Highlight which of the following functions is NOT a functions of blood. Transport gases, glucose, fatty acids, amino acids, and hormones Distributes and maintains heat Fights pathogens with circulating immune cells and antibodies Digests food molecules Describe an erythrocyte and its functions. Using the letters, match the following from the leukocytes comparison table: a. Neutrophils b. Eosinophils c. Basophils d. Lymphocytes e. Monocytes ______ These cells release histamine and heparin during allergic reactions ______ The highest % of leukocytes which become phagocytes that eat bacteria ______ These cells can become macrophages that go to the site of infection ______ Known as B and T cells which function in immune response Describe the functions of the plasma of the blood. Leukocytes are classified by which 3 criteria of their cells? Examine the slides on blood types in images on slides 14-19 and describe the difference between antigen and antibody as it refers to blood types. In Ex 2, click on the table to identify antigens, antibodies and donors for each blood type. Which blood type is the universal donor? Watch the video demonstration in Ex 3 and complete the table for the final results and the unknowns. Name Mr. Smith Ms. Jones Mr. Green Ms. Brown Blood type Unknowns Blood Vessels List the blood vessels of the systemic circuit that contain oxygenated blood from the heart to the tissues and then and back to the heart. What happens to the oxygen depleted blood that comes into to the heart? In Ex 4: List two major vessels in the neck. List the major vessels that enter and exit the heart Renal artery and renal vein supply and drain blood from the: Which arteries supply blood to the heart muscle? Hepatic portal vein accepts blood from the: Two major arteries in the arm are: A. Blood Vessle Structure List the differences between arteries and veins. Describe the structure and function of capillaries. B. Pulse Ex 6, pulse rate. Human resting pulse averages 70-76 beats/minute. What is your resting pulse? Hold your breathe for 10 sec. Take your pulse Run in place for two minutes. Take your pulse Explain your results: C. Blood Pressure Systolic pressure is in the: Diastolic pressure is when the: Blood pressure device is called: Normal blood pressure is: Heart What structure reduces friction of a beating heart? In Ex 8, draw and label each of the structures of the heart. Use arrows to show the path of blood through the heart. Sign, date and prepare an image of your drawing and include it with this lab report. Trace the path of blood as it flows through the structures of the heart starting with the Superior and Inferior Vena Cava and ending with the Aorta Which conductive node causes the contraction of the ventricles?
