Plasma carries food from the stomach to cells but carries waste from the cells to the kidneys and intestine. The body needs lots of haemoglobin because it will combine with the gases; oxygen and carbon dioxide. The red cells carry the oxygen in the arteries and capillaries to cells of the body. One function of the blood is to transport materials within plasma and hemoglobin around the body. Plasma contains hormones, nutrients and waste substances.
P4- Explain the Physiology of two named body systems in relation to energy metabolism in the body. In this essay I am going to be explaining how energy is made in the body and two body systems that help to produce this energy. “The metabolic systems are responsible for the chemical reactions within the body. These reactions are involved in the maintenance of the living organism and may be involved in reactions that break compounds down catabolic reactions or reactions which build compounds up anabolic reactions”. (King R 2012) They all require energy to work.
1. Cardiovascular System is a complex network of the heart, blood vessels and blood. Its job is to deliver nutrients to the human body and remove excretory products from the body parts, it’s also protects the human body against infections, distribution of heat. At the centre of the cardiovascular system is the heart, a four chambered pump that dispenses blood to the arteries. The arteries carry nutrients and oxygenated blood to the body’s tissues.
The difference is internal respiration happens at the cellular level while external respiration is the actual breaths. 2. What are the key functions overall of the respiratory system? The key functions of the respiratory system is to bring air and blood into the alveolar air sacs so that the air can enter into the bloodstream while the carbon dioxide exits. It also maintains the body’s pH levels and body temperature.
Here it attaches to the hemoglobin molecules inside red blood cells. The red blood cells are carried by the blood vessels to all parts of the body. The hemoglobin releases oxygen in the periphery, and picks up carbon dioxide (CO2). The CO2 attached to the hemoglobin molecules in the red blood cells is then transported to the lungs, where it diffuses across the walls into the alveoli, and is breathed out. When your blood gets to your lungs, the oxygen from your lungs gets put into your bloodstream.
The sum of all chemical reactions in the body is? Metabolism 27. Polysaccharide that serves as a storage form of energy in muscle and liver cells? Glycogen 28. Two organ systems that regulate and maintain homeostasis are the Nervous and endocrine systems 29.
Fat is also store in the system as triglycerides that forms three of our good saturated fatty acids. This process is formed on the cellular level of respiration. Adenosine triphosphate is our main source of receiving energy to the body. 1. Describe how the storage of molecules is broken down and used to produce ATP.
Undigested food travels into the large intestine. Excretes non-absorbed material passed from the small intestine. Water absorption. Stores waste and house bacteria that make vitamin K. Rectum – Feces are stored in the rectum before being expelled along the anal canal. Liver – Major role in dealing with the nutrient products of food digestion.

The chemical produced by the digestive system that breakdown foods are called enzymes. One of the main substances required for energy and resulting from the digestion is glucose. This is stored as glycogen by the liver and is released back into the circulation as glucose when required. The pancreas produces insulin which plays a role regulating blood glucose levels. Glucose is important because it is an energy molecule that is broken down to give the cell ATP energy to use for the cell’s
