67 BONES

68 Bones are complete organs, composed of connective tissue called osseous tissue Dense connective tissue includes the cartilage and bone It consists of osteocytes surrounded by intercellular substance filled with calcium salts

69 It is composed of an outer hard layer and an inner,spongy core. Compact tissue- forms the outer layer of bones, it is arranged in concentric layers with a hollow centre which carries blood vessels and nerves.

70 The inner spongy core- forms the inside of bones, it has the yellow and red bone marrow. - the yellow bone marrow stores fat cells (leucocytes). - the yellow bone marrow stores fat cells (leucocytes). - the red bone marrow contains red cells (erythrocytes). - the red bone marrow contains red cells (erythrocytes).

71 External surface of bone is covered by periosteum- it has the function of feeding the bone

72 Several hormones regulate the activity of the bone cell 1) Osteoblasts- they are immature osteocytes which produce the bony tissue osteocytes which produce the bony tissue that replaces cartilage during ossification that replaces cartilage during ossification

73 2) Osteoclasts- they reabsorb bony tissue thus enlarging the inner bone cavity so that the bone does not become overly thick and heavy 2) Osteoclasts- they reabsorb bony tissue thus enlarging the inner bone cavity so that the bone does not become overly thick and heavy - parathyroid gland stimulates osteoclasts to remove bone and to stimulate osteoblasts to build up the bone - parathyroid gland stimulates osteoclasts to remove bone and to stimulate osteoblasts to build up the bone

74 It secretes a hormone to release calcium from bone, bones become weakened due to loss of calcium.

95 THE CIRCULATORY AND LYMPHATIC SYSTEM

96 Fluids constitute over half of an adult’s weight under normal conditions These fluids are vital in the transport of nutrients to all cells BLOOD AND OTHER BODY FLUIDS

97 Blood is composed of: liquid (plasma) – 55% liquid (plasma) – 55% formed elements ( erythrocytes, formed elements ( erythrocytes, leukocytes and platelets) – 45 % leukocytes and platelets) – 45 %

98 Plasma consists of about: - 90% of water 7% proteins less than 1% inorganic salts, organic substances, dissolved gases, hormones, antibodies hormones, antibodies and enzymes

99 Many important proteins such as serum, albumin, gamma globulin and fibrinogen are dissolved in the plasma

100 Fibrinogen is essential in the clotting process

101 All blood cells originate from hemocytoblasts They change from undifferentiated form into specialized or differentiated Hematopoiesis: :

102 Blood transports oxygen from the lungs to the body tissues, and carbon dioxide from the tissues to the lungs:

103

104 Erythrocytes The great majority of all blood cells 35 trillion in the average adult Total surface area almost the size of a football field

105 Hemoglobin enables carrying oxygen from the lungs to the tissues

106 Red blood cells are stored in the spleen They live for about 110 to 120 days About 180 million erythrocytes are destroyed every minute

107 Leukocytes Body’s primary defense against Infections These cells are larger than erythrocytes and fewer in number Blood has about 8000 leukocytes per cubic millimeter

108 Classification of leukocytes 1.Granulocytes ( neutrophils, eosinophils, basophils) 2. Agranulocytes (monocytes, lynphocytes)

109 Neutrophils form about 70%, and limphocytes about 20% of the total number

110 Platelets (thrombocytes) Small clear disk-shaped bodies About 1/3 the size of erythrocytes platelets per one cubic millimeter of blood They initiate blood clotting

111 Platelets disintegrate and adhere to the edges of the injured tissue

112 Blood coagulation (clotting) The process by which the body prevents blood loss prevents blood loss Bleeding generally stops within 5 minutes A thrombus can form within a vessel

113 Defects in blood vessels (owing to injury or disease) AnemiaAnemia NeutropeniaNeutropenia Human immunodeficiencyHuman immunodeficiency virus (HIV) virus (HIV) LeukimiaLeukimia ThrombocytopeniaThrombocytopenia HemophiliaHemophilia

114 BLOOD TRANSFUSION BLOOD GROUPS

115 Four main blood groups Type O = universal donors Type AB = universal recipients

116

117 Another important factor, called Rh factor must also be considered in blood typing. This is a very complex system : 8 principal variants of the Rh factor are known, and there are others not yet identified and grouped. For practical reasons there are 2 main groups of Rh types:  Rh positive  Rh negative Rhesus factor - Rh

126 THE CIRCULATORY AND LYMPHATIC SYSTEM

127 CARDIOVASCULAR SYSTEM The cardiovascular system is composed of the heart, blood vessels and blood. The circulatory system consists of the heart, blood vessels and lymphatics. This system transports food, oxygen, and other vital substances to all body cells and picks up waste products for disposal.

128 THE HEART The heart is a hollow, muscular organ that pumps blood through the blood vessels. It is enclosed in a fibrouserous sac called pericardium. The heart beats over times per day. It weights about one half pound and is the size of clenched fist

129 The heart has three distinctive layers of tissue: The endocardium The myocardium The epicardium The heart is divided into four chambers: Right atrium Right ventricle Left atrium Left ventricle

130 BLOOD VESSELS ARTERIES carry blood from the heart to the body tissues and organs VEINS carry blood back to the heart from body organs and tissues connect arterioles to venules connect arterioles to venules. CAPILLARIES

131 LYMPHATIC SYSTEM Lymph fluid Capillaries Lymphatic vessels Lymphatic ducts Lymph nodes

132 FUNCTION Transporting fluids from tissues back to the bloodstream Aiding in the control of infection caused by microorganisms Conveyance of lipids or fats away from the digestive organs

133 Lymph nodes of the human head and neck Regional lymph tissue

134 THE DIGESTIVE SYSTEM The digestive system is basically a long, muscular basically a long, muscular tube that begins at the tube that begins at the mouth and ends at the anus

135 The functions of the digestive system are threefold

136 Digestive enzymes are substances that speed up chemical reactions and help in the breakdown of complex nutrients Digestion can be defined as a complete process of changing the chemical and physical composition of food in order to facilitate assimilations of the nourishing ingredients of flood by the cells of the body

137 The gastrointestinial (GI) tract begins at the oral cavity or mouth

138 THE MOUTH The mouth is the first division of the digestive tube and is separable into two parts, smaller external part, the vestibule formed by the lips cheek, gums and teeth and a larger part, the mouth proper (oral) cavity behind the gums and teeth

139 Lips and cheeks Lips are a visible body part at the mouth of humans and many animals. Lips are soft, movable, and serve as the opening for food intake, and in the articulation of speech, as a tactile sensory organ as an erogenous organ used in kissing and other acts of intimacy.

140 Cheeks (Latin: buccae) constitute the area of the Latin faceface below the eyes and between the nose eyesnose faceeyesnose and the left or right ear. ear

141 Gums and teeth

142 Gingiva are part of the soft tissue lining of the mouth. They surround the teeth and provide a seal around them. Compared with the soft tissue linings of the lips and cheeks, most of the gingiva are tightly bound to the underlying bone and are designed to resist the friction of food passing over them. Healthy gingiva is usually coral pink, but may contain physiologic pigmentation. Changes in color, particularly increased redness, together with edema and an increased tendency to bleed, edema suggest an inflammation (gingivitis) inflammation

143 Teeth (singular, Tooth) are small whitish structures found in the jaws (or mouths) of many vertebrates that are used to tear, scrape, milk and chew food Humans usually have 20 primary teeth (also called deciduous, baby, or milk teeth) and 32 permanent teeth. Among primary teeth, and 32 permanent teeth. Among primary teeth, 10 are found in the (upper) maxilla and the other 10 are found in the (upper) maxilla and the other 10 in the (lower) mandible. Teeth are classified as incisors, canines,premolars and molars. and molars.

144 The main functions of the teeth: Incisors = cutting Canines = tearing Premolars = crushing Molars = grinding

145 The tongue The tongue is skeletal muscle on the floor of the mouth that manipulates food for chewing and swallowing (deglutition).

146 The main functions of the tongue The main functions of the tongue: It moves food around in the mouthIt moves food around in the mouth It begins swallowing action (deglutition)It begins swallowing action (deglutition) It aids in speech productionIt aids in speech production It provides the equipment for taste sensationIt provides the equipment for taste sensation
