P4: Explain the physiology of two named body systems in relation to energy metabolism in the body. Cardiovascular System This system transports materials to the liver and body cells through the bloodstream that is pumped by the heart. Blood Blood is a liquid tissue made up of; plasma, platelets, white and red blood cells and is necessary for every part of the body. The blood contains many different materials and cells and there is fluid called plasma which contains many substances dissolved in it. 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. Red blood cells contain hemoglobin, an iron-containing protein that sticks to oxygen so it can be carried round the circulatory system. In high…show more content…
The main of the four is; nitrogen even though it does nothing for the respiratory system. Waste products of the internal in cells are; carbon dioxide and water. Breathing replenishes oxygen in the lungs. The opposite happens with carbon dioxide; high concentration in the blood and low concentration; in the refreshed air. Diffusion helps to remove dissolved carbon dioxide from the blood and into the expelled air from lungs. Diffusion is the molecules (gas or liquid) moving from high concentration to low concentration. M1: Discuss the role of energy in the body. Our bodies need energy to work properly. The energy we need and use comes from the type of foods we eat. However this isn’t an instant process and our body’s need to change it so our cells can use it. Where in our diet energy comes
