Types of blood cells • Red blood cells (erythrocytes) • contain hemoglobin • carry oxygen • do not have a nucleus • White blood cells (leukocytes) • fight infection • five different types • Platelets (thrombocytes) • control clotting • are fragments of cells
Types of white blood cells • Granulocytes • Have a multilobed nucleus • Contain dark staining granules in their cytoplasm • Consist of: • Eosinophils (3%) • Basophils (<1%) • Neutrophils (50-60%) • Agranulocytes • Have one large nucleus and only a few granules • Consist of: • Lymphocytes (32%) • Monocytes (4%)
Granulocytes • Eosinophils • granules stain red (acidic) • are active • increase in allergic conditions • Basophils • granules stain blue (basic) • function not fully understood • increase in the healing phase of inflammation • Neutrophils • granules stain blue and red/purple (neutral) • phagocytes (engulf and digest bacteria) • called ‘polys’ because of their multilobed nucleus
Agranulocytes • Lymphocytes • Lymph cells • Fight disease by producing antibodies • Attach directly to foreign cells and destroy them • T cells and B cells • Monocytes • Have one large nucleus • Engulf and destroy cellular debris • Leave the bloodstream and enter tissues (e.g. lung and liver), becoming macrophages
Blood diseases / conditions • Anemia • Literally ‘no blood’ • Medically, reduction in • erythrocytes (red blood cells) • amount of hemoglobin in the blood • Aplasticanemia – bone marrow stops producing erythrocytes, leukocytes and thrombocytes • Ischemia • Literally ‘ to hold back blood’ from a part of the body • Ischemic tissue is deprived of oxygen • Can be caused by • mechanical injury • blood clots • collection of fatty material closing off a vessel

Hernias • Hiatal hernia • stomach protrudes into the mediastinum • Inguinal hernia • intestine protrudes into scrotal sac • affects the male • Rectocele • rectum protrudes into the vagina • affects the female • Cystocele • urinary bladder protrudes into the vagina • affects the female • Omphalocele • intestines protrude through the navel • affects infants
Bacterial infections: Streptococcus • Berry-shaped bacteria • Grows in twisted chains • One group causes ‘strep throat’, tonsillitis, rheumatic fever, some kidney ailments • Another group causes tooth and sinus infections, and heart valve infections
Bacterial infections: Staphylococcus • Berry-shaped bacteria • Grows in small grape-like clusters • Can cause external lesions (skin abscesses, boils, styes) • Can cause internal lesions (abscesses in bone and kidney) Abscess = collection of pus, white blood cells, protein. Present at infection sites.
Bacterial infections: Diplococcus • Berry-shaped bacteria • Organised in pairs • Pneumococci cause bacterial pneumonia • Gonococci cause gonorrhea
Medical procedure: Laparoscopy • Minimally invasive • Laparoscope inserted through the abdomen • Carbon dioxide gas infused into the peritoneal cavity • Used to visually examine abdominal viscera • Used to remove the appendix, gallbladder, adrenal gland, spleen, ovary • Used to resection the colon • Used to repair hernias • Used in tubal ligation
