H.5.6 Outline how tissue fluid and lymph are formed in body tissues.
H.5.7 Outline the transport functions of the lymphatic system.
 * pressure of blood in capillaries is greater than the pressure of fluid around cells causing fluid to seep

=Gas Exchange=

//Limit this to effects of changes in carbon dioxide concentration leading to a lowering of blood pH. This is detected by chemosensors in the aorta and carotid arteries that send impulses to the breathing centre of the brain. Nerve impulses are then sent to the diaphgram and the intercostal muscles to// //increase contraction of relaxation rates.//
 * H.6.1 Define partial pressure**
 * H.6.2 Explain the oxygen dissociation curves of adult and fetal hemoglobin and myglobin.**
 * H.6.3 Describe how carbon dioxide is carried by the blood, including the action of carbonic anhydrase, the chloride shift and buffering by plasma proteins.**
 * H.6.4 Explain the role of the Bohr shift in the supply of oxygen to respiring tissues.**
 * H.6.5 Explain how and why ventilation rate varies with exercise.**

//Mountain sickness may occur when a person travels quickly from a low to a high altitude. Over a period of time the person becomes acclimatized: red blood cell production and ventilation rate increase. People living permanently at high altitude have greater lung surface area and larger vital capacity than those living at sea level.//
 * H.6.6 Outline the possible causes of lung cancer and asthma and their effects on the gas exchange system**
 * H.6.7 Explain the problem of gas exchange at high altitudes and the way the body acclimatizes**
