The septum form is that ist a wall that divides the left side of the heart from the right side. This keeps the deoxygenated blood from mixing with the oxygenated blood. With the septum having the function of being like a wall it allows it to keep its function of being a barrier between the left and right side of the heart. Respiratory The lungs form is pretty much a sac that is like a balloon. It is flexible in order to inflate and deflate. The lung being like a balloon and flexible allows it to

ANIMAL TISSUES 1. Classify the animal tissues. On the basis of the function they perform‚ animal tissues are classified into four different types. They are: i) Epithelial tissue ii) Connective tissue iii) Muscular tissue iv) Nervous tissue 2. What are epithelial tissues? What are the characteristic features of these tissues? The covering or protective tissues in the animal body are called epithelial tissues. They also perform the functions of secretion and absorption

Kidney The human body is a wonderful thing. It ’s not everyday that one takes a second to ponder about all of the wonderful things the human body can do. The brain helps us to be the most intelligent beings on earth. Our hearts beat to keep us alive. What about the kidneys? People typically do not think about what they do for us or consider them one of the human ’s most amazing organs. What if humans only had one kidney? Would there be any disadvantages compared to the typical human with two kidneys

whilst this is happening the random motion is still occurring it’s just not in one direction. Diffusion takes place within the body through the cell membranes. Although these are freely passable to the diffusing molecules providing the barrier are thin. In the lungs there are two simple squamous epithelial cells which separates the dissolved gases in the alveoli from the blood in the pulmonary capillaries. No source of energy is required for diffusion of molecules. See diagram of diffusion below

Effects Of Alcohol On A Human Body During this essay I will explain the physical effects and the emotional effects alcohol can have on the human body. I’m also going to be showing the long and short term effects it comes into play with. This first section is going to cover the emotional and physical effects alcohol can have on the human body. Yes the feeling might feel great but after this sentence I’m going to show how you are harming yourself by drinking over your limit. Brain damage- Binge drinking

Blood is pumped through the body by the heart by two different circuits‚ one of the circuits in the systemic circuit and the second circuit is the pulmonary circuit. The system circuit‚ starts via the left atrium and passing the mistral valve down into the left ventricle. The ventricle will then contract shortly after the atria have started relaxing and followed by the closing of the atrioventricular valves‚ so blood does not back wash into the atrium. Pressure will becoming higher in the left

The Organ Systems of the Human Body The human body is made up of 11 organ systems. The Integumentary System‚ Skeletal System‚ Muscular System‚ Nervous System‚ Endocrine System‚ Circulatory System‚ Lymphatic System‚ Respiratory System‚ Urinary System‚ Digestive System‚ and Reproductive System for the male and female. Also‚ we have the Immune System which is an accumulation of cells rather than an organ system. Protection‚ support and movement are the main functions of the Integumentary system
