Next Review Session is: @ :15 Date: May 31st, 2017- period 1 Aim # 83: What are the structures and functions of the human circulatory system? HW: Test Friday 6/2 (Regents MC!) RRB pages 31-44 due Friday Castle Learning (QUIZ #5) due next MONDAY Do Now: Next Review Session is: @ :15

Why do we need a circulatory system? supplies in fuel (sugars) digestive system oxygen respiratory system waste out CO2

a. Arteries Thick, muscular Carry blood away from the heart Where pulse is felt

b. Veins Carry blood towards the heart Valves prevent backflow

c. Capillaries One cell thick Where exchange of materials takes place by diffusion

Label the vessels below:

Heart

D)

Valves Bicuspid: between left atrium and left ventricle Tricuspid: between right atrium and right ventricle

Circulation your heart pumps 5 liters of blood per minute pulmonary: lungs (5 27  4) c. systemic: body (6 8 1 3) d. Cardiac or coronary: heart

e. lymphatic: filters foreign substances like bacteria from transport fluid i. lymph vessels: tubes that branch through all the tissues ii. lymph: fluid inside vessels iii. blood plasma diffuses through walls of capillaries and forms water fluid around cells of all tissues (ICF: intercellular fluid)

Blood pressure a. systolic: contract b. diastolic: relax c. 120/80

Blood: tissue, because it contains cells; serves as a transport medium to help maintain homeostasis a. Red blood cells Made in bone marrow Contain hemoglobin to carry oxygen b. Platelets Clot blood (enzyme controlled) c. White blood cells Immunity: engulf pathogens, make antibodies Plasma Transports ions, nutrients, wastes, hormones, and proteins

Formation of a clot:

Blood types Antigens: chemicals on the surface of cells, pathogens and viruses that our body recognizes as foreign b. antibodies: made by your body to fight antigens; specific shape c. Blood typing: determined by antigen-antibody reactions

Who is the universal donor? Why? Who is the universal recipient?
