tissue - organ - organ system - organism Respiratory system We need air to stay alive air is defined as a homogenous mixture made out of nitrogen, oxygen, carbon dioxide, and other gases oxygen is the important gas that suport energy production in living beings air is abiotic biotic is life Functions of respiratory system 1, gets oxygen in the body and carbon dioxide out 2, protects our body from harmful particles that enter our nose 3, site of gas exchange 3 regions nasopharyngeal trachea bronchial bronchioalveolar Parts nose - air enters our body through two holes in our nose, the two nostrils, it is a warm passage lined with blood capillaries, it is moist as it secretes mucus, nose serves as filters through the nose hairs nasal cavity - filters air, and moistens air pharynx - common passageway for air and food, it is a hollow tube from nose to top of trachea larynx - voice box, connect throat to trachea trachea - passageway for food and air, surface is lined with cilia to prevent foreign bodies Lungs - main organ of respiratory system consist of 2 lobes bronchi is a tree like structure where air is lead to the branches called bronchioles 60 thousand bronchioles in a adult, then bronchioles lead into the alveoli where air is stored there is 500 million alveoli in lung, air exit through capillary diseases common cold - virus infecting upper respiratory tract duration: week treatment: rest and drink fluid Influenza- influenza virus duration two to five days, can lead to pneumonia pneumonia - infection of lung, alveoli inflamed and filled with fluid treatment - take all prescribed medication Tuberculosis - mycobacterium tuberculosis treatment - six months asthma - chronic allergic condition bronchitis - inflammation of bronchi treatment: fluids to medication emphysema- alveoli is damaged no treatment COPD - chronic obstructive pulmonary disease combination of diseases Circulatory system circulatory system is divided into two, the cardiovascular system, and the lymphatic system main function carry oxygen and nutrients to cell of body heart beats 100 thousand times a day 35 million beats per year 4 chambers of heart left ventricle and atrium right ventricle and atrium three pathways of heart arteries - carry blood away from heart vein - carry blood to the heart capillaries - gas exchange artery arteriole capillary venule vein blood river of life blood is body temperature protects against toxin pathogen injuries ph. of 7.4 transport nutrients red blood cells or erythrocytes, erythro meaning red, cytes meaning cell hemoglobin thing that carries air, it is iron, 5 million of 4bc per millimeter of blood, it is shaped biconcave whiteblood cells leuko cytes, leuko meaning white born in bone marrow protect body from disease irregular shape contain nucleus 100 million wbc per day 4k to 11k every milimeter of blood ra receives unoxygenated blood from body rv pumps the unoxygenated blood into the lungs la receives oxygen rich blood from lungs lv pumps oxygenated blood into body disease of circulatory system stroke - sudden lose of brain function when blood cut off coronary artery disease buildup of plaque in arteries coronary heart disease - buildup of fats on artery walls hypertensive heart disease - thickening of hear, tightened arterioles rheumatic heart disease - valves are damaged by rheumatic fever hemophilia- continuous bleeding and difficult in clotting anemia - rbc decrease leukemia - abnormal increase in wbc Genes and chromosomes genetic is scientific study of genes and heredity father of genetics is gregor mendel gene is segment of dna, dna is shaped like corkscrew ladder called double helix dna meaning deoxyribonucleic acid dna provide instruction human consist of 20 thousand genes chromatid into chromosomes 23 pairs of chromosomes 46 total 1 - 22 chromosome is our characteristic called autosome 23 is sex - sex chromosome women have x chromosome man have xy chromosome dominant recessive alleles causes of extinction asteroid climate change disease loss of habitat lack of genetic diversity Photosynthesis photo meaning light synthesis meaning putting together 3 major events 1 light into chemical energy 2 water into oxygen 3 carbon dioxide into sugar leaves specialized organs for photosynthesis stomata, like capillary allow oxygen to exit and carbon dioxide to enter chloroplast is where photosynthesis takes place chlorophyll take in sunlight - reflect green light, absorb red and blue thylakoid membrane stacked is granum xylem take water from ground - like blood vessel
