layer is called the myocardium and is composed of cardiac muscle which contracts. The inner layer is called the endocardium and is in contact with the blood that the heart pumps. Also‚ it merges with the inner lining of blood vessels and covers heart valves. The human heart has four chambers‚ two superior atria and two inferior ventricles. The atria are the receiving

1/Nastic Movement: "Nastic movements are non-directional responses to stimuli (e.g. temperature‚ humidity‚ light irradiance). The movement can be due to changes in turgor or changes in growth. Nastic movements differ from tropic movements in that the direction of tropic responses depends on the direction of the stimulus‚ whereas the direction of nastic movements is independent of the stimulus. The rate or frequency of these responses increases as intensity of the stimulus increases. An example of

and the lower parts of the body to the heart. This large veins lead into the right atrium where the pumping heart forces the red blood cells through the tricuspid valve into the right ventricle. The valve stops blood from flowing backwards into the right atrium once it’s in the right ventricle they are then pumped through the pulmonary valve into the pulmonary artery and on to the lungs. The arteries carry blood away from the heart (always oxygenated apart from the pulmonary artery which goes from

Objective 1. To demonstrate the relationship between the pressure and temperature of saturated steam in equilibrium with water. 2. To determine the vapour pressure curve. Introduction Properties of a fluid can change when heat and work are applied to it. There’s an interchange between the fluid and its surroundings when heat and work are applied according to the study of thermodynamics. Substances such as gases and vapors are often referred as P-V-T substances. Theory: An ideal gas

The key is the difference between the two readings of this cylinder after infecting oil. If the compression increases after adding the oil‚ it has increased the seal of the piston rings and resulted in higher readings. If the readings stay the same the valve or valve seat is faulty and the cylinder head would have to be removed and the valve/seat
