat and carries it away to other parts of the body. If the body gets too warm, blood vessels near the skin enlarge to diffuse excess heat outward through the skin. In cold atmospheres, blood vessels constrict to retain heat. The heart, blood, and blood vessels are the three main elements that make up the circulatory system.
The Respiratory System In our bodies many organs take part in the process of respiration. We call them organs of the respiratory system. The main organs of the human respiratory system are as follows: Nose, Pharynx, Larynx, Trachea, Bronchi, Lungs, Alveoli and Diaphragm. The respiratory systems main purpose is to supply oxygenated blood in order for the blood to deliver oxygen to all parts of the body. Breathing gives us the ability to inhale oxygen and exhale carbon dioxide.
